Upper intake level
Adults, 4,000 IU a day, from food and supplements together. One serving of this product holds 1,000 IU, less 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.

- The panel prints "Vitamin D3 (as Cholecalciferol) 25 mcg (1000 IU) 125%" per serving of 1 softgel. Labeled IU is the comparison basis here and the panel states it directly, so 1000 IU is read off the label rather than computed; the panel's own 25 mcg is the same amount written in the other unit. This panel prints no "Servings Per Container" line. The serving it does print is 1 softgel and the front face prints "100 SOFTGELS", so the container holds 100 servings: the label's own count against the label's own serving.

Delivery terms and limits
Free shipping within the contiguous United States on orders of $25 or more before tax, and a flat $8 fee below that, from Nature Made’s own shipping policy page read September 23, 2026: "Free shipping within the contiguous U.S. is available on: Orders $25+ (before tax)" and "A flat $8 shipping fee applies to: Orders under $25". Shipments outside the contiguous United States, including Alaska and Hawaii, carry the same $8 fee. The page calls neither term temporary. It also says some products or state requirements may add cost, shown at checkout, so a delivered total can be higher than these two figures describe.

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: USP Verified.
- Checked NSF Certified for Sport database on Sep 24, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. The full Certified for Sport directory read of Sep 24, 2026 holds one row under Nature Made, listing 1809934 "Micronized Powder Creatine Monohydrate", and no vitamin D or D3 row under this brand at all. Absence from a database is not a failed test.

USP's Verified Products directory, read in full on Sep 21, 2026, carries the row "Nature Made Vitamin D3 1000 IU (25 Mcg) Softgels", which names this product and strength and no package size; USP's directory links to the brand and its own site says the mark on the label is how a buyer knows. This package's own label prints the USP Verified Mark (read Sep 24, 2026). Both together are the test this site applies to USP: the directory row confirms the product, the mark on this label is USP's own scope. Confirmed at this package on that basis.

Nature Made does not appear as a brand in LGC's own Informed Sport product list of 496 brands and 1878 product lines, headed "September-2026", read in full on Sep 24, 2026. Absence from a list is not a failed test: Informed Sport certifies the products a company submits, so this records only that none from this brand is in the program's published list on that date.

Nature Made is on LGC's own Informed Choice product list of September 2026 with 12 product lines, read in full on Sep 24, 2026, and none of them names this product.

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.
