FYI
Vitamin D is an action, and can not be synthesised.
It is the action of the Sun’s micro voltage through the skin, on the chlorophyll molecule, that produces red blood cells; with calcium as the only waste product.
D2/3 are further down the chain, and only a meagre substitute for fresh greens and sunlight.
Also. It is true that any virus will feast on undigested protein and sugar.
