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. A program not named below was not checked for this product.
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
Checked and absent. The full Certified for Sport directory was read on Sep 20, 2026 and carries 2,520 listings. No listing in it is filed under this brand, and the five listings in the whole directory whose product or brand name matches "b12", "b-12" or "cobalamin" belong to Herbaland Naturals, Pure Power, TB12(R) PROTEIN and Thorne. The label on this package prints no NSF mark. 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.
Havasu Nutrition 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.
Havasu Nutrition 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.
No laboratory report with figures is recorded here for this product.
Not established: Heavy-metal testing, Label-accuracy testing.
Absence of data is not evidence that a product is clean. It means we found no published result for that testing.

Active ingredient
Vitamin B12: 720mcg as labeled
Printed on this bottle's own panel as "Vitamin B12 (as Methylcobalamin) 720 mcg 30,000%" in a "Serving Size: 1 Dropper (1 mL)" serving, with "Servings Per Container: About 30", recorded as 30. The comparison basis is micrograms of vitamin B12 and the panel prints micrograms, so nothing is converted, and the panel names one nutrient and no other active ingredient. The serving unit is the panel's own dropper. The carton prints "1 fl oz (30 mL)", a volume, so no net weight is recorded, and 30 servings of 1 mL agrees with it. The label's VEGAN and GLUTEN FREE seals are what the vegan and gluten free answers rest on; its organic certification and cGMP seal are not testing programs, so no third-party testing claim is recorded.
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.
