Although it is a good and cheap supplement, it has side effects. My wife tried it and it irritated her chest, and even though I didn't ingest it, it bothered my stomach! Figure it out!

It does the job of hematological tests, it is Greek, it is cheap, and it melts in the mouth with a nice taste.

I had a B12 deficiency (68) and after initially taking it for 3 months (double dose), it raised my vitamin levels to very good levels (320). Now I continue to take 1 tablet daily for maintenance. It dissolves in the mouth and has a nice taste.

I did not take measurements before and after, so I do not have an opinion on whether it really works. I bought it as a precaution due to intense training during the second half of marathon preparation. As for the sensation, I can't say that I felt anything (before the best). If I didn't take it at all, I can't know if I would feel the same, worse, or even better (why not?). What I liked and left a very good impression was its very nice taste! You really drink it very pleasantly!

I have been taking it for a month now, I don't have an opinion on whether it does its job, I haven't done any tests yet to see if my B12 levels have increased, it has a nice taste and it is easy to take.

Unfortunately, it caused me skin problems. I wouldn't buy it again. I tried several pills to make sure that this product caused the problem, in the end, I threw away the whole box!

It looks very similar to the D3 from the same company. Very pleasant taste while dissolving in the mouth. The difference in energy levels was not huge, but it remains a very good choice (having tried two other brands)
