Zinc Citrate 25mg from Allergy Research Group delivers elemental zinc in citrate form—a well-absorbed organic salt that supports immune function, skin integrity, and normal reproductive health. Formulated for adults seeking reliable daily zinc repletion without high-dose supplementation.
Why It's Worth Considering: Allergy Research Group has long supplied the practitioner market with clean, excipient-minimal formulations; this 25mg citrate dose sits at a practical level for maintenance support without routinely exceeding tolerable upper intake thresholds.

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.
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).
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.
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.
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.
