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 softgel = 5,000 IU for $0.068
This is the smallest whole number of softgels 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 softgel holds 5,000 IU of vitamin D3, 5 times the 1,000 IU comparison dose. Softgels cannot be split.
- Printed as 125 mcg per serving; the label also gives 5,000 IU. 1 mcg = 40 IU, so the two agree (125 x 40 = 5,000).
Delivery
Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $34.03 below the $59.00 threshold, and this retailer does not publish a rate, so we cannot tell you what it will add. Free delivery on orders over $59 within the contiguous US. Below that, the rate is calculated at checkout and is not published in advance. Alaska, Hawaii and Puerto Rico may incur extra charges by weight.
Cost per dose delivered
at least $0.014
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.

Verification, Tier A?: Independently certified, package unconfirmed
A certification program lists this product, but its listing does not name the package size priced here, so we do not present it as an unqualified certification. The listing, and exactly what it does and does not cover, is set out below.
- NSF Certified for Sport lists this product, but the listing does not cover the package size shown here. Same product line as NSF listing 1823428, but that listing names only the 500-count package. This 365-count bottle is not named, so under the strict scope policy the certification does not cover it. The 500-count is the certified one.

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.
