Studies with both ALCAR and L-carnitine have shown that they have potent nutrient repartitioning effects, and there are some studies indicating that L-carnitine can increase exercise performance. In one study, both young and old rats were supplemented with ALCAR and compared with age-matched controls. Nutrient partitioning and muscle mass and function were among the factors measured. Body weight did not differ significantly between the two groups, but there were strong differences in the fat to protein ratios. The young rats fed ALCAR had slightly higher body protein levels (not statistically significant) and significantly less body fat, while the old rats fed ALCAR had much high body protein levels and the same amount of body fat (1). ALCAR may be especially useful for older people, as one rat study found that long-term administration prevents the progressive increase in ...  more
