Glutamine Peptides have been shown to be absorbed 250 times faster, and are more bio-available than standard "L - Form" of glutamine powder.
Studies have shown that strenuous exercise and trauma are linked to a drop in plasma glutamine levels and impaired immune function. Supplementing with glutamine peptides may help maintain muscle mass, help the immune system and improve physical performance.
During times of stress, the body experiences an increase in free radicals, resulting in a decrease in the number of antioxidants to fight them. Studies have shown that increased plasma levels of glutamine can reduce the rise of free radicals, which decreases the risk of infection or stressed induced illness.
Peptide technology is slowly making its way into the exercise, CrossFit, powerlifting, and bodybuilding circles. However, most individuals are still on the fence about their efficacy or what peptides actually do. Athletes that are currently taking peptides are literally posting huge gains from size, strength, and stamina. Peptide bound amino acids are considered to be the “best thing to hit the market since creatine monohydrate.” Peptides are not stimulants, it’s not a performance enhancing drug, and they can be taken by all athletes. So what is a peptide bound amino acid? Peptide technology binds other amino acids to the target amino forming a peptide bond. This makes it more stable and highly assimilated by the body. Regular amino acids are considered “free form” aminos. This means that the amino acid is "free" from being bound to other amino acids. Free form aminos are less stable and you have to take a handful at a time in order for them to be effective.
Free form l-glutamine only affects the muscle tissue slightly. Glutamine peptides actually heal muscle tissue and the peptide bond allows it to avoid a competitive amino acid environment. During intense exercise, blood and muscle levels of glutamine tend to fall. Supplementing with glutamine peptides before and after training can help the body maintain steady levels of glutamine in blood and muscle tissue. This can lead to protein synthesis and an increase in muscle mass.
Glutamine is responsible for transporting nitrogen into muscles cells, it has anti-catabolic factors and growth hormone elevating effects. Glutamine peptides not only help with recovery, but they also help your gut and immune system. The cells in your intestinal tract and immune system tend to divide rapidly and consume a lot of energy, which ultimately comes from glutamine. Without glutamine, your body would suffer intestinal wasting and the immune system becomes weak.
This may be a factor in why people tend to get sick when they over train. The factors that do deplete glutamine stores are trauma, surgery, disease, stress and intense training. Lastly, a recent research article published in July of 2014 in Nutrition states that supplementing L- Glutamine in the diet may help with weight loss and type 2 diabetes managment. The Pilot study showed that type 2 diabetic patients have significantly lower concentration of amino acid glutamine circulating in the body. The subject group showed that consuming 30g/d of glutamine following each main meal helped reduce blood glucose levels as well as body fat, waist lines, and systolic blood pressure to some extent.
