  • Printed on this bottle's own panel image as "Vitamin C (as Ascorbic Acid) 1 g 1,111%" in a "Serving Size: One Capsule" serving, and the front prints "Vitamin C 1,000 mg", "as Ascorbic Acid" and "60 CAPSULES". We compare milligrams, so the panel's 1 g is recorded as 1,000 mg (1 g = 1,000 mg), the figure the front prints. The panel names one nutrient and no other active. The panel image carries no servings-per-container line; the page's ingredient block prints "Servings Per Container: 60" and the front prints 60 capsules, which is the figure recorded here. The side face's GLUTEN FREE mark and the page's "Gluten Free" badge are what the gluten free answer rests on; no vegan or vegetarian claim is made.

Ordered by price, lowest first, and labeled so you can see what each link earns us. Commission is never an input to that ordering. If the retailer with the lowest current price pays us nothing, that is still the one we send you to. No link on this page earns us anything. Every Buy button is a plain retailer link.

Price history

Latest recorded price: $19.00 at Thorne (direct), checked . Unchanged since we started checking on Oct 17 (28 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 level 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.

  • Testing claim we recorded, and 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 Thorne's store page makes no Certified for Sport claim for this package. NSF’s Contents Certified listings were not searched for this product, so the claim is not checked here either way.
  • Checked NSF Certified for Sport database on Oct 17, 2026: not listed.
  • Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. The Certified for Sport directory as captured on Sep 23, 2026 carries 66 Thorne rows, filed under "Thorne" and "Thorne®", and none is a vitamin C product: no row under either name contains "vitamin c", "ascorb" or "flavonoid". 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. NSF's whole directory was read again on Oct 17, 2026, 2,581 listings, and still holds no vitamin C listing under this brand.

USP Verified: checked, not listed
Checked and absent. We read all 16 pages of USP's own Verified Products directory in a browser on Sep 21, 2026: 159 products from 16 brands. We saved a copy. This brand is not in it: not in the directory's brand filter, and not in any product name. USP verifies the products a company submits to it, so this shows only which products were submitted. Not being listed is not a failed test.

Informed Sport: checked, not listed
Thorne is not on the October 2026 Informed Sport product list, which we read on Oct 3, 2026. The list, published by LGC, has 497 brands and 1,887 product lines. Not being listed is not a failed test. Informed Sport certifies what a company submits, so this means only that no product from this brand was on the published list that day.

What this rests on: Prices are the last ones we recorded at the retailer named on each product page. Prices go stale, so each page says when it was checked. We track some products, not every one sold, and Amazon and Walmart are not among our stores. Listings and labels are read at the source, and each page links to them. Found an error? Tell us.
