Vitamin D Can Help You Protect Against Cold and Flu


We all know that vitamin D is essential for a healthy body, especially for our bones, however taking vitamin D supplements have always been in controversy. Do vitamin D supplements really help in safeguarding our immunity? According to a recent research, they do.

A recently published research suggests that the vitamin which we mainly get from sunshine helps in reducing the risk of respiratory infections like cold and flu, particularly those people who do not get enough vitamin D through their diet or are not exposed to sunlight as much.

In order to reach the findings, the researchers collected data from around 25 studies which included more than 10,000 participants. All the studies evaluated by the researchers looked at whether vitamin D supplements reduced the number of infections in the participants.

Commenting on the findings of the study, a clinical professor of respiratory infection and immunity at Queen Mary University of London who led the research team, Dr. Adrian Martineau said, “We found that overall there was a modest protective effect.” He said that they found out that vitamin D supplements reduced the infection risk by almost 10 percent.

The findings of the research stated that the participants who were vitamin D deficient noticed a lot of benefits when they started taking the supplements. Reports state that their infection was cut by almost half.

“What we found is that those with the lowest vitamin D levels experienced the greatest benefit from supplementation,” Martineau added.

A professor of epidemiology at Harvard Medical School and a senior author of the study, Carlos Camargo said that serious respiratory infections are responsible for millions of emergency department visits in the United States each year. Camargo said that the findings of the study supports the notion that a larger number of food products should be fortified in vitamin D.

Since humans essentially get vitamin D from the sunshine and a few food products, there is a requirement for more food products to be fortified with the particular vitamin. Many milk products and even orange juice in the market can be found fortified with vitamin D.
