US Rowing Names Thorne Research as its Newest Partner

PRINCETON, N.J. – USRowing is proud to announce that Thorne Research has signed as the exclusive dietary supplement partner of USRowing, providing national team members with effective and safe supplements to support athlete health. As part of the multi-year agreement, Thorne will provide products to U.S. National Team athletes and will offer benefits to the rowing community through a health portal and educational campaign.

Major advances in the research, development and monitoring of dietary supplements has enabled Thorne Research to provide elite athletes with supplements that can aid in overall health as well as accelerate recovery from the day-to-day rigors of training after the athletes’ food and nutrition practices have been maximized. Thorne Research will provide USRowing athletes with products that have the highest level of certification, baseline nutritional level testing through WellnessFX, educational materials and risk protection.

“Our athletes’ health is our highest priority and cannot be placed at risk. Athletes may have nutritional or physiological demands that require supplementation, and USRowing’s partnership with Thorne Research will ensure that our athletes are receiving safe, clean and carefully monitored and tested dietary supplements,” saidDr. Jo Hannafin, USRowing’s team physician. “It is critically important that standards for quality, safety and content be demonstrated for dietary supplements that may be used by our athletes.”

In addition, athletes will have access to reliable health information from Mayo Clinic, which has been compiled for easy access on the Thorne Research website. This content helps athletes evaluate supplement usage and understand supplement labels, manufacturing and regulations, all provided by an objective resource.

“USRowing is synonymous with quality and success. We at Thorne Research are excited to be part of this winning tradition and also take tremendous pride in the quality of our product,” said Paul Jacobson, Thorne Research CEO. “Through this partnership, we look to become an integral part of the health and wellness regimen of these great athletes and the rowing community.”

Eight NGBs Sign Nutritional Supplement Brand

A nutritional supplement manufacturer blessed by the U.S. Olympic Committee has signed sponsor deals with national governing bodies in eight sports, breaking through in a category long suppressed by connections to failed PED tests.

Sandpoint, Idaho-based Thorne Research has deals in place to sponsor U.S. national teams in gymnastics, rugby, triathlon, rowing, pentathlon, fencing, taekwondo and softball, with plans to complete more in both summer and winter sports in the coming weeks, said Tom Shepard, chief marketing officer and partner at 21 Sports & Entertainment Marketing Group, which represents Thorne.

The agreements vary slightly by sport, but all will deliver to athletes and teams Thorne products that have been cleared by the NSF Certified for Sport program, which offers independent testing of products and the facilities in which they are manufactured.

Thorne also will provide NGBs and their athletes with a Wellness FX program that offers customized dietary and workout protocols, which can be tweaked and tracked through blood tests, as well as nutrition-based education programs tailored to athletes in each sport.

Each deal is for two years, with an option for a two-year extension, taking them beyond the coming Rio Olympics. Thorne would not disclose financial terms.

Spurred by athletes’ desire to use supplements, coupled with the fear that those supplements might cause them to test positive for banned substances, the USOC three years ago began a vetting process in search of a product line that it could recommend to competitors. It landed on Thorne, then worked with the company on a program that it could offer to the NGBs.

“The biggest problem with supplements in general is that the stuff geared for high performance tends to be spiked with some sort of drug to generate that performance,” said Paul Jacobson, Thorne Research CEO. “What the athletes are most concerned about is banned substances. At Thorne, we have never allowed anything on the banned substance list in our plant. Ever.”

Thorne’s primary distribution channel thus far has been through physicians who recommend the product to their patients. Working with the NGBs offers a chance to broaden that reach, increasing the brand’s exposure among athletes and their family and friends.

“They’ve chosen this strategy because, from an aspirational standpoint, this is it,” said Shepard, a former Visa marketing executive who structured the deals. “If it’s good enough for an aspiring Olympian, it’s good enough for Joe or Jill weekend athlete. It’s the concentric circle. When you look at a population base like [an NGB’s members] and how they influence those around them, that becomes a big number.”

USOC dieticians worked with Thorne to determine which of the company’s more than 400 products would be submitted for NSF certification and then made available to athletes. Six will be available initially — including an amino acid complex, a fish oil product and a vitamin D supplement — with the product line expanding to 19 by the end of July and 25 by January.

One of the Thorne products will have particular relevance for athletes headed to Rio: a probiotic designed to combat infection, which some say will be a risk for athletes competing in events in polluted waters, such as sailing, rowing, open-water swimming and triathlon.

