Ordered by price, lowest first, and labeled so you can see what each link earns us. Commission is never an input to that ordering. If the cheapest retailer pays us nothing, that is still the one we send you to. No link on this page earns us anything; every Buy button is a plain retailer link.
Verification, Tier D: Could not locate independent data
We could not locate independent testing or certification for this product. That is a statement about our search, not about the product. These programs certify what a company submits to them, so a product can be absent simply because it was never entered, which is not a finding against it. Which certifier databases we searched, and when, is listed below. Where a program is not listed there, we have not checked it and do not imply anything either way.
Searched 4 certifier databases and found no listing for this product, and located no published test results. Programs we did not search are named below as not checked.
The testing claim we recorded for this product, with where it appeared: "Ingredients must pass our 3rd party lab tests to ensure a product that is safe, pure, and potent." (sentence in the product page's own description, read Sep 20, 2026; it names no laboratory and no program). With no program named there is no listing to open against it, so it does not raise the verification level.
Checked NSF Certified for Sport database on Sep 20, 2026: not listed.
Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
The full Certified for Sport directory read of Sep 20, 2026 (2,520 listings) holds no row under Micro Ingredients, for this category or any other. Absence from a database is not a failed test.
Checked and absent. USP's own Verified Products directory was read page by page in a browser on Sep 21, 2026: 16 pages, 159 products, 16 brands, captured in this site's directory snapshot. This brand does not appear in the directory or in its brand facet, and no product in it names this brand. 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.
Micro Ingredients 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.
Micro Ingredients does not appear as a brand in LGC's own Informed Choice product list of 200 brands and 851 product lines, headed "September-2026", read in full on Sep 24, 2026. Absence from a list is not a failed test: Informed Choice 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.
Not established: Heavy-metal testing, Label-accuracy testing.
Absence of data is not evidence that a product is clean. It means nobody has published a result we could find.

1 softgel
Active ingredient
Vitamin D3 (cholecalciferol): 50mcg as labeled
Printed as "50 mcg (2,000 IU)" per softgel on this package's own panel, "Servings Per Container 500". 1 mcg = 40 IU, so the two figures agree; nothing is derived. The panel names the nutrient "Vitamin D (as cholecalciferol) (D3)"; cholecalciferol is D3. The softgel shell is gelatin, so the product is neither vegan nor vegetarian.

contains tree nuts (coconut), free of soy, free of milk
Same category and format and, for vitamin D, the same labeled strength. Different recorded ingredient-form lists are kept separate. Ordered by container price before delivery; only fresh recorded prices are shown. Formulas, flavors and allergens may differ: check each label. These are browsing options, not recommended substitutes.
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.
