The ability of the human body to produce hormones can decline and become imbalanced with age. Surgical procedures and long periods of stress can cause hormones to become unstable as well. However, the body’s need for hormones still remains. Hormone replacement can be used to help maintain the proper functioning of the body. Bio-Identical Hormone Replacement Therapy or BHRT can restore a hormone balance through the use of plant-derived hormone precursors that have been modified to become structurally identical to what the human body makes. These hormones include estrogens, progesterone, and the androgens (i.e. testosterone and DHEA). Each hormone has a multitude of functions in the body. Some of these include helping with memory, promoting weight loss/gain, improving sleep, increasing energy levels, raising libido, regulating body temperature, and maintaining moisture of the skin. Finding the right balance of these hormones is essential for optimal benefits.
