Zinc
Essential trace element, involved in over 300 enzymatic reactions. Critical for immune function, wound healing, DNA synthesis, testosterone production, and skin health. Deficiency is widespread in industrialised countries.
How it works
Zinc is an essential trace element and cofactor for over 300 enzymes, central to immune function, wound healing, testosterone metabolism and DNA synthesis. Taken early in a cold, zinc can shorten its duration. Chronically high doses, however, impair copper absorption.
Dosage
10–25 mg/day for ongoing use. Bisglycinate or picolinate offer the best bioavailability. Take with a meal to avoid stomach upset.
Considerations
Doses above 40 mg/day chronically cause copper deficiency. Separate from iron and calcium supplements by at least 2 hours. High zinc doses reduce absorption of some antibiotics.
