Expert Positions
The Verdict
All 5 experts view zinc as an essential mineral, though their depth of coverage varies significantly. Hyman is the most prolific advocate, citing zinc across immune function, gut healing, brain health, skin health, fertility, and detoxification. Huberman recommends 90-100mg zinc for cold prevention and includes it in fertility protocols. Patrick highlights zinc's role in immune defense, cold duration reduction, and its interaction with quercetin as a zinc ionophore. Attia mentions zinc as a critical micronutrient for testosterone optimization. Johnson includes zinc indirectly through his nutrient-dense diet but does not feature it as a standalone supplement.
Where They Disagree
Huberman recommends a relatively high dose of 90-100mg zinc daily for cold prevention, while most clinical guidelines and other experts suggest 15-40mg for maintenance — the higher dose carries risks of copper depletion if used long-term.
Hyman emphasizes zinc supplementation as broadly necessary due to widespread deficiency, while Attia takes a more targeted approach, recommending zinc optimization specifically for testosterone support and only after confirming deficiency through testing.
