Page 388 Daily 5 mg of cholecalciferol or 200 IU of Vitamin D. However, 800 IU/Day is shown to reduce the incidence of osteoporotic fractures. 800 IU/Day recommended by the Institute of Medicine to maintain bone health. Frank deficiency is when the levels of 25-hydroxycholecalciferol (25OHD) is less than 20 ng/mL (50 mmol/L) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6305614/ No consensus that the oral vitamin D supplements are helpful Ergocalciferol from plants is called Vitamin D2 Cholecalciferol from the animal tissue is called Vitamin D3 7 deidro-cholesterol to (UV light) to cholecalciferol (D3) to 25 hydroxylase in liver to 25 OH D to -hydroxycholecalciferol 1-hydroxylase in kidney to 1,25 DiOH D3 Vitamin D Receptors are abbreviated to VDR in the notes. These are cytosolic receptors. https://www.newscientist.com/article/2121424-vitamin-d-supplements-may-prevent-millions-of-winter-infections/ Deficiency of vitamin D makes people more susceptible to respiratory tract infections. Vitamin D supplement can reduce these infections by 12% Keep in mind, this is for those who are deficient in this vitamin. If you are not deficient, then it will not make a difference.

This in turn causes more production of cathelicidine and beta defensins 4. Vitamin D also affects monocytes to reduce production of IL1, IL6, IL8, IL12, and TNF. Regulating the immune response. Vitamin D acts on the dendritic cells to inhibit/reduce their differentiation and maturation. It reduces their MHCII expression, co-stimulatory molecules like CD40, CD80, CD86, decreased production of IL-12 etc. 2013 Study https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756814/ Vitamin D improves immune system by helping produce cathelicidine and by helping modulate inflamm ... https://www.youtube.com/watch?v=wJyT1YSwe-8
