Acetyl-L-Carnitine
The amino acid acetyl-L-carnitine is produced by your body naturally. It is crucial to your metabolism, especially for the production of energy. Acetyl-L-carnitine supplements are believed to increase mental alertness, enhance memory, and prevent age-related memory decline.
Supplemental acetyl-L-carnitine has been found in some animal studies to improve learning capacity and delay age-related decline in brain function. Studies on people have revealed that it could be a helpful supplement for preventing the age-related decline in brain function. Additionally, it could help those with mild dementia or Alzheimer's disease improve their brain function. However, there is little evidence to support its beneficial effects on other healthy people who are not experiencing a loss of brain function.
