Micronutrients (vitamins and minerals) have key roles in numerous homeostatic processes, enabling the body to produce enzymes, hormones and other substances that are essential for energy production, cell maintenance and repair, immune function and recovery from illness, blood formation, and maintenance of vital organs.

Vitamin D functions as a hormone in the body. One study explains that both vitamin D and estrogen work together to reduce the risk of cardiovascular disease. The link between these hormones is due to the role that vitamin D plays in estrogen synthesis.

Vitamins are substances that your body needs to grow and develop normally. Vitamin D helps your body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets. Vitamin D also has a role in your nerve, muscle, and immune systems.

Vitamin D sufficiency prevents rickets in children and osteomalacia in adults [1]. Together with calcium, vitamin D also helps protect older adults from osteoporosis. Vitamin D has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation [1,3,4].