Triathletes are an especially attractive target market for Thorne, because most already use supplements or would like to do so, said USA Triathlon CEO Rob Urbach. USA Triathlon’s membership of about 500,000 includes not only those building toward Rio, but the many “weekend” athletes who enter one or two events a year but train year-round.

“The supplement category has been a difficult category because of the perceptions of tainted products and potentially false advertising claims,” Urbach said. “The USOC was on a quest to find a supplement partner that they could trust, not so much for a sponsorship or licensing deal, but as a supply source to the athletes who didn’t want to risk ruining their career by using a tainted product.”

Thorne Research Partners with Multiple U.S. NGBs for Sport

New York, June 7, 2016 — In a move to bring the highest level of nutritional science and quality to the well-being of their athletes, elite and professional teams are vetting the most effective and safest nutritional supplements to support athlete health. Seven U.S. National Governing Bodies (NGB’s) have signed partnership agreements with Thorne Research to be their exclusive nutritional supplement partner, and agreements with several additional NGB’s are pending. These multi-year agreements will launch in 2016.

Thorne Research’s participation, in collaboration with the NGB’s coaches, doctors, and sports science specialists, will be integral to the health and wellness programs within these prestigious governing bodies, including USRowing. “Our athletes’ health is our highest priority and cannot be placed at risk. Athletes may have nutritional or physiological demands that require supplementation, and USRowing’s partnership with Thorne Research will assure that our athletes are receiving safe, clean, and carefully monitored and tested nutritional supplements," says Dr. Jo Hannafin, USRowing’s Head Team Physician. “It is critically important to ensure that standards for quality, safety, and content be demonstrated for nutritional supplements that may be used by our athletes,” she says.

As part of the NGB partnerships, Thorne Research will provide the NGB’s National Team members nutritional supplement products with the highest level of certification, baseline nutritional level testing through WellnessFX, educational materials, and risk protection with product liability insurance.  In addition, these elite athletes will have access to reliable health information from Mayo Clinic, which has been compiled for easy access on the Thorne Research website. This content will help athletes evaluate nutritional supplement usage and better understand nutritional supplement labels, manufacturing, and regulation, all provided by an objective resource. Thorne Research is also embarking on several clinical research studies at Mayo Clinic, including the effect of nicotinamide riboside on brain health in collegiate football players, the effect of nicotinamide riboside on altitude acclimatization and team cohesion during an ascent of Mt. Kilimanjaro, and a study of the microbiome in elite athletes.

Steve Penny, CEO of USA Gymnastics, is keenly aware of the unique demands placed on athletes.  Mr. Penny stated, “Athlete performance is a function of many variables, and proper nutrition is a key fundamental element.  The human body is designed to perform at its optimal level when the right balance of nutrients is provided to keep the athlete healthy and strong.  Often times, the competition environment can make it difficult for an athlete to have access to food products that meet their individual nutritional needs, especially when traveling abroad.”

Major advances in the development, medical research, and monitoring of nutritional supplements has enabled Thorne Research to provide elite athletes with nutritional supplements that can assist in accelerating recovery from exercise-induced muscle damage that can result from the day-to-day rigors of training and competition.

“Our partnership addresses a great need on the part of competitive and elite athletes. No longer must these athletes fend for themselves trying to figure out which nutritional supplements to take, and where to obtain a safe, clean, and reliable source of nutritional supplements.  This partnership follows years of hard work by the NGB’s to help the athletes address that problem. We are honored that these prestigious National Governing Bodies are working with us because of our approach to providing nutritional supplements that are scientifically formulated, rigorously studied, clinically researched, and NSF Certified for Sport®,” states Paul Jacobson, CEO of Thorne Research.

As athletes reach the highest levels of competition and become more efficient in their sport, they stress specific groups of muscles day in and day out. This daily process of stress and repair requires that their bodies receive very specific ranges of vitamins, minerals, and botanicals in order to perform optimally. For example, competing in a high-stress environment – that is also away from home – requires nutritional supplement products such as a probiotic supplement that provides optimal balance of good bacteria in the gut, and an iron supplement that promotes the formation of new red blood cells, thus optimizing the body’s ability to carry oxygen throughout the athlete’s body.

