Although ingesting a range of vitamins and minerals is vital to overall health and energy, a couple of nutrients are key to high energy levels.  Our cells produce coenzyme Q10 (CoQ10) to help convert food into energy, but as we age our bodies produce less of it, which may make us feel tired.  If you have a healthy diet and are still battling fatigue, try taking a 100 milligram CoQ10 supplement two or three times daily.  Keep in mind that it may take up to two months to see effects.
