Synthetic hormone therapy and natural hormone therapy are two approaches to hormone replacement therapy (HRT) used to treat hormonal imbalances or deficiencies such as menopause. Here are the key differences between them:
Source of Hormones
Synthetic Hormone Therapy: Uses hormones that are created in laboratories. These synthetic hormones are often designed to mimic the hormones naturally produced by the body, but their chemical structures may not be identical to natural hormones.
Natural Hormone Therapy: Also known as bioidentical hormone therapy (BHT), uses hormones that are derived from natural sources, such as plants (often soy or yams). These hormones are chemically identical to the ones produced by the human body.
Chemical Structure
Synthetic Hormones: May have slight variations in their chemical structure compared to natural human hormones. These variations can affect how the body metabolizes and responds to the hormones.
Natural (Bioidentical) Hormones: Have the same molecular structure as the hormones naturally produced by the human body, which can potentially lead to a more natural interaction and metabolism within the body.
Formulation and Regulation
Synthetic Hormones: Typically manufactured by pharmaceutical companies and are subject to strict regulatory oversight by agencies like the FDA (Food and Drug Administration). Common examples include synthetic estrogen and progestin.
Natural Hormones: Can be compounded individually by pharmacies to match specific needs of patients, which may not always undergo the same level of rigorous testing and standardization as synthetic hormones. Some bioidentical hormones are available in standardized forms and are also regulated by the FDA (The Food and Drug Administration).
Types of HRT and Dosing Administration
Synthetic Hormones: Available in various forms, including pills, patches, gels, injections, and creams. Examples include Premarin (conjugated estrogens) and Provera (medroxyprogesterone acetate).
Natural Hormones: Also available in multiple forms such as creams, gels, patches, and pills. Compounded bioidentical hormones are often tailored to individual prescriptions.
Efficacy and Safety
Synthetic Hormones: Have been studied extensively in clinical trials, providing a robust understanding of their benefits, risks, and side effects. They have a proven track record but may cause side effects due to their slightly different chemical structure.
Natural Hormones: Advocates claim they are more easily accepted by the body and cause fewer side effects due to their identical structure to human hormones. However, critics argue that there is less large-scale, long-term research on the efficacy and safety of compounded bioidentical hormones compared to synthetic ones.
Popularity and Use
Synthetic Hormones: Have been traditionally more widely used due to their availability, standardisation, and the extensive research supporting their use.
Natural Hormones: Have gained popularity in recent years, particularly among individuals seeking more "natural" treatment options and those who experience side effects with synthetic hormones.
The primary differences lie in the source and chemical structure of the hormones used, the level of regulatory oversight, and the form in which they are administered. Both types of therapy aim to achieve hormonal balance, but their suitability and effectiveness can vary based on individual needs and responses.
I personally prefer natural over synthetic hormones, however I'm an avid supporter of each to their own and everyone researching and using what best works for them, what makes them feel good and which one strikes the most balance.
Because that's what we're all searching for. Balance, peace and hormonal health.
