vitamin D is mainly obtained by sunlight (our body synthises it in the presence of sunlight)
rescent studies reveals the fact that this vitamin plays an crucial role in preventing heart disease
vitamin D prevents heart disease? In fact, most people suffering
from heart disease are chronically deficient in vitamin D. By
correcting their vitamin D levels (through sunlight exposure or by taking vitamin D3 supplements)
Most
nutritionally-aware doctors and naturopaths are now recommending
anywhere from 1,000 - 4000 IUs per day of vitamin D supplementation. Of
course, it is always better to avoid tablets by simply standing in sunlight for few minutes.
People should remember the total daily intake of vitamin D includes vitamin D from fortified milk and other fortified foods, cod liver oil,
supplements that contain vitamin D, and sunlight. People who receive
adequate sunlight exposure do not need as much vitamin D in their diet as do people who receive minimal sunlight exposure. Vitamin D increases both calcium and phosphorus absorption and has also been reported to increase absorption of aluminum. Increased blood levels of calcium (which may be a marker for vitamin D status) have been linked to heart disease
Osteoporosis is closely correlated to heart disease. Vitamin D deficiency
could certainly be a factor in both, because there is a strong inverse
relationship between vitamin D levels and artery calcification; the more
D in the blood, the
less the calcification. Artery cells have vitamin D receptors (VDR),
which when stimulated by vitamin D, inhibit the incursion of calcium.
Based on the evidence from these studies, there is no reason to take
vitamin D or calcium, ever. You can get all the vitamin D you need by
taking a walk in the sunshine, especially in winter, since sunlight stimulates natural formation of vitamin D. However, if you want to take vitamin D there is no risk
Vitamin D - reduces heart disease risk in women. It was reported at the
42nd annual conference on Cardiovascular Disease and Epidemiology
Prevention that women who take vitamin D supplements lowered their risk
of death from heart disease by one-third. The finding was an unexpected
dividend extracted from an osteoporosis trial to determine the incidence
of bone fracture in
nearly 10,000 older women. From the trial participants, 4200 women
reported taking vitamin D supplements at the onset of the study; another
733 reported a prior history of supplementation.
