Structural differences exist between human, synthetic and animal hormones. In order for a replacement hormone to fully replicate the function of hormones which were originally naturally produced and present in the human body, the chemical structure must exactly match the original. There are significant differences between hormones that are natural to humans and synthetic or horse preparations. Side chains can be added to a naturally-occurring hormone to create a synthetic drug that can be patented by a manufacturer. Naturally-occurring substances can not be patented, so scientific studies are less numerous on natural hormones.
Natural hormones include estrone (E1), estradiol (E2), progesterone, testosterone, dehydroepiandrosterone (DHEA), and pregnenolone. Our compounding pharmacists work with patients and practitioners to provide customized hormone therapy that provides the needed hormones in the most appropriate strength and dosage form to meet each woman’s specific needs. Hormone therapy should be initiated carefully after a woman’s medical and family history has been reviewed. Every woman is unique and will respond to therapy in her own way. Close monitoring and adjustments are essential.
