FAQs
TREATMENT & SAFETY
Is Oestra™ safe to use?
Yes. Oestra™ contains FDA-approved bioidentical hormones—estradiol and progesterone—delivered via a vaginal cream. This delivery method is supported by over 100 clinical studies for safety and efficacy.
Is Oestra™ bioidentical or synthetic?
Oestra™ uses 100% bioidentical hormones derived from plants. That means they’re chemically identical to what your body naturally produces—for better compatibility and fewer side effects.
What are the side effects?
Some women may experience mild breast tenderness or light spotting as their body adjusts. These are temporary and often resolve on their own or with small dosage adjustments.
How is your formulation different from what my doctor can prescribe?
Oestra™ is exclusive to Inner Balance and formulated by hormone specialists. Unlike standard prescriptions, our care team can make dose adjustments over time based on how you’re feeling.
Is it covered by insurance?
Our treatment isn’t typically covered. Insurance generally only supports treatments that bring you to “normal” lab levels—even if you still have symptoms. We focus on helping you reach optimal levels to truly feel better.
Do I need to stay on it forever?
You can stop at any time. But many women choose to continue long-term because they feel better. If you stop, symptoms typically return to how they were before treatment.
How do you know what dose to give me?
We start with a proven effective dose based on your symptoms. Then we tailor it over time. Unlike patches or pills, Oestra™ is flexible and made to adjust.
Is it safe?
Yes. Estradiol and progesterone have been FDA-approved for decades and are shown to be protective against many chronic conditions. There’s no evidence that estradiol increases breast cancer risk when used appropriately.
GETTING PRESCRIBED
Do I need a prescription for Oestra™?
Yes. After you take our quiz, a licensed provider will review your responses and prescribe Oestra™ if you’re eligible.
How do I get started?
Just take our 5-minute quiz. If you’re a candidate, we’ll ship your prescription directly to your door.
Can I use Oestra™ with birth control?
We don’t recommend combining Oestra™ with oral birth control. Non-hormonal options like copper IUDs are safe and effective alternatives.
Do I need a lab test to get started?
No lab test is required. We treat based on how you feel—not just lab numbers. You’ll receive ongoing monitoring and adjustments to ensure you feel your best.
