Our story

Gut health should feel precise, not performative.

No sleep gummy. No beauty gummy. No gut shot. One daily super greens jar, dosed at the level the studies actually used.

Mango and Berry, same foundation

Origin

Two flavors, one focused formula.

Biome Theory was founded in 2025 by two people brought together by a shared passion for wellness, balance, and building something meaningful for the community. Co-founded by Rania O., with a background in physics, neuroscience, and neurobiology, the brand was inspired by years spent studying science, human health, and the connection between everyday habits and long-term wellness.

While on the path toward healthcare, Rania realized her passion extended beyond traditional medicine. She became deeply interested in the idea that wellness is shaped not only inside clinics or hospitals, but through the small routines, habits, and choices people make every single day. That perspective became the foundation behind Biome Theory — creating products that feel intentional, approachable, and realistically sustainable for everyday life.

Alongside her is Chris, whose background in finance and energy management brings the strategic and analytical foundation behind the long-term vision of Biome Theory. Passionate about health, performance, and personal growth, he always envisioned building a product that could positively impact people’s everyday routines in a realistic and sustainable way. Together, their goal was to create a brand that blends thoughtful formulation, elevated wellness, and a genuine connection to the people using it.

Biome Theory was created to support modern wellness in a way that feels approachable, balanced, and sustainable. From the ingredients to the experience itself, every detail was designed with intention — not to overcomplicate wellness, but to make it something people genuinely enjoy returning to every day.

In the press

Quietly recommended.

We don't pitch supplement-of-the-week roundups. These are publications that read the label first.

  • Reads more like a chemistry brief than a wellness pitch.
    Vogue, Wellness desk
  • The label is the loudest thing about it, and even that whispers.
    Goop, Beauty desk
  • A flavor system you can actually keep up with for a full thirty days.
    Bon Appetit, Test Kitchen
  • One of the most measured supplement launches we've covered this year.
