Vitamin D3 is not a vitamin at all- it is a secosteroid when metabolised by the human body. It is the most misunderstood molecule in the world in terms of its impact on human health. Do not confuse vitamins or other supplements with D3- chloecalciferol- or calcitriol- as metabolised by the body. This is steroid medicine and the results commensurate with that of other similar- though man made- compounds.

The theraputic effect of 50 ng/ml serum concentrations of D3 are only recently coming to the fore in terms of recognition by the mainstream medical community. Every reader concerned about his/her health needs to investigate D3 in depth and follow developments as major brreakthroughs are reported daily- weekly. While this report provides long term treatment for diabetics D3's most profound impact will be in treating/avoiding cancers of most types. The link between low D3 and cancer is irrefutable and clear. Also its association with diabetes, autism, depression, Alzheimer's, obesity, influenza, heart disease, and a host of other major killers grows stronger each week.
