May help with Parkinson’s disease

Parkinson's disease is distinguished by low levels of dopamine, a critical neurotransmitter in the brain. Dopamine deficiency results in brain cell death and a variety of significant symptoms such as tremors, loss of motor function, and speech problems. Creatine has been related to positive benefits in Parkinson's disease rats, averting 90% of the regular reduction in dopamine levels. There is no proof, however, that it has the same impact on people. Weight training is commonly used by Parkinson's patients to improve their loss of muscular function and strength.

Combining creatine with weight training increased strength and everyday function more than training alone in one trial of people with this illness. A recent review of five controlled studies in persons with Parkinson's disease found that ingesting 4-10 grams of creatine per day did not enhance their capacity to do everyday tasks appreciably.
