Why 16mg of Zinc?

How Zinc works

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.

Key benefits

• Cofactor for 300+ metalloenzymes
• Essential for DNA synthesis and repair
• Supports both innate and adaptive immune function
• Bisglycinate: superior absorption vs oxide form
• 16mg = 160% UK NRV
