Biotin is a really good vitamin to help with many functions in the body and for hair care it is absoluetly essential too. I try to have an extra supply of these vitamin/mineral on hand if possible. This one is super potency which means it probably has more than enough in it, which you want to be careful of too that you don't take too much. Some viatmins are dangerous in large amounts. These are softgels so they are easy to swallow. Nature's Bounty is also very well known and that is what you want to look for in a vitamin supplement too to help insure quality and safety.
