Best Zinc Supplements 2026: Cost per Effective Dose
15 mg of zinc costs $0.029 to $0.33 at list price across every size we price. The cheapest, Nature Made Zinc 30 mg, is also on a public testing list (USP Verified). 4 of the 7 products are on one. Paying more buys a different form or a different testing list, not more zinc.

4 of the 7 are on a public testing list (NSF/ANSI 173, NSF Certified for Sport or USP Verified). To choose by need, see the best zinc, scored.
Not priced: Klean Athlete Klean Zinc. Klean's store was down when we priced zinc (October 12, 2026), and no other store we use sells it, so we have no list price to compare. It is on NSF Certified for Sport and NSF/ANSI 173. Each chewable tablet has 10 mg of zinc (citrate); the label (dated 2021 in the NIH database) says 1 to 3 a day.
Per 15 mg, or per serving?
Per serving is what you pay each day if you take one, as the labels say. Per 15 mg is fairer when strengths differ: a 15 mg capsule gives half the zinc of a 30 mg one. Most adults need 8 to 11 mg a day, and many get that from food. The upper limit is 40 mg a day from food and supplements together (NIH), so a bigger pill is not a better buy. How much to take.
Amazon’s price can differ from the list prices here.
Most of the pricier products here are glycinate or picolinate. In two small studies, glycinate raised blood zinc more than the gluconate in our pick, but no study we found shows a health difference between forms (glycinate vs picolinate).
