- What It Does
Nicotinamide Riboside (NR) is a highly efficient NAD+ precursor that supports cellular energy production and healthy aging. As we age, NAD+ levels decline by up to 50%, and NR supplementation helps restore optimal levels for enhanced vitality and longevity.
- How It Works
NR is efficiently converted to NAD+ through the salvage pathway, bypassing several metabolic steps. This supports mitochondrial function, activates sirtuins (longevity genes), enhances DNA repair, and promotes cellular health. NR has excellent bioavailability and is well-studied for its anti-aging benefits.
- Science-Backed Research
Clinically proven to increase NAD+ levels in humans
Supports mitochondrial function and cellular energy
Activates sirtuins, which regulate longevity and metabolism
May improve cardiovascular health and insulin sensitivity
Well-tolerated with extensive human safety data
- Ideal For
Health-conscious individuals over 30
Anyone interested in longevity and healthy aging
Those seeking enhanced energy and mental clarity
People looking to optimize cellular health and NAD+ levels

Frequently Asked Questions
Everything you need to know about our premium supplements
Nicotinamide Riboside (NR) is a highly efficient NAD+ precursor that boosts cellular energy. It's converted to NAD+ through the salvage pathway, supporting mitochondrial function, DNA repair, and activating sirtuins (longevity genes). NR has been extensively studied and is recognized as one of the most effective ways to increase NAD+ levels.
Both NR and NMN are NAD+ precursors, but NR has more extensive human clinical trials and proven bioavailability. NR is converted to NAD+ via a well-established pathway. Our 500mg dose provides optimal NAD+ support with excellent absorption.
Many users report increased energy and mental clarity within 1-2 weeks. Cellular benefits like improved metabolic markers typically appear after 4-8 weeks of consistent use. For optimal longevity support and NAD+ restoration, we recommend sustained daily use of 500mg.
Yes! NR pairs excellently with resveratrol (which activates sirtuins), pterostilbene, and other longevity compounds. Some people also add TMG (trimethylglycine) to support methylation. Our 500mg dose provides comprehensive NAD+ support. Always consult your healthcare provider about your specific supplement regimen.
