Upper intake level
Adults, 40mg a day, from food and supplements together. One serving of this product holds 15mg, less than that level on its own.
An upper intake level is the largest daily intake unlikely to cause harm for most people. It is not a limit on treatment. It does not apply to someone taking zinc as a medical treatment. It is not a recommendation about what to take.

- Elemental zinc as printed on this package's own panel: "Zinc (as TRAACS Zinc Bisglycinate Chelate) 15 mg 136%", with the footnote "This product uses Albion's TRAACS Zinc Bisglycinate Chelate. TRAACS is a registered trademark of Albion International, Inc." It is not derived from a salt weight, which the panel does not print. The panel carries no "Servings Per Container" line; the serving is one capsule and the front face prints "60 CAPSULES", which is the servings figure recorded here. The page's own ingredient table writes the same line as "Zinc (Bisglycinate Chelate)"; the panel's wording is what is recorded.

Price history
Latest recorded price: $15.00 at Thorne (direct), checked . Unchanged since we started checking on Sep 20 (27 checks).
We check each price about once a day, so this is the range we recorded, not necessarily every price there has been. It says what changed, not why, and nothing about where the price goes next.
Verification, Tier C: Claimed, not confirmed
Two different things reach this level, and the product page says which. Either the label or the product page names an independent third-party program, such as NSF Certified for Sport, NSF Contents Certified or Informed Sport, and we have not confirmed a listing for this package in that program’s own database; or the only test results available are ones the manufacturer or a lab it commissioned published, which may well be accurate and is simply not independent. A mark printed on a package is not the same thing as a listing anyone can open, and that gap is what this level records. It is not a finding against the product.
- The testing claim we recorded for this product, with where it appeared: NSF Contents Certified mark printed on the label's side face. That is NSF's contents certification, a different program from NSF Certified for Sport, and the page makes no Certified for Sport claim for this package. We found no published result to check it against.
- Checked NSF Certified for Sport database on Sep 20, 2026: not listed.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. The full Certified for Sport directory read on Sep 20, 2026 carries 66 Thorne rows and no zinc bisglycinate row at all: the only Thorne zinc row is 1211643 "Thorne® Zinc Picolinate 30 mg". The label on this bottle prints NSF's Contents Certified mark, which is a different NSF program and is recorded as the maker's claim on the product, not as a listing here. Absence from a database is not a failed test.

Checked and absent. USP's own Verified Products directory was read page by page in a browser on Sep 21, 2026: 16 pages, 159 products, 16 brands, captured in this site's directory snapshot. This brand does not appear in the directory or in its brand facet, and no product in it names this brand. USP verifies the products a company submits to it, so this records which products were submitted and nothing else. Absence from a database is not a failed test.

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.
