Message: | However, not all human studies have confirmed this beneficial response and not every individual responds positively to creatine supplements. For example, people who tend to have naturally high stores of creatine in their muscles will not experience an energy-boosting effect from extra creatine. Preliminary clinical studies also suggest that creatine's ability to increase muscle mass and strength could hold special advantages for combating muscle weakness associated with various neuromuscular disorders.
Although not all clinical studies agree, some conducted in both animals and people have shown that creatine supplements improve strength and lean muscle mass during high-intensity, short-duration exercises (such as weight lifting). These positive effects were mainly seen in young people (roughly 20 years of age). Also, creatine along with resistance training has been reported to increase bone mineral density in elderly individuals, thereby reducing the risk for osteoporosis. Although it does not appear to improve physical endurance, there is some suggestion that speed for short periods of time may improve with use of creatine.
