What Are The Triggers Of Vertical Split Nails? 15 Common Causes

Biotin Deficiency

Biotin is a water-soluble vitamin that’s part of the B vitamin family. Like other B vitamins, biotin plays an important role in energy metabolism. It’s also involved in the synthesis of fatty acids, glucose, and some amino acids. Biotin is found in many foods, including egg yolks, nuts, seeds, legumes, and leafy green vegetables. It’s also available in supplement form. Most people get enough biotin from their diet or the bacteria in their gut. 

Biotin is necessary for the growth of healthy nails and hair. A biotin deficiency can cause brittle nails prone to splitting and peeling. In severe cases, biotin deficiency can also lead to total hair loss. 

While vertical splits in the nails may be the first sign of a biotin deficiency, it’s important to note that other things can also cause this condition. For individuals who suspect their vertical split nails are caused by biotin deficiency, it is imperative to schedule an appointment with a doctor. They will likely order a blood test to confirm the diagnosis and provide the best treatment options.
