Daily supplementation with 2 g of L-carnitine from Lonza’s (Basel, Switzerland) Carnipure tartrate may elevate post-exercise recovery and reduce muscle soreness in middle-aged men and women, researchers have found.

Daily supplementation with 2 g of L-carnitine from Lonza’s (Basel, Switzerland) Carnipure tartrate may elevate post-exercise recovery and reduce muscle soreness in middle-aged men and women, researchers have found.
The double-blind, placebo-controlled, balanced crossover study was performed on nine men and nine women. Subjects were administered supplementation for three weeks, followed by a one-week washout period and then a three-week counterbalanced treatment. After the end of each three-week treatment period, subjects performed resistance exercises. Subjects also continued supplementation during the crossover period and after the study, so that recovery could be judged. Blood samples were also obtained pre- and post-exercise.
The researchers found that supplementation had significantly positive effects on purine metabolism, free-radical formation, muscle tissue disruption, and muscle soreness after physical exertion. However, markers of physical performance, such as strength, were not affected by supplementation.
The researchers concluded that L-carnitine may reduce chemical damage to tissues after exercise and optimize muscle tissue repair.
