Hormones are an essential part of the metabolic process of living. Hormones are important for the cells, organs and metabolism. Our hormones decline through aging, menopause, disease or trauma. When this happens, we begin an accelerated aging process. Loss of hormones is one of the major reasons for our deterioration as we get older, both physically and mentally. Hormones are beneficial at any age, but the best long term protective benefits are achieved if hormones are replaced when you begin to lose them, usually in our forties.
