A · USP Verified
Not in our vitamin B12 comparison. Its panel also prints calcium 80 mg, and the comparison takes only packages whose panel prints vitamin B12 and no other active ingredient. It is still listed here with its price and its certification records, and is not ranked against the packages on the cyanocobalamin page.

- The panel prints "Vitamin B12 (as Cyanocobalamin) 500 mcg 20,833%" per serving of 1 tablet. Micrograms of vitamin B12 are the comparison basis here and the panel prints micrograms, so 500 mcg is read off the label rather than computed; the panel names the form as cyanocobalamin. The same panel prints a second nutrient with its own amount, "Calcium 80 mg 6% (as Calcium Carbonate and Dibasic Calcium Phosphate)", which this comparison's basis does not price; it is recorded on the product as a second active. This panel prints no "Servings Per Container" line at all. What it prints is a serving of 1 tablet, and the front face prints the count, 100 tablets, so the container holds 100 servings. That is the label's own count against the label's own serving, not an estimate.

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 B12 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 B12 500 Mcg 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 Sep 26, 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.

Informed Sport: checked, not listed
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. The closest line under this brand is "Nature Made B-Complex", which is a different product: a B-complex, not a single-nutrient vitamin B12 package. Absence from a list is not a failed test: Informed Choice certifies the products a company submits, so this records only that this product is not in the program's published list on that date.
