Q10 is involved in the energy turnover in all cells. The highest concentration of the compound is found in the heart, as this muscle needs to pump day and night and to supply muscle cells with more blood when we are physically active. The cellular energy turnover takes place inside some minute powerhouses called mitochondria. A Danish-Swedish study has shown that the mitochondria in the muscle cells of top-notch athletes have a different construction that makes them able to produce up to 25 per cent more energy. Earlier studies show that Q10 is able to improve athletic performance, and it all boils down to optimizing the energy turnover in the cells.

According to a study that was presented to a group of endocrinologists at an Edinburgh conference, supplements of vitamin Dmay improve sports performance and reduce the risk of cardiovascular disease. One of the things vitamin D does is to block the stress hormone cortisol that makes your blood pressure go up. The problem is that many people lack vitamin D, not only in the winter time but even during the summer period.
