The Flow is the only non-profit in California focusing exclusively on reusable menstrual products. Providing culturally-specific and multilingual education about menstrual cups and donating them, The Flow works to serve under-resourced communities. Our work is at the intersection of social justice, health, and environment advocacy.



At The Flow, we're dedicated to achieving Period Equity for All. In the United States, 1 in 4 teens faces challenges affording period products, leading to missed school days. Globally, low-income families make agonizing choices between menstrual products and essentials like food. The stigma surrounding periods perpetuates gender inequalities and poses health risks. We're committed to breaking these barriers through advocacy and education, ensuring access to affordable, sustainable menstrual products.


  • Economic Empowerment: Cups cost less than a few months of disposable products. Over a lifetime, a woman can save over $4000 by choosing a menstrual cup.

  • Sustainable and Green: Cups can be safely reused for up to 10 years, reducing waste in septic systems, landfills, and oceans. They require less energy for production and shipping, contributing to a greener planet.

  • Health and Wellness: Cups can be worn for up to 12 hours, collecting three times more blood than tampons or pads. Free from harmful chemicals, they pose less risk of toxic shock syndrome and eliminate issues like drying or tearing

  • Empowerment Through Education: Menstrual cups empower individuals by fostering a deeper understanding of their bodies, leading to better health outcomes. Education about cups also helps break stigmas and shame associated with menstruation

  • Inclusivity: Menstrual cups provide an alternative option for gender-expansive communities, contributing to a more equitable approach to menstrual care.



So far, we've donated over 12,000 cups to over 65 partner organizations and individuals all around the world!

Our Mission: Period Equity for All

Why Menstrual Cups?

Our Partners



The Flow World is all about making sure menstruators have the knowledge they need to access and advocate for menstrual equity.


Here, at The Flow, we’re motivated to get the word out about resuables because…they’re great and more people should try them. Kind to your body. Light on your wallet. And easy on the environment. For example, one menstrual cup can stay in up to 12 hours, last up to 10 years and cost only $20-$40. It may not be rocket science but it is mind-blowing!


We’re especially interested in getting information to moms and to soon-to-be/new menstruators because we want to do better for our teen daughters and other girls. We hope that they can experience menstruation in a climate of period positivity and with more choices. And help spread that confidence and power to girls everywhere. We also distribute information and reusables to the people who need them most – low-income menstruators here in the US and everywhere!


Finally, we want to support and motivate others to support equity legislation around menstruation – like providing free menstrual products to people who can’t afford them. It’s about fairness, social justice and health. Hopefully, unlike so many other issues, it’s something we can all get behind.

So please help us get closer to the day when all girls can start their menstrual journey with laughter and choices, and we all live better, fairer and healthier!

Thank you!
