Is getting your vitamin D from pills the same as getting it from sun? Most people believe there’s no difference. This informative paper demonstrates the HUGE difference between the two pathways utilized to metabolize each source and why vitamin D from sun is non-toxic but vitamin D ingested orally causes toxicity, hypervitaminosis D and atherosclerosis EVEN IN LOW DOSES.
“Excess intake of vitamin D causes hypercalcaemic toxicity. However, experiments with different animal species have shown that long-term supply of oral vitamin D in apparently non-toxic amounts causes atherosclerosis in large arteries. A mechanism for this toxicity is proposed. Alternative strategies for addressing widespread vitamin D deficiency by food fortification should be considered in light of the angiotoxicity caused by oral vitamin D in animal experiments.
