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.

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 as "Vitamin D3 (as Cholecalciferol) 5000 IU 625%" per 1-capsule serving on this bottle's own Supplement Facts panel image ("Servings per Container: 60"); no mcg figure on the panel. The front prints "60 Capsules" and "D3 5000 IU / K2 100 mcg".
Delivery
Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $55.01 below the $75.00 threshold, and this retailer does not publish a rate, so we cannot tell you what it will add. Free shipping on orders of $75 or more, from the announcement bar on coremedscience.com, first read August 31, 2026 and read again on September 28, 2026 and October 17, 2026 with the same figure. The shipping policy page itself states no domestic threshold. No rate is published below $75, so delivered cost below it is Unknown and those listings are left out of cheapest-delivered claims.
Cost per dose delivered
at least $0.067
We will not put a number on this. The product price is a floor, not the price you will pay. Reaching the free-delivery threshold, or choosing a retailer that publishes its rate, is the only way to know in advance.

Latest recorded price: $19.99 at Core Med Science (direct), checked . First checked on Oct 17.

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 (1798542)
NSF listing 1798542, "Vitamin D3-5000 & K2", brand Core Med Science, read on Oct 17, 2026, prints Product Form Capsule, Package Size "60" and Serving Size "1 capsule", and the label image it files prints "Serving Size: 1 Capsule", "Servings per Container: 60", "Vitamin D3 (as Cholecalciferol) 5000 IU" and "Vitamin K2 (as Menaquinone-7) 100 mcg". The bottle priced here prints the same panel, 60 servings of 1 capsule, and "60 Capsules" on its front, so the listing names this package. The brand's 2,000 IU + K2 bottle is a separate 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.
