L-Glutamine is also one of Secratatropin's ingredients.
L glutamine is the most abundant amino acid found in human muscle and plasma. Over 60% of the free-floating amino acid pool in skeletal muscle cells is made up of L glutamine. Glutamine is unique in that like glucose it is one of the preferred energy sources utilized by rapidly proliferating cells. It is a major fuel source for the brain and together with its relatives the stimulant neurotransmitter Glutamic acid and the inhibitory neurotransmitter GABA they form the most abundant amino group in the human brain.
It is also a primary nitrogen donor, meaning that it moves the nitrogen around in the body to where it is needed. Maintaining a positive nitrogen balance is absolutely necessary for muscle building.
It is released from the muscle during times of stress (such as hard weight training workouts) and dieting. This amino acid not only has been shown to be a great anti-catabolic agent (protects the muscle from the catabolic activities of the hormone cortisol), to be a contributor to muscle cell volume, and to have immune system enhancing properties but also to help in the following ways:
- Regulation of protein synthesis (this is one of the ways in which steroids exert their muscle building effects).
- Accelerating glycogen synthesis after a workout.
- Sparing the use of the glycogen stored in the muscle cell (recall that the glycogen stored in the muscle cell is what gives the cell the healthy volume and firmness that you seek).
- Faster recuperation from weight training workouts.
Natural sources of L-glutamine include beef, chicken, fish, eggs, milk, dairy products, wheat, cabbage, beets, beans, spinach, and parsley. Small amounts of free L-glutamine are also found in vegetable juices.
