Printed on this bottle's own panel image as "Vitamin B12 (as Methylcobalamin) 1,000 mcg 41,667%" in a "Serving Size: One Capsule" serving. The panel names one nutrient and no other active ingredient. The panel image carries no servings-per-container line; the page's ingredient block prints "Servings Per Container: 90" and the front face prints "90 CAPSULES", which is the servings figure recorded here. The page carries Thorne's own "Gluten Free" verified badge, which is what the gluten free answer rests on; it makes no vegan or vegetarian claim. This SKU is B134, and its page description ends "NSF Certified for Sport(R)", which the 60-capsule SKU B125's page description does not.
Set the quantity at the retailer; this calculator does not add items to a cart. Uses the recorded unit price with no coupon or quantity discount. Tax is extra. Delivery terms apply to the contiguous US unless the policy says otherwise.
Free Ground shipping on all retail orders within the contiguous United States, with no minimum order value, from Thorne's shipping FAQ, first read August 31, 2026 and read again on September 18, 2026 with the same terms. Alaska and Hawaii are excluded: free above $300, otherwise a variable fee with a $30 minimum. Wholesale terms differ ($200 minimum, $11.95 below it) and are not what this site prices. With no threshold to clear, delivered cost within the contiguous US equals the price at any cart size.
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.
Price history
Latest recorded price: $34.00 at Thorne (direct), checked . Unchanged since we started checking on Sep 20 (27 checks).
We check each price about once a day, so this is the range we recorded, not necessarily every price there has been. It says what changed, not why, and nothing about where the price goes next.
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: NSF Certified for Sport.
Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: currently listed (1811504)
The listing prints Package Size "60, 90" and Serving Size "1 capsule". This bottle's front face prints "90 CAPSULES" and its panel prints "Serving Size: One Capsule", so 90 is this label's count on this label's serving unit and the listing names this package. This is also the SKU whose store page says "NSF Certified for Sport(R)" in its own description. One listing covers both of the bottles Thorne sells in this formula: the 60-capsule bottle is recorded separately and is certified at its own package too.

From the program's own published description of its process. Source. “Not stated” means the program does not publish a clear answer. It does not mean no.
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.
Thorne 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.
Thorne 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, Vegan status.
Absence of data is not evidence that a product is clean. It means nobody has published a result we could find.

Vitamin B12: 1,000mcg as labeled
Printed on this bottle's own panel image as "Vitamin B12 (as Methylcobalamin) 1,000 mcg 41,667%" in a "Serving Size: One Capsule" serving. The panel names one nutrient and no other active ingredient. The panel image carries no servings-per-container line; the page's ingredient block prints "Servings Per Container: 90" and the front face prints "90 CAPSULES", which is the servings figure recorded here. The page carries Thorne's own "Gluten Free" verified badge, which is what the gluten free answer rests on; it makes no vegan or vegetarian claim.

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. Found an error? Tell us. The full method: How we compare.
