Aging is an accumulation of damage to macromolecules, cells, tissues and organs.Much of life extension has been concerned with the use of nutrition, in the form of diets or supplements, to extend lifespan.
The idea that antioxidant supplements, such as Vitamin C, Vitamin E, lipoic acid and N-acetylcysteine, might extend human life stems from the free radical theory of aging.
Human Growth Hormone (HGH) is widely regarded as one of the most important hormones in the human body. HGH is commonly associated with the aging process and the many resulting conditions we experience as we age.
HGH is responsible for stimulating the growth of our tissues. Growth in our internal organs, skin, muscles, nerves, and bones is stimulated by levels of HGH. As levels of HGH slow down as we get older, we also slow down.
HGH is produced naturally, in everyone, by the pituitary gland. After the age of 23, your natural HGH levels begin to decline and you may start to experience the affects of aging. This includes weight gain, decrease in energy, lack of sex drive, low endurance, muscle atrophy and more.
With higher HGH levels, improved elasticity of the skin occurs, as well as strengthened nails, and enhanced skin rejuvenation.
One of the main ingredients in all the HGH releasing products mentioned is
L-Arginine
. L-Arginine is involved with the production of new skin and connective tissue. It is essential to the formation of collagen and boasts many benefits that relate to skin repair and rejuvenation.
