This is our obsession.

We never planned to start a supplement company. The way we wanted to do it felt almost impossible, because the industry was crowded with products hiding behind incomplete labels, unnecessary fillers, and formulas that just don’t deliver. We didn’t choose to be a supplement company;we chose to create what didn’t exist.

We started Momentous to bring the best of science to the world—and to push it further. From day one, our goal has been simple: use the highest-quality ingredients available, demand better at every step, and hold every product to the same standard of excellence expected by Olympic athletes and professional leagues.

We’re all high performers—some of us athletes, all of us obsessed with getting more from our bodies, living healthier and longer, and showing up as our best every single day.

We call that obsession The Momentous Standard—our code, our compass, and the benchmark behind every decision we make.

Keep pushing.

Science in action.

We partner with the leaders in human performance—elite athletes, world-class coaches, top Ph.D.s, cutting-edge research labs, and government institutions. Together, we’re advancing the science of what the human body is capable of. From foundational research to clinical studies to hands-on work with our customers, we’re committed to turning breakthrough science into real-world impact.

Only the essentials.

We use the highest-quality ingredients available and formulate with the latest science on what truly works. No vague claims. No hidden “proprietary blends.” If it’s in our formula, it’s on our label—fully transparent, every time. We source from best-in-class partners and hold them to the same rigorous standards we set for ourselves, auditing every step of their production to ensure uncompromising quality.

Rigorous testing.

Momentous products are held to the standards set by the most demanding organizations in the world—including the NFL, WNBA, NBA, MLB, and the Olympic Committee. This level of scrutiny is our ultimate quality check, ensuring that every batch we produce meets the same uncompromising standard. No shortcuts, no exceptions—just products that deliver exactly what we promise.

"The proof is in the people we work with from professional organizations and teams, billion-dollar companies, the U.S. military, and top experts and advisors in the world."
