Vitamin D Can Improve Your Workouts

Along with setting the clocks back for Daylight Savings Time comes colder weather, less sunshine, and vitamin D deficiencies for many people. It’s not something we often consider, but is certainly understandable. For those of us who work a typical work week, it’s dark when we wake up, and dark again when we leave the office. If your job keeps you indoors most of the day, there really isn’t much time to be getting the vitamin D that our bodies require from the outdoors.

A lack of vitamin D can cause various health problems and is an important hormone for our bodies. Vitamin D is used in the formation of bones and teeth, and is necessary for the proper absorption of other nutrients. It may also play a role in preventing cancer, cardiovascular disease, Alzheimers, diabetes, depression and weight gain.

Natural sources of vitamin D include:

  • Sunshine
  • Fatty fish – salmon, trout, mackerel, tuna and eel
  • Canned tuna fish
  • Fortified milk
  • Some types of orange juice – ex. Florida Natural and Minute Maid
  • Egg yolks
  • Fortified cereal

Unfortunately it can be difficult to get enough vitamin D through your diet alone.

In addition to the associated health implications, research has shown that maintaining adequate levels of vitamin D reduces the risk of heart disease, but also helps you improve your performance during exercise.

In a recent study, participants were given either 50 micrograms of vitamin D every day for two weeks, or a placebo. The results showed that those who were given the vitamin D each day had lower blood pressure levels, lower levels of cortisol (the stress hormone), and more interestingly were able to cycle, on average, 6.5 km in 20 minutes, compared with just 5 km before the study began two weeks prior. They also showed lower signs of physical exertion even though they had increased their distance.

With this in mind, ensuring you are supplementing your natural vitamin D intake is certainly something to consider.
