Zinc bisglycinate

Tier 2 — promising · Zinc form · Chelated mineral

Zinc chelated to two glycine molecules, a well-absorbed and gentle-on-stomach form. Head-to-head with zinc gluconate and oxide, bisglycinate typically shows equal or superior absorption and significantly less nausea — the main limit of supplemental zinc. Preferred form for those who cannot tolerate zinc on an empty stomach or who need sustained supplementation. Still subject to the 40 mg/day upper limit for long-term use (higher doses induce copper deficiency over months).

Dose: 15–30 mg elemental zinc as bisglycinate daily (check label for elemental)
