Thorne Zinc Bisglycinate 15mg is a highly absorbable zinc supplement that provides a gentle, well-tolerated 15 mg dose of this essential mineral in each capsule. Zinc is bound to two molecules of the amino acid glycine, forming a true amino acid chelate that is easy on the stomach and readily absorbed without competing with other minerals. It supports everyday immune function, healthy skin and eyes, and normal hormone metabolism.

Why This Supplement Works

Zinc is an essential trace mineral involved in more than 200 enzyme reactions, from immune defence to cell growth and antioxidant activity. Many common zinc forms are poorly absorbed and can upset the stomach. Thorne uses TRAACS Zinc Bisglycinate, a stable chelate that stays intact through digestion, so more of the mineral is available for the body to use. The glycine carrier is naturally gentle and well tolerated, which makes this form a practical choice for consistent, long-term daily use.

How to Take

Take one capsule one to two times daily with food, or as recommended by your healthcare practitioner. Because zinc can reduce copper absorption over time, long-term use is often paired with copper in a balanced ratio. If you are pregnant or nursing, or take other medicines, speak with your doctor before use. For the best tolerance, take it alongside a meal rather than on an empty stomach.

Who It's For

This 15 mg dose suits adults looking for a gentle, everyday zinc to support immunity, skin, eyes and general wellness, and is a good option for those prone to stomach upset from stronger zinc forms. If you need a higher intake, Thorne also offers a 30 mg version. As a dietary supplement, it is not intended to diagnose, treat or cure any condition.
