Nutricology B12 Adenosylcobalamin Vegetarian Lozenges, 60 Count

I've always struggled with low B12, but after taking this brand for 2 months, I'm in the normal range for the first time. It's a hard pill that you put under your tongue. It doesn't really dissolve, but clearly it works.

The best and most readily used B12 for quick absorption. This sublingual tablet skips the cyanide conversion step as found in cyanocobalamin.

No difference taking it.

Worst didnt made any effect ....

In buying some vitamins prescribed for an elder relative of mine I was extremely displeased finding that these vitamins have printed on the bottle "Formulated exclusively for Nutricology" (see attached image), indicating they are distributed by Nutricology but manufactured by someone else despite carrying the name of the company as a brand. The company is just a distributor and seller of third-party products, some of which are imported from abroad.At the time of this writing, their third-party origin is not disclosed here nor in this vitamin's page of the company's website. Such a lack of transparency extends to images: the printed statement is cropped out in the only image of the corresponding side of the bottle among those at the top of this page, and the statement cannot be read in the image shown in the company website for this or other products they sell. You need to keep exploring other, non-product pages of their website to find they are not a manufacturer.So what is the importance of that? Well, since the name of the actual manufacturer of this product is not disclosed, educated consumers cannot inform themselves about the place of origin, the manufacturer's reputation, or the manufacturing standards it observes, and whether or not is a member of an accredited group. Thus the sole guidance on quality would rest on the claims-without-proof of Nutricology, such as "All of our certified manufacturers meet or exceed cGMP requirements established by the FDA, as well as state and local regulations." Alas, the nature of what is being certified and by whom is completely left to one's imagination, since no images of the claimed certifications are posted (something that even Chinese sellers in their huge online marketplace do). And that is not enough, especially from a distributor/seller in an industry whose health claims are obliged to carry the disclaimer they have "not been evaluated by the U.S. Food and Drug administration." Nutricology is a non-BBB accredited business and part the of Allergy Research Group LLC, whose Founder, Chairman, CEO, CFO, and co-Chairman of its Medical Advisory Board (with no actual MDs) is married to the co-Founder, Vice President, Secretary and Director.Though not labeled as a sublingual product, the Nutricology's recommendation of placing the lozenges "under the tongue 30 seconds before swallowing" may leave some customers with the idea the tablets are designed for sublingual absorption. They are not. True sublingual tablets have to remain beneath the tongue until they dissolve, as opposed to be swallowed 30 seconds later, which is why the sublingual formulations are designed to dissolve quickly in small amounts of saliva. But these B12 lozenges only dissolve very little in 30 seconds under the tongue and most of (if not all) the dissolved cobalamine in the saliva is swallowed, as opposed to sublingually absorbed, and soon followed by the undissolved major part of the lozenge. At any rate, as Don Goldberg (a registered pharmacist interested in supplements) remarks in his blog: "Vitamin B12 is not absorbed sublingually. Sublingual absorption works for small molecules, not large ones, and vitamin B12 is a very large molecule." He adds that the "sublingual, or lozenge forms of vitamin B12 ... work, but only because you end up swallowing the vitamin B12 as the lozenge dissolves, allowing it to be absorbed in the gut just as if it was a normal tablet or capsule."
