"Calcium deficiency causing white spots on nails is the most common myth, followed by zinc deficiency. The truth is that white spots are common and harmless and don't indicate any specific vitamin deficiency at all," Krant says. "Most likely they are signs of previous trauma to the nail plate (the hard part of the nail) or the matrix (the source of the nail plate, which is located underneath the cuticle under the skin). Just like folding or denting a piece of clear plastic leaves a white spot, so does pressure or trauma to the nail." - Huff Post
