We built what we couldn't find.
Phase started because three women — a clinical nutritionist, a women's health pharmacist, and a sleep researcher — all hit menopause and came up empty. No honest information. No products that worked. No one who talked to them like adults.
Menopause isn't a disorder.
It's a phase. Treat it like one.
The average woman spends 7 years in perimenopause or menopause before getting meaningful support. Most are told to "try lifestyle changes" or handed an HRT prescription with no context.
We believe women deserve honest information, clinically tested solutions, and a brand that doesn't treat their biology as a problem to be solved in a pamphlet. Phase curates the most rigorously tested menopause wellness products — from Bonafide, Kindra, Hilma, and others — so you don't have to spend 200 hours on PubMed to figure out what actually works.
Built by women who lived it.
Three clinicians. Three menopause journeys. One company.
22 years in clinical nutrition. Hit menopause at 51 and spent two years figuring out what was happening without adequate support. Built Phase so no woman has to do that alone.
Board-certified women's health pharmacist with 18 years of clinical practice. Vets every product in the Phase catalog for ingredient quality, bioavailability, and drug interactions.
Sleep researcher at a major academic medical center for 15 years. Her own insomnia during perimenopause sparked the sleep category. Everything in the Sleep collection is something she'd prescribe.
How we choose what's in the catalog.
We only carry products we'd take ourselves, or recommend to our patients.
Clinically Studied
Every product must have peer-reviewed clinical data supporting its primary claim — not just "studies show ingredients may help."
Hormone-Free
All Phase products are hormone-free and safe for women who can't or don't want to use HRT — including those with hormone-sensitive conditions.
Third-Party Tested
Independent lab verification for purity, potency, and contaminants. We check the certificates of analysis — not just the label.
Real-World Tested
Before a product enters the catalog, at least one Phase founder or advisor has used it. Preferably for 90 days. No exceptions.
How Phase became what it is.
In 2021, Margaret Chen walked into her gynecologist's office convinced she was having a cardiac event. Racing heart. Drenching sweats at 2am. A fog so thick she'd forgotten her own phone number in a client meeting. She was 51.
Her doctor said: "This is menopause. You can try HRT or lifestyle changes." No nuance. No explanation of what was actually happening to her hormones. No guidance on what "lifestyle changes" actually meant beyond "exercise more and stress less."
"I was a clinical nutritionist. I knew how to read research. And I still spent two years figuring this out on my own. That should not happen to anyone."
She called Sandra Park, a pharmacist friend who'd recently had the same experience. And then Keiko Yamamoto, a sleep researcher colleague who'd been studying hormonal insomnia for years but had never connected it to her own midnight wake-ups.
Together, they spent six months reviewing clinical literature, testing products on themselves, and building the framework for what Phase would become: not a supplement company, but a curated catalog of the most rigorously tested menopause wellness products available — with honest, no-fluff explanations of what each one actually does and why.
Today, Phase supports over 12,000 women across 23 countries. Every product in the catalog is something at least one founder takes, has taken, or would recommend to a patient. That's the only standard that matters.
