Why do I have ridges in my fingernails?

I know that it has something to do with a vitamin deficiencey. But WHICH vitamin should I be adding to my diet?


Thanks.Why do I have ridges in my fingernails?
yes it's a vitamin deficiency. Vitamin c is always good and iron helps keep your nails in tact. I hope this helps. Look up ridged nails on the computer and it will tell you exactly what to do.
