Vitamin D levels

This will be a real quick post. I found this chart on a lecture by Medical Herbalist Paul Bergner and thought it was very impressive. This shows what happens by blood level of Vitamin D. Notice the California lifeguard in the summer had a level of 70-80 nanograms per milliliter, while the average American tested only had 24!

• 150 ng/ml No toxicity noted at this level (twice normal physiological levels)
• 70-80 ng/ml California lifeguard tested in the summer
• 50 ng/ml Mother stops secreting D3 in breast milk; at this level and above breast cancer risk falls by 50%. Below this level risk increases substantially.
• 38 ng/ml Colon cancer risk at 60%; neuromuscular function impaired
• 32 ng/ml Calcium absorption impaired; bone loss occurs
• 24 ng/ml Average American levels in recent survey; parathyroid hormone is suppressed
• 15 ng/ml Necessary to prevent rickets and osteomalacia; respiratory infections double
  

It is easy to see that at lower levels our respiratory immunity is severely weakened. This means more colds and flu for us. So keep the Vitamin D levels up!! You can have your levels tested at a doctor's office or go to www.vitaminDcouncil.org for a home test kit.
