Label data · how much zinc per day supplement

Zinc: mg per serving on every zinc label we carry

Zinc supplements print 15 mg to 50 mg per tablet, while the NIH lists 40 mg a day as the adult upper limit for long-term use — so 50 mg products are short-term labels, not daily ones. The table lists the printed zinc per serving and the form for every zinc product we track.

What to check on the label

  • Milligrams per serving against the NIH upper limit (40 mg/day for adults)

  • Pieces per serving

Long-term intake above 40 mg/day can affect copper status; ask a doctor before taking high doses daily.

Questions people ask

Is 50 mg of zinc a day too much?

It's above the NIH tolerable upper intake (40 mg) for ongoing use; labels that print 50 mg are usually meant for short periods. 15–30 mg products fit daily use better — the table shows each label.

Zinc picolinate vs gluconate?

Both are common; picolinate is marketed for absorption, gluconate is inexpensive and widely used. The milligram number on the label is the comparable part.
