- Let’s start with Vitamins: Biotin
Biotin (also known as vitamin H and vitamin B-7) is one of the B vitamins. Since it is water-soluble, it isn’t stored by the body. Thus, you need to take it daily.
It not only helps strengthen your nails, but also helps the body’s nervous system to function better (well, we all need THAT!).
Find it in food: sardines, eggs
Take it as a pill: Vitamin B
