HEALTHMIXED
Zinc
Fixes deficiency. Doesn't 'boost testosterone' if you're already replete.
EFFECTIVE DOSE
8–15 mg/day; higher only short-term
HOW IT WORKS
Cofactor in hundreds of enzymes and immune function.
WHAT THE EVIDENCE SUPPORTS
- Corrects deficiency
- Small immune benefit in early cold onset (lozenge, high dose, short duration)
WHAT TO LOOK OUT FOR
- Chronic high-dose zinc (>40 mg) blocks copper absorption.
- Not a stand-alone T booster.
SIDE EFFECTS
- GI upset, metallic taste, copper deficiency with chronic overdose
