A new era of menstrual care
Developed in Denmark - created by menstruators for menstruators.
Look forward to your next best cycle.
Founder story
How did Flow come about?
I started Flow Intimates three months after the birth of my daughter in 2021. That was the time my body needed to adjust from being pregnant to menstruating again.
But I was nowhere near ready, with my body leaking everywhere, or for old period products after a year and a half of fertility treatment. I searched for:
〰️ A non-invasive menstrual product to manage my period.
〰️ A reusable solution that kept me on the course I had set years earlier by saying goodbye to pads and tampons
〰️ A solution that was delicious for me. I was tired of the habit of pulling out the most worn-out panties from the drawer for my bleeding days - it didn't exactly make me feel better when I was bleeding.
〰️ Products for my cycle that I could feel safe with. No perfume, no chemicals, just softness for my lower abdomen and milky breasts.
What we are most proud of
5 good reasons why you'll love us
THE HEART ALWAYS COMES FIRST
We are also here to make bigger changes than just in your daily life.
Our founder changed Danish legislation in 2021 by having the age limit on frozen eggs removed.
In 2025, we created the Red Flag campaign, which ensured the Danish women's national handball team the right to wear dark shorts during the World Cup. And we will continue.
SAFETY AND SECURITY IMMEDIATELY AFTERWARDS
Despite a lack of legislation and safety requirements for menstrual products in the EU, we do not hesitate to take responsibility. We do not use PFAS, nanosilver – no magical "stay fresh" treatments on the absorbent layers. We third-party test our underwear for chemicals and use innovation without compromising your safety to solve odor issues.
PREMIUM PRODUCTION
We produce in Portugal, Denmark, Lithuania, and Turkey – and always with the best materials such as organic cotton, organic merino wool, and ECONYL®.
Our partners are the best in their respective fields, and several of our factories are GOTS-certified, which places demands on employee welfare.
BY MENSTRUATORS FOR MENSTRUATORS
We create products we need ourselves - and test them thoroughly (so yes, they are tested with real menstrual blood). In addition, we have a test panel consisting of hardcore and dedicated members from our community who take the task seriously.
MORE THAN MENSTRUATION
We know. It's about much more than menstruation. It's about a changing body - throughout the entire cycle, month after month.
That's why we are redefining what 'period products' are beyond a practical solution. The best-rated absorbent underwear, of course, but also care that supports you and your body throughout the entire cycle.
That is Flow Cycle Routine.



Always premium quality - never PFAS or nanosilver

Flow principles
Our first priority at the time was to find a supplier with a code of ethics we could support.
Our supplier in Turkey is GOTS certified, as is our Portuguese supplier.
The fact that our suppliers are certified to GOTS guarantees us independent certification of the entire supply chain.
When a supplier is certified, it means that there is a regulated minimum wage, no discrimination, a safe and hygienic working environment, decent and regulated working hours, the right to bargain collectively, and so on.
That we are discovering in the 2020s that our period products are filled with lead, perfumes, bleaches, PFAS, nanosilver and other unwanted chemicals and heavy metals is beyond us.
We do not use any chemical 'stay fresh' treatments in our underwear, and you can read more about the safety of our products here.
We only make products that we love and use ourselves. They must last through everyday use.
The world is full of poor quality, and the spiral is downward.
We insist on proper quality, and you can see this in the materials we use, such as organic cotton, organic merino wool, lyocell, Econyl.
🩸We will show you the reality you already know.
🩸We test our panties with real menstrual blood.
🩸If we show blood, we show you real menstrual blood from real menstruating women.
🩸We believe that you can do a lot, even when you're menstruating - but you don't have to.
🩸We want to create an embracing, knowledgeable and inclusive place where we tell things as they are.
🩸We will try to influence our surroundings to greater understanding and insight through a positive focus on what we want even more.

Flow is constantly doing small collaborations with other creative brands. Some collaborations will be more permanent, while others will be "here and now", so if you want to support them, you'll have to hurry.
It can be difficult to always be the smallest in an industry where it is often about volume and speed.
We have a small panel of skilled testers who help develop our products with us.
We are very grateful for the trust and time they give us. If you also want to test, please sign up.
Flow is not just an underwear brand. We are also a universe of knowledge about:
- Menstrual cycle
- Fertility
- Postpartum
- Perimenopause and transition
- Mental health and cycle
We believe that knowledge creates security - both of which we lacked in our childhood and youth.
That's why you'll find guides, articles and professionally verified content, always written at eye level - in our Flow Journal,
From the start, we have prioritized top of line suppliers - close to home. This means that we can drive our goods home instead of flying or sailing. This saves CO2 on transport.

