What Exactly Are Hormones?
Hormones are our body’s chemical messengers. Some of the more familiar hormones are insulin, testosterone, estrogen, cortisol, human growth hormone (HGH), progesterone and thyroid hormones. They are released by specific glands and travel in the blood to the places where they do their work. Once hormones are released into the bloodstream they travel to particular target cells to deliver their chemical messages and cause a specific biological response. Hormones affect all aspects of body function including growth and development, tissue repair and regeneration, metabolism, reproduction and even well-being. Hormones exist in a delicate balance and work within the cells accurately and reliably. But hormone imbalances become increasingly common with age and the link between declining hormones and the subsequent decline in our vitality, vigor and quality of life is well known.
