Someone told me that biotin is very good for your hair and nails. Is this true? How much should I be taking? What exactly are the benefits of taking it?
Karen :)

This is true. Biotin also helps for clearing up the skin. I stopped taking it a long time ago because it seemed to have stopped working for me. I suppose I became "immune." I will begin taking it again soon though. Give it a shot! I don't remember what dosage I took... I don't think there's too many varying dosages.
