Estrogen is one of the most effective longevity interventions for women.
FDA announcement, November 2025
Endometriosis is more than pain—it’s inflammation driven by hormones
Endometriosis isn’t just a reproductive issue. It’s chronic
inflammation—and hormones play a major role.
When progesterone is low or not working properly, the body can’t regulate the endometrial tissue the way it should.
Most treatments don’t fix this.
They suppress it.
Oestra is different.
Estrogen is one of the most effective longevity interventions for women.
FDA announcement, November 2025
Once a day application.
Hormone balance, simplified.
A different approach to endometriosis symptoms
Instead of shutting down your hormones or removing tissue, what if you supported your body at the root?

Real guidance from the
doctor behind Oestra®
Dr. Sarah created Inner Balance to deliver a different kind of hormonal care.
Her approach centers on bioidentical hormone enrichment, safe delivery methods, and treatment guided by how women actually feel - not just lab numbers.
Traditional hormone therapy often targets a few symptoms like hot flashes or sleep. Oestra takes a broader approach, supporting brain function, metabolism, energy, skin, and overall wellbeing.
Vaginal delivery allows hormones to be absorbed directly into the bloodstream, supporting more stable levels and consistent symptom relief. Oral and topical methods are less efficient.
Estradiol and progesterone work together to support brain function, metabolism, skin, sleep, and overall balance. Using both creates a more complete and effective approach.
Oestra combines estradiol and progesterone into one daily treatment, replacing multiple prescriptions. This makes therapy easier to follow and more effective long term.
Most hormone therapy involves multiple prescriptions, labs, and long trial-and-error timelines. Oestra simplifies this into a streamlined, easier-to-follow approach.
Oestra uses bioidentical hormones identical to what the body produces. Treatment is monitored and adjusted, supporting safe, long-term use.
Many women notice early improvements in sleep and mood within weeks, with deeper changes like skin and cognitive function improving over 2–3 months.
Treatment begins with clinician review, followed by prescription delivery and ongoing adjustments based on how you feel, with continued clinical support.
Oestra supports natural hormone balance by allowing the body to convert progesterone into testosterone as needed, avoiding unnecessary side effects.
Oestra is a clinician-guided prescription therapy compounded in a licensed pharmacy and tailored to your symptoms.
Symptoms often reveal hormone imbalance more accurately than lab tests, which can appear normal despite real changes in how you feel.
Oestra was created after seeing consistent patterns of dismissed symptoms and overly complex care, with the goal of simplifying treatment and improving how women feel.
Hormonal changes begin earlier than most women expect. Starting support during perimenopause can help stabilize symptoms before they worsen.

Questions?
TREATMENTS & SAFETY
Yes. Oestra® contains estradiol and progesterone—bioidentical hormones that are FDA-approved for use in treating hormone deficiency. It’s also delivered vaginally, a method backed by over 100 high-quality studies showing stable hormone levels, systemic benefits, and protection of the uterine lining. Safety isn’t just a promise—it’s clinically supported.
Yes. Hormone therapy is one of the most extensively studied treatments in medicine, with decades of research supporting its safety when used under medical supervision. Oestra® uses bioidentical estradiol and micronized progesterone — hormones identical to those naturally produced by your body — to support healthy hormone balance. If you ever choose to stop treatment, you can do so at any time. Your hormone levels will simply return to their natural baseline. Our medical team monitors your treatment and guides adjustments to ensure it remains safe and effective for you.
It goes beyond that. Oestra® is made by a 503B FDA-regulated compounding pharmacy that’s inspected by the FDA, DEA, and state licensing boards. Every prescription batch undergoes rigorous potency, purity, and safety checks before it ever reaches your door.
Yes, when they’re held to the highest regulatory standards—as ours is. Our partner pharmacy is LegitScript-certified, meaning it meets stringent quality and safety criteria. You’re getting the best of personalized medicine with pharmaceutical-grade oversight.
Oestra® uses only bioidentical hormones—compounds identical to the ones your body used to make, derived from plant sources. In plain terms: they’re natural to your body, better tolerated than synthetics, and designed to restore—not override—your natural balance.
Two major ways:
– Delivery: Oestra® is a vaginal cream, allowing for faster absorption and more stable hormone levels than oral pills or topical patches.
