Synthetic hormones are derived from plant progesterone and animal estrogens, but are not identical to the hormones your body uses (generally an extra covalent bonds or molecules are added so that it can be patented). Synthetic hormones act as toxins because their chemical makeup cannot be metabolized properly.
BodyLogicMD only uses natural bioidentical hormones. Unlike synthetic hormones, bioidentical hormones or natural hormones are replicas of the body’s own natural hormones. Bioidentical hormones made from soy, yams and other plant extracts, which are changed in a lab to be biologically identical to the same hormones your body makes.
