Increase Vitamin D, Improve Stamina

According to a recent study, vitamin D not only lowers the risk of heart disease but also helps you exercise more strenuously and increase endurance. To say it differently, get enough of vitamin D and you can work out in the gym longer.

In the study, carried out by researchers from Queen Margaret University in Edinburgh, UK, subjects were matched by age and weight and either given 50 micrograms of vitamin D or a placebo every day for two weeks.

The participants who took the supplement not only showed lower blood-pressure levels, but also had lower levels of the stress hormone cortisol. What was most surprising was that in a fitness test, participants who’d taken the supplement were able to cycle, on average, 6.5km in 20 minutes, compared to just 5km before the study started. Even with the 30% increase in distance, participants showed lower signs of physical exertion.

Many people don’t get enough vitamin D through diet alone, but you can fix this easily — just head to the beach. Exposing skin to ultraviolet B rays generates significant amounts of vitamin D in the body.
