Founded by a former NFL lineman. Held to the standards of the NFL, NBA, MLB, WNBA, and the Olympic Committee. Every batch tested, every label honest, every formula backed by the best science available — that's the Momentous Standard, and it's exactly the bar Nutrition Locker exists to defend.
Momentous is the Park City, Utah–based human-performance brand that didn't set out to be another supplement company — and then built one anyway, because no one else was doing it the way they thought it should be done.
The company is led by co-founder and CEO Jeff Byers, a former NFL offensive lineman who came up through pro and college locker rooms watching athletes get handed products that hid behind incomplete labels, proprietary blends, and marketing dressed up as science. Momentous was built as the answer to that — a product line designed against the standards used by the NFL, NBA, MLB, WNBA, and the U.S. Olympic Committee, with NSF Certified for Sport and Informed Sport certifications across the core lineup, and Certificates of Analysis published openly.
Today Momentous partners with USA Rugby's men's and women's national teams, sits in the supplement programs of dozens of pro and collegiate organizations, and works with a roster of human-performance experts including Dr. Andy Galpin, Dr. Andrew Huberman, and others. The science isn't a marketing layer; it's the operating system.
Most of the supplement industry isn't built for the people we serve. Most of it is built for shelf space — proprietary blends, vague claims, sub-clinical doses, ingredients sourced from the cheapest mill that day. The brands that actually do the work — that spend the time, the money, and the discipline to make a product an RD can hand to an athlete without a follow-up call — are the exception, not the rule. Momentous is one of those exceptions.
Momentous calls their internal code The Momentous Standard — three pillars: science in action, only the essentials on the label, and rigorous testing against the most demanding leagues in the world. They aren't marketing copy. They're the operating system the company is built on.
It's also exactly what Nutrition Locker is built to defend. We don't stock supplements that hide behind proprietary blends. We don't stock under-dosed formulas dressed up in clean-label graphics. We don't stock anything that isn't certified to a standard a pro or Olympic compliance officer would recognize. There are a lot of supplement companies. There are very few who do it right. Momentous does it right — and that's why they're in the Locker.
Partnered with leading PhDs, research labs, government institutions, and elite athletes — translating foundational research and clinical studies into formulas that actually move outcomes. Not citations bolted onto marketing.
Highest-quality ingredients, current science, transparent labels. No vague claims. No proprietary blends. If it's in the formula, it's on the label — fully disclosed, fully dosed.
Held to the standards set by the NFL, NBA, MLB, WNBA, and the Olympic Committee. Every batch tested. NSF Certified for Sport and Informed Sport across the core line. Certificates of Analysis published.
On top of the Standard, here's the operational case for keeping Momentous in heavy rotation:
The supplement industry produces a lot of products that aren't safe, aren't clean, aren't dosed, and aren't tested. We don't stock them. We stock brands that do the expensive, slow, careful work — research, batch testing, full-label disclosure, third-party certification — and we point our RDs at the catalog with confidence. Momentous is on the short list of vendors who clear that bar without an asterisk.
Only NSF Certified for Sport and Informed Sport SKUs from Momentous appear in the Locker. Featured highlights below; the full Momentous certified catalog ships through the Locker once an account is active.
The non-negotiable trio: creatine for performance and cognition, whey protein isolate for protein adequacy and recovery, omega-3 for inflammation and brain health. The simplest place to start with an athlete who hasn't built a baseline yet.
Creapure®-grade creatine monohydrate, NSF Certified for Sport, dosed at the standard 5 g. Unflavored, easy to stack into any shake or hydration mix. The most-used SKU in the catalog and the one most teams default to.
A no-shaker, no-water-needed creatine format — purpose-built for road trips, mid-day dosing, and athletes who won't actually mix a powder. Removes the #1 reason creatine compliance falls off mid-season.
Grass-fed whey protein isolate from European dairy partners, dual-certified, with a clean amino profile. The workhorse protein in the Momentous line — mixes cleanly, fits into post-training recovery, smoothies, and oats.
Pea + rice protein blend designed to deliver a full essential amino acid profile — built for vegan, dairy-intolerant, or rotation-protocol athletes who still need a certified, full-disclosure protein source.
High-dose, third-party-tested EPA/DHA fish oil for inflammation management, recovery, and cognitive support. NSF Certified for Sport — one of the few certified omega-3 SKUs at a meaningful dose.
The only magnesium form clinically shown to cross the blood-brain barrier in meaningful amounts — used for sleep quality, cognitive support, and stress management. NSF Certified for Sport, which is rare in the magnesium category.
A travel-friendly nightly sleep stack combining magnesium, L-theanine, and apigenin — designed for road games, time-zone travel, and any athlete whose recovery is bottlenecked at sleep.
"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."
