Important In Protein Metabolism, Cell Volumizing, And Anti-Catabolism!
谷氨酰胺是体内一种含量最多的游离氨基酸，以左旋的形式存在，同时也是一种"条件性必需"氨基酸，这就是说在一定条件下(如由于运动产生的肌肉紧张)训练后组织的修复和身体恢复会使谷氨酰胺变得"必需"(注：此时谷氨酰胺的合成速度不能满足机体需要，其必须作为膳食的一部分进行补充)。
L-谷氨酰胺在肌肉增长和修复过程中的每个阶段，都发挥非常重要的作用。打强度训练情况下自身谷氨酰胺合成不足，肌肉会分解肌肉蛋白满足机体对谷氨酰胺的需求。
对于健身者来说，补充左旋谷氨酰胺会带来以下好处：
- 保持骨骼肌蛋白质水平，减少肌肉分解。
- 提高机体免疫机能，维护免疫系统。
- 提高蛋白质合成
- 扩大骨骼肌细胞体积

For years athletes and bodybuilders have been looking for a product to help them recover faster from workouts and competition, keep their muscles well hydrated for maximum growth and provide numerous other benefits in the muscle building process. In recent years most athletes have to understand the benefits of L-Glutamine. Now further research into this topic suggests that the benefits may be greater than we had first thought.

L-Glutamine is the most abundant amino acid in the body and makes up more than 60% of the intramuscular amino acid pool. L-Glutamine plays an important role in many body functions such as proper immune system function, the transfer of nitrogen between organs, precursor to DNA and regulation of protein synthesis and degradation.
