A supplement company built around a question no one was answering.
Peri-menopause affects nearly every woman, often for a full decade — yet receives less than 1% of women's health research funding. Vesper exists to close that gap, with daily formulas designed specifically for the hormonal shifts of the years before menopause. Clinically informed. Quietly effective. Made to be taken consistently — not occasionally.
It started the year I stopped recognizing my own body.

I didn't see it coming.
I was 44, running a team of 60 in Brooklyn, and I'd always been the one who could handle it. Then one Tuesday in March, I sat down at my desk and I couldn't. I couldn't read the email in front of me. I couldn't remember a name I'd known for ten years. My hands were shaking. I went home at noon. I didn't come back for eight months.
The diagnosis was burnout. But underneath the burnout was something no one had mentioned to me — not my mother, not my OB-GYN, not a single one of the wellness books on my shelf. I had walked into peri-menopause blind. I thought I was losing my mind. I was actually losing my estradiol.
I built Vesper because no woman should hit that wall the way I did. Because our mothers didn't talk about it. Because the research doesn't fund it. Because the shelves don't stock for it. And because once you know what's happening in your body, you can actually do something about it.
This company is what I needed at 44. I hope it's what you need now — and that you find it before you hit the wall, not after.