Research Highlights on Dietary Supplements

A lot of research is overlooked when it comes to nutritional supplement products, which is understandable because there are more than two million peer-reviewed journal articles published every year. Fortunately, we have reviewed some of the newest and best research results so we can keep you up-to-date on what’s being revealed about the benefits of using nutritional supplement products. 

A recent study found that by supplementing aging mice with nicotinamide riboside, tissue maintenance and regeneration were enhanced and lifespan was increased. Click here for more information.

In a long-term prospective study of male physicians who were initially healthy at the time the study began (18,530 physicians, age 40 or older, from the Physicians’ Health Study), multi-vitamin/mineral use for at least a 20-year period was associated with a lower risk of major cardiovascular disease-related events.

Thorne Research Announces Clinical Study to Assess Nicotinamide Riboside on Brain NAD+ in College Football Players

Mayo Clinic, University of Minnesota and ChromaDex to Collaborate on Study

NEW YORK, April 13, 2016 – Thorne Research and ChromaDex Corp. (OTCQX: CDXC) announced today a research endeavor with Mayo Clinic and the University of Minnesota Clinical and Translational Science Institute, regarding a planned clinical study to assess the effect of Nicotinamide Riboside (NR) on brain NAD+ in college football players.

The randomized, placebo controlled, double-blind study will enroll healthy male collegiate football linemen, not having a history of more than 3 concussions. Participants will take either 750 mg per day of Nicotinamide Riboside (NR) or placebo for 84 days. Pre- and post-intervention evaluations include physical assessment, blood tests for safety and toxicity monitoring, blood tests for biomarkers, neurologic testing, quality of life questionnaires, and real time measurement of brain NAD, using 31P MRS.

The primary outcome of the study is to measure the change in brain NAD+ levels over 3 months. The study is expected to begin in May 2016 with final data collected by March 2017.

The study will utilize advanced 7 Tesla in vivo 31P Magnetic Resonance Spectroscopy (MRS) for noninvasive measurement of brain NAD+ concentrations, NAD+/NADH ratio, and ATP, using a method pioneered by Xiao-Hong Zhu, Ph.D., Associate Professor the University of Minnesota Center for Magnetic Resonance Research.

The principal investigators of the study are Dr. Zhu and Brent A Bauer, MD, Director of the Well Living Lab and Director of the Complementary and Integrative Medicine Program at Mayo Clinic in Rochester, Minnesota.

Paul Jacobson, CEO of Thorne Research, stated, “We now have data showing that nicotinamide riboside raises NAD+ in the blood and in the brains of animals. We have further evidence that NR raises NAD+ in white blood cells and in plasma in humans. This will be the first trial to examine whether NR raises NAD+ in the brains of humans. Since concussion activates the DNA repair enzyme PARP-1 (which consumes and lowers NAD+ in the brain), the possibility that NR might raise brain NAD+ levels opens an exciting new frontier in how we might be able to manage football-related concussion and other forms of traumatic brain injury in the near future.”

Frank Jaksch Jr., founder and CEO of ChromaDex, commented “We are honored to collaborate with Dr. Zhu and Dr. Bauer and their respective research teams, as well as Thorne Research on this clinical trial. The human study is designed to provide a better understanding on how NR may affect brain NAD+ levels in athletes who participate in football and other contact sports.”

Thorne Research introduced NiaCel® in 2014, which features ChromaDex’s patented ingredient NIAGEN®, the first and only commercially available form of nicotinamide riboside (NR), a naturally occurring vitamin B3 metabolite found in milk.

ChromaDex, through more than 50 collaborations with researchers around the world, is in the forefront of research showing that the use of NR helps preserve or restore mitochondrial function and may be beneficial in treating and/or preventing disease.

About Nicotinamide Riboside (NR)

Published research has shown that NR is perhaps the most effective precursor to boost the co-enzyme NAD+ in the cell. NAD+ is arguably the most important cellular co-factor for improvement of mitochondrial performance and energy. In recent years, NAD+ has been shown to be essential in supporting healthy cellular metabolism, including the efficient conversion of blood glucose into energy.

As organisms age, NAD+ levels drop, which leads to a decrease in mitochondrial health; this in turn leads to age-related health issues. Low NAD+ levels limit activity of a group of enzymes called sirtuins, which are believed to play a key role in longevity. NAD+ levels can be depleted by lifestyle choices such as overeating and lack of exercise. By boosting NAD+, NR can increase mitochondrial health and induce creation of new mitochondria.

