Fats are the things that you should be more concerned about since these are the ones that decide what kind of figure to give your body. You must not lose more than one half pound of fat in a week because if this happens, your body will individually think that you are undergoing a fasting, trying to starve yourself. With omega 3, an athlete's heart is ready for long hours of strenuous activities. Omega 3 also helps in reducing heart rate; thus the heart releases enough oxygen to the brain and other organs. An athlete is less tired and weak if his heart pumps slower even when his body is at work. Any athlete who would want to take these oils as supplement should consult their physicians first. Although it is a significant component in nutrition, the intake of fats should be strictly monitored. Too much consumption of fats may lead to major health problems such as cancer and heart disease. The road to sports excellence is not easy. Along with fostering courage and determination, athletes have to follow the strict regimen brought on by natural sports nutrition. Vitamin supplements are commonly used if an athlete s diet is not enough for his energy requirements. Vitamin supplements provide "health insurance," as sort of back-up to ensure optimal sports nutrition. Multivitamin supplements with no more than 100% of the Daily Value (DV.) provide a safe and adequate balance of vitamins. Don't self-prescribe vitamin oil supplements or 'herbal' muscle grower without asking your physician first. Usually, these 'herbal' supplements go in the guise of herbal supplement, when in fact they are capsules of steroids. If you want to help your immune system, you can take megadoses of vitamin C. You need glucose to keep your blood sugar in normal levels. Glucose fuels the brain and the muscles during an activity. If you lack glucose in your body, you cannot think properly because your brain does not have enough fuel that it needs. Worse, you might faint even before the race begins of hypoglycemia.
