Zinc Bisglycinate

16mg

Required for 300+ enzyme reactions, DNA repair, immune function, and testosterone synthesis. Bisglycinate form has significantly superior absorption vs zinc oxide. 16mg = 160% UK NRV.

Category Micronutrients
Dose 16mg
Form Chelated - Albion TRAACS grade
Evidence Level Strong - extensive human data, EFSA approved

Mechanism

Zinc is a catalytic cofactor for over 300 metalloenzymes including RNA polymerase, alkaline phosphatase, and superoxide dismutase. It is essential for DNA synthesis and repair, protein folding (zinc finger proteins represent ~10% of the human proteome), and immune cell development - both innate and adaptive immunity are profoundly impaired by zinc deficiency.

Zinc bisglycinate (zinc chelated to two glycine molecules) has significantly superior bioavailability vs zinc oxide - the form used in most budget supplements, which has absorption rates as low as 11%. The Albion TRAACS chelation protects zinc from competing mineral absorption and phytate binding in the gut. 16mg provides 160% of the UK NRV of 10mg.

When to take it

With food. Evening can synergise with magnesium for sleep and recovery. Avoid taking simultaneously with high-phytate foods (wholegrains) which inhibit zinc absorption.