It’s All About NAD

Why NAD?

As research reveals more information about metabolism and aging, we increasingly find at the center of this complex web of enzymes and biochemical markers a coenzyme found in all living cells – nicotinamide adenine dinucleotide (NAD). The amount of NAD in the body declines naturally with aging, and in doing so the activities of numerous enzymes are correspondingly decreased. The sirtuin (SIRT) family of proteins, which rely heavily on the presence of NAD, have been studied for many years for their role in metabolism and aging. To date, seven SIRT protein subtypes have been identified, each of which have a slightly different activity, location, and overall function. Because SIRT activity is dependent on NAD, these two compounds are linked to cellular lifespan, metabolism, and even regulation of inflammation.

Because NAD pools decline naturally during the aging process, SIRT function will decline as well. A decline in SIRT1 activity will impact mitochondrial function in two ways.  First, a decline in SIRT1 has been linked to decreases in mitochondrial biogenesis via transcriptional activator PGC1α.  Second, decreased SIRT1 activity leads to decreased mitochondrial function due to a reduction in mitochondrial DNA replication and transcription. Because the mitochondria are the energy powerhouses in every cell of the body, a decline in mitochondrial function has now been linked to many age-associated pathologies, including metabolic syndrome, obesity, neurodegenerative issues, and cognitive decline.

Since one in three adults has metabolic syndrome, the importance of the SIRT family of proteins to metabolism cannot be over-emphasized. A recent study found that individuals with fatty liver who had a specific single nucleotide polymorphism (SNP) for SIRT3 were more likely to progress to metabolic syndrome.

How do we increase NAD?

What can we do to increase NAD in the body? It turns out that recent clinical research has found that nicotinamide riboside (NR) – a newly-researched vitamin B3 analog – can increase NAD levels in healthy humans – indicating that NR crosses into the mitochondria and increases NAD levels.* Click here for more information:

How does NR affect metabolism?

The use of NR to increase NAD has been studied in animal models of metabolic syndrome. Because NR leads to increased SIRT1 and SIRT3 activity, the clinical ramifications for human use are extensive, and include: (1) a decrease of fatty liver incidence from a high-fat, high-sucrose diet; (2) a decrease in hepatic insult in models of type 2 diabetes; (3) an increase in cholesterol metabolism through SIRT1 activation; and (4) better weight management in high-fat diets.*

To summarize, NR can increase NAD, which can upregulate SIRT1 and SIRT3.*

Increased SIRT1:

  • inhibits hepatic glucose formation in obesity*
  • limits hepatic lipid accumulation in the presence of elevated blood sugar*
  • promotes the production of good (HDL) cholesterol*
  • supports insulin release, improving overall glucose tolerance*
  • enhances leptin sensitivity*

Increased SIRT3:

  • inhibits lipid accumulation in the liver*
  • increases mitochondrial biogenesis in skeletal muscle*
  • increases thermogenesis in brown fat stores*

The bottom line – it’s all about NAD!

Pain in the Gut: How NSAIDs and Gut Microbes Can Affect Each Other

Understanding how medications are metabolized in the human body continues to be one of the fastest growing – and most fascinating – areas of medical research. This research includes understanding what the body does to a medication when it’s ingested – pharmacokinetics – as well as what that substance does once it’s in the body – pharmacodynamics. As we more intensely study the human genome, we are beginning to appreciate its complex and closely intertwined relationship to these areas of human physiology – what is increasingly being referred to as pharmacogenomics.

The interaction model is not yet fully complete, particularly because we need to increase our understanding how and where epigenes and epigenomics fit into it. Notwithstanding our current understanding of what the body does to an ingested substance on a genetic level, there are still a multitude of interactions we are not aware of. The newest category of interactions could be referred to as pharmacomicrobiomics – what our unique microflora arrangement will do to a substance and vice versa. Some of the very latest research is just now beginning to address this subject.

In a recently published article in the open-access scientific journal, eLife, a group of researchers began analyzing two significant interactions – how an ingested substance might change the microbiome and the effects the microbiome might have on the metabolism of the substance. The team had studied the medication indomethacin, a common medication in the non-steroidal anti-inflammatory drug (NSAID) class, which is related to ibuprofen and naproxen. Indomethacin inhibits two enzymes that produce prostaglandins, which results in an anti-inflammatory effect in the body.

