The fact that vitamin D prevents cancer is now so well known that even some conventional physicians are beginning to recommend it. Vitamin D prevents 77% of all cancers, after all. That’s as close to a “cure” for cancer as you’ll ever get (and it’s free, too, since you can make it yourself!).

But did you also know that 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), people can simultaneously halt cancer and prevent heart disease, too.

Here’s a collection of research revealing the amazing power of this “miracle” vitamin to eliminate heart disease. I’d like to add, though, that the previously recommended daily intake of 400 IUs of vitamin D is now considered hazardously low. Most nutritionally-aware doctors and naturopaths are now recommending anywhere from 1,000 – 4000 IUs per day of vitamin D supplementation. Of course, you don’t need any vitamin D supplements if you get sufficient sunlight on your skin on a regular basis.

Vitamin D prevents heart disease

Diabetes, both type-1 and type-2, are profoundly linked to low vitamin D levels. Obesity, heart disease, hypertension and stroke are inversely related to sunlight exposure and vitamin D levels. Psoriasis, eczema, and periodontal disease are lessened by sunlight exposure and high serum vitamin D. Fertility is positively influenced by sunlight exposure and high vitamin D levels. Sunlight enhances immune system function by producing vitamin D. Dozens of disorders other than those mentioned in this summary are related to vitamin D deficiency.

Vitamin D supplements are likely to be useful in preventing diabetes in areas where vitamin D deficiency is common. In a 1997 study looking at the links between environmental factors and Type II diabetes, vitamin D levels were assessed in 142 Dutch men aged from 70 to 88 years of age. Thirty-nine per cent were found to have low vitamin D levels and tests showed that low vitamin D levels increased the risk of glucose intolerance. Heart disease: Low vitamin D levels may also increase the risk of atherosclerosis.

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.

“I think vitamin D is an important ingredient in the longevity recipe,” he said enthusiastically, as if just struck by an epiphany. “Your skin manufactures vitamin D when it comes into contact with the sun. Without that vitamin D, we increase our risk for nearly all age-related diseases including many types of cancer, high blood pressure, diabetes and even autoimmune diseases like MS (multiple sclerosis).” Insufficient vitamin D markedly accelerates heart disease in kidney patients.

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.

To ensure adequate supplies of vitamin D, get at least twenty minutes of sun exposure on the face and hands each day. If that is not possible, take 400 to at most 1,000 milligrams of vitamin D supplements daily. Do not take more than 1,000 milligrams of vitamin D daily or take the supplement for more than six months; excessive use of vitamin D is associated with atherosclerosis and heart disease. Vitamin D is needed for calcium to enter bones, and a deficiency of this vitamin is a major risk factor for both osteoporosis and bone fracture.
