The Gold Standard
Uthever® NMN is the ultimate NAD+ precursor and an essential building block in the NAD+ synthesis pathway*

NAD* (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell of your body, essential for converting nutrients into energy, activating DNA-repair enzymes (PARPs), and regulating sirtuins—proteins that influence gene expression and longevity. As a cornerstone of cellular metabolism, NAD* supports energy production, DNA integrity, and healthy aging.*
By middle age, NAD* levels in some tissues can drop by up to 50%, slowing down cellular repair and metabolic efficiency. One of the most effective ways to maintain NAD* is with Nicotinamide Mononucleotide (NMN)—a clinically studied form of vitamin B3 that supports the body’s natural NAD* production pathways, helping you feel energized, resilient, and more youthful as you age.*

Nicotinamide Mononucleotide (NMN) is one of the most promising breakthroughs in longevity science. As a powerful vitamin B3 derivative and direct NAD+ precursor, it helps fuel the cellular energy, repair, and resilience needed to promote healthy, vibrant aging.*

As we age, NAD+ levels naturally decline, making replenishment essential to support core longevity processes. NAD+ targets the root causes of aging, fueling essential enzymes like PARPs, which repair DNA and maintain cellular integrity, and activating Sirtuins, which regulate gene expression, inflammation, and stress response—key contributors to healthy aging.*
To maintain peak performance, your body requires a steady supply of NAD+. With NMN, you can effortlessly and continuously support your NAD+ levels. Research demonstrates that supplementing with NMN can elevate NAD+ levels in a dose-dependent manner, meaning higher doses yield greater increases in NAD+ concentrations.*
NAD+ plays a vital role in converting food into usable energy at the cellular level. With NMN, you can optimize ATP production, leading to enhanced energy availability throughout the body. This boost in cellular energy not only supports physical performance but also contributes to enhanced quality of life.*

Both NMN and NR raise NAD+ levels. NMN is one enzymatic step closer to NAD+, while NR first converts to NMN before becoming NAD+. Some users report subjective differences in response. Human data support NAD+ increases from both, though study designs and doses vary.*
Human studies have used daily NMN doses ranging from 250 mg to 2000 mg. Lower doses focus on long term consistency and tolerance. Higher doses are used in clinical research settings and advanced protocols. Dose selection depends on goals, age, activity level, and stacking strategy.*
Changes in NAD+ levels occur before subjective effects. Some users report changes in energy, exercise recovery, or sleep within weeks. Others notice benefits only after sustained use. Individual response varies.*
Lower daily doses support steady NAD+ precursor availability over time. Higher doses increase total substrate availability but are not required for every user. Consistency matters as much as dose for long term NAD+ maintenance.*
NMN works with or without food. Some users prefer fasted dosing for metabolic signaling, while others prioritize comfort and tolerance. Morning dosing aligns with circadian NAD+ rhythms and daytime energy metabolism, though evening dosing works for some without affecting sleep. Timing does not prevent conversion to NAD+, so individual response should guide both food and time of day choices.
