Momentous

Momentous is a supplement company founded in 2018 by Jeff Byers, its CEO, and Erica Good. It is headquartered in Park City, Utah, and operates as Momentous Holdings Corp. In 2024 consumer-focused investment firm Humble Growth took a significant minority stake in the business.

Momentous makes sports and everyday nutrition products such as creatine, grass-fed whey protein, omega-3, magnesium, vitamin D3, fiber and sleep supplements, developed with a network of coaches, nutritionists and doctors. It serves more than 200 professional and collegiate sports programs as well as the U.S. military, sells directly online, and in 2026 expanded into The Vitamin Shoppe and Target stores. The company says every production lot is independently verified, publishes certificates of analysis, and cites NSF Certified for Sport, Informed Sport and IFOS certifications. Dozens of Momentous products, including its creatine, are listed in the NSF Certified for Sport database, and Informed Sport lists Momentous as a certified brand.
