Hi All

Thank you for your contribution. For this thread to reach its full potential it is really important that you check and let us know please if your readings are in ng/ml or nnmol/L because

1ng/ml = 2.5nnmol/L

which makes a big difference ! (-:


And once again the real issue here is that these researchers are finding benefits at the higher normal range levels of vitamin D which are maybe double or more the current optimal recommendation range of 30 ng/ml = 75nnmol/L; they argue that the recommendations need to catch up with the research and levels of vitamin D found in 'beach guards' (people who get significant sun exposure without sunscreen) and wild primates.

The recommendations were formulated around rickets, which can be prevented with relatively modest amounts of vitamin D. Reductions in cancers etc were seen at higher vitamin D levels as illustrated by this chart which brings together information from a number of papers, and is referred to in one of the early videos on the vitamin D thread. http://www.grassrootshealth.net/dipchartng

This is a bit of a need to scream because it is such an important topic that is not given the attention it deserves. I cannot stress enough how worthwhile the Holick lecture is for background; the breast cancer lectures are also highly thought provoking.
