You are Known. here.
No girl should meet her first period alone in a school bathroom.
Personal, not normal.
Girls are told that periods, and the pain that comes with them, are "normal." But normal is hard to make sense of when something hurts, and it quietly teaches her to tune out her own body. Vitally Known. starts with personal: what's happening to her body has a name, has a community, and has always been hers.
We're building it with each girl at the center: helping her caregivers and pediatricians have better conversations about what to expect, giving her the words and the data to advocate for her own health, and shaping our products around her life, so she never feels unprepared for the life she wants to lead.
For parents and caregivers 18+. Takes about 2 minutes.
"It was very awkward. We didn't talk about it. There wasn't a lot of support. And I just wanted something completely different for her."
"There are kind of signs, but there's also not signs. Like, you can get it on any given day. It's really confusing."

ACOG, February 2026 · JCEM, 1,056 U.S. women with PCOS, 2025Raising a generation of girls who speak up for their health.
Twenty years ago, pediatricians and gynecologists named the menstrual cycle a vital sign, as telling as pulse or blood pressure. Yet too many girls are still never taught to read it, and conditions like endometriosis and PCOS can go years without a diagnosis.
That is starting to change. Women are speaking up about their health like never before, and medicine is listening: in February 2026, ACOG issued new guidance to shorten the time to an endometriosis diagnosis.
Vitally Known. starts that advocacy at the very beginning. When a girl learns at 8, 10 or 12 that her cycle is a vital sign, she grows up knowing her body, trusting what she feels and having the words and the data to be heard. We're building so future generations of women are raised with health advocacy from the start, not left to find it on their own.
Ready before it starts. Supported once it does.
Vitally Known. is designed for girls 8-17 and the grown-ups who love them. Starting before her first period and staying with her as she navigates her health journey. Here's what's in development.
Learn it together
Age-right lessons, a gentle cycle tracker, and a caregiver view so you can learn side by side. Private by design and built for kids' privacy rules from day one.
Ready in her backpack
A small, discreet bag that tucks into her backpack with everything she needs for day one, plus simple guidance that speaks to her, so the first time feels prepared instead of scary. Comes with conversation guides for caregivers, in multiple languages.
Made for the life she leads
Personalized deliveries of the products she needs to keep doing what she loves, timed to arrive each month before she needs them. We're brand neutral, so every Edit is curated around her body and her life. A swimmer can add period swimwear. A dancer can add period underwear made for the studio. As her seasons, sports and schedule change, her Edit changes with her.
A heads-up, not a surprise
Periods are often irregular for the first couple of years. Signal is a bracelet designed to give her a 48-hour heads-up, so she can say yes to practice, school and sleepovers without worrying about a surprise.
Walk in ready to talk
Simple health cards that turn what she tracks in the app and what Signal notices into clear points and questions, so she and her caregiver can have a better conversation with her doctor. Every visit builds her confidence in her body and her voice to speak up for her own health.
A circle of care around every girl
Vitally Known. is more than an app or a kit. We're building a health advocacy platform with girls, caregivers and doctors, so she has information she feels safe with, grown-ups who understand, and her own health story to speak up with.
Information she feels safe with
Honest, age-right answers in a private space that's hers. She learns that her body is hers to understand and that her questions always deserve real answers.
Caregivers in the loop
A caregiver view and conversation guides help parents support her without taking over, so one big talk becomes lots of small, easy ones.
Data that speaks for her
Signal builds a health story over time: cycle timing, symptoms and pain in her own words. Doctor-Ready Talking Cards help her bring it to her doctor and close the gap that leaves conditions like endometriosis undiagnosed for 4 to 11 years. We're in conversation with pediatric partners to shape what doctors see.

Before you join
Why Vitally Known., and why now?
Twenty years ago, pediatricians and gynecologists named the menstrual cycle a vital sign. Yet too many girls are still never taught to read it, and conditions like endometriosis and PCOS can go years without a diagnosis. Women are now speaking up about their health like never before, and medicine is listening. Vitally Known. starts that advocacy at the very beginning, so future generations of women are raised knowing their bodies and speaking up for their health from the start.
Can my daughter sign up?
Not here. This list is for adults 18 and older only. We don't collect any information from children. When Vitally Known. launches for girls, it will be built around kids' privacy laws from the start, with a caregiver in the loop.
What happens to my information?
We use it to keep you updated on Vitally Known. and to learn what families need most. Survey answers are reviewed in aggregate. We never sell your information, and you can ask us to delete it anytime.
Is Vitally Known. available now?
Not yet. We're in the building stage, and Founding Families are helping us decide what comes first. You'll hear from us before anyone else when it's ready.
Who is behind Vitally Known.?
Vitally Known. was founded by Cristina Charles, who has spent 20 years building consumer brands. Alongside that work, she has long supported women and girls through NGO and philanthropic projects, and Vitally Known. brings those two sides of her life together. Behavioral scientist Dr. Steph Habif is one of our founding board members, because changing how families talk about periods, and how girls speak up for their health, is at the heart of our mission.
