Study type could not be determined · Population basis: unknown · Directness: not assessedStudies in both laboratory and sports settings have found that short-term creatine supplementation (for 5 to 7 days) in both men and women often significantly increases strength (e.g., for bench presses) and power (e.g., for cycling), work involving multiple sets of maximal effort muscle contractions, and sprinting and soccer performance [112,115]. In one example, a study randomized 14 healthy, resistance-trained men (age 19–29 years) to receive 25 g creatine monohydrate or a placebo for 6–7 days [116]. Participants taking the supplement had significant improvements in peak power output during all five sets of jump squats and in repetitions during all five sets of bench presses on three occasions. In another study, 18 well-trained male sprinters age 18–24 years received either 20 g/day creatine or a placebo for 5 days [117]. Compared with those taking the placebo, participants taking the creatine improved their performance in both 100-meter sprints and six intermittent 60-m sprints.

Study type could not be determined · Population basis: unknown · Directness: not assessedStudies have found no consistent set of side effects from creatine use, except that it often leads to weight gain, because it increases water retention and possibly stimulates muscle protein synthesis [112,113]. Several studies have found that supplemental creatine monohydrate, when used for a strength-training program, can lead to a 1–2 kg increase in total body weight in a month [73].

Study type could not be determined · Population basis: unknown · Directness: not assessedIn a position statement, the AND, DoC, and ACSM advise that creatine enhances performance of cycles of high-intensity exercise followed by short recovery periods and improves training capacity [12]. In its position statement, the ISSN states that creatine monohydrate is the most effective nutritional supplement currently available for enhancing capacity for high-intensity exercise and lean body mass during exercise [112]. The ISSN contends that athletes who supplement with creatine have a lower incidence of injuries and exercise-related side effects compared to those who do not take creatine [112]. The Australian Institute of Sport supports the use of creatine for improving sports performance in suitable athletic competitions under the direction of an expert in sports medicine, but it notes that more research might be required to understand how the supplement should be used for best results [29].
A typical protocol for creatine supplementation in adults, regardless of sex or body size, consists of a loading phase for 5–7 days, when users consume 20 g/day creatine monohydrate in four portions of 5 g, followed by a maintenance phase of 3–5 g/day [112-114]. In some studies, the loading dose is based on body weight (e.g., 0.3 g/kg) [114]. Another creatine supplementation protocol consists of taking single doses of about 3–6 g/day (0.03–0.1 g/kg body weight) for 3 to 4 weeks, without a loading phase, to produce ergogenic effects [112,114,119].
Creatine monohydrate, which is 88% creatine by weight, is the most widely used and studied form [112,114,123]. Other, usually more expensive, forms of creatine (e.g., creatine ethyl ester, creatine alpha-ketoglutarate, and buffered forms of creatine) have not been proven to have superior ability to creatine monohydrate for enhancing muscle creatine levels, digestibility, product stability, or safety [73,112,123].
