The first chart shows the observed vitamin D serum levels in the blood resulting from vitamin D supplementation. The red line shows the median (half of samples above and half below) level and the black lines show the ranges for 1014 people.

I have been taking 3000 IU Vitamin D per day so I feel a bit more comfortable after seeing these charts. Vitamins D and K both affect calcium metabolism, and I also supplement vitamin K2. The second chart shows the percentage decrease in disease incidence compared to a vitamin D serum reference level of 25 ng/ml. Higher vitamin D serum levels have a strong preventative relationship to many cancers.

This tactic to prevent skin cancers may lead to other serious diseases. The link to type 1 diabetes is new to me, as that indicates vitamin D is related to pancreas health. A healthy pancreas produces not only insulin but pancreatic enzymes that fight cancers. [/quote]    Insert an Image File
