About vitamin D

Vitamin D is an essential nutrient needed for healthy, strong bones and to help control the amount of calcium in the blood.

Recent evidence suggests that it may also help in the prevention of many other diseases and adequate levels of vitamin D are also associated with other health benefits such as immunity and cardiac function. Low levels of vitamin D have been associated with a range of diseases including osteoporosis, cardiovascular disease, multiple sclerosis and mental health issues.
