Additional research needs to be conducted to further explore the potential benefits of betaine on mood. In conclusion, two-weeks of betaine supplementation in active, college males appeared to improve muscle endurance of the squat exercise, and increase the quality of repetitions performed (e.g. number of repetitions performed at 90% of 1-RM). These performance improvements were realized within 7-days of supplementation. However, no changes in power performance were seen during this study. Additional research is warranted

to determine the rate of muscle creatine synthesis Selleck Vistusertib from betaine supplementation, and to compare muscle creatine synthesis kinetics from creatine supplementation versus betaine supplementation.
