Glutamine-SR's Micro-Feed Technology allows for an unprecedented 100% of L-Glutamine utilization, maximizes anabolic/anti-catabolic effects and optimizes muscle growth and recovery. Research on leading brand supplemental L-Glutamine powder has shown that the stomach utilizes 70% of the amount ingested, leaving only 30% available for delivery to muscle tissue. The exclusive and patented Micro-Feed Technology used in Glutamine-SR protects the L-Glutamine as it is transported through the stomach and increases the amount delivered to muscle tissue. The Micro-Feed Technology also increases bio-availability and utilization of L-Glutamine by providing a controlled, steady supply for 12 straight hours. 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.
