Biotin is available at Walmart. It is a common B vitamin.
It might be better to get a B complex from any store. However, due to issues some have folic acid building up and with converting normal B vitamins into active forms in the body, a B complex with active forms of B vitamins is a better B complex choice, despite the higher cost of active B vitamin forms.
Consider Jarrow’s “B Right” or Douglas Laboratories “B Complex,” which have the active forms of multiple B vitamins with normal biotin. If someone is low in biotin, they are probably low in other B vitamins, which, aside from the folic acid form of folate, cannot build up in our bodies for much longer than a day (the folic acid form of folate can build up for weeks if having too much).
interesting. thanks. much of the interest of late has been on the b3 and its variants. I like your advice to get the b complex vitamin and your suggestion as to the brands that do the best job. On thing that was not clear to me from the article was the dosage. Is there advantage to taking more than whatever is the recommended dose? (the recommended dose would come with the multivitamins.) Do you get more protection with higher dosages? How do you read that?
