Nail-ex is available as a tablet containing 2,500 micrograms (mcg) of biotin, a B vitamin found naturally in the body and in some foods. Biotin is essential for healthy metabolism and the proper functioning of the nervous system. It is also needed for healthy hair, skin and nails. There is some preliminary evidence that taking biotin supplements may help strengthen splitting, weak or brittle nails, but more study is needed to confirm these findings. Talk to your doctor about your biotin needs before taking Nail-ex or other biotin supplements.
