Effects of Betaine Supplementation on Strength and Muscle Creatine Content

Not Applicable

Completed

• Conditions: Healthy Subjects

• Registration Number: NCT01213719
• Lead Sponsor: University of Sao Paulo

Brief Summary

It has been suggested that betaine supplementation may improve muscle strength by increasing muscle creatine content. However, there is no data supporting this assumption. The investigators speculate that betaine supplementation could enhance intramuscular creatine content, which would result in strength improvements.