Om Flow Intimates - dansk fem-tech brand
Flow Intimates er et dansk femtech-brand, der udvikler produkter til kvinder gennem hele livet – fra den første menstruation til overgangsalderen.
Vi tror på, at kvinders sundhed fortjener den samme innovation, kvalitet og opmærksomhed som alle andre områder af sundhed. Derfor udvikler vi produkter, der kombinerer funktion, komfort og gennemtænkt design, samtidig med at vi arbejder for mere viden, større gennemsigtighed og færre tabuer.
Vores mission kan opsummeres med seks ord:
Fra menarche til menopause.
Hvorfor blev Flow skabt?
Flow begyndte med en frustration.
Hvorfor var der så få gode alternativer til bind og tamponer? Hvorfor blev kvinders sundhed stadig behandlet som en niche, når halvdelen af verdens befolkning menstruerer? Og hvorfor var det så svært at finde produkter, man kunne have fuld tillid til?
I 2021 lancerede vi Flow som en af de første danske virksomheder med fokus på menstruationstrusser. Siden da er vi vokset til et univers, der favner langt mere end menstruation.
I dag udvikler vi produkter til menstruation, postpartum, let urinlækage og hverdagsbeskyttelse – altid med udgangspunkt i kvinders virkelige behov.
Vi tror på bedre produkter
Et godt produkt skal ikke bare fungere. Det skal føles rigtigt.
Derfor arbejder vi med materialer, pasformer og detaljer, som gør en forskel i hverdagen. Vores produkter udvikles med fokus på komfort, holdbarhed og gennemtænkte løsninger, så de bliver en naturlig del af livet – ikke noget, du skal kæmpe med.
Vi udvikler blandt andet:
-
Menstruationstrusser
-
Menstruationsbadetøj
-
Absorberende undertøj til hverdagsbrug
-
Postpartum-produkter
-
Flow Care – plejeprodukter udviklet til kvinders krop gennem hele cyklussen
Vi tror på gennemsigtighed
Kvinder har ret til at vide, hvad de produkter, de bruger tæt på kroppen, indeholder.
Derfor arbejder vi for større transparens omkring materialer, produktion og produktudvikling. Vi udvikler vores absorberende produkter uden PFAS og uden tilsatte biocider som nanosølv og deler løbende den forskning og viden, der kan hjælpe kvinder med at træffe informerede valg.
For os er gennemsigtighed ikke en trend. Det er en grundlæggende værdi.
Vi tror på mere viden og færre tabuer
Produkter kan gøre en forskel. Men det kan viden også.
Derfor er Flow mere end en webshop.
Gennem Flow Journal deler vi artikler om menstruation, fertilitet, pubertet, postpartum og kvinders sundhed. Vi udgiver bøger, udvikler undervisningsmateriale og engagerer os i projekter, der arbejder for større åbenhed og bedre regulering af menstruationsprodukter.
Vi tror på, at bedre information giver bedre valg.
Dansk design – produceret i Europa
Vi samarbejder med specialiserede europæiske producenter, som deler vores fokus på kvalitet og ansvarlig produktion.
Ved at udvikle vores produkter tæt på hjemmemarkedet kan vi følge processen, stille høje krav til materialer og løbende forbedre vores kollektioner.
Vi tror på, at kvalitet handler om de valg, der bliver truffet længe før produktet ligger i skuffen derhjemme.
Mød menneskene bag Flow
Flow blev grundlagt af Cathrine Widunok Wichmand, journalist, forfatter og iværksætter.
I dag er Flow vokset til et team, der arbejder hver dag for at udvikle produkter og dele viden, som gør en forskel for kvinder gennem hele livet.
Vi er stolte af at have været blandt de første til at introducere menstruationstrusser i Danmark, at samarbejde med blandt andre Matas og at være en del af den voksende bevægelse, der arbejder for mere fokus på kvinders sundhed.
Vi er kun lige begyndt
Kvinders sundhed er stadig et område med enorme muligheder for innovation.
Flow udvikler derfor løbende nye produkter, deler ny viden og arbejder for større gennemsigtighed i branchen. Samtidig engagerer vi os i initiativer som The Period Project, der arbejder for bedre regulering og større transparens omkring menstruationsprodukter i Europa.
Vi tror på, at små forbedringer i hverdagen kan skabe store forandringer over tid.
Og vi glæder os til at fortsætte rejsen sammen med dig.
