I see that you are still highly confused about D3 in general and believe that there is a great difference between ingestion of a natural source such irradiated sheep lanolin or cod liver oil, and your body's own ability to make D3 through sunlight exposure. There is not, they both raise your 25D levels. Your attempts to confuse readers by calling D3 a drug are trite.
Another point of fear, uncertainty and doubt that you are trying to convey is that D3 is somehow immunosuppresive. How terribly incorrect. You claim the study on T-cell activation is "unsupported." You have obviously not read and understood the study.
These are not some hocus pocus "computer modeling."
Lastly, to reiterate, calcitriol injections are so far removed from what the general public will ever have to consider in their lifetime unless they are facing kidney failure, it only serves to confuse readers more by grouping such injections with common "D3" supplementation.
