The vitamins I use are:
Natures Bounty Hair, Skin and Nails: This has 3000mcg of Biotin in it.
Flaxseed Oil
Vitamin E
Calcium
I also have a protein shake for breakfast and a protein bar in the afternoon as my snack.
I use baking soda as a clarifier as Fox has stated. I find that it does a fantastic job and is inexpensive too!
Hope this helps!

"There are times when only a dog will do for a friend: when you're beaten, sick and blue, and the world's all wrong; for he won't care. If you break and cry, or grouch and swear; for he'll let you know as he licks your hands that he's downright sorry and understands." -Don Blanding (1894-1957)
