What is the cheapest NSF certified zinc?
Our picks, by labeled strength, with a link to buy them: see where to buy. A strength with nothing certified at it has no pick, and is not listed there.
At 11 mg, NSF names one package we price: BulkSupplements.com Zinc Picolinate Softgels 11 mg (240 count), at $0.136 before delivery. At 15 mg, NSF names one package we price: Momentous Zinc (60 capsules), at $0.333 before delivery. At 30 mg, the cheapest is Core Med Science Zinc 30 mg (60 capsules), at $0.142 before delivery.
4 of the 30 zinc products we track have their exact package named in NSF's Certified for Sport database. That is a stricter test than “the brand is NSF certified”, and it is deliberately so: NSF lists package sizes against each certificate, and a size it does not name is not one it has stood behind. Each price is delivered where the retailer publishes a delivery rate and before delivery where it does not, and each row says which. This page counts NSF's Certified for Sport database only, because its listings name the package size, which lets us check the exact package on sale. Informed Sport and Informed Choice list products rather than package sizes, a different way of answering the question rather than a lesser one.

NSF's listing names another package
NSF lists this product, and the listing names a package size other than the one we price. NSF has not put its name to this package.
- Thorne Zinc Picolinate 30 mg (180 capsules) ($0.114 per 15mg, delivered)
Cheapest at each strength among the 4 zinc packages we track that NSF names at the exact package, not the cheapest that exists. NSF certifies zinc from more brands than we carry, and our catalog is extended brand by brand, so a certified product we have not added yet cannot appear here however cheap it is.

Where to buy: the pick for each type
The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows.
How these lines are chosen
Among 1 product and 1 retailer listing we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below. No product here that clears every other bar publishes a delivery rate below its free-delivery threshold, so the pick is priced before delivery.

A pick has to be independently certified, at the exact package sold where the certifier names packages, with no recall or failed test, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving. Where the retailer publishes no delivery rate, the pick is priced before delivery and says so. Nothing we track here clears all of those yet. Each of these misses at least one bar, and says which:

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
