Our Story
When our kids get sick, so does the whole family
As three professionals who met in a maternal health program, one of the many things we bonded over was the chaos that comes along with kids getting sick. When our kids get sick, the entire household goes down – and no one can afford that. Determined to find ways to boost our overall health, we discovered a game-changing insight: that it’s possible to train our immune system to be more resilient, rather than just giving it a temporary boost.
Investing in lasting foundational health
Inspired by world-renowned immunologist, Dr. Netea, and his pioneering work on ‘trained immunity’, we set out to build the first family-wide multivitamin that does more than fill gaps— we wanted to strengthen the body’s frontline. We partnered with top medical experts, scientists, and manufacturing partners to formulate our byMae® multi+ immunity training products.
Why immunity training matters
Your immune system doesn’t just protect against colds and flu—it impacts your energy, recovery, digestion, allergies, and resilience every day. A trained immune system responds smarter, adapts faster, and reduces unnecessary inflammation. byMae shifts daily health from temporary solutions to lasting strength—helping you stay ready for whatever life brings.
Real-life tested, mom-founded, expert-backed
Our name might come from moms, but this is bigger than parenting—it's about stronger health for everyone. Welcome to the new standard. Welcome to byMae.
