A new medical study has found taking a vitamin D supplement can help asthma sufferers could halve their risk of suffering a severe attack. Researchers at Queen Mary University of London found that the number of people visiting A&E because of an attack dropped from six per cent to three per cent in people taking vitamin pills.
Vitamin D are a cheap and effective way of cutting down on potentially deadly attacks. "These results add to the ever growing body of evidence that vitamin D can support immune function as well as bone health," said lead researcher Professor Adrian Martineau. Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.
Vitamin D was known until now especially because it promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. Vitamin D has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation. The FNB established an RDA for vitamin D representing a daily intake that is sufficient to maintain bone health and normal calcium metabolism in healthy people. For 19 – 50 age this is of 600 IU and increases up to 800 IU for elderly persons. Further clinical trials are on-going internationally to verify the new study, the researchers revealed.
