    My! nails! are! so! much! stronger! I can't believe this. Even after undoing gel nail polish, they are so much stronger than before. My hair is also benefiting from these; it does not seem as thin as before (this could be a benefit of changing shampoos as well, but I think these pills are helping). Would recommend!

    I have never been able to grow my nails. They have been thin and break easily until I found this supplement. After a month of use, my nails are long, thick and healthy. I also noticed my hair is growing and feeling better as well. Great supplement!

    I had a gel manicure that finally wrecked my nails-I’ve never had problems with peeling or splitting nails before so I had no idea how to fix. I started taking these and within two weeks my nails stopped splitting, and within the month they were hard again. Like, so hard it felt like there was a gel manicure on them keeping them in place. An added bonus is that I think my hair also grew!

    Nails were strong again within two weeks. I also felt that my hair was looking stronger as there was less hair on my hair brush everyday. I recommend these for those who are looking for stronger nails that won’t break! There were a couple instances where I thought for sure my nail broke but when I looked, it was still there! Couldn’t believe it!

    I’m on my second month and I think it’s helping. I’ve got one nail that constantly cracks and splits, and it’s only happened once since I’ve started the supplement. I’d like to give it another month or two, as this formulation seems unique in the market.
