Creatine is a very popular supplement. Using creatine significantly impacts force production regardless of sport, sex or age. For exercise lasting less than 3 minutes, effect size of creatine on lower body strength is small to moderate (0.235) and a little larger for the upper body (0.317).
Creatine may also be of benefit in other modes of exercise such as high-intensity sprints or endurance training. However, it appears that the effects of creatine diminish as the length of time spent exercising increases.
Several studies have found no adverse effects of creatine usage. Some studies have reported increased hair-loss. Thus it may be a good idea to stick to the recommended dosage. 😅
