Creatine has not slowed Parkinson’s progression in large human trials, so it is not a standard treatment for the disease.

A single-ingredient powder can help raise muscle phosphocreatine, which may improve strength, power, and hard-effort training output.

Creatine is studied mostly in adults, and minors should get medical advice before using it for training.

Creatine may help short, hard exercise in adults, but routine use by children still gets a cautious answer.

Available human data on creatine while nursing is sparse, so most doctors advise caution unless there’s a clear medical need.

Human trials show the clearest gains in short, hard efforts, with modest water weight and a solid safety record in healthy adults.

Most adults take 3 to 5 grams of creatine a day, and a 20-gram loading phase for 5 to 7 days is optional.

For many adults on insulin, creatine is not automatically off-limits, yet kidney status, hydration, glucose trends, and ketones need a check first.

For many healthy older adults, creatine monohydrate is well tolerated at standard doses, though kidney disease calls for medical clearance.

Bloating, cramps, or nausea after a dose usually comes from too much powder at once, poor mixing, or taking it on an empty stomach.
