L-Glutamine is a real gem, with fantastic fitness applications as well as great nootropic benefits, a real two-in-one. L-Glutamine is a conditionally essential amino acid, serving as a protein building-block in our bodies, amongst many other critically important uses. L-Glutamine can raise human growth hormone (HGH) levels, lead to muscle gain, improved energy levels and an increase in resting metabolic rate. There is also evidence that it assists with reducing fatigue in-workout, and improving muscle recovery time after a workout. Long workouts have been shown to dramatically reduce levels in the body, making this a very useful post-exercise supplement. Our immune systems rely heavily on L-Glutamine as a critical fuel source for our immune cells. These include our intestinal cells, which use it during their normal growth and maintenance cycle. Our intestinal cells play a core role in our overall immune health. As a nootropic, Glutamine is the main precursor to the excitatory neurotransmitters glutamate and aspartate, and the inhibitory neurotransmitter GABA. Optimal glutamate and GABA levels positively affect alertness, focus, mood and memory. When you balance L-Glutamine levels in your brain, you feel calm and have a reduction in cravings for sugar and alcohol.
