Vitamin D – Vitamin D is a fat-soluble vitamin that’s important for immune function, bone and muscle health, brain and mental health, and other areas of your health. Vitamin D deficiency may play a role in autoimmunity. 85 percent of people have insufficient levels of vitamin D and are unaware of their deficient state. According to one large-scale study, optimal vitamin D levels can slash your risk of cancer by as much as 60 percent. Vitamin D can also help reduce the risk of other conditions as well, including type 2 diabetes, chronic inflammation, age-related macular degeneration (the leading cause of blindness), and Alzheimer’s disease. Vitamin D also exhibits its infection-fighting abilities in the treatment of tuberculosis, pneumonia, colds, and flu. It can also improve seizure control in epileptics. While scientists refer to vitamin D as a vitamin, it is actually a steroid hormone obtained from sun exposure, food sources, and supplementation.
