Upper intake level
Adults, 4,000 IU a day, from food and supplements together. One serving of this product holds 5,000 IU, more 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. A health care provider might recommend more than this for a period of time, for example to treat a vitamin D deficiency. It is not a recommendation about what to take.

In whole units
1 capsule = 5,000 IU for $0.333
This is the smallest whole number of capsules that holds at least one comparison dose. It is shown as a caveat and is deliberately not used in ranking, because rounding up changes the amount as well as the price.
- 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.

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.
NSF Certified for Sport: currently listed (1221010)
The listing prints Package Size "60, 120" and Serving Size "1 capsule". This bottle's front face prints "60 CAPSULES" and its panel prints "Serving Size: One Capsule", so the listing's bare count is this label's count on this label's serving unit, and it names the package sold. The listing's own label image carries the same amount, 125 mcg (5,000 IU) a capsule. The 120-capsule bottle, priced separately here, is the other count on the same listing.

USP Verified: checked, not listed
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.
