On the contrary, holistic health is based on the premise that given what it needs, the body will correct itself. Left on its own to function in a deficient state, we now have an immune system to either reacts too little, or overreacts in an "auto-immune" state, malfunctioning in specific areas of the body.
D3 is the modulator that brings balance to this system.
I am only pointing out that your postings of a bunch of lab tests where they are directly juicing animals and people with straight 1,25 D have no basis in reality on a board like this where people are coming to find out if normal D3 intake and production can help them.
It only serves to confuse and mislead.
Also remember, Vitamin D is not a steroid, it's a secosteroid.
