Quick Answer
Creatine Cognition Sleep Deprivation Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: There is some evidence that creatine supplementation improves outcome measures in those with muscular dystrophy but not other neurological diseases or conditions such as Parkinson’s disease or amyotrophic lateral sclerosis.
Key Takeaways
- 01There is some evidence that creatine supplementation improves outcome measures in those with muscular dystrophy but not other neurological diseases or conditions such as Parkinson’s disease or amyotrophic lateral sclerosis. [Candow Darren G. (2023)]
- 02The vast majority of evidence-based research has focused on the efficacy of creatine monohydrate and exercise (primarily resistance-type training) for improving measures of muscle/lean mass, muscle performance (including strength, endurance, and power), and recovery from sport or exercise in young healthy male adults []. [Candow Darren G. (2023)]
- 03There is evidence that high-dose creatine supplementation (e.g., ≥ 20 g/day) can yield increases in creatine levels in the brain over periods of several weeks and perhaps overcome a reduction in endogenous creatine synthesis inside the CNS [], but the replenishment of the brain creatine pool is still slow and limited []. [Candow Darren G. (2023)]
- 04Creatine supplementation can improve cognition and memory, especially in older adults or during times of metabolic stress (i.e., sleep deprivation). [Candow Darren G. (2023)]

- Creatine, a nitrogenous organic compound derived from reactions involving the amino acids arginine, glycine, and methionine, is important for resynthesizing ATP, particularly during times of increased metabolic demand (e.g., sleep deprivation, mental health conditions, or neurological diseases) [,,]. [Forbes Scott C. (2022); evidence level 3]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
