Take biotin supplements
In several studies, researchers found that supplements of biotin (a member of the vitamin B family) increased nail thickness and prevented splitting and breaking. In a respected German study that evaluated 45 people with severe nail problems, 2.5 milligrams of biotin daily for several months benefited everyone with 91% of the 45 citing significant improvement. NYU dermatologist Sumayah Jamal, MD, says to get the effect, it s vital that you take the prescription strength, therapeutic level of 2.5 milligrams daily.
Some nail products also contain silicon and the supplement MSM, two other nutrients associated with nail health.
