Thorne's Gut Health Bundle, contains three best-
selling products to support your gut from all angles.*

What's the difference between a prebiotic
and probiotic?

Prebiotics are types of fiber that help to feed probiotic bacteria. Therefore, a prebiotic supplement helps increase beneficial bacteria in the gut by providing food for them. Probiotics are the actual beneficial live organisms - usually bacteria but sometimes a yeast, such as Saccharomyces boulardii, a species similar to Brewer's Yeast.

Are there any differences between
probiotics for men and probiotics for

Not really. There may be types of delivery systems more suited for women - for example, a vaginal suppository to support good vaginal flora. Along that same line, there are certain probiotics that research shows support healthy vaginal flora even when taken orally - thus, possibly more indicated for women.

What is a human-based strain probiotic?

This is a probiotic supplement that consists of those bacterial strains that are normally found in the human gastrointestinal tract.

Can I take a probiotic at the same time as a
prescription antibiotic?

It is best to take a prescription antibiotic and a probiotic supplement at separate times during the day because some probiotic bacteria can be destroyed by an antibiotic; while others are not. An example of a probiotic that is not destroyed by antibiotics is Saccharomyces boulardii, because it is a yeast and not a bacteria.

Can a probiotic cause gas and bloating?

Because taking a probiotic supplement will change the balance and types of the microorganisms in the gut, as well as the environment in the large intestine, they can create gas in some people. However, this is usually a temporary situation, and the gut tends to normalize in a few days.
