I have a couple white spots on my fingernails.

Q. Dear Terry, “I have a couple white spots on my fingernails. My friend told me it could mean I don’t get enough zinc. I’m interested in trying zinc to see if it makes any difference in my nails. How much zinc should I take per day?” – Geneva P., Woodbury, MN

A. Dear Geneva, There are many conditions that can impact the health of our nails like trauma, infections, and nutrient deficiencies. Zinc is an essential nutrient when it comes to the health of hair, skin, and nails. Research has shown that zinc deficiency can cause nail dystrophy, which makes the nails rough, thin, and brittle.

Zinc works synergistically with another mineral, selenium. Selenium deficiencies have also been implicated in various nail conditions. Selenium is crucial for an enzyme in the body that produces glutathione. Glutathione has been called the “master antioxidant”. Increasing antioxidants in the body may help improve nail conditions.

Because zinc can be hard to absorb, I prefer zinc that is chelated, which means bound to the amino acid glycine. This form of zinc is also called zinc glycinate. I would take 30 mg of zinc per day and 200 mcg of selenium. These minerals are very safe and can be taken daily.

Healthy Regards!
