Thorne's Zinc Bisglycinate delivers 30 mg of zinc in a chelated bisglycinate form, where zinc is bound to two glycine molecules to support enhanced absorption and gastrointestinal tolerability.

More category questions
How much zinc should I take daily?
For maintenance, 15-30mg of elemental zinc daily. For immune support during illness, up to 50mg for 1-2 weeks. The tolerable upper limit is 40mg/day for long-term use. Always balance with 2mg copper per 30mg zinc to prevent copper depletion.
What is the best form of zinc?
Zinc picolinate has the highest bioavailability in clinical studies. Zinc bisglycinate (chelated) is the most GI-friendly. Zinc carnosine is specifically indicated for gut healing and H. pylori. Zinc gluconate is primarily used in cold lozenges for topical throat contact. Avoid zinc oxide (poorly absorbed).
Can zinc help with acne?
Yes. Multiple studies show 30mg zinc gluconate or picolinate daily reduces inflammatory acne by 30-50% over 3 months. Zinc reduces sebum production, fights acne-causing bacteria, and modulates inflammation. It's comparable to low-dose antibiotics for mild-moderate acne.
Should I take zinc on an empty stomach?
No — zinc on an empty stomach commonly causes nausea. Take with food. However, avoid taking with high-phytate foods (whole grains, legumes) or calcium-rich foods as they reduce zinc absorption. A small meal with some protein is ideal.
Does zinc affect testosterone?
In zinc-deficient men, supplementation can significantly increase testosterone (one study showed a 73% increase over 6 months of repletion). In men with adequate zinc, the effect is minimal. Zinc supports the enzyme 5-alpha reductase and is concentrated in the prostate gland. Athletes who sweat heavily often have marginal zinc status.
