Thorne Vitamin D-5,000, NSF Certified for Sport (60 capsules)
Label read Sep 20, 2026. Where the data comes from
Is Thorne vitamin D NSF certified? · Is Thorne third party tested? · Which vitamin D3 brands are third-party tested?
Cost
- One capsule holds 5,000 IU of vitamin D3, 5 times the 1,000 IU comparison dose. Capsules cannot be split.
- Printed on this package's own panel as "Vitamin D (as Vitamin D3) (5,000 IU) 125 mcg". The label states the IU figure itself, and the arithmetic agrees: 1 mcg = 40 IU, so 125 x 40 = 5000 IU, which the panel writes as 5,000 IU. 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.

Set the quantity at the retailer; this calculator does not add items to a cart. Uses the recorded unit price with no coupon or quantity discount. Tax is extra. Delivery terms apply to the contiguous US unless the policy says otherwise.
Delivery terms and limits
Free Ground shipping on all retail orders within the contiguous United States, with no minimum order value, from Thorne's shipping FAQ, first read August 31, 2026 and read again on September 18, 2026 with the same terms. Alaska and Hawaii are excluded: free above $300, otherwise a variable fee with a $30 minimum. Wholesale terms differ ($200 minimum, $11.95 below it) and are not what this site prices. With no threshold to clear, delivered cost within the contiguous US equals the price at any cart size.
Where to buy
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 cheapest retailer 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: $20.00 at Thorne (direct), checked . Unchanged since we started checking on Sep 20 (27 checks).

Verification, Tier A: Independently certified
This exact package is inside the certifier’s own scope: named on an NSF Certified for Sport listing, or, for USP Verified, the product is in USP’s directory and its mark is on this package’s label. Both audit the manufacturing site and both confirm the label’s own claims against the finished product. They are not interchangeable beyond that: NSF Certified for Sport also screens for substances banned in sport, and USP Verified does not. USP instead checks that the product dissolves and releases within a specified time. What each program checks is set out per program below.
- Current listing found: NSF Certified for Sport.
- Checked USP Verified database on Sep 21, 2026: not listed.

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.