But the prostaglandins that are being inhibited are in the body for a reason – they provide protection from gastric ulceration. In the first part of the study, the research team found that acute and chronic dosing of indomethacin in mice significantly altered the microbiome genomic structure such that it created a more pro-inflammatory architecture. At both dosing schedules for indomethacin – short-term and long-term – pro-inflammatory changes were observed in the GI tract. Therefore, a common side effect of indomethacin therapy, which can occur with short-term and long-term dosing, can be gastric ulceration. 

In the second part of the study, the research team treated the mice with antibiotics, then studied the pharmacokinetic and pharmacodynamic effects the altered microbiome had on indomethacin. What they observed, most likely due to bacterial enzyme changes, was that there was a higher elimination/clearance of the medication, as well as a reduction of its half-life, which would reduce its anti-inflammatory effect.  Although this might help decrease the adverse effect related to decreased prostaglandins in the gut, the decreased systemic concentration of the drug would also likely reduce its anti-inflammatory effects. These interactions would therefore result in so-called bi-directional interactions.

Although this study was done in mice, the authors concluded that, “Humans show considerable inter-individual differences in their microbiota and their responses to indomethacin – thus the drug-microbe interactions described here provide candidate mediators of individualized drug responses.”

Heart-Healthy Practices: Surprising Statistics

Heart disease is currently the leading cause of death in the United States. According to the latest statistics from the U.S. Centers for Disease Control, heart disease results in 600,000 deaths each year, accounting for one of every four U.S. deaths. This is a somber statistic and it suggests most people have been affected by, or have a family member with, or have suffered a loss of a loved one from heart disease. But there is hope. As you probably know heart disease can be prevented.

In a large study known as the CARDIA study, researchers following 18-30 year-olds from the mid 1980’s to the present analyzed large amounts of data to identify cardiovascular disease (CVD) risks. What they found is quite amazing.

In a study published in 2012, it was shown that positive diet and lifestyle factors followed by young adults reduced their risk of CVD as they got older. These positive factors include a normal body mass index, limited alcohol intake, no smoking, a healthy diet, and regular physical activity. These results were found even in individuals who had a family history of heart disease – meaning nurture trumped nature!

Further analysis of the CARDIA study reveals fruit and vegetables play a significant role. Those individuals with the highest fruit and vegetable intake were shown to have the lowest coronary artery calcium on follow-up after 20 years. Coronary artery calcium is a hallmark marker for sclerotic plaque formation and CVD risk. Further studies also link shorter sleep duration to CVD risks in men. The findings show that men who have shorter objective sleep durations have a significant increased risk of CVD.

So why bring this up? To some these facts will appear to be a no brainer, but this couldn’t be further from the truth. An analysis presented at the 2015 annual American Heart Association meeting found that fewer Americans are sticking to heart-healthy practices than 20 years ago. Even with the mounting evidence we now have regarding the power of prevention for heart disease, less than six percent of the 3,460 individuals in another large longitudinal study known as the Framingham heart study were still following the guidelines for preventing cardiovascular disease.

So, to celebrate heart month, let’s focus on prevention as well as supporting cardiovascular health with short- and long-term heart healthy goals. All month long we will increase our diet, health, and lifestyle educational content as a way to help kick-start positive cardiovascular health goals for you and your patients.

New England Journal of Medicine Article Claims Supplements Unsafe

An article in the October 15, 2015, New England Journal of Medicine, and quoted by numerous media outlets, reported there are an estimated 23,000 hospital emergency department visits annually in the United States due to the use of dietary supplements.  The estimate was obtained by gathering data from 63 hospital emergency departments, which reported 3,667 visits attributable to dietary supplements over a 9-year period (2004-2013).  That number was extrapolated to all U.S. hospitals, which is how the estimate of 23,000 annual ER visits was derived.

The largest portion of ER visits (41%) was related to weight loss, energy, and sexual enhancement products, with the most commonly-reported symptoms being palpitations and chest pain.  These three categories have long been a problem, with numerous products that claim to be dietary supplements being adulterated with prescription drugs or their chemical analogs.  Other products have been shown to contain stimulant drugs or caffeine – which can cause adverse reactions when taken in high doses or by susceptible individuals.  In the 20-34 age demographic, weight loss and energy products were implicated in more than 50 percent of cases.  Unsupervised ingestion by children accounted for 21 percent of cases.

