3. Vitamin Deficiencies
If you are dealing with the onset of vertical ridges appearing on your nails, then it could be a sign of a vitamin deficiency. Our bodies require micro-nutrients to assist in regulating metabolism. When we don’t get the vitamins our body needs, we start to develop deficiencies that can lead to a variety of adverse health issues.
If you aren’t getting enough protein in your diet, then you lack the necessary raw materials the body needs to generate new skin and hair cells, which are the building blocks of your nails. As a result, you might find that you start to develop vertical ridges on your nails. It’s more common for the ridging to occur on your fingernails first before it begins on your toes.
There are plenty of other micronutrient deficiencies that may also contribute to the development of ridging in the mails. Deficiencies in minerals and vitamins like calcium, Vitamin K, A, and zinc are also possible causes of vertical ridging in your nails.
