Momentous makes clean, clinically-backed performance supplements — and they back it up with the most rigorous third-party testing program in the industry. Every batch of every product is NSF Certified for Sport®, which means it's independently tested for banned substances, label accuracy, and contamination. Most supplement brands don't test every batch. Momentous does.

That standard is why Momentous is trusted by 100% of NFL teams, used by Olympic athletes, MLB and NHL teams, and U.S. Special Operations units. The U.S. Department of Defense has awarded Momentous multiple innovation contracts for human performance nutrition.

Why we carry Momentous at Living.Fit

We carry a lot of supplement brands. Momentous is one of the few we recommend with no caveats. Three reasons:

  1. Third-party testing on every batch, every product. NSF Certified for Sport® across the whole catalog — including the products most often contaminated in the broader market (creatine, pre-workout, protein powders). If you've ever wondered whether your supplement actually contains what the label says and nothing else, Momentous is the answer.
  2. Branded, evidence-based ingredients. Momentous uses the patented, clinically-studied forms of key actives rather than the cheaper generics: Creapure® creatine, Magtein® magnesium L-threonate, NooGandha® ashwagandha, FORTIGEL® collagen, ProHydrolase® digestive enzymes, Ferrochel® iron, Niagen® nicotinamide riboside, Kaneka Ubiquinol™, and DimaCal® calcium. These are the ingredient forms the research is actually done on.
  3. A real scientific advisory bench. Formulations are developed in collaboration with Dr. Andy Galpin, Dr. Stacy Sims, and other published exercise scientists. The Huberman Lab Podcast partners with Momentous specifically because the formulations match what the research supports.

Featured: The Foundational Stacks

Momentous designed three core stacks specifically for people who want the basics done right without thinking about it:

  • The Momentous Three — Creatine + Whey Protein + Omega-3. The foundational stack every adult should be on.
  • The Momentous Three (Vegan) — Creatine + Plant Protein + Vegan Omega-3. Same evidence-based foundation, plant-based.
  • The Women's Three™ — Formulated specifically for women's physiology and developed in collaboration with Dr. Stacy Sims.
