Your cells rely on NAD+ for energy metabolism, and levels fall as you age. NMN is the compound your body uses to make it. Each serving delivers 500 mg of ß-Nicotinamide Mononucleotide at 99.9% purity, a direct way to support NAD+ production as part of a daily routine.

Made for people running demanding days: long hours, early starts, and training that doesn't stop because work got busy. By supporting NAD+ biosynthesis, NMN supports cellular energy production, normal metabolic function and normal cellular function.*

Benefits of Daily Use

Consistency matters with a longevity supplement. Here's what a daily routine supports.

Support NAD+ at the source - NAD+ levels decline with age, and NMN is a direct precursor your body converts into NAD+.*

Support how your cells make energy - NMN supports normal cellular energy metabolism.*

Build a foundation for healthy aging - One capsule a day to support your cells for the long run.*

Frequently Asked Questions

ß-Nicotinamide Mononucleotide (NMN) is a naturally occurring compound that serves as a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide), a coenzyme essential for cellular energy metabolism and numerous biological processes. By supporting your body's natural NAD+ production, NMN helps maintain the cellular function that underpins daily energy, normal metabolic function, and healthy aging.*

NMN is absorbed by the body and converted into NAD+ through your natural biosynthesis pathway, making it one way to support NAD+ levels at the source. Both approaches have merit, and some individuals choose to take both as part of a comprehensive longevity-focused routine.*

We recommend taking one capsule daily in the morning with 6-8 oz of water. Many people prefer mornings as an easy habit to keep. What matters most is taking it consistently at the same time each day.

BioSempra NMN is third-party tested by an independent laboratory to verify purity and safety. Our NMN has a purity of 99.9%, meaning you get the highest quality NMN.

NAD+ levels naturally decline with age, and lower NAD+ is associated with reduced cellular energy production. NMN is a direct precursor your body converts into NAD+, so supplementing supports your body's own production pathway. That's why NMN has become a common part of longevity-focused routines.*

Reallt nice supplement

Awesome

i tried the powder form first, but it was hard to measure accurately and tasted bitter. the tablets are much more convenient. i take 100mg in the morning, and it sustains my energy through my workday without the caffeine jitters.
