Explore how NAD+ supplementation may support cellular wellness, energy production, and what the research suggests about its potential benefits.*


NAD+ Fundamentals



NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in all living cells. It's absolutely essential for life and plays key roles in energy metabolism.

How NAD+ Works



NAD+ shuttles electrons during cellular respiration – the process that converts food into usable energy (ATP). Without adequate NAD+, your cells can't produce energy efficiently.

Research Highlights*



Studies in animals have shown that boosting NAD+ levels may:
  • Support mitochondrial function

  • Enhance DNA repair mechanisms

  • Improve metabolic health markers

  • Support cognitive function


  • Human research is ongoing, but early results are promising.*

    NAD+ Precursors



    Since NAD+ itself isn't well absorbed, precursors are used:

    NMN


    Converts directly to NAD+ in cells. Increasingly popular in longevity research.*

    NR


    Well-studied precursor with good absorption.*

    Niacin (B3)


    A vitamin that can boost NAD+ but may cause flushing at high doses.

    Practical Applications



    Supporting NAD+ through supplementation and lifestyle may benefit:
  • Energy and vitality

  • Healthy aging

  • Metabolic function

  • Cognitive health
