We took a look recently at the website of the Vitamin D Council, a nonprofit educational organization that advocates for wider use of this supplement, and suggests that the long-accepted dosage recommendations are too low. This is a widely discussed viewpoint, which comes following a flood of interesting research on Vitamin D in the last decade, including a great deal sponsored by the federal government. Here’s the link: http://www.vitamindcouncil.org/
Some of the website’s main points:
–Vitamin D deficiency has been linked to many varieties of cancer, as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, and more.
–A recent federally-funded study found that supplementing with 1100 IU Vitamin D3 plus calcium daily yielded a substantial decrease in cancer rates among post-menopausal women. This daily dosage of D is significantly higher than the 400 IUs traditionally recommended.
–The “flu season” may actually be a “Vitamin D deficiency season,” since a decrease in sun exposure leads to a fall in the body’s Vitamin D levels. Thus one of the most effective preventives for colds and flu may be increasing Vitamin D supplementation during the winter.
–There may be significant benefit to doses of D as high as 5000 IUs daily, especially for those who have a marked deficiency. (This is perhaps one of the more controversial positions endorsed by this website.)
For more, see the NYBC entry:
Note the NYBC also stocks Jarrow’s Bone Up, a supplement that conveniently provides dosages of both D3 (1000 IU) and Calcium (1000mg) closely reflecting those used in the federally-funded study that showed a substantial reduction in cancer rates.
