Glutamine is the most abundant amino acid in the body. Total body glutamine levels are in the 100,000 mg level. To give you an idea of how abundant this amino acid is, try to give this some thought: in a healthy person, glutamine levels in the blood are three to four times greater than all amino acids.
What this means is that it is a source of fuel and energy for your body. It is particularly concentrated in the brain, skeletal muscles, stomach lining, lungs, heart, kidneys and liver.
Because of this critical distinction, glutamine is arguably the most important in the process of building muscle and gaining strength. It is found in natural food sources such as beans, beef, pork, poultry, fish, dairy products, raw parsley, raw spinach and cabbage.
Throughout intense physical activity, glutamine levels dramatically decline. This results in decreased recovery time.
Because of its ability to prevent muscle breakdown, provide nitrogen balance and enhance muscle recovery, this amino acid is also an ideal night time supplement. These qualities eventually pave the way for effective muscle building.
Since the body goes several hours without nutrients whilst an individual is asleep, consuming this supplement before bedtime will minimise muscle loss. Aside from this, it will also keep muscle tissue intact and boost the immune system as well.
In addition, taking glutamine before retiring at night will boost human growth hormone (HGH) release. Some studies reveal that it produces this effect in as little as 90 minutes after consumption. A 1995 study conducted by the Louisiana State University or LSU attributed glutamine’s ability to increase growth hormone levels because of its ability to indirectly stimulate arginine production in the kidneys.
Ideal dosage would be roughly ten grams daily—five grams post-workout and another five grams before sleeping.
