Product Information

R1 Glutamine

Prolonged bouts of intense exercise don’t just drain your energy; they also deplete your body’s nutritional reserves and overcome its ability to recover. Case in point: glutamine. Overtraining can cause glutamine levels to drop, impairing performance. R1 Glutamine helps keep levels elevated.*

A very good option, it delivers what the brand promises and the fact that it's unflavored allows you to add it to any juice or smoothie.*

I advice this brand to everyone, they have long scoops that would help you till the end of the product. Some brands make short handled scoops so it is a pain when you reach the low levels of product, hard to reach the bottom of the can*
