Human Growth Hormone and Aging

HGH and the Aging Process

HGH Decreases As We Age

Human growth hormone (HGH or GH) is one of our most important hormones. It is the body's main growth and repair hormone. Its production is highest during the growth and development stage of childhood and adolescence. If children have a deficiency their physical development can be delayed and if they have too much they can grow more than normal.

Once adulthood is reached growth hormone is still needed because it plays a major role in the new cell growth that is required in order for the body to be able to heal itself.

The pituitary gland does continue to produce HGH after the growth and development stage has ended, however, by age 25 the amount released into the bloodstream is already on the decline, and as age continues to progress less and less is released. This growing lack of human growth hormone plays a major role in bringing on the effects of aging.

The Need to Restore Growth Hormone Levels

Growth hormone deficiency in the adult body is referred to as "SDS", or Somatotropin Deficiency Syndrome. Another term that is used is Somatopause.

Modern mainstream Western medicine has long known that restoring the levels of certain declining hormones can improve health and reduce the symptoms of aging. They have supplemented insulin, thyroid, estrogen, progesterone, and testosterone for years, however they considered the decrease of growth hormone in the aging body as unimportant. The general thinking has been that HGH is only needed during the growth and development stage of life and unfortunately some doctors still believe this to be true.

We in functional and anti-aging medicine know that growth hormone remains important throughout life and so it should also be restored in order to sustain optimal health.

The Growth Hormone Evidence is Clear

Studies done over the past 30 years have shown that improving growth hormone to a more youthful level can not only slow the effects of aging but may reverse some of the symptoms of aging that have already occurred.

A group of researchers headed by Jens Sandahl Christiansen of Aarhus Kommunehospital in Denmark sums up just how ubiquitous the effects of low human growth hormone in the body are:

"Untreated human growth hormone deficient adults have been shown to have increased cardiovascular mortality, reduced exercise capacity, reduced muscle strength, subnormal glomerular filtration rate and renal plasma flow, defective sweat secretion and defective thermo-regulation, reduced energy expenditure and basal metabolic rate, abnormal thyroid hormone metabolism, reduced myocardial function and clinical signs of premature atherosclerosis."1

The researchers found that the body composition of growth hormone deficient individuals was abnormal with increased fat mass, decreased lean body mass, decreased muscle/fat ratio, visceral obesity, reduced extracellular fluid volume and reduced bone mineral content. Furthermore, two independent groups reported impaired psychological well-being as compared to treated subjects with normal GH levels.1

The effects of decreased growth hormone are not as immediately dramatic as some hormones. For instance, a sudden drop in insulin is an acute condition that can be life threatening. The slow decline of GH over the years causes the body to wear out and break down.

Restoring HGH to a More Healthy Level Has Been Shown to:

Increase lean muscle
Improve metabolism
Decrease fat
Increase energy and stamina
Increase libido and sexual function
Improve bone density
Strengthen the immune system
Strengthen the heart, liver, lungs and kidneys
Decrease and balance blood pressure and cholesterol
Improve skin texture, elasticity, thickness, and moisture
Decrease wrinkles
Improve hair condition and growth
Decrease the amount of gray hair, increase youthful hair color
and more

How to Increase Growth Hormone in the Body

Replacement therapy with synthetic somatropin (GH) injections is very expensive and more importantly we do not know the full effects of replacing the body's naturally made hormone with an artificial one. These are reasons why some believe the injections should only be given as the last option.

Luckily, injections are not the only way in which GH may be improved in the body. We can take products that contain human growth hormone in homeopathic form and also help the pituitary gland to improve its own release of growth hormone. See our growth hormone supplements.

Anti-Aging and the Future

This is a great time in health research and development in that we are learning how to intervene in the aging process and restore many of the aspects of our youth. In anti-aging medicine studies are showing that we should be able to improve our resistance to disease, reverse and slow many of the effects and diseases associated with aging, improve our quality of life, and extend our life span.

We already know that by restoring certain hormones to a more healthy level we can help to recover our health, our vigor, our looks, and our sexuality. Thanks to ongoing cutting edge anti-aging research we now believe that the fountain of youth lies within our own cells, we just need to learn how to access and utilize it.

Besides our HGH supplements we are pleased to also offer a supplement that supports two very important anti-aging areas of focus, which are the lengthening of the telomeres and the repair of the DNA structure. See our Telomere/DNA supplement.
