GH Support, from Vitobest®, is a product designed to stimulate the production of growth hormone. It's composed of several amino acids, vitamins, and minerals and the synergy of its powerful combined formula, stimulates the formation of growth hormone.1.4.

What is the growth hormone?

Growth hormone is a neurohormone secreted by our pituitary gland. Its main function is the regeneration, reproduction, and growth. It also contributes to the development of body tissues and increases fat metabolism.

Throughout life, our body undergoes changes in the growth hormone secretion profile, Children and young adults are the ones who release the most growth hormone, especially during sleep hours.

As the years go by, the production of growth hormone decreases, promoting:

  • Loss of muscle and bone mass.
  • Increase in visceral fat.
  • Decrease in motor function.
  • Alterations in cognition (such as problems with concentration and memory).
  • Sleep disorders (which in turn negatively affect the endogenous production of growth hormone).

When is the growth hormone released?

This hormone is secreted by the pituitary gland. Most of the secretion of this hormone mainly occurs after the onset of an individual's sleep, especially during the sleep phase known as REM. At that moment is when the body releases the greatest amount of the hormone, repairing tissues that suffer wear and tear during bodily movements and mental activities.


GH Support 01


Active ingredients of GH Support from Vitobest®:

L-Arginine HCl.

L-Arginine is an essential amino acid and is a dipeptide formed by aspartate and arginine. It also stimulates the release of growth hormone (GH) from the pituitary gland.2. Studies have shown that people of all ages can show an increase in HGH levels if they supplement with L-Arginine. L-Arginine is also one of the precursors of creatine and is essential for the production of urea, necessary for the elimination of toxic ammonia from the body.3. GH Support, of Vitobest®, it incorporates L-Arginine in the form of hydrochloride salt (HCl), which is the highest quality form and also the most effective.

GABA (gamma-aminobutyric acid).

GABA contributes to reducing body fat levels and increasing muscle tissue, stimulating the brain to secrete a larger amount of human growth hormone (HGH). GABA was discovered in 1970 and subsequent studies showed that it was a potent neurotransmitter and a great enhancer of the effectiveness of growth hormone secretions in athletes. Studies show that GABA contributes to the release of growth hormone15.


GH Support 02

  • Immunoreactive growth hormone (irGH) (A) and immunofunctional GH (ifGH) (B) time-point concentrations for the rest-placebo (P), rest-GABA, exercise (EX)-P, and EX-GABA conditions. Data are the means ± SE. * EX-GABA is different from rest-P and rest-GABA (P ≤ 0.01); † EX-P is different from rest-P and rest-GABA (P ≤ 0.05); # EX-GABA is different from EX-P (P ≤ 0.05); ** EX-GABA is different from rest-P (P ≤ 0.01); § EX-P is different from rest-P (P ≤ 0.05).


Colostrum (Colexan®).

Colostrum is a liquid secreted only by mammals during pregnancy and the first few days after childbirth. Classified as highly nutritious, it contains a high concentration of immunoglobulins and other components of the immune system that protect the newborn from pathogens that can affect it. Among its main components are amino acids, immunoglobulins (especially IgG), and growth factors5, vitamins, cytokines, glycoproteins, lactoferrin and transferrin, proline-rich polypeptides (PRP), leukocytes, Lactobacillus acidophilus, enzymes, lysozymes and lymphokines, which makes it the ideal food to help keep the immune system in optimal condition.

The colostrum of GH Support, of Vitobest®, it is of the highest quality, specifically of Colexan®, which contains more than 35% of IgG (Colexan® Ultra Grade Colostrum Powder > 35% IgG), considered the best on the market.

  • Contains 3 times more PRP (proline-rich polypeptides)6 that the rest of the colostrums, and an immunoglobulin concentration of around 45% (35% IgG).
  • Provides transfer and growth factors4.
  • It is rich in growth factors IGF-I, IGF-2, TGF-β, IgG. IgG is an anabolic factor that enhances protein accumulation and is directly related to the release of growth hormone.7.


Tryptophan is an essential amino acid that acts as a precursor to serotonin, a neurotransmitter responsible for our mood, it helps to positively modulate stress. Tryptophan plays an important role in physical recovery and development9, this is because for the normal production of growth hormone (GH) it is necessary to achieve proper rest and sleep. Tryptophan promotes rest8, as it is also a precursor of melatonin, involved in the sleep-wake cycle, benefiting both the induction and maintenance of sleep, and sleep is a fundamental factor for the normal production of GH.


GH Support 03



Lysine is an essential amino acid. Studies show that it is more effective when combined with L-Arginine, and that it promotes the release of growth hormone13.


When combined with L-Arginine, it plays an important role in the metabolism of excess body fat11. This combination of amino acids stimulates the body's own production of human growth hormone (HGH)10.


It is a hormone that we naturally secrete from the pineal gland, a structure located in the central part of our brain. Its main role is to regulate day and night cycles12. Considering that the growth hormone is secreted while we sleep, melatonin may play an important role in its stimulation.

Bisglycinate of Magnesium (Albion™).

Magnesium contributes to the normal functioning of the nervous system and the release of growth hormone14.
