Supplementation of 2.5g TMG with 500mL gatorade in resistance trained men for two weeks appears to (in a fasted condition following a final 1.25g dose) increase work volume conducted on the bench press during the workout by 6.5%, although the increase of reps during any particular set or maximal power output were not affected.

The increase in lactate production seen in placebo (270%) was attenuated with betaine (210%), but lipid peroxidation (MDA) and nitric oxide (assessed by NOx) were unaffected.