– Formulation: It’s an all-in-one treatment. One pump a day delivers estradiol, progesterone, and testosterone (via conversion), saving you from juggling 4–6 separate prescriptions.
Yes. Herbal supplements may temporarily ease symptoms, but they can’t restore hormone levels. Your body doesn’t make Dong Quai or Chaste Berry—it makes hormones. Oestra® gives your body what it actually needs, in the correct ratios, with prescription-level quality and precision.
No. Lab work is not required to begin treatment. Your care is guided first and foremost by your symptoms, medical history, and a comprehensive clinical review — not just lab numbers. Many hormone imbalances can be identified clinically, and you can begin treatment without testing. If you’d like deeper insight, we do offer convenient lab testing, and a full clinical review of your results is included in your care. Labs are optional — your journey with us will be personalized either way. You can start feeling better now, and add testing later if and when it makes sense for you.
No. In fact, Oestra® is designed to help correct estrogen dominance — not cause it. Estrogen dominance often occurs when progesterone levels are too low relative to estrogen. Oestra® provides both progesterone and estradiol in a carefully balanced ratio to help restore hormonal balance and calm the fluctuations that can drive symptoms. Because the hormones in Oestra® are delivered vaginally, they are absorbed efficiently and avoid the liver metabolism that can sometimes contribute to hormonal imbalances. This allows for more stable hormone levels and a more balanced response. Our medical team also personalizes dosing and monitors your progress to ensure your treatment remains balanced and effective for your body.
Most women tolerate Oestra® very well. As your body adjusts to hormone optimization, some women may experience mild breast tenderness or light cramping during the first few weeks. These symptoms are typically temporary and resolve quickly. Less common side effects may occur but are usually mild and easily addressed with simple adjustments to dosing or supportive recommendations. Our medical care team monitors your progress and is here to guide you every step of the way, ensuring your treatment remains comfortable, effective, and personalized to your needs.
No — Oestra® is non-contraceptive and does not suppress ovulation.
Yes. Bioidentical hormones are safe to take for decades and actually support longevity and disease prevention.
GETTING PRESCRIBED
Start by taking our health quiz. If you’re a candidate, you’ll move straight to checkout. After a licensed clinician reviews your info, your prescription is sent to the pharmacy and shipped directly to you. You’ll receive a 3-month supply as part of a monthly subscription.
Yes. Every Oestra®prescription is reviewed and approved by a licensed clinician. You don’t need to book a separate appointment - your quiz responses help us determine if it’s safe to begin treatment and ensure you're a good candidate for our starting dose.
We don’t isolate hormones - we balance them. Most HRT programs target estrogen, progesterone, or testosterone in isolation. Oestra® is different. It supports all three hormones together in the right ratios, to restore balance without the usual trial-and-error or side effects.
PRODUCT USE
Apply one pearl-sized pump of cream daily to vaginal tissue using your finger. An applicator will be available in the future, but for now, we recommend manual application for best results.
You may start noticing changes within the first 2–4 weeks—especially around mood, sleep, and vaginal dryness. Deeper shifts like energy, skin, and metabolism take longer, often 3–6 months or more. Oestra® isn’t a quick fix; it’s a full-body recalibration. But when balance returns, it’s worth the wait.
Oestra® is delivered every 3 months, and billed monthly. Your membership includes treatment, pharmacy processing, shipping, and unlimited clinical support.
ELIGIBILITY & ACCESS
Not at all. We work with women as young as 21. In fact, many women start in their 30s or 40s—often before traditional medicine recognizes hormone decline. The earlier you begin, the more protection you provide your bones, brain, heart, skin, and metabolism.
It’s not—because insurance typically only covers the most limited options. Oestra® replaces 5–6 prescriptions and is still more cost-effective than most HRT plans. HSA/FSA is also accepted at checkout.
Yes, we accept HSA/FSA directly at checkout. Most carriers accept prescriptions as eligible and we also provide a letter of medical necessity.
SHIPPING & DELIVERY
Yes. Shipping is always free—every Oestra® prescription ships at no extra cost.
Most orders ship within 3 business days after your prescription is approved. We like to give your pharmacy time to prepare everything safely.
Yes. Your order arrives in plain pharmacy-labeled packaging, with no mention of hormones or Inner Balance on the outside. Inside, you’ll find your medication and a pharmacy insert with usage guidance.
