Zinc is a trace mineral in a few hundred enzymes. Immune cells use it. So do taste, skin, and wound repair. A lot of people run a little low, especially if they eat little meat and little shellfish. The failure mode is the opposite: a 50 mg pill, every day, for a year, which crowds out copper and is more than a gap-fill. The capsule on this page is 15 mg. That is near the daily need, not a megadose.
What the mineral actually does
The adult RDA is 8 mg for women and 11 mg for men. The upper level used on labels is 40 mg a day from all sources. Fifteen milligrams covers a shortfall. It does not cover a medical deficiency, and it is not a cold cure you start on day four. Lozenges taken early in a cold have a small, messy file. A daily capsule is a nutrition gap, the same category as vitamin D if you are low. On immune work, sleep and not adding a fourth hard session still beat the mineral.
Picolinate and bisglycinate are the forms that absorb more reliably than oxide. Oxide is the cheap salt in discount multis. Gluconate is in the middle. If a label says 50 mg of zinc oxide, you are buying a number, not a plan. Take zinc with food if it nauseates you on an empty stomach. Keep it away from iron, calcium, and the antibiotics that bind minerals (tetracyclines, quinolones). A few hours of separation is the boring fix.
Copper, and who should not freelance this
Months of zinc without any copper in the diet or the multi can drop copper. Thorne’s own note is a zinc-to-copper ratio around 15 to 1 if you stay on it. A multi that already has 15 mg of zinc means this capsule is a double. Read the panel you already own before you add a second. Nasal zinc gels are a different product and a bad one. This is a swallowed capsule.
Pregnancy belongs with the person managing it. Wilson’s disease is a hard no. On supplementation this sits with the gap-fills, behind food. Oysters and beef are still zinc. The bottle is for the week you did not eat them.
