Vitamin D Recommendation Ten Times Too Low | Lifestyle Chiropractic

vitamin-dVitamin D Recommended Daily Allowance

I remember in 2005 sitting in a nutrition seminar on the vital importance of optimizing Vitamin D levels in our bodies.  The doctor speaking – who had many letters separated by commas after his name – cited ongoing research in this area and said that most everyone should be supplementing this vitamin.

He also said – with his tongue in his cheek –  that the RDA (Recommended Daily Allowance) should actually be referred to as “Really Dumb Advice” in this case!

The reason is that the RDA was developed with the goal of reducing the incidence of rickets – a formerly common illness – and so for years the recommended amount was 400 IU of Vitamin D per day.  However, this was too narrow a focus given developing research and so over the past 10 years we have seen the RDA increase to the current recommendation of 600 IU per day and 800 IU per day in older adults.

Well, many say that is still not enough.

In fact, there is evidence suggesting that the current recommendations depended on faulty statistics and the actual amount needed may be 10 times higher!

In a letter published recently in Nutrients, Paul Veugelers and John Ekwaru of the
School of Public Health at the  University of Alberta point to a statistical error made in the initial calculation of the RDA for vitamin D. They show that to raise blood levels of vitamin D to the level desired, an amount of 8895 IU vitamin D per day is what is actually required!

For many of us, especially those of us living in the northern hemispheres – supplementing Vitamin D is a must. I have been striving for 5-10,000 IU per day for the past several years now.  The best way to assess your need is of course to have your blood levels tested.  Then develop a strategy to raise them (as they more than likely are low).  Daily supplementation is one way or you can have a high dose injection of vitamin D as well.

If you have questions about your Vitamin D levels, let us know!  We are more than happy to help you find out your levels at our chiropractic clinic in Mendota Heights, or devise a strategy to optimize your Vitamin D levels.
