A clear, evidence-informed guide for people who want balanced energy, mood, sleep, and aging support
At La Mer Holistic Medicine, our approach is integrative: we look at the whole person—mind, body, and spirit—then create a plan that aligns your symptoms, history, labs, and goals. This guide explains how bio-identical hormones work, when they’re most helpful, and what to ask before starting.
What “bio-identical hormones” actually means
Important distinction:
Compounded “bio-identical” hormones are mixed by a compounding pharmacy and are not FDA-approved; professional medical organizations note concerns about dose consistency, purity, and marketing claims that outpace evidence.
Who may benefit (and who should be cautious)
Often-discussed symptom patterns:
Extra caution is warranted if you have a history of certain cancers, blood clots, unexplained vaginal bleeding, or complex cardiovascular risk factors—this is where personalized medical evaluation matters most.
“Natural” doesn’t mean “no side effects”
A key safety takeaway from major medical organizations: when FDA-approved options are available, there’s typically no evidence-based need to use compounded hormone formulations, and compounded products may have additional quality-control concerns. (support.endocrine.org)
Bio-identical hormones and “timing”: why your age and symptom timeline matter
In late 2025, the FDA announced it would remove a long-standing boxed warning from many hormone-based menopause treatments and update labeling to reflect newer evidence and individualized decision-making. (apnews.com)
Practically, this means a thoughtful evaluation (not a one-size-fits-all rule) is the best starting point—especially if your goal is symptom relief plus long-term healthy aging support.
Quick comparison table: FDA-approved vs. compounded “bio-identical” hormones
| Factor | FDA-approved bio-identical hormones | Compounded “bio-identical” hormones |
|---|---|---|
| Quality & dose consistency | Standardized manufacturing oversight | May vary in dose/purity; not FDA-approved |
| Evidence base | Studied for symptom relief and safety labeling | Limited high-quality evidence; safety/efficacy less certain |
| Marketing claims (“custom,” “saliva-based dosing”) | Dosing typically guided by clinical response + appropriate labs | Professional groups caution that saliva testing for dosing lacks support |
| When considered | Often first-line when hormone therapy is appropriate | May be considered when specific needs can’t be met with approved options |
| Bottom line | Preferred starting point for many patients | Use caution; ask detailed safety questions |
How to start bio-identical hormone therapy safely (step-by-step)
1) Get specific about your goals (not just your lab numbers)
Hormones are rarely the only factor. We clarify what you want to improve: sleep continuity, hot flashes, libido, mood stability, stamina, cognitive performance, or body composition. Your symptom pattern helps guide which hormones, delivery method, and dosing strategy are most appropriate.
2) Review medical history and risk factors
A careful intake matters: personal/family history, migraines, clotting risk, breast/uterine health, and current medications/supplements. This is where integrative medicine shines—because we’re not just “treating a lab.”
3) Choose the most appropriate form (route) for your body
Options may include topical/transdermal approaches, oral therapies, or localized vaginal therapies (when appropriate). The “best” option depends on symptoms, preferences, and safety profile.
4) Prioritize FDA-approved bio-identical options when possible
Because consistency and safety oversight matter, many patients do best starting with FDA-approved therapies when hormone therapy is indicated. (support.endocrine.org)
5) Reassess and fine-tune (this is where results get “natural”)
The goal is not to “maximize numbers.” The goal is to help you feel steady, clear, and well—without uncomfortable side effects. Follow-ups help refine dosing and timing, and we also check whether sleep, stress physiology, nutrition, and movement need stronger support.

FAQ: Bio-identical hormones
Not automatically. “Bio-identical” describes the hormone’s structure, not the risk level. Many FDA-approved hormone therapies are already bio-identical. Safety depends on your personal risk factors, the dose, the route, and timing.
FDA-approved products are standardized and regulated for consistent dosing and manufacturing quality. Compounded products are not FDA-approved, and major medical organizations caution that compounded dosing and purity can be inconsistent and that marketing claims often exceed the evidence. (support.endocrine.org)
Many experts do not support saliva testing as a reliable way to customize dosing for menopausal hormone therapy, because saliva levels may not reflect meaningful blood levels or symptoms in a consistent way. (mayoclinic.org)
Some people notice changes within a few weeks, while others need a longer adjustment period and follow-up fine-tuning. Symptom response, side effects, and your overall stress/sleep pattern all influence the timeline.
Cognitive symptoms can be multi-factorial (sleep, stress, metabolic health, nutrient status, thyroid, and more). Hormone support may help some people, but it’s usually most effective as part of a broader integrative plan.
Ask what options are FDA-approved vs. compounded, how risks are assessed, what follow-up looks like, what side effects to watch for, and what lifestyle steps will support long-term results.
