Estrogen and Progesterone Balance
Endometriosis is closely tied to estrogen, but balance is what matters. Tracking estradiol and progesterone shows whether your hormones are consistently out of sync, or just shifting with your cycle.

What our customers with
endometriosis are saying
I was doing everything right… but nothing was really changing.
I eat well, I exercise, I’ve tried all the supplements. I still had flare-ups and couldn’t figure out what was actually helping. Rythm gave me something real to look at. I could see my inflammation change, I could see how my body responded month to month. Some things I thought were working…weren’t doing much at all. That was a bit confronting, but also really helpful. Now I feel like I’m actually paying attention instead of just doing things and hoping.

I always thought it was random. It’s not.
I’ve had endometriosis for a while and every cycle felt like a surprise. Some months were fine, some were horrible, and I couldn’t figure out why. I’d try things and just hope for the best. With Rythm, I started noticing my estrogen was higher on the months I felt worse, and my progesterone wasn’t really catching up. Then I saw my inflammation was up during those same times. Rythm has been really insightful and helped me change my lifestyle to support what’s actually going on at that time.

Gave me clarity before trying for a baby.
I have endometriosis, so before trying for a baby I did a few months with Rythm. I could see what my hormones were actually doing across my cycle.I brought the results to my doctor and it made the whole conversation a lot more clear. We weren’t starting from scratch.Rythm has been such a good tool, really easy to use, and it gave me a lot more peace of mind and clarity. I’d recommend it to anyone.

Frequently Asked Questions
How is Rythm different?
Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.
Does Rythm help me improve?
Rythm provides actionable suggestions and tips to help you optimize each biomarker
Is Rythm HIPAA compliant?
Yes, Rythm is HIPAA compliant. Your data is securely stored and handled in accordance with strict privacy and security standards.
Can I cancel anytime without fees?

Does Rythm accept HSA/FSA payments?
Yes, Rythm is HSA/FSA eligible. You can use your HSA or FSA card at checkout or submit your Rythm receipt to your provider for reimbursement.

Frequently Asked Questions
How is Rythm different?
Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.
