Why do i have weak nails? related to diet?

A doctor has provided 1 answer

Diet and disease : Brittle weak nails can be caused by deficiency in iron, biotin, zinc, silica, calcium, vitamin c, thyroid, estrogen, and magnesium. You can see it might be good to see your doctor to check out. It is a good thing to have this external sign of deficiency. You can get better.
