L-carnitine (LC): the most widely available and least expensive L-acetylcarnitine (LAC): this form of carnitine appears to be the one to use for Alzheimer's disease and other brain disorders L-propionylcarnitine (LPC): this form of carnitine appears to be most effective for chest pain and related heart problems, as well as peripheral vascular disease (PVD)

Carnitine has direct/indirect modulatory effects on several physiological systems, such as the neural system [1]

During low to moderate exercise, L-carnitine supplementation was shown to save the muscles glycogen and instead stimulate fatty acid oxidation leading to higher energy production and loss of body weight 2

The authors of the present study propose that GPLC provides theoretical advantages by way of replenishment of carnitine stores which generally decline during stressful exercise and the inclusion of an additional energy source, via characteristics that are unique to this molecularly bonded form of carnitine
