Not enough vitamin D: health consequences for Canadians. Schwalfenberg G. Can Fam Physician. 2007 May;53(5):841-54. Review PMID: 17872747 Conclusion Low levels of VTD are considered a major public health problem in Canada, especially during the winter. Those with risk factors should be screened for low 25(OH)D levels and repletion therapy instituted if needed. Researchers have estimated that the oral dose of vitamin D3 to attain and maintain 25(OH)D levels >80 nmol/L is 2200 IU/d if baseline levels are 20 to 40 nmol/L, 1800 IU/d if levels are 40 to 60 nmol/L, and 1160 IU/d if levels are between 60 and 80 nmol/L.64 We need to ensure that patients have healthy blood levels of 25(OH)D to prevent levels of parathyroid hormone from rising and to maximize absorption of calcium, magnesium, and phosphate. Positive effects on bone are marginal at best unless patients consume at least 800 IU/d of VTD. The emerging and exciting role of the VTD receptor and the actions of VTD in maintaining health in other cell types have become more apparent during the last decade.

Safety of vitamin D3 in adults with multiple sclerosis. Kimball SM, Ursell MR, O'Connor P, Vieth R. Am J Clin Nutr. 2007 Sep;86(3):645-51. PMID: 17823429 Conclusions: Patients' serum 25(OH)D concentrations reached twice the top of the physiologic range without eliciting hypercalcemia or hypercalciuria. The data support the feasibility of pharmacologic doses of vitamin D3 for clinical research, and they provide objective evidence that vitamin D intake beyond the current upper limit is safe by a large margin.

A Track Your Plaque member brough the following webcast to our attention: Prospects for Vitamin D Nutrition\nwhich can be found at http://tinyurl.com/f93vl (The above link no longer seems to work, use http://wildhorse.insinc.com/directms13oct2005/ instead) Despite the painfully dull title, the webcast is the best summary of data on the health benefits on vitamin D that I've seen. The presenter is Dr. Reinhold Vieth, who is among the handful of worldwide authorities on vitamin D. In 1999, Dr. Vieth authored the first review to concisely and persuasively argue that vitamin D nutrition was woefully neglected and that its potential for health was enormous.

If you've been following the Track Your Plaque conversation, you know that, contrary to prevailing opinion among many cardiologists, there is an emerging notion that coronary calcification is an active process, a true part of the disease. Vitamin D3 is an important aspect of this question. So is vitamin K2. Not to be confused with K1 that plays a role in blood coagulation, K2 has an important role in calcium metabolism. Thus, vitmain K2 deficiency is related to osteoporosis and to coronary calcification.

Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.
