What does it mean if you have very white nails on fingers and toes?

Instead of the usual slight pinkish tinge they usually are? Mine are very white and also I have no half moons on my finger nails? Does it mean anything? I am not worried, just interested to know. It may mean nothing. Thanks very much.What does it mean if you have very white nails on fingers and toes?

not enough zinc in your daily intake. try taking a multivitamin or a zinc supplement.
the white on the nails means you aren't getting enough oxygen...as for the little moons, i'm not sure.
