Breakthrough findings in glutamine absorption prompt a revolutionary invention. MHP's Glutamine-SR is a breakthrough in glutamine absorption allowing 300% greater absorption. Time release formula insures distribution to muscle tissue over a 12 hour period. Glutamine-SR is the most bio-efficient & powerful Glutamine supplement in the world. The Micro-Feed Technology also increases bio-availability & utilization of L-Glutamine by providing a controlled steady supply for 12 straight hours. This constant supply & replenishment of Glutamine will keep you in an anabolic muscle building state & prevent catabolism. Glutamine-SR's 12 Hour Sustained Release Micro-Feed Technology has raised the standards in glutamine supplementation, making Glutamine-SR the most bio-efficient & powerful Glutamine supplement in the world.• 60% of your muscle tissue is made up of Glutamine. Strenuous exercise depletes Glutamine stores at a faster rate than they can be replenished• 70% of the regular Glutamine powder you consume is utilized by the stomach & the intestines, leaving only 30% available to feed muscle tissue• 90% of ingested Glutamine is utilized in 1 hour, leaving you in a catabolic (muscle wasting state) Based on these facts, the Glutamine you are taking right now is not providing the anabolic muscle building environment needed to build rock hard muscle & improve recovery. 70% of it never reaches muscle tissue & 90% of it is gone in 1 hour, leaving you with a low dosed short supply of Glutamine. The end result is very little anabolic activity & can actually lead to catabolic muscle wasting because you're relying on your glutamine supplement to supply & replenish the glutamine needed & it just isn't delivering.
