Park City, UT-based performance nutrition company Momentous has debuted Longevity, a dietary supplement designed to support cellular processes with clinically validated ingredients that work synergistically. 

A 3-capsule serving contains 500 mg of Niagen nicotinamide riboside chloride, 600 mg of NAC (n-acetyl-cysteine), 600 mg of betaine anhydrous, 20 mg of PureQQ (pyrroloquinoline quinone disodium salt) as well as vitamin C, and B vitamins.

Each ingredient was chosen for its impact on cellular performance, the company said. Combined, the formulation helps strengthen, regulate, and protect critical cellular processes, including energy production, stress protection, cellular repair, system balance, and brain health, according to the company.

“Longevity works with a synergistic approach to cellular maintenance that supports both brain and body with strength you can count on, balance you can sustain, and resilience that adapts with you,” the company said in announcing the product launch.

Jeff Byers, co-founder and CEO of Momentous, stated: “True longevity isn’t just living longer, it’s living better. Longevity represents our commitment to ‘Performance for Life’ by addressing the foundation of lasting health — your cells.”

He called the formulation “one of the most comprehensive supplements on the market with the best emerging science in cellular health.”

Momentous said its experts chose each ingredient not only for proven individual impacts, but for how they amplify the others, going beyond traditional supplementation and targeting core functions of cellular performance in one daily routine: 

• Metabolic Support & Energy: Niagen and Niacin (B3) support NAD+ levels and aid natural cellular energy production for sustained vitality. 
• Antioxidant Defense & Stress Resilience: NAC, vitamin C, and PQQ strengthen the body’s defenses and stress response. 
• DNA Repair & Protection: B12, betaine, folate (B9), and Niagen support DNA repair processes to boost long-term cellular resilience and promote healthy aging. 
• System Balance: B12, betaine, and folate keep essential cellular processes like detoxification, restoration, and energy regulation balanced. 
• Cognitive Support & Brain Health: Niagen, B vitamins, and PQQ help support mental clarity, memory, and focus while protecting the brain against age-related cognitive decline. 

Longevity is available at livemomentous.com for $109.95. Each 30-serving jar includes 90 capsules, with a recommended daily serving of three capsules taken in the morning or early afternoon. The formula is NSF Certified for Sport, gluten-free, vegan, and GMO-free.
