l-carnitine orotate L-Carnitine (tartrate)

Creatine not only provides more strength and endurance, but also reduces muscle damage, thus

Vegans and vegetarians have a significantly reduced capacity to synthesize TMAO from carnitine, which may explain the cardiovascular health benefits of these diets. The scientists also suggested that people might want to think twice before taking carnitine, calling for further research into the safety of the dietary supplement

Two longer term studies undertaken in recreational athletes (1.4-3g L-carnitine daily for 12-24 weeks) showed increases in muscle carnitine concentration were possible provided a sufficient amount of carbohydrate (80g) was consumed with each dose of L-carnitine
