What's wrong with the fingernail nutrition circle gone?

The nutrition circle on the finger, commonly known as protein circle, is also called half crescent. It reminds you that your body is particularly short of protein, so you should eat more things containing protein, such as eggs, beans and lean meat. If you want to repair it quickly, you need to supplement Nutrilite protein powder. If there are many fine lines on the fingernail, it is your body reminding you of calcium deficiency. Remember to add, you can ask again if you are not clear.
