Vitamin D: So really, when do I have enough?


Hello health interested friends:

As you may be aware, there has been in the last few years a recognition that most of us are Vitamin D deficient. Recently, the Food and Nutrition Board re-confirmed that they felt that research was not conclusive enough about Vitamin D's many gene expression possibilities to ascribe any function to Vitamin D except bone calcium metabolism with respect to bone.

Friends, if you believe that I have a bridge I want to sell you!

Please, if you are interested in this amazing vitamin that affects literally thousands of genes and potentially many health conditions, consider subscribing to the Vitamin D's Council newsletter.

Dr. John Cannell, MD has done a wonderful job of getting the research summarized so everyone can understand this important topic.

The truth is if you are deficient of a vitamin, it will affect your health. How much depends on your natural metabolic redundancy that is available to offset the deficiency and to what degree environmental factors inhibit your body's ability to use these various duplicated metabolic pathways. Vitamin D which affects so many genes and their expression does seem to have multiple set points, the lowest being proper utilization of calcium, but other uses of Vitamin D, such as immune function and neurological optimization, require higher doses.

In Dr. Cannell's recent newsletter he has suggested 3 set points:

1. The level at which the parathyroid hormone is suppressed. From research that is about 20 ng/ml.
2. The level at which Calcium absorption is maximized. That is at 30ng/ml.
3. Still another set point to consider is at what point does the breast milk of a lactating woman have sufficient Vitamin D for her child. Dr. Bruce Hollis has shown that level is at 50ng/ml.

Significantly, it is above 50 ng/ml that protective effects occur for various cancers including breast cancer. For immune compromised individuals or people with Vitamin D receptor issues, still higher amounts are needed.

So, I test all my patients for their Vitamin D levels and through sun exposure and supplementation strive to get them above 50 ng/ml. If you are interested in testing your Vitamin D levels only, the simple blood test (from a Labpro blood draw station) costs $51.00 which includes the blood draw fee. Typically, I include only $5-10 more for invoicing so that all my patients get the best possible price that is out there for lab work.

If you are a current patient, please call to get a lab form if you have not checked this important health marker recently. If not a patient, you may want to consider a full intake to review your health and preventative measures you can take now. This is part of my Wellness Program.

Looking forward to hearing from you.

In good health,

Chuck Belanger, L.Ac.
