Is Nature Made vitamin D3 USP Verified?

Our picks, by labeled strength, with a link to buy them: see where to buy. A strength with nothing certified at it has no pick, and is not listed there.

Partly: 12 of the 14 Nature Made vitamin D3 packages we track, not all of them. USP's directory names a product and a strength, not a package, and USP says the mark on the label is how a buyer knows. So a package counts as USP Verified here only when both hold: the product is in USP's directory, which we read in full, and this package's own label prints the USP Verified Mark. Every row below was read against that directory, and the row it matches is quoted.

What the directory says

USP's Verified Products directory carries 6 rows matching products in this table, each quoted above beside the package it was read against. USP publishes no page for a single product and no listing ID, so the row itself is the record, and each product page names the day the directory was read.

2 products here had no row in USP's directory on the day it was read. A directory row is one of the two things this site needs before it calls a package USP Verified, and the card below says what each label prints. Absence from a directory is not a failed test.

What each product page shows

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.

Checked and absent. USP's own Verified Products directory was read page by page in a browser on Sep 21, 2026: 159 products, 16 brands, captured in this site's directory snapshot. Nature Made is in that directory with 98 rows, and none of them names this product: its 5000 IU rows are "Nature Made Vitamin D3 Extra Strength 5000 IU (125 Mcg) Softgels" and "Nature Made Vitamin D3 Extra Strength 5000 IU (125 mcg) Gummies", and no row names a fast dissolve tablet. This package's own label prints no USP Verified Mark. 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.

Every Nature Made product we track, across all categories: Is Nature Made third party tested?

Where to buy: the picks, by labeled strength

The pick is the cheapest certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows.
