Breakthrough findings in glutamine absorption prompt a revolutionary invention. MHP Glutamine-SR is a breakthrough in Glutamine Absorption allowing 300% greater absorption. Time release formula insures distribution to muscle tissue over a 12 hour. Glutamine-SR is the most bio-efficient and powerful Glutamine supplement in the world. The Micro-Feed Technology also increases bio-availability and utilization of L-Glutamine by providing a controlled steady supply for 12 straight hours. This constant supply and replenishment of Glutamine will keep you in an anabolic muscle building state and 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 and powerful Glutamine supplement in the world.
