The terms "bioidentical" and "synthetic" can be confusing when it comes to hormones. Bioidentical hormones are structurally identical to the hormones naturally produced in the human body. They have the same molecular structure as the hormones produced by the ovaries, testes, and adrenal glands. Synthetic hormones, on the other hand, have a different molecular structure than human hormones.
Bioidentical hormones are not technically synthetic, even though they are created in a lab. The term "synthetic" means that a substance is artificially made by combining chemical ingredients. Synthetic hormones are created by altering the molecular structure of a natural hormone in order to create a new compound. Bioidentical hormones have the exact same molecular structure as natural hormones - they are not altered or synthetic.
There are two main ways that bioidentical hormones are produced:
- Extraction and purification from plants or animal sources. Certain hormones, like estradiol and progesterone, can be extracted and purified from yams and soy plants. This process removes any impurities, leaving just the bioidentical hormone.
- Laboratory synthesis. Using compounds derived from yams or soy, the exact molecular structure of human hormones like estradiol, progesterone, and testosterone can be reproduced in the lab. This creates a product that is 100% bioidentical to hormones produced in the body.
While bioidentical hormones are not technically synthetic, the term "natural hormones" does not quite fit either. Some people believe bioidentical hormones should be called "natural" since they have the same structure as endogenous hormones. However, since they undergo processing and manufacturing, they are not strictly natural. "Bioidentical" is the most accurate term reflecting how these hormones are replicated.
There are significant differences between bioidentical and synthetic hormones in terms of their effects on the body:
- Bioidentical hormones have a more balanced, normal effect since they are structurally identical to endogenous hormones. Synthetic hormones often create hormone imbalances.
- Synthetic hormones have different side effects and risks. For example, synthetic progestins carry risks like blood clots and breast cancer. Bioidentical progesterone does not share these risks.
- Bioidentical hormones are dosed and balanced by physicians based on a person's needs. Synthetic hormones are one-size-fits-all.
- Many synthetic hormone preparations provide 15-25x the amount of hormones naturally found in the body. This can lead to hormone imbalances. Bioidentical hormones attempt to reproduce natural hormone levels and ratios.
- Synthetic hormones may not relieve menopausal symptoms as effectively as bioidenticals for some women. One study found that bioidentical hormones improved menopause symptoms better than a synthetic hormone medication.
In summary, bioidentical hormones are not technically synthetic even though they are artificially manufactured. Due to their identical molecular structure to endogenous hormones, they are considered bioidentical. They have advantages over synthetic hormones in terms of their balanced effects on the body.
