Why It Works

Key Benefits

🧪
5 g Creatine Monohydrate per Serving
Each serving (one 5 g scoop) provides 5,000 mg of creatine monohydrate as an unflavored powder. The container holds 250 g (50 servings) and no other ingredients are listed. Suggested use is one scoop in 8 oz of water or a beverage once daily.
💪
Strength and Power: Small Average Gains with Training
A meta-analysis of 69 randomized trials found small but statistically significant improvements in bench or chest press, squat strength, vertical jump and peak power with creatine, especially combined with resistance training, compared with placebo. Improvements were seen in younger but not older adults, and in males but not females. Handgrip and leg press strength did not differ significantly.
🏋️
Muscle Mass and Function in Older Adults: Mixed Results
A 2026 meta-analysis of 11 trials in adults aged 60 and older found that creatine added to resistance training gave a small additional gain in muscle strength (moderate-certainty evidence); the effects on muscle mass and physical function were not statistically significant. Earlier reviews reported gains in lean tissue mass, but results depended on the dosing strategy used.
🩺
Raises Serum Creatinine: Tell Your Clinician
In meta-analyses of randomized trials, creatine raised serum creatinine, the blood marker used to estimate kidney function, by about 0.13 to 0.14 mg/dL on average, without a significant change in GFR measured by Cr-EDTA. The authors said this likely reflects altered creatinine metabolism rather than kidney injury. Ask a doctor before use if you have kidney disease, and tell your clinician about creatine before kidney blood tests.
🧠
Brain: Limited and Equivocal Evidence
Creatine supplementation can raise brain creatine content in humans, but a systematic review described the effects on cognition as somewhat equivocal, and a systematic review in older adults found limited evidence (six studies, two of them double-blind supplementation trials) and called for high-quality trials. This product has not been studied for cognition.

🔬
The International Society of Sports Nutrition position stand reported that creatine supplementation increases intramuscular creatine concentrations and that short- and long-term supplementation (up to 30 g per day for 5 years) was safe and well tolerated in healthy individuals and in a number of patient populations. Some of the authors are affiliated with supplement companies.

A systematic review and meta-analysis of 69 randomized trials (1,937 participants) found that creatine plus resistance training produced small but statistically significant improvements in bench and chest press (1.43 kg), squat strength (5.64 kg), vertical jump (1.48 cm) and Wingate peak power (47.81 W) compared with placebo, with no significant difference in handgrip or leg press strength. Significant gains were seen in younger but not older adults, and in males but not in females.

🔬
A meta-analysis of 23 studies in adults under 50 (mostly males: 20 studies of males, 2 of females, 1 of both) found that creatine plus resistance training increased upper-body strength by 4.43 kg and lower-body strength by 11.35 kg compared with placebo; males gained significantly in both, whereas females showed no significant gains.

🔬
A systematic review and meta-analysis of 11 randomized trials in adults aged 60 and older found that creatine plus resistance training improved muscle strength slightly more than resistance training alone (g = 0.31; moderate-certainty evidence). The effects on muscle mass (g = 0.35, 95% CI -0.09 to 0.78) and physical function (g = 0.47, 95% CI -0.08 to 1.03) were not statistically significant, and the findings should not be extrapolated to frail or sarcopenic older adults.

🔬
A systematic review and meta-analysis of randomized trials in postmenopausal women (7 trials, 608 participants) reported small gains in lean mass (+0.37 kg) and leg-press strength (+7.5 kg) with creatine, with benefits seen when 5 g per day or more was combined with resistance training; bone density was unchanged overall and adverse events and renal indices were similar to placebo.

🔬
In 31 men, ingesting 20 g of creatine per day for 6 days raised muscle total creatine by about 20%; ingesting 3 g per day for 28 days produced a similar but more gradual 20% increase, and 2 g per day maintained the raised level. The authors concluded that 3 g per day is likely, in the long term, to be as effective at raising tissue creatine as the higher dose.

In a 4-week randomized trial of 19 recreational male bodybuilders taking 5 g of creatine immediately before or immediately after exercise, fat-free mass and bench press rose over time in both groups, with no significant interactions between timing and time; the authors' magnitude-based analysis suggested post-workout supplementation was possibly more beneficial. The study was small and used magnitude-based inference.

What studies of creatine monohydrate show

  • Strength and power: small average improvements in some lifts, jump height and peak power when creatine is combined with resistance training, mostly in young males
  • Muscle mass and function in older adults: mixed results; strength gains were small and effects on muscle mass and physical function were uncertain in a 2026 meta-analysis
  • Blood tests: creatine raises serum creatinine, a marker used to estimate kidney function, without a consistent change in measured kidney filtration
  • Brain: supplementation can raise brain creatine, but systematic reviews describe the effect on cognition as equivocal or limited

The science behind creatine monohydrate

Creatine and strength

A meta-analysis of 69 randomized trials (1,937 participants) found that creatine, especially combined with resistance training, produced small but statistically significant improvements in bench or chest press (1.43 kg), squat strength (5.64 kg), vertical jump (1.48 cm) and Wingate peak power compared with placebo, but no significant difference in handgrip or leg press strength. Improvements were seen in younger but not older adults, and in males but not in females. Kazeminasab 2025 · Wang 2024

Creatine in older adults

A 2026 meta-analysis of 11 randomized trials in adults aged 60 and older found that creatine added to resistance training improved muscle strength slightly more than resistance training alone (small effect, moderate-certainty evidence); effects on muscle mass and physical function were not statistically significant. An earlier meta-analysis reported greater gains in lean tissue mass and strength with creatine, but when studies with a loading phase were excluded, creatine had no greater effect on chest or leg press strength. Yao 2026 · Forbes 2021

Creatine and kidney blood tests

Meta-analyses of randomized trials found that creatine raises serum creatinine by about 0.13 to 0.14 mg/dL on average. In one, estimated GFR did not change significantly; in another, creatinine-based GFR estimates fell while GFR measured by Cr-EDTA did not change significantly, which the authors said likely reflects altered creatinine metabolism rather than kidney injury. Long-term randomized data beyond one year are lacking, and concerns persist about people who already have kidney disease. Tell your clinician if you take creatine before kidney blood tests. Tsiaras 2026 · de Souza Almeida 2026 · Pereira 2026

Creatine and the brain

Preliminary studies indicate that creatine supplementation can increase brain creatine content in humans. A systematic review described the effect on cognition as somewhat equivocal, and a systematic review in older adults found limited evidence, mostly from studies of fair or poor methodological quality, and called for high-quality clinical trials. Forbes 2022 · McMorris 2024 · Marshall 2026

Creatine timing

In a 4-week trial of 19 recreational male bodybuilders, fat-free mass and bench press rose over time in both groups, and no significant differences were found between 5 g of creatine taken immediately before versus immediately after workouts; the authors' magnitude-based analysis suggested post-workout intake was possibly more beneficial. The study was small. Antonio 2013
