Benefits at a Glance

Now with twice the amount of nicotinamide riboside

  • increases the body's ability to produce energy
  • supports cognitive function and provides neuroprotection
  • supports healthy metabolic function, including insulin
  • sensitivity and nutritional support for fatty liver
  • promotes healthy aging through sirtuin activation

Nicotinamide riboside (NR) is the most direct precursor to nicotinamide adenine dinucleotide (NAD+). NAD+ is a key component of the citric acid cycle and the electron transport chain, both involved in mitochondrial production of ATP for energy.

In addition to its importance in cellular energy production, NAD+ is a critical substrate for several enzymes, including sirtuins (SIRT1 and SIRT3, in particular), which play key roles in healthy aging, weight management, metabolic syndrome, and hepatic lipid metabolism.

What health benefits does NiaCel provide?

  • NiaCel supports insulin sensitivity
  • NiaCel promotes healthy aging by turning on sirtuins, which increases mitochondrial biogenesis
  • NiaCel is neuroprotective and supports cognitive function
  • NiaCel supports weight management by promoting thermogenesis
  • NiaCel benefits endurance athletes and fatigued individuals by increasing muscle and cardiac mitochondria




Why take Nia-Cel?

Nicotinamide riboside, along with nicotinic acid and tryptophan, are precursors for nicotinamide adenine dinucleotide (NAD). NR is metabolized into nicotinamide mononucleotide (NMN) once inside the cell, by a phosphorylation step catalyzed by the nicotinamide riboside kinases (NRKs), which in turn is converted into NAD+.


  • Source of the essential vitamin niacin (Vitamin B3)
  • Helps make nicotinamide adenine dinucleotide (NAD(+)) in the body, which helps supply us with energy and improves cellular health.
  • May help decrease oxidative stress in the brain and improve nerve function
  • May help prevent damage to the brain due to trauma, including military, sports and recreational injuries.
