I bought about 4 of these containers. Unfortunately, if I had known that one pill contains 10 times less vitamin than the equivalent ones on the market, I wouldn't have bought it (it contains 100μg, while the usual ones on the market contain 1000μg). At least the quantity of vitamin contained in the pill should be mentioned in the product description title. Otherwise, it is not easy to let it dissolve in the mouth as all the other B12 pill manufacturing companies suggest, whose pills usually have a neutral or sweet taste, as this particular pill tastes like burnt paper. Finally, I hope the company that supplies them and is based in Slovakia (;!;!) will send me the receipt of payment (and not leave me with the promise that I will receive it in the future) and I hope in the future they will send it together with the product to anyone who purchases anything.
