byMae isn't just a name—it’s a commitment. It comes from "mae," a word that carries the strength and nurturing spirit of motherhood, but also the energy of new beginnings and growth. It’s not about playing into trends, but about paying homage to the essence of who we are: driven by the belief that the right care at the right time can change everything.
When three professionals with diverse expertise met in a maternal mental health program, they weren’t looking to start a company—they were looking for answers.
Ready for anything health
byMae is more than just a health company—we’re here to elevate well-being for every generation.
We’re not here to do what’s easy—we’re here to do what matters. Our mission is simple: to redefine health by treating every person with the care they deserve, focusing on the overlooked steps that truly make a difference.
Investing where it counts
We’re diving into the areas of health research that have been historically overlooked but are critically needed. Think maternal mental health, the untold journey of perimenopause and menopause, and the power of immunity and gut support. We’re just getting started, but we’re determined to shift the narrative where it matters most.
Formulating the
future of health
Our products aren’t just about filling gaps—they’re about filling lives with the support they need at life’s most crucial stages. And here’s the twist: every product you purchase helps fund the very research that drives us forward.
Making impact personal
We’re not stopping at products. We’re working directly with communities to discover practical solutions that uplift health and wellbeing for everyone involved. From shaping policies to driving social impact, we’re committed to creating a healthier future, together.
What's in a name? Everything.
They saw the gaps in the system, the moments when families are most vulnerable, and they knew something had to change. byMae was born from the conviction that science, innovation, and compassion aren’t just complementary—they’re essential.
So why byMae? Because we believe that building a healthier future isn’t just about creating products—it’s about ensuring that every solution is rooted in the very best of what science and humanity have to offer. It’s byMae, and it’s by design.
