Human growth hormone (HGH) is the hypothalamic hormone produced by the anterior pituitary gland. Alternative name of the HGH is somatropin. It plays an important role in metabolism, increasing the mass, reducing the amount of body fat and doing a lot of everything else.
Growth hormone stimulates liver cells to release polypeptide ferments known as somatomedins. At the moment, the most studied HGH is insulin-like growth factor-1 (IGF-1). HGH and IGF-1 affect all body systems, that include but not limited by:
- Promote muscle development,
- Connect tissues, increase linear growth and restore the body,
- Make the structure of the skeleton stronger,
- Regulate various functions related to the metabolism,
- Contribute to normalization on cognitive functions,
- Promotes the health of the heart.
The secretion of human growth hormone slows down with age. It stabilizes in youth and after 18-25 years the hGH secretion levels by the pituitary gland decreases by 50% every 7 years. The level of IGF-1 decreases gradually in the same time. This leads to a number of unpleasant symptoms, usually linked with aging processes.
- Accumulation of fat,
- Decrease in muscle mass,
- Disturbance of cognitive functions (memory, alertness),
- Decrease in strength and stamina,
- Increased bone fragility,
- Sleep disorders.
