A recent study found that creatine supplementation can raise brain energy levels and slow cognitive decline in early Alzheimer's patients by 30%. Creatine is a widely used supplement that has been shown to have benefits for brain function, particularly in situations of high metabolic demand. The study suggests that creatine may be a useful adjunct for depression treatment and may also have benefits for healthy adults, particularly under conditions of metabolic stress. The findings have implications for the use of creatine as a therapeutic agent for neurodegenerative diseases.
