Have been using since having a baby almost 5 months ago... These seem to be working alright. But as with any vitamin, the results do no happen overnight and it takes time to see real progress. These are affordably priced.

I started taking biotin in order to grow out my nails. They were extremely dry and brittle and would snap off once they out grew my nail bed. In about two weeks, I noticed results. My nails grew way quicker and were strong. The only downside was that my toenails grew too and were tough to cut through.
