Discussion: I am an HBV patient; blood tests indicated a deficient vitamin D. Should I be exposed to the sun or use supplements as suggested?

The sun is the source of life on Earth. People mistakenly avoid controlled sun exposure! Most people today have a chronic vitamin D deficiency. The additives are not absorbed as in the natural fortification of sun exposure. Vitamin D3 is a cholesterol derivative and has a far-reaching effect on the immune system, as many recent studies have shown in the context of the coronavirus.
