What does creatine do for people over sixty?
Creatine has reasonably well-supported benefits for people over sixty in the areas of muscle strength, muscle mass and memory, especially in combination with strength training. A daily dose of 3 to 5 grams of creatine monohydrate is safe for healthy people.
Creatine is well supported for people over sixty: it helps you get stronger, maintain muscle mass and remember things better. The evidence is reasonably strong, especially when you combine it with strength training.
For muscle strength and lean mass, choose creatine monohydrate: listed on the label as 'creatine monohydrate', available as powder or capsules. Take 3 to 5 grams per day and keep that up for at least 12 weeks. A loading phase is not necessary; daily low doses work just as well. Whether you take it with or without carbohydrates makes no difference. More expensive forms such as HCl or citrate offer no proven advantage.
For memory you may also want to try it: studies in people aged 66 to 76 showed a clear improvement (SMD 0.88), while no effect was measured in younger adults. In that case take 5 grams per day for at least 4 to 8 weeks. Dose and duration do not appear to influence the effect in older adults.
For post-menopausal women there are indications that a higher dose, around 0.3 grams per kilogram of body weight per day, can also improve bone mass when combined with strength training. The evidence for this is still preliminary. Creatine is not worth your money if you buy it for fat loss, sleep or immune function: it has been too little studied for those purposes.
The fear that creatine damages your kidneys does not hold up at 3 to 5 grams per day for healthy people. If you have kidney disease or take medications that burden the kidneys, discuss this with your doctor first. There are also early indications of a beneficial effect on blood sugar metabolism in older adults, but that has been too little studied to draw conclusions from. Note: many research authors are advisers to or have been paid by Alzchem, the manufacturer of creatine.
All claims are based on multiple PMIDs, including a meta-analysis on memory (PMID 35984306), a meta-analysis on strength in adults (PMID 39519498), and several reviews specifically on older adults (PMID 40673730, 33557850, 33800439, 39720835). The evidence is predominantly of moderate quality; the glucose claim is limited (limited/associational).
Does creatine also help ordinary people, not just athletes?
Creatine is not just for athletes. Combined with strength training, it helps older adults gain more muscle strength, and probably also supports better memory.
What is the best way to use creatine?
Creatine works best in combination with strength training: optionally start with a loading phase of 20 grams per day for 5 days and then maintain with 2 to 5 grams per day. If you have a kidney condition, discuss it with your doctor first.
Does creatine speed up muscle recovery?
Creatine (3 to 5 grams per day) can probably 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.
How many grams of creatine per day is worthwhile?
For muscle strength and explosive performance, 3 to 5 grams of creatine monohydrate per day has a clear effect; a loading phase is convenient but not obligatory. For other goals the evidence is thinner, but safety for healthy adults is reasonably well supported.
What does creatine do in your body besides building muscle?
Creatine does more in the brain than in the muscles: it buffers energy and protects the brain against stress such as sleep deprivation. For healthy people, however, the effect on cognitive ability is small and most visible under pressure, not at rest.
How does creatine improve mood and wellbeing?
Small studies occasionally show positive signals in depression, but an international guideline based on many studies concludes that the evidence for creatine in mood and wellbeing is currently insufficient.
