The Sunshine Vitamin D3!
First, Vitamin D found itself on the cover of US News & World Report ("The Amazing Vitamin D", Dec. 18, 2006 issue, pp.65, 66). Inside was a two page article on the benefits of Vitamin D, and some of the problems people encounter when there is a deficiency. By the end of the article, it stated "that 2000IUs is a worthy goal for everybody".
Vitamin D deficiency showed up in back pain sufferers, type 2 diabetes, female infertility, osteoarthritis and osteoporosis, migraines, multiple sclerosis, Alzheimer's Disease, psoriasis, rheumatoid arthritis, tooth decay, and obesity. Interestingly, Vitamin D levels decline by up to 50% as part of the aging process.
Then on June 23rd, 2008 in the journal Archives of Internal Medicine the lead author Dr. Harald Dobnig, of the Medical University of Graz in Austria said, it's not "ultimate proof" of the harmful effects of too little vitamin D, "But the evidence is just becoming overwhelming at this point." Dr. Dobnig goes on to state, "Physicians should be aware of the widespread problem of low vitamin D status." He bases these statements on his "study showing a significant association between serum (blood) vitamin D levels and risk of all-cause and cardiovascular mortality,"
Low vitamin D levels have been linked in recent studies to an increased risk of breast, colon and endometrial cancers, and multiple sclerosis. Men with low vitamin D appear to have a higher risk of heart attacks.
Vitamin D is best known for its role in working with calcium to build strong bones. New studies indicate Vitamin D may also reduce cancer risk, prevent tooth loss, help with muscle strength (including our heart muscle), fight infection (such as the flu), prevent the progression and development of multiple sclerosis, improve lung function, protect against rheumatoid arthritis, protect against Inflammatory Bowel Disease (IBD), and the list goes on.
Vitamin D3 (cholecalciferol) is the preferred form of Vitamin D and the form made by animals. Vitamin A, magnesium and strontium compete with Vitamin D for absorption and when supplemented should be taken separately. Vitamin K2 aids absorption. Vitamin D should be taken with Calcium supplements to improve its bone building ability, and also with Boron, which is essential for the conversion of Vitamin D to its active form.
Basically, our bodies can make
vitamin D3 only when our skin is exposed to sunlight under the proper
conditions. This production is dependent on the season, where we live and time
of day. Also, people with darkly pigmented skin living in northern or southern
latitudes have lower synthesis compared to fair skin people. Plus, sunscreen
with a sun protection factor (SPF) of 8 reduces the production of vitamin D3 by
over 95%. During late autumn through winter, little or no vitamin D can be
produced by sun exposure at latitudes above 35° north, which runs through the
middle of the
