Creatine But Not Betaine Supplementation Increases Muscle Phosphorylcreatine Content And Strength Performance

Supplementation of 2g betaine over the course of 10 days to otherwise healthy adult men (sedentary) failed to increase phosphocreatine content in muscle tissue and failed to augment the creatine induced increase when 2g of betaine was added to 20g creatine.
