What causes toenails to crumble?

Answer by  HawaiianGirl (6906)

If your toenails crumble it could be because a lack of proper nutrition. Another reason could be that you have a toe or foot fungus which causes the thick nail as well as causing it to crumble.

It seems your nails are not strong and are weakening. Weakening of the nails is normally a sign that your body is lacking B vitamins. Increasing your B vitamin intake should help your nails get stronger.
