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: USP Verified.
- Checked NSF Certified for Sport database on Oct 17, 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 C row under this brand at all. Absence from a database is not a failed test. NSF's whole directory was read again on Oct 17, 2026, 2,581 listings, and still holds no vitamin C listing under this brand.

USP's Verified Products directory, read in full on Sep 21, 2026, carries the row "Nature Made Chewable Vitamin C 500 Mg Tablets", 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 Oct 17, 2026). We count a USP product as confirmed at a package only when both are true: USP's directory lists the product, and that package's label carries the USP mark. Both are true here, so this package is confirmed.

Informed Sport: checked, not listed
Nature Made 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.

Vitamin C: 500mg as labeled
The panel prints "Vitamin C (as Sodium Ascorbate and Ascorbic Acid) 500 mg 556%" per serving of 1 tablet. We compare milligrams of vitamin C, and this label prints milligrams, so we used its 500 mg as printed, with no conversion. The label names the form as sodium ascorbate and ascorbic acid. The calorie, carbohydrate, sugar and sodium lines the panel also prints are nutrition facts rather than a second active, and nothing is priced on them; citrus bioflavonoids appear in the other ingredients with no amount. This panel prints no "Servings Per Container" line. The serving it does print is 1 tablet and the front face prints "150 TABLETS", so the container holds 150 servings: the label's own count against the label's own serving.
