Short answer

15-30mg daily for maintenance. During illness, Andrew Huberman recommends 90-100mg (short-term only, 1-2 weeks). Chronic doses above 40mg/day deplete copper. Mark Hyman puts about 40% of Americans as zinc deficient.

Detailed Answer

15 to 30 mg of zinc a day is the dose for maintenance, though the right amount depends on context. For short-term immune support during illness, Andrew Huberman recommends 90-100mg daily with food, limited to 1-2 weeks.

Safety

Chronic high-dose zinc above 40mg/day depletes copper. Rhonda Patrick warns that excess zinc also blocks magnesium absorption, so keep an eye on both minerals if you take zinc for long.

Forms and helpers

Mark Hyman recommends zinc carnosine for gut healing, as part of his 5R protocol. Patrick explains that quercetin is a zinc ionophore, a molecule that carries zinc into the cell, so pairing the two can improve delivery.
