What Hormones Are Used in BHRT? The Answers to Your Top Questions

BHRT is definately having a moment. Keep reading to learn more around what is typically prescribed when you start an Hormone Replacement Therapy Regimen.

Bioidentical Hormone Replacement Therapy (BHRT) focuses on restoring balance by replacing up to four primary hormones: estrogen, progesterone, testosterone, and DHEA.

Rather than a one-size-fits-all approach, your BHRT specialist will look at your age, symptoms, and lab work to prescribe the exact combinations needed to bring your levels back to their optimal baseline during perimenopause and menopause.

Providers like Joi Women's Wellness partner with Labcorp so you can get labs done at a location convenient to your home or office. The results are shared with you and Joi. Then used to plan for your 30-minute 1:1 consultation with a Joi Clinician.

Is Bioidentical Just a Marketing Buzzword or a Real Difference?

With so much noise in the wellness space, it is easy to wonder if "bioidentical" is just a clever marketing term designed to sell custom creams and premium supplements. The short answer? No, it isn't a gimmick—there is a profound, microscopic difference between bioidentical hormones and traditional synthetic options. The distinction lies entirely in their molecular structure and how seamlessly they fit into your body’s cellular receptors.

The old fashioned, traditional hormone replacement therapy (HRT) often utilizes synthetic hormones or non-human estrogens (such as conjugated equine estrogens derived from pregnant mares' urine). While these compounds are strong enough to bind to human receptors and relieve symptoms like hot flashes, they are not exact replicas of what your body naturally produces. Because the molecular structure is slightly altered or foreign, the body processes it differently, which is often what leads to the unwanted side effects and health risks traditionally associated with older forms of HRT.

Bioidentical hormones, on the other hand, are an exact molecular match—atom for atom—to the hormones your ovaries naturally created for decades. Usually derived from plant sources like wild yams or soy and synthesized in a lab, chemicals like estradiol and progesterone are shaped precisely like your own cellular "keys."

What Hormones are Used in Hormone Replacement Therapy (HRT)

When navigating hormone replacement therapy, it helps to look at your body as a finely tuned ecosystem. During perimenopause and menopause, the production of several key chemical messengers begins to fluctuate and decline. HRT is designed to step in and supplement these specific deficiencies.

1. Estrogen: The Multi-Tasker

Estrogen impacts far more than reproduction. In BHRT, specialists typically prescribe estradiol—the most potent form of estrogen your ovaries naturally produced. Replacing it directly targets the most disruptive menopausal symptoms, like hot flashes, night sweats, and brain fog, while providing long-term protection for your bones and heart.

2. Progesterone: The Great Calmer

If you have a uterus, progesterone is required alongside estrogen to protect the uterine lining from overgrowth. Beyond that safety role, bioidentical micronized progesterone acts as a natural calming agent for the nervous system. Taking it before bed drastically improves sleep quality, reduces nighttime anxiety, and helps stabilize mood swings.

3. Testosterone: The Energy and Vitality Driver

Though often labeled a male hormone, testosterone is crucial for female vitality. When levels drop during midlife, women frequently face loss of muscle tone, persistent fatigue, brain fog, and a low libido. Introducing small, female-optimized doses of bioidentical testosterone can restore physical strength, metabolism, mental clarity, and sexual desire.

4. DHEA: The Baseline Building Block

DHEA is a precursor hormone produced by your adrenal glands, acting as the raw material your body converts into estrogen and testosterone. While not every woman needs it, supplementing a DHEA deficiency can improve cellular energy, support immune health, and provide a welcome cognitive and metabolic boost during hormonal transitions.

Which Specific Hormones Does a Woman Actually Need to Replace?

There is no single, standard formula for hormone replacement because every woman’s biochemical fingerprint and menopausal transition are unique. Deciding exactly which hormones you need to replace—and how much of them your body requires—comes down to two primary clinical philosophies in modern medicine.

Today’s online telemedicine platforms make it incredibly easy to access care, but they tend to approach personalization from these two distinctly different angles.

The Diagnostics-First Approach (Data & Labs)

Some virtual care providers, like Joi Women’s Wellness, rely heavily on comprehensive data right out of the gate. Before a doctor will write a single prescription, you are required to complete an extensive lab panel (often testing 50+ distinct biomarkers).

This baseline blood work gives clinicians an exact, measurable look at your hormone levels, metabolic function, and thyroid performance. For women who want to see the numbers in black and white, this approach completely eliminates the guesswork and creates a highly precise, data-driven starting line.  

The Evidence-Based, Symptom-Led Approach

On the other side of the spectrum, specialized providers like Inner Balance operate on an evidence-based medicine model that prioritizes your physical reality over a lab slip. Because hormone levels can fluctuate wildly throughout the day during perimenopause—rendering blood tests up to 30% inaccurate at times—these specialists focus deeply on your age, health history, and specific clinical symptoms.

If you are experiencing heavy bleeding, chronic insomnia, and intense brain fog, those symptoms tell a definitive story of a hormone deficiency. A customized prescription is then built to treat the clinical presentation directly, rather than chasing fluctuating numbers on a page.  

The Ultimate Measuring Stick: How You Feel

Regardless of whether your provider starts with a blood draw or a detailed symptom assessment, the initialization of BHRT is just the baseline. From that point forward, your own body becomes the ultimate guide.

As time goes on, how you actually feel day-to-day serves as the true metric of success. Hormone optimization is an iterative process. You might find that your sleep improves within the first two weeks, but your mental clarity or libido takes a few months to fully return.

Home Hormone Test Vs. Labs

At-home kits like Mira or Proov are great for validating perimenopause, but blood labs offer definitive data.

The catch? Blood numbers only reflect a single micro-moment. Hormones fluctuate aggressively—a 9:00 AM level can vanish by 10:30 AM. Chasing these volatile numbers is why evidence-based providers skip upfront labs and start with a gold-standard foundational dose instead.

The real magic happens at the 90-day mark once your body adapts. Reputable providers use this milestone for a telehealth check-in to tweak your dose based on real-world data: your actual symptoms.

This symptom-led approach works. Since using Oestra by Inner Balance, I’m experiencing the best sleep of my life. Is it perfect every night? No, but the consistency and quality of my rest are night and day compared to where I started.

HRT Fast Track: How to Skip Doctor Waiting Lists and Get Relief Now

Traditional gynecologists often have three- to six-month waiting lists. When you are dealing with debilitating insomnia and hot flashes, waiting half a year for a 15-minute appointment is unacceptable. Fortunately, modern telemedicine eliminates the wait.

Finding clarity wasn't easy. I vetted seven providers and multiple formulations to find what works (see my Trusted Providers Page for the full breakdown). For a long time, my gold standard was the data-heavy approach with Joi Women's Wellness. Their extensive labs were fascinating, and I stabilized on their top protocol: an estrogen patch, oral progesterone, and vaginal cream.

Yet, even though my lab numbers looked great on paper, I still wasn't sleeping as well as I wanted. I knew my body was capable of more, so I kept searching. That led me to Inner Balance. Since July 2025, I’ve been using their all-in-one formulation, Oestra. For me, it is by far the best HRT I've ever tried—delivering the deep, consistent rest that patches and pills couldn't.
