U.K. and Canadian scientists have found vitamin D to be even more so vital to health and well being than previously thought. Their new findings have revealed vitamin D as a direct influencer of more than 200 human genes. One such gene is related to both cancer and autoimmune diseases such as multiple sclerosis. According to scientists, vitamin D deficiency makes us susceptible to a wide host of diseases. Other diseases thought to be influenced by vitamin D deficiencies include rheumatoid arthritis, type 1 diabetes as well as dementia. Vitamin D is naturally produced in the body as a result of direct sun exposure to the skin. Vitamin D is also present in larger amounts in fish oils – a common source for most vitamin D supplements. It’s important to note that in larger quantities, vitamin D is also toxic. A number of experts recommend daily dosages of vitamin D ranging from 25 to 50 micrograms.
