Creatine is a popular sports supplement known for boosting energy levels in muscle cells during exercise. Recent research has also hinted at its potential benefits for brain health. A new study published in Scientific Reports has found that a high dose of creatine can enhance cognitive performance in individuals who are sleep-deprived.
The study involved 15 participants who took either a single high dose of creatine or a placebo on separate nights. Cognitive tasks were conducted at various intervals throughout the night. The researchers observed positive changes in brain metabolism and enhanced cognitive performance, particularly in processing capacity and short-term memory, following the creatine dose. This effect peaked at 4 hours but lasted up to 9 hours.
Experts believe that creatine-based interventions could be beneficial for individuals who need to perform at a high level despite insufficient sleep, such as healthcare professionals, firefighters, and night-shift workers. However, caution is advised due to the high dose used in the study, which may put strain on the kidneys. Future research is needed to explore the potential cognitive benefits of lower dosages of creatine or combinations with other components.
While creatine may show promise in improving cognitive function in certain circumstances, such as among older adults and individuals with sleep deprivation, more research is required to determine its efficacy in young individuals with a balanced diet. Additionally, sustained supplementation over an extended period may lead to more enduring cognitive benefits. Consulting with a qualified nutrition professional is recommended to ensure safe and effective use of creatine supplements.
