If You Have White Marks On Your Fingernails You Should Read This
Don’t worry, you aren’t going to die but you possibly have a medical condition called “Leukonychia” I have this condition too, in case any of you were wondering.
Some say leukonychia is a sign of excess or deficiency of calcium, zinc, or other vitamins in the diet, while others say it isn’t. Check out this article from health.howstuffworks.com. There is a ton of info and a lot of links for further reading and studies that have been carried out. Either way, I think it’s cool that something so small could have such a scary medical name.
