New look. Same formulas.

You probably noticed our new website, new logo, and new product labels. While our looks may have changed, our commitment to science and quality products remains untouched. Every product is still manufactured with the highest quality and safety standards in the world and still contains the exact same formula as before.

Please note that during the transition you might receive products with the former label as well as the new label. In every case, however, all of our products, regardless of label, are shipped with the maximum shelf-life in mind.

Support for a healthy stomach lining and to soothe the mucus membranes of the GI tract*

Pepti-Guard has a particular affinity for the health of the stomach.* It is formulated to specifically support the desirable flora found in the upper gastrointestinal tract*

GI Support
Thorne's Pepti-Guard is formulated to specifically support the desirable flora found in the upper gastrointestinal tract, particularly in the stomach.* Its formula contains deglycyrrhizinated licorice and organic aloe vera for their GI-healing properties.* Only high-quality aloe vera from the inner gel of the aloe plant is used because it soothes and heals the sensitive mucus membranes of the GI tract without causing gastric upset or a laxative effect.* Berberine hydrochloride and bismuth citrate help provide a healthy microbial balance.* The easy eight-week protocol requires just four capsules a day.

Pepti-Guard utilizes DaltonMax 700®, the highest quality aloe vera extract on the supplement market. These are its key advantages:· - It is extracted only from the plant's inner fillet gel, so it has no laxative or irritating effects*
- The low-heat extraction process preserves its bioactive ingredients
- 200:1 strength provides optimal benefit
- It is organic and solvent-free for maximum purity
Take 2 capsules two times daily between meals for a maximum of eight weeks, or as recommended by your health professional.
