Natural Human Growth Hormone
Read our comprehensive reviews on Hgh and Anti aging products here.
Natural human growth hormone (HGH) is human growth hormone produced by the human pituitary gland, a gland located in the head below the brain. The hormone is regulated by other body processes and is released throughout life. Through childhood and into the early twenties, the hormone is responsible for regulating growth, and when growth is complete, at about age 21, the pituitary gland automatically begins to decrease the amount of HG that it releases into the bloodstream. The hormone remains important, however, and in normal individuals, there is always some HGH in the circulating blood, controlling numerous other metabolic and body processes.
There appears to be a direct correlation between the drop in HGH levels and the onset of certain subtle physical changes associated with aging. These include lower energy levels, increased fat storage, decreased muscle size and strength, as well as a higher risk for diseases such as heart disease, diabetes, osteoporosis, high cholesterol levels etc. Following this to a logical conclusion, there has been intense interest in recent years in the role in aging of natural human growth hormone and the possibility of reversing some age-related problems by increasing HGH levels in the blood.
When HGH therapy began, it was used for children with arrested growth due a deficiency of the hormone. At that time, natural human growth hormone was harvested from the pituitary glands of human cadavers and given to patients via injection. Today, we are able to produce HGH in the laboratory, so the grim and unsafe practice of getting it from human cadavers has been discontinued. HGH injections today, for all applications, contain synthetic HGH rather that natural human growth hormone.
Because of problems with legality, safety, and affordability of HGH injections, interest has returned to the advantages and possibilities for natural human growth hormone. Common approaches usually attempt to stimulate the aging pituitary gland to produce more of the hormone than usual. Dietary supplements are the usual way to go about this. There is compelling evidence that certain dietary factors stimulate the release of HGH into the circulation, and there is little doubt that these moderate and regulated releases can have benefits for health. Commercial supplements usually focus on amino acids, though other ingredients, such as extracts of animal hormone-producing glands and herbal extracts are sometimes included.
As long as supplements are obtained from a reputable producer and they contain moderate amounts of ingredients, rather than high doses, there is little danger of harm, and there can be some positive results after a period of time. As in all questions of health, however, we can never say enough about the benefits of a healthy life style - a good diet, regular exercise and plenty of rest will support the production of normal levels of natural human growth hormone by a healthy pituitary. If you suspect your diet is deficient, by all means add a supplement, but do focus on lifestyle in general. It can benefit you in so many ways.
