Vitamin D is known to contribute to the protection of cells from oxidative stress, bone health and a healthy immune system. Although vitamin D has been shown to be important for bones and a normal immune system, adequate vitamin D intake has also been linked to the prevention and control of several diseases, including cancer, depression and weight gain. Vitamin D deficiency is a widespread problem in the world, but it can be easily solved by using a dietary supplement containing raw materials from natural and organic sources of vitamin D from nature.
