The effects of vitamin D now include life extension. "We may finally have a vitamin that translates into greater longevity," declared Robert A. Vogel, M.D., professor of coronary medicine at theUniversity of Maryland, Baltimore. Dr. Vogel noted that beyond vitamin D's well-established effects upon calcium and bone, the hormone vitamin also functions in gene regulation, management of cell proliferation and differentiation, production of antibiotic peptides, stimulation of innate immunity, and vitamin D is a remarkable pain reliever. And the research keeps mounting up that vitamin D not only reduces mortality at all ages, particularly in the elderly, but also extends the life span.
The ability to turn back the clock on the basic biology of human aging by a full 5 years via vitamin D supplementation is impressive. Staying thin and being physically active provides similar longevity benefits, but it's hard to come by an inexpensive nutritional supplement that extends life. Vitamins A, B, C, and E have beneficial effects on the body and help prevent disease, but none actually turn back the clock of aging.
To get its longevity benefits, you have to racket up your serum levels of vitamin D. Sunshine helps, and getting out of the gym and exercising outdoors provides double longevity benefits. However, to get optimal vitamin D levels, you need to take supplements, but don't overdo it as too much can be potentially toxic to your liver. The standard daily dose used to be 400-800 IU taken with meals, but now 1,000-2,000 IU is recommended, based on serum levels. A positive longevity daily dose is 2,000-4,000 IU, and in some cases high dose bursts may be necessary to get serum
