Recent research shows that higher levels of vitamin D in the blood are linked to better cardiorespiratory fitness
Vitamin D important for healthier heart and lungs - daily science news headlines

A new study showed an interesting link between the levels of vitamin D in the blood and the ability of the heart and lungs to supply oxygen to the muscles (cardiorespiratory fitness).

People that had the highest levels of vitamin D showed a 4.3-fold increase in cardiorespiratory ability, compared to the individuals with the lowest levels. The difference was significant even after adjusting for additional factors (age, sex, smoking, etc.).

It was known that vitamin D was good for healthy bones, but this study suggests it is also important for heart and lung functions. Clinical trials should be conducted to see if vitamin D supplements are beneficial, considering that people with higher cardiorespiratory fitness are healthier and live longer.
