Vitamin D helps to prevent disease in most people, it is reported, according to a new study published Wednesday in the British Medical Journal.

During the winter months when the sky is constantly cloudy many people are looking for vitamin D supplements. This vitamin is essential for healthy skin, strengthening bones, muscles, teeth. But a review of the evidence of clinical studies on the effect of additives has shown that attempts to obtain vitamin D, this method is not profitable.

"We came to the conclusion that currently the data do not suggest using supplements of vitamin D to prevent disease," said mark Bolland, associate Professor of medicine at the University of Auckland, New Zealand. The Bolland conducted the study with Alison Avenell in the field of medical Sciences at Aberdeen University. Clinical studies additives do not reduce the risk of falling and bone fractures. But they recognize that this may be useful for people who are at high risk, e.g., elderly and dark-skinned people living in cold climates.

In spring and summer in remote areas of the Northern and southern hemispheres, for example, in the Northern United States and New Zealand, people generally get enough vitamin D through sunlight and foods in their diet. Vitamin helps the body absorb calcium to promote bone growth.

But in the autumn-winter period, the level falls. You need to eat the right foods such as fatty fish, egg yolks, red meat and liver, to maintain a high level of vitamin within the body.
