Gaba
GABA has the ability to reduce the level of cortisol in our body, thus preventing the onset of catabolic processes. As one of the most important neurotransmitters, GABA inhibits or slows down the transmission of nerve impulses from one cell to another in the areas of the brain responsible for the occurrence of states of anxiety and fear, thereby having a relaxing effect.
Although it is produced by our body from glutamic acid, this ability worsens with age, which makes it necessary to replenish its reserves through sports nutrition based on it.
More information about GABA
Gamma-aminobutyric acid, or GABA, is the so-called biogenic amine of glutamic acid, i.e. it is a natural substance. GABA has its main effect in the brain.
GABA is the growth hormone activator 
By naturally stimulating the anterior pituitary lobes, GABA increases the amount of growth hormone produced and improves the body's ability to build muscle.
Many people know that the growth hormone, along with testosterone and insulin, is one of the most powerful anabolic hormones that directly affect muscle growth. Moreover, it is able to simultaneously reduce fat reserves, increasing lipolysis, and make muscles grow.
In simple terms, growth hormone makes us look younger, soothes our skin, creates conditions for the growth of our muscles, strengthens our bones, burns excess fat, and supports the immune system.
Unfortunately, after the age of 20, the production of this valuable hormone gradually decreases, and it becomes more difficult to gain muscle mass and increase strength. It is precisely because of this situation that GABA-based products have appeared in sportsnutrition since they allow our body to produce a sufficient amount of its own growth hormone and not suffer from the consequences of its deficiency while maintaining itself in good physical shape.
An increase in growth hormone levels from taking GABA can reach 500%
Various studies show the effectiveness of GABA. One study, conducted in Italy, found a five-fold increase in growth hormone levels in test participants 90 minutes after taking GABA.
The study involved 19 people who received 5 g of GABA orally and a placebo group. As a result, the control group showed a 500 percent increase in growth hormone levels compared to the placebo group and its pre-trial levels.
In addition, these experiments have shown that adding 2 g of GABA to the diet is enough to get the desired effect from its consumption.
