There is little you can do in order to avoid a cold or flu. One of the things that can protect you from colds is vitamin D. Despite the fact that vitamin C was the one recommended for flus and colds, vitamin D supplements might be the best way to stay away from colds
British scientists from Queen Mary University focused on the benefits of Vitamin D supplements in preventing colds. The researchers mentioned that taking supplements of vitamin D can protect you from respiratory tract infections.
Scientists noted that when people suffer from colds and even pneumonia or bronchitis their levels of vitamin D are smaller than normal. Previous studies also showed that this vitamin can be responsible for triggering an immune response to some viruses and bacteria.
In order to show the benefits of this vitamin, researchers took multiple trials. The trials involved more than 11,300 people. The participants were aged between 1 and 95 years. After they analyzed data from the trials researchers observed that those who had higher levels of vitamin D had a lower risk of developing acute respiratory tract infection.
Further analyses showed that people benefited more when they took weekly or even daily supplements of vitamin D. Of course, the ones who had lower levels of vitamin D in their blood at the begining of the study benefited more from the positive effects of the supplements.
“Our study reports a major new indication for vitamin D supplementation: the prevention of acute respiratory tract infection,”
Study authors added that they need to make more tests on this topic before they are sure of the effectiveness of vitamin D in preventing colds. Many experts were skeptical about these findings because they believe that they were not sufficiently applicable for the general population.
Other experts that were not involved in the study said that the current findings are not enough to support the use of supplements of vitamin D as a way to prevent colds. The only health problem that can be prevented by vitamin D supplements is osteomalacia.
What is your opinion about this study? Do you think that vitamin D supplements can protect us from colds?
