Caffeine facilitates the release and utilization of the body's fatty acids as a source of energy exercise. Thus, muscle glycogen is saved for later stages of prolonged aerobic events. Caffeine-containing beverages, due to their diuretic effect, should be used in addition to other fluids, not as a substitute. Research studies that identify caffeine as a health concern are not conclusive. As research continues to investigate caffeine's impact on health, a moderate intake of 200-300 mg of caffeine per day is suggested.
Moderation makes good sense.
