Gen-Tec Nutraceuticals source, blend and package the highest quality laboratory tested (HPLC) Micronized L-Glutamine powder. Our L-Glutamine is naturally fermented from seed and glucose using a patented 18 stage extraction and filtration process. Glutamine 320 is virtually impurity free and micronized to 320 mesh size making it finer in texture to improve mixing and absorption. Gen-Tec Nutrition source and blend the highest quality pharmaceutical grade L-Glutamine. We are privy to possibly the world's finest 320 mesh' size free form powdered L-Glutamine. We can also boast the lowest impurity content of our naturally derived L-Glutamine product. These two factors contribute to bioavailability and absorption (not solubility in water). L-Glutamine requires no carriers to enter the bloodstream or muscle cells. L-Glutamine is the most abundant amino acid in muscle tissue comprising about 60 percent of the free amino acids in the blood and muscles. It is also very abundant in the immune system.

L-Glutamine stores are depleted dramatically during any form of high intensity training ( weight training, cycling, running etc.) through the "glucose alanine cycle". This in turn, decreases strength, stamina and recovery. Supplementation with L-Glutamine helps restore levels in muscle, providing an anabolic environment and muscle growth. Available in 1 kg jar.
