Another vitamin D update

Epub ahead of printHollis BW. Short-term and long-term consequences and concerns regarding valid assessment of vitamin D deficiency: comparison of recent food supplementation and clinical guidance reports. Curr Opin Clin Nutr Metab Care. 2011 Sep 19.

Purpose of review: The function and use of vitamin D supplementation has become very controversial. This review attempts to provide a balanced perspective with respect to the experimental findings published in the past 18 months.

Recent findings: The recent contrasts between the Institute of Medicine (IOM) report and the Endocrine Societies report have caused great confusion with respect to the dietary requirement for vitamin D as well as the amount of circulating 25-hydroxyvitamin D that is desirable. Much recent data contradict the suggestions of the IOM report with respect to vitamin D's role in chronic disease such as cancer, cardiovascular function, immune function and autoimmune ailments such as multiple sclerosis.
Summary: Controversy regarding supplementation with vitamin D is fueled by the different purposes of the IOM (guidance for food fortification and not to individualized patient care) and the Endocrine Societies (patient care) reports. Healthcare providers should formulate their own opinions with respect to vitamin D as it pertains to the care of their patient.

"Bruce Hollis the vitamin D sage has obviously written this review to address the discordant advice regarding levels of vitamin D supplementation for food fortification (public health) and clinicians (patient care). The bottom line is you need to be vitamin D replete and in the UK this requires a daily requirement of ~10,000U per day over the year (5,000 from diet and sunshine and 5,000 from supplements)."

"If you are new to this blog please check-out some of the previous posts on this blog that relate to vitamin D in MS. It is clear that this is a big issue for MS'ers."
