How NAD Supplements Work in the Body

NAD supplements work by restoring depleted NAD+ levels within cells, supporting everything from mitochondrial output cellular metabolism to gene expression. While the body naturally makes NAD from dietary sources, this process slows down significantly with age.

NAD IV therapy is another method of supplementation, known for its rapid effectiveness and professional administration requirements.

NAD precursors include:

  • Niacin (Vitamin B3)
  • Nicotinamide mononucleotide (NMN)
  • Nicotinamide riboside (NR)

Once inside the body, these precursors convert to NAD+, helping to reactivate essential cellular functions that keep the body healthy and resilient.

The role of sirtuins:

NAD+ activates sirtuins, a family of proteins responsible for:

  • DNA stability and repair
  • Reducing inflammation
  • Enhancing metabolic efficiency
  • Protecting against oxidative stress

When NAD+ levels drop, sirtuin activity also declines—leading to:

  • Cellular damage
  • Slower metabolic processes
  • Accelerated aging
