New Role for Glutamine in Protein Synthesis? Study Suggests Direct Effects on Mammalian Target of Rapamycin (mTOR) - EAAs Alone Won't Produce Optimal Results

Image 1 ( Pumping Iron ): The guy in the middle, obviously no one else than the Austrian Oak, took glutamine, the rest of the guys forgot about it in all the craze about leucine... no, just kiddin' ;-) Still, someone who trains like Arnold, is probably most likely to benefit from additional l-glutamine After all those bad news about allegedly effective supplements, I thought it may be about time to present some good news about an allegedly ineffective supplement: Glutamine!

A recent study by scientists from Australia ( Pal. 2010 ) suggests that it may not be necessary, yet beneficial. Figure 1: Changes in body weight (A); BMI (B); % body fat (C) and waist circumference (D). From left to right: Control, FIB, HLT, HLT-FIB Studying a cohort of 72 overweight and obese individuals with a BMI between 25 and 40 kg/m 2 and age between 18 and 65 years, the researchers found that over a time period of 12 weeks in which the subjects either practiced their "normal" eating habits or changed to a healthy food diet (HFT), supplemented with fiber (FIB) or switched to a healthy food diet that was supplemented with fiber (HFT-FIB)... [...] weight, BMI and % total body fat were significantly reduced in FIB...