It’s difficult to determine whether the estimated 23,000 ER visits is a correct number.  To arrive at an accurate estimate of ER visits attributed to reputable supplement products you should back out the above categories of spurious products, as well as the accidental ingestion by unsupervised children and the elderly – 67 percent of the reported cases in children and 62 percent in those 65 and older.  A large portion of the elderly cases was due to swallowing difficulties of large tablets or capsules, but were attributed to the intake of “micronutrient” supplements.  The researchers in the NEJM article didn’t state how many elderly individuals had difficulty swallowing large tablets or capsules, but this issue is problematic in attributing them solely to supplements, because the symptom is more related to the dosage form than the contents.  Even if the 23,000 ER visits estimate is correct, this equals only 4.6 patients per year reporting to the ER of their local hospital for an adverse event related to using a dietary supplement.  This also equals only one percent of the ER visits attributed to the proper use of prescription drugs.  According to a U.S. Health and Human Services report, 2.3 million individuals visited hospital emergency departments in 2011 for adverse events related to the proper use of prescription drugs.  Over 100,000 individuals die each year from prescription drug use.  These contrary facts point to an excellent safety record for legitimate dietary supplements.

Thorne Research takes every adverse event report seriously.  Every adverse event report is handled by an independent company that specializes in adverse event data gathering, investigation, and reporting. Adverse events are reviewed, investigated, and reported to FDA if they are deemed to be a Serious Adverse Event.  We regularly analyze adverse event reports for product, ingredient, or symptom trends, and we perform risk analyses to ensure the safety of our products.  The data reported by our independent adverse event partner shows a 0.007 percent potential risk (seven one-thousandths of one percent) of having an adverse event per bottle of a Thorne Research supplement, which equates to a 0.0002 percent potential risk (two ten-thousandths of one percent) of experiencing an adverse event from one dose of one of our supplement products – a 1 in 457,068 chance.  And the majority of these reported adverse events are gastrointestinal in nature, mild, and self-limited.


  • Thorne Research has a robust adverse event reporting program.
  • The risk of an adverse event cause by a reputable supplement product is less than one percent of having an adverse event caused by a prescription medication.
  • An independent, third-party company that specializes in adverse event information gathering, investigation, and reporting handles our adverse events.
  • We perform a thorough trend analysis of our adverse event reports.
  • The risk of experiencing an adverse event from a Thorne Research product is incredibly small.
Physician Provides Data on Americans’ Alarming Nutrient Deficiencies at Congressional Dietary Supplement Caucus Briefing
CDC data show that Americans don’t get sufficient essential nutrients from food alone
WASHINGTON (Sept. 11, 2015) — Data from the Centers on Disease Control and Prevention (CDC) show that tens of millions of Americans aren’t getting enough essential nutrients to ensure their bodies function optimally, a stark contrast to headlines and soundbites that assert Americans get the nutrients they need from food alone.

The CDC data was presented by Tieraona Low Dog, M.D., nationally recognized physician, author and speaker, to congressional staffers at a Sept. 9 educational briefing, “Life Fortified: A Physician’s Case for Dietary Supplements,” held by the Congressional Dietary Supplement Caucus (DSC) in cooperation with the leading trade associations representing the dietary supplement industry: the American Herbal Products Association (AHPA), the Consumer Healthcare Products Association (CHPA), the Council for Responsible Nutrition (CRN), the Natural Products Association (NPA), and the United Natural Products Alliance (UNPA).
Citing CDC data, Dr. Low Dog highlighted that nearly 90 million Americans have a vitamin D deficiency, 30 million Americans are deficient in vitamin B6, 18 million Americans are deficient in vitamin B12 and nearly 16 million Americans have a vitamin C deficiency.
“I’m extremely concerned when I hear misleading soundbites on the evening news that people don’t need vitamins because they get all the nutrients they need from their diet because it isn’t just patients who hear this, doctors also hear it repeatedly,” Dr. Low Dog said. “This mantra that Americans get all the nutrients they need from food is simply not true and the data demonstrates it is false. It is much harder than you think to get the nutrients you need from food alone.”

Dr. Low Dog illustrated this point by outlining what the average person would need to eat in order to get the minimum recommended amount of many individual nutrients. For example, in order to get the recommended 18 milligrams of iron per day through food, you’d need to eat four cups of raisins, 15 cups of broccoli, three cups of cooked spinach, 10 ounces of beef liver, or 45 ounces of chicken breast. She noted that meeting the minimum amount of nutrition is especially difficult for low-income Americans who can use Supplemental Nutrition Assistance Program (SNAP) assistance to purchase candy and soda, but not multivitamins.

