Since declining hormone levels are associated with the aging process, restoring optimal hormone levels are key to peak performance, a sense of well being, and youthful appearance. Only natural hormones are used to replace the low levels found. Also, they are measured to balance the proper amount that the patients need. Some of these hormones are natural thyroid, progesterone, hydrocortisone, and estrogen, just to name a few. They must be balanced, one with the other, to create a feeling of well being.
