This **zinc picolinate** delivers 50mg of elemental zinc per capsule for immune support, in one of the most absorbable forms available — but that dose sits above the 40mg daily upper limit for adults, which is the key thing to know here. Zinc's role in immune defense is well-established, and at 50mg you're well past the 15–30mg range used for everyday supplementation.
Taking 50mg daily over time competes with copper absorption, and sustained intake at this level can lead to copper depletion — which can show up as anemia or nerve problems. NOW's own label flags this, noting the product isn't intended for long-term use.
This dose fits short-term therapeutic use, like knocking down a cold, ideally under guidance. If you want a daily zinc, you'd be better served by a lower dose or one paired with copper to stay within the safe ceiling.