A thoughtful, coordinated approach between industry and public health initiatives is required to address the many complex factors like lower nutrient content in today’s foods and unintended consequences of well-intentioned health campaigns to avoid certain, nutrient-rich foods like egg yolks that contribute to Americans’ vitamin and mineral deficiencies, according to Dr. Low Dog.

Magnesium Helpful for Pregnancy-Induced Leg Cramps

Leg cramps are common in pregnant women and are very uncomfortable. In a double-blind, placebo-controlled, four-week trial of magnesium supplementation in 86 healthy pregnant women, leg cramp frequency and severity were studied. In the group who took 300 mg magnesium daily, significant reductions were demonstrated in leg cramp frequency and intensity compared to placebo.

Computer-Related Dry Eyes Relieved by Fish Oil

While too much computer screen time can cause dry eyes, recent research has shown that intake of omega-3 fatty acids from fish oil can help dry eye symptoms. In a study of 478 people with dry eyes who spent significant amounts of time at the computer, a fish oil supplement improved their dry eye symptoms. In the individuals in the study who took a modest amount of fish oil daily – 360 mg of EPA and 240 mg of DHA – 70 percent were symptom-free after three months. In the placebo group, only 15 percent had symptom relief.

Skipping Breakfast - a Risk Factor for Heart Disease

Everyone knows that the types of foods you eat have a major impact on your health. As it turns out, when you eat could be almost as important. A new study published July 23, 2013, in the journal Circulation revealed that men who skip breakfast are 27 percent more likely to develop heart disease than men who begin each day with a meal. And men who eat late at night have a 55 percent higher risk for cardiovascular disease than those who go to bed on an empty stomach.

Previous trials have shown that adults who skip meals are more likely to exhibit certain cardiovascular risk factors, such as excessive body weight, hypertension, dyslipidemia, insulin resistance or type 2 diabetes. Habitually skipping breakfast, for example, can increase your chances for significant weight gain by 15 percent and heighten your risk for type 2 diabetes by over 20 percent. Until now, however, no study has linked poor eating patterns to coronary heart disease.

While people who skip breakfast may also engage in other behaviors that increase cardiac risk – smoking, physical inactivity or consuming too much alcohol, for example – missing the most important meal of the day might confer some physiologic costs that are independent of these behaviors. Compared to people who spread their daily energy intake over three or more meals, individuals who consume all of their daily caloric needs at one sitting tend to have higher LDL-C, triglyceride, apolipoprotein-B and blood pressure levels.

Finally, breakfast is more likely than any other meal to be composed of healthier foods, such as yogurt, fruit or whole-grain cereal or breads. When these foods are chronically supplanted by less wholesome items, the undesirable effects begin to stack up.

Can Targeted Supplementation Reduce Health Care Costs?

Critics of the dietary supplement industry are quick to point out studies that suggest supplements don’t work and are a waste of consumers’ money. But if health-care policymakers become aware of a study published last year in the Journal of Dietary Supplements, such criticism could finally be relegated to the dustbin. According to Drs. Christopher Shanahan and Robert de Lorimier, who collaborated with Frost & Sullivan’s Health Care and Life Sciences Team to gather data for the study, the routine use of omega-3 supplements and B vitamins by individuals who have coronary heart disease could save billions of dollars in health care costs. Those are the kinds of numbers that change the way doctors practice medicine.

Coronary heart disease (CHD), a condition that affects 16 percent of Americans over the age of 55, causes 385,000 deaths and accounts for one of every six fatalities in the United States each year. The hospital-related costs for treating CHD patients now surpasses $100 billion per year, with costs for individuals over age 55 accounting for 60 percent of that figure. In order to determine whether the daily use of supplements at preventive intake levels could impact the financial burden of CHD-related events, Shanahan and de Lorimier analyzed 17 peer-reviewed, published studies evaluating the relationship between omega-3 or B vitamin supplementation and CHD-associated hospital utilization costs.

