Clinical experience indicates that in a high percentage of patients with white dots or lines in their fingernails (not the half moons at the base of the nail), zinc can help clear up the dots or lines within about 3 months. After a significant cold or illness, or for kids who are rapidly growing, the white dots/lines will pop up shortly thereafter.
I have found that in my patients, after zinc supplementation for a couple of months, the white dots/lines are generally gone. I also have found that there is a strong correlation between white dots/lines on fingernails and the little raised bumps that appear on the back of my patients’ arms. In this case, I often recommend zinc and omega-3 essential fatty acids. This results in either resolution or significant improvement of the problem.
Another common observation with nails are vertical ridges. I often find this is related to a lack of digestive enzymes, especially low stomach acid. Manipulation of the diet with enzyme supplementation often helps.
The bottom line? Our bodies are trying to give us clues as to what they may require in terms of nutrients. When we figure out the clues, the results can often be remarkably amazing.
