You may want to add a new vitamin to your daily supplement routine. According to a new study conducted by Queen Margaret University in Edinburgh, vitamin D can not only lower the risk of heart disease, but also improve exercise performance.
Vitamin D, most commonly known for being generated by exposing the skin to the sun, can also be found in oily fish and eggs. However, often the amount of vitamin D obtained through diet alone is not enough. People who live in climates that get less sunlight are also often found to not get enough to vitamin D.
