Recent studies have shown that Vitamin D is effective in preventing colds and the flu. Other studies found that it is even more effective than flu shots in fighting the flu. Adding Vitamin D to food could help prevent symptoms.

Up Your Vitamin D and Keep the Colds and Flu Away

Recent research suggests that the more sunshine vitamin we absorb, the less at risk we’ll be of contracting respiratory infections like colds and the flu. This is especially true for people who don’t get enough Vitamin D from sources like certain foods or sunlight.

Researchers pooled data from 25 studies that included more than 10,000 participants. The studies looked at whether vitamin D supplements cut the number of infections.

“We found that, overall, there was a modest protective effect,” says Dr. Adrian Martineau, a clinical professor of respiratory infection and immunity at Queen Mary University of London who led the research team.

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


Despite the various studies that have been conducted on this topic, this opinion is not shared by all experts. There’s not sufficient evidence to formally conclude that Vitamin D is 100% effective in fighting colds and the flu. However, since this is an ongoing debate, they do recommend people to consider taking supplements or use other alternative ways to increase Vitamin D production, especially during the colder months.

Promoting Vitamin D Production

Vitamin D productionVitamin D is a fat-soluble vitamin that we can find in certain (very few, actually) foods. It can be added to other foods, and it’s also available as a dietary supplement. Another way to trigger Vitamin D production is through exposure to UV rays from sunlight or alternative tanning options like sun beds.

Spring is here!

vitamin DSpring officially started on March 20th for the Northern Hemisphere! In fact, March marks the first month that everyone around the world can receive adequate Vitamin D from safe sun exposure. However, March is also the month when Vitamin D levels are the lowest for those living in northern mid-latitudes. Get outside and enjoy the sunshine, but keep in mind these important facts:

  1. Do NOT burn. You only need to expose your skin for around half the time it takes for your skin to turn pink.
  2. Wait to apply sunscreen. Sunscreen blocks Vitamin D production. So, while it’s important to protect your skin, allow yourself some time outside in the sunshine without sunscreen.
  3. If your shadow is shorter than you are tall, the sun is at the right angle for your skin to make Vitamin D.
