Vitacost L-Cysteine -- 500 mg - 180 Capsules
Just starting using it too early to tell but trust it will since Vitacost has their own excellent brand and I have purchased and used many of them and had great success and results.

Great for fingernail strength
L-Cysteine was recommended to me because my nails peeled, split, and were very weak. After taking L-Cysteine for a while, my nails are wonderful ... no peeling, splitting, and now my problem is having to constantly trim them. Nice problem.
