Human Growth Hormone, or HGH can be produced naturally through the pituitary gland in your body. HGH is responsible for cell growth and regeneration; increasing your muscle growth and bone density is not possible without this hormone. In addition, HGH plays a vital role in maintaining health of all human tissue, including the brain and other important organs. Recent studies have found that it also improves your sleeping patterns, and helps in the metabolism of body fat and its conversion to energy sources, which helps battle weight gain and even obesity.
When HGH is secreted it remains active in the blood for only a few minutes, but it is enough time for the liver to convert it into growth factors, the most crucial is insulin-like growth, which boasts several anabolic properties that promote muscle growth. In addition to increased muscle growth, HGH helps regulate body temperature, sugar and fat metabolism, and possibly even heart function. The pituitary gland puts out this hormone in bursts; levels rise following exercise, trauma, and sleep. However, scientists have found that HGH production rised during childhood, peaks during puberty, and then continues to decline as you age.
