What are Bioidentical Hormones? 
Bio-identical hormones are custom-mixed formulas containing various hormones that are chemically identical to those naturally made by your body. These prescription and over-the-counter products are marketed as being tailored to a woman's individual hormone needs, typically determined through saliva hormone testing. Manufacturers claim that bio-identical hormones are safer than standard, FDA-approved hormone therapy.
