Supplement Research Update: Betaine Builds Muscle


Betaine increases muscle mass and decreases body fat in trained lifters

One of the first studies to report impressive gains in strength and power with betaine supplementation came from my old lab at the University of Connecticut. And since then there have been numerous studies confirming that betaine can in fact boost strength and power. This is the reason that I have long recommended taking betaine before and after workouts and why I included it in my Pre JYM and Post JYM formulas.

The latest study on betaine comes from the College of Springfield in Massachusetts.

Researchers had weight-trained males follow an undulating periodized weight-training program for six weeks. One group supplemented with 1.25 grams of betaine twice a day and the other group supplemented with a placebo twice a day.

They reported in a 2013 issue of the Journal of The... Subscribe to read more!
