What deficiancy causes white spots in nails?

White spots on nails, also known as leukonychia, can be caused by several factors, including nutrient deficiencies. One specific deficiency that is often associated with white spots on nails is zinc deficiency.

Zinc is an essential mineral involved in various bodily functions, including protein synthesis, wound healing, and immune system function. When there is a deficiency in zinc, it can impact the growth and health of nails, leading to the development of white spots.

Insufficient zinc intake can occur due to certain medical conditions, such as Crohn's disease, sickle cell anemia, or chronic liver disease, which affect nutrient absorption. Dietary factors can also contribute to zinc deficiency, especially in individuals who have a limited or restrictive diet or follow strict vegan or vegetarian diets without proper supplementation.
