Supplementation of betaine at 2.5g daily for two weeks in recreationally active men failed to increase eccentric and concentretic power output in otherwise healthy subjects, and while there was no overall differences in fatigue the increase in fatigue during the workout appears to be minorly attenuated with betaine supplementation.

In active college aged men given betaine supplementation at 2.5g daily for a period of two weeks, there were no improvements in power output assessed by wingate, bench throw or squat jump but when promoted to exercise to fatigue (90% of 1RM on bench or squat) but did not benefit bench press performance. There were no differences in perceived fatigue nor soreness between groups.
