Vitamin D3 is a fat-soluble secosteroid synthesised in skin on exposure to sunlight and obtained from a few foods. It functions as a hormone, regulating calcium balance, immune function and the expression of hundreds of genes. Liposomal delivery is used to improve absorption.
Vitamin D status is associated with immune resilience, bone integrity and overall mortality risk in large populations. Meta-analyses of randomised trials report a reduction in cancer mortality with supplementation, while effects on all-cause mortality are less certain — a nuance worth keeping in view.
Peer-reviewed studies on the active compound — citations link to PubMed.
“Vitamin D supplementation was associated with a reduction in cancer mortality but not all-cause or cardiovascular mortality in this meta-analysis of randomised controlled trials.”
“vitamin D administered daily reduced cancer mortality by 12 percent”
“Quantitative synthesis of human studies showed no significant effect of vit D intake for dysmenorrhea (2 studies, 44 vit D vs 44 placebo, mean -0.71, 95% CI -1.94, 0.51) and non-cyclic pelvic pain (2 studies, 42 vit D vs 38 placebo, mean 0.34, 95% CI -0.02, 0.71).”
“These findings suggest that antioxidant vitamins may alleviate pain in endometriosis patients by reducing inflammation.”
