Allergy Research Group Zinc Picolinate Review 2026: Review
It's actually fine. — Legitimate
-
"Superior absorption vs zinc citrate and gluconate"
Barrie et al. 1987 crossover trial confirmed zinc picolinate raised tissue zinc levels more than citrate or gluconate at 50mg.
PubMed: Barrie et al., Agents Actions 1987 -
"25mg dose is therapeutic"
25mg is within the studied range and below the 40mg/day upper tolerable limit — a reasonable, safe maintenance dose.
-
"Supports immune function"
Zinc deficiency impairs T-cell function. Supplementation restores immunity only in deficient people — not a general immune booster.
PubMed: Wessels et al., Nutrients 2017 -
"Long-term zinc use is safe without caveats"
Zinc above 25mg/day long-term depletes copper, causing anemia and neurological issues. Product page does not warn about this.

Consumer advice
Get a serum zinc or ferritin test before buying — zinc supplementation is only clearly beneficial if you're deficient. If you do need zinc, the picolinate form is a legitimate choice with real absorption advantages. However, compare prices: NOW Foods and Thorne both offer zinc picolinate at similar or lower per-serving costs. If you take this long-term, also supplement with 1–2mg copper, as zinc depletes copper over time. Vegetarians and vegans have the strongest case for this product due to lower zinc bioavailability from plant foods.