According to these researchers, if all Americans over the age of 55 with CHD took an omega-3 supplement every day, the average savings in avoided hospitalization costs would be over $2 billion annually. For users of B vitamins (specifically B6, B12 and folic acid), the savings for CHD-related hospitalizations would average $1.52 billion per year. Over the eight-year period from 2013 to 2020, after accounting for the cost of the supplements, the country would realize a net savings of more than $9 billion if everyone in this high-risk group used both omega-3s and B vitamins – that’s money America’s health insurance companies (not to mention its citizens) would like to keep in their pockets.

Drs. Shanahan and de Lorimier designed their study to examine the societal impacts associated with targeted supplementation in an at-risk population. What they couldn’t fully explore were the benefits individual CHD patients might reap from consuming a few dollars’ worth of supplements every month. Despite the lack of this additional information, it seems reasonable to assume that, in addition to saving money by staying out of the hospital, people with CHD stand to gain something even more valuable from supplementation: improved quality of life.

Vitamin D Insufficiency May Impair Athletic Performance

Almost every schoolchild knows that vitamin D – the "sunshine vitamin" – is important for building strong bones. After all, for nearly five decades following its discovery, scientists believed vitamin D was primarily involved in regulating calcium absorption and maintaining skeletal health, and most people still think of it that way. Within the last 40 years, however, researchers have learned that vitamin D behaves more like a hormone than a vitamin, and scientists are currently exploring its roles in electrolyte metabolism, protein synthesis, immunity, nerve and muscle function, and an array of other physiologic processes.

Over 75 percent of Americans could be vitamin D "insufficient", meaning they get enough vitamin D to avoid deficiency but not enough to maintain optimal healthy levels. In elderly individuals, vitamin D insufficiency has been linked to muscular weakness, poor balance, delayed reaction time, and a higher risk for falls and fractures. A review in the May 2013 issue of Nutrients suggests that even mildly low vitamin D levels can adversely affect young people, too, and such insufficiency could be particularly consequential in athletes. According to Dana Storlie-Ogan, a nutritionist at Central Washington University in Ellensburg, Washington, athletes who do not get enough vitamin D might find their performance lagging, they may require longer recovery times, and they could be more prone to stress fractures and muscle injuries. Athletes who participate in indoor sports are especially likely to develop vitamin D insufficiency.1

The average person needs at least 3,000 to 5,000 IU of vitamin D every day.2 Since vitamin D participates in metabolic pathways that are "up-regulated" during exertion, physically active people require more vitamin D for peak performance. Storlie-Ogan advises athletes to have their vitamin D status evaluated and adjust their vitamin D intake to maintain a serum 25(OH)D level above 40 ng/mL.

Extract from Broccoli Can Temporarily Alleviate Autism Symptoms

Autism spectrum disorder (ASD) is a condition that affects 1 in 68 persons in the United States. ASD is characterized by deficits in communication, impaired social interaction, and repetitive or obsessive behaviors. Boys are four times more likely than girls to suffer from ASD. The cause(s) of ASD are unknown, although genetic factors and environmental factors both appear to be involved. The level of disability associated with ASD ranges from mild to severe.

At the present time there is no cure for ASD, so treatment is aimed at relieving specific symptoms and improving an affected individual’s function. Interestingly, many parents of autistic children report that ASD symptoms temporarily improve when their children develop a fever. The factors involved in this so-called “fever response” have not yet been identified, although some experts believe that a fever can awaken one or more protective mechanisms within the brain that are otherwise dormant in individuals with ASD. As a result of recent research on broccoli sprout extract conducted at Massachusetts General Hospital’s Lurie Center for Autism, we might be one step closer to understanding why fever can alleviate the symptoms of ASD, which could lead to new treatments.

In a Massachusetts General Hospital clinical trial involving 44 young men with ASD, daily administration of sulforaphane – an extract derived from broccoli sprouts – substantially improved behavior and communication in the young men who received the treatment. Individuals who received only a placebo showed no improvement. When the treatment group stopped taking sulforaphane at the end of the trial, they returned to pre-treatment status, indicating that it was the sulforaphane that reduced the ASD symptoms in these individuals.

Sulforaphane is known to positively impact many of the physiologic abnormalities associated with ASD, such as excessively high oxidative stress, poor mitochondrial function, and inflammation within nerve cells. According to the scientists at Massachusetts General Hospital, sulforaphane probably triggers cellular processes that mimic the fever response in individuals with ASD. Although this research is only preliminary, it provides valuable insight into the underlying mechansims of a complex disorder.
