Recommended to fight cancer, heart disease, Crohn's disease and diabetes. Buy this Vitamin D supplement because studies have shown that this supplement reduces death rate by 7%. Vitamin D supplements are now recommended by The UK Foods Standard Agency and the Canadian Cancer Society. In theory adults between the ages of 19 and 50 should make enough vitamin D in summer from the action of sunlight on the skin, although even this is not true for all of them.
Seven out of ten U.S. children have low levels of vitamin D, raising their risk of bone and heart disease, according to a study of over 6,000 children by researchers at Albert Einstein College of Medicine of Yeshiva University. The striking findings suggest that vitamin D deficiency could place millions of children at risk for high blood pressure and other risk factors for heart disease. (source)
In the November 2009 edition of the journal Pediatrics researchers suggest that all US children take vitamin in D supplements, because of the generally low levels that they found and the potential health benefits of boosting vitamin D to normal levels. Vitamin D improves bone health and prevents rickets in children, and recent studies suggest that it also may prevent a host of common childhood illnesses, including respiratory infections, childhood wheezing, and winter-related eczema.
According to researchers at National Jewish Health low levels of vitamin D are associated with lower lung function and greater medication use in children with asthma. In a paper published in the Journal of Allergy & Clinical Immunology, (April 2010) Daniel Searing, MD, and his colleagues reported that vitamin D enhances the activity of corticosteroids, the most effective controller medication for asthma. "Asthmatic children in our study who had low levels of vitamin D were more allergic, had poorer lung function and used more medications," said Dr. Searing. "Conversely, our findings suggest that vitamin D supplementation may help reverse steroid resistance in asthmatic children and reduce the effective dose of steroids needed for our patients."
The American Academy of Pediatrics, which recently updated its vitamin D guidelines, now recommends that infants, children, and teens should take 400 IU per day in supplement form.
The American Heart Association reports that "Low levels of vitamin D were associated with increased risk of high blood pressure, high blood sugar and metabolic syndrome in teenagers".
Low vitamin D levels have been linked to heart disease, diabetes and cancer, particularly in later life. An article in the Archives Of Internal Medicine (2007;167:1709-1710) reviewing studies involving more than 57,000 people shows that vitamin D supplements can reduce death rates by 7%. Women undergoing treatment for breast cancer have also been recommended to take extra vitamin D to safe guard their bones.
Sources of vitamin D include oily fish and eggs, and in fortified foods such as margarine, breakfast cereals, bread and powdered milk. But most people's main source of vitamin D is sunlight, but there are some concerns that the exposure of some people is not sufficient.
Many of the elderly spend very little time outdoors, and dark-skinned people who live in temperate climates - melanin in their skin blocks the sunlight. Vitamin D helps regulate the amount of calcium and phosphate in the body, and so helps to keep bones and teeth healthy. It is also thought to be important for the immune system.
The UK Foods Standard Agency recommends that older people, those who always cover their skin or rarely go outdoors, those who eat no meat or oily fish, and those of Asian origin should take 10 micrograms (0.01 mg, 400 i.u.) of vitamin D each day. The agency also recommends pregnant or breast-feeding women to take a vitamin D supplement, although you might wish to consult your doctor first. The Canadian Cancer Society recommends that adults take a vitamin D supplement in fall and winter "due to our northern latitude and because the sun's rays are weak".
A study published in Archives Of Neurology found that 55% of Parkinson's disease patients had insufficient levels of vitamin D compared with 36% of healthy elderly people.
"Vitamin D insufficiency has now reached epidemic proportions and has been linked to increased body fat and decreased muscle strength." (Journal of Clinical Endocrinology & Metabolism February 2010)
Diabetics with low levels of Vitamin D appear to benefit from vitamin D supplements as it to stops cholesterol from forming plaque and damaging the arteries.
John White, an endocrinologist at the Research Institute of the McGill University Health Centre, led a team of scientists from McGill University and the Université de Montréal in an investigation of inflammatory bowel disease. He says of his research: “Our data suggests, for the first time, that Vitamin D deficiency can contribute to Crohn’s disease.”
