Also contains Vitamin K2 (MK-7) 180mcg. The price per dose counts vitamin D3 only.
Amount per serving
5,000 IU vitamin D3
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. This upper intake level is for vitamin D3 only. It does not cover vitamin K2 (MK-7) 180mcg, which the label also prints.
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 fewest whole capsules that hold at least one comparison dose (1,000 IU vitamin D3). It is shown for information only. Rankings do not use it, because rounding up changes the amount you get 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 in the store's own ingredient amounts as "Vitamin D (as Cholecalciferol) (D3) 125mcg" per 1-capsule serving, and on the Supplement Facts image NSF files for this product as "125 mcg (5,000 IU)"; the bottle front prints "5,000 IU D3". The arithmetic agrees: 1 mcg = 40 IU, so 125 x 40 = 5000 IU. Servings per container 60, from the store's block and the front's "60 CAPSULES".

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: $30.00 at Thorne (direct), checked . Unchanged since we started checking on Nov 4 (12 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 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 (1838056)
Listing 1838056, brand "Thorne®", read on Nov 4, 2026, prints Product Form Capsule, Package Size "60" and Serving Size "1 capsule", and the label image it files prints "Serving Size: One Capsule", D3 125 mcg (5,000 IU) and K2 as MK-7 180 mcg. This bottle's front prints "60 CAPSULES" and the store's ingredient amounts print the same serving and amounts, so the listing's bare count is this label's count on this label's serving unit, and the listing names this package.

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.
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.
Thorne is not on the October 2026 Informed Choice product list, which we read on Oct 3, 2026. The list, published by LGC, has 201 brands and 853 product lines. Not being listed is not a failed test. Informed Choice certifies what a company submits, so this means only that no product from this brand was on the published list that day.

Packages in the same category and format, with the same ingredients. Where we recorded the ingredient forms from the label, only packages with the same forms are shown. Where a category is compared by strength, they also have the same labeled strength. Only current prices are shown, cheapest container first. Prices are before delivery. Formulas, flavors and allergens may differ: check each label. These are browsing options, not recommended substitutes.
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.
