Vitamin D deficiency is a common deficiency that can lead to problems with bones and muscles. It most often affects people over the age of 65 and individuals with darker skin. This deficiency is preventable and treatable.<\/p>\n

Vitamin D is one of the fat-soluble vitamins and is also classified as a hormone. It can accumulate in the body through sunlight exposure or be obtained from food. Vitamin D is also known as calciferol. Along with several other factors, vitamin D plays a key role in regulating the metabolism of calcium and phosphates and facilitates their absorption in the intestines. Thus, it significantly supports bone mineralization and influences various hormones. Vitamin D also plays a role in muscle metabolism and immune system function.<\/p>\n
