Does creatine also help ordinary people, not just athletes?
Creatine is not just for athletes. Combined with resistance training, it helps older adults gain muscle strength, and probably also improves memory.
Creatine monohydrate has the best-proven effects in older adults: it increases muscle strength and muscle mass, but only when combined with regular resistance training for at least 12 weeks. Without training, it offers little benefit1,2.
A striking finding is its effect on the brain. Several studies show that creatine improves memory in healthy adults. That effect is largest in people aged 66 to 76. In younger people aged 11 to 31, no difference was found. The brain requires a great deal of energy, and creatine acts as an energy reservoir in brain cells3,4.
For women after menopause, creatine is especially relevant. Women naturally have 70 to 80 percent less creatine in their muscles than men, and after menopause the loss of muscle and bone accelerates. A higher dose of 0.3 grams per kilogram of body weight per day, combined with resistance training, appears to slow that process. Effects on bone density are promising, but you likely need at least one year before they become measurable5.
A small study in 36 women around the time of menopause showed that even a lower dose of creatine (1500 mg per day, 8 weeks) improved reaction time and raised creatine levels in the brain, without serious side effects. However, the study is very small, so these are preliminary findings6.
Several studies in older adults report no serious side effects from creatine monohydrate1,2. It is worth noting that some authors of positive review studies have ties to creatine manufacturers, which may colour the results. For people with a physical disability, such as a spinal cord injury, the evidence is conflicting and too limited to support recommendations7.
Based on multiple review studies and controlled studies (PMID 30762623, 33800439, 35984306, 40673730, 40971619, 40854087, 34208239). The strength of evidence ranges from moderate (muscle and memory effects in older adults) to limited (small study in women around the time of menopause, para-athletes). Possible conflicts of interest with creatine manufacturers have been identified for some authors of the review studies.
Does creatine speed up muscle recovery?
Creatine (3-5 g/day) can likely speed up muscle recovery after intense training and improve strength and muscle mass, but for the recovery effect specifically the research findings are not fully consistent.
What does creatine do for people over sixty?
For people over sixty, creatine has reasonably well-supported benefits for muscle strength, muscle mass, and memory, especially when combined with resistance training. The usual dose of 3 to 5 grams per day is safe for healthy kidneys.
Does creatine work better with carbohydrates?
Carbohydrates likely increase the uptake of creatine into the muscles, but whether this also leads to better performance is not demonstrated by randomised research. Add carbohydrates if you want to load, but do not automatically count on extra training results.
Does creatine help prevent muscle loss with GLP-1 medications like Ozempic?
Whether creatine genuinely helps preserve muscle during GLP-1 medication use is unknown, because it has never been directly studied. Resistance training and adequate protein intake remain the only approach with any supporting evidence.
Does creatine also help with memory and concentration?
Creatine has the strongest evidence for a memory effect in older adults aged 66 and over. In younger, healthy adults, the best available research shows no convincing benefit.
How does creatine improve mood and wellbeing?
Creatine does not demonstrably improve mood in healthy people without additional stressors; as a supplement during sleep deprivation, on a vegan diet, or as an addition to antidepressants there are early positive signals, but these are still too limited to recommend creatine as a mood-enhancing agent.
