Zinc Gluconate: price per 15 mg zinc

We count the elemental zinc a product provides, not the weight of the whole compound it comes in. If a label states the zinc amount, we use it. If it only gives the compound's weight, we estimate using a published conversion factor and mark the figure “estimated”. If we cannot tell which the number means, the product is listed as unverified and is not ranked.

Conversion factor used when only the compound weight is given: gluconate 14.3%. How we chose these.

Prices last checked: 17 September 2026. Ranked purely by price per 15 mg zinc — a comparison unit, not a recommendation. We may earn commission from these links; it never affects the order.
