The acetyl group of acetyl l carnitine is used to form acetyl-CoA, the most important intermediary in the generation of energy from amino acids, fats, and carbohydrates.
In conclusion, acetyl L carnitine and L-carnitine were similar in increasing ambulatory activity in old rats and elevating carnitine levels in blood and brain.
To compare the efficacy of Acetyl carnitine with that of amantadine, one of the drugs most widely used to treat MS-related fatigue, 36 MS patients presenting fatigue were enrolled in a randomised, double-blind, crossover study.
