Frequently Asked Questions

Tru Niagen® is a food supplement containing Niagen® (nicotinamide riboside, NR), a special form of vitamin B3. Nicotinamide riboside is a precursor of NAD+, a coenzyme found in every cell of the body. The ingredient is patented and authorised as a novel food in the EU and in Switzerland.

NAD+ stands for nicotinamide adenine dinucleotide. It is a coenzyme found in every living cell and is involved in many metabolic reactions, especially energy production in the mitochondria, the “power plants” of the cells. The body makes NAD+ from, among other things, vitamin B3 precursors such as nicotinamide riboside.

The active ingredient of Tru Niagen® is Niagen® (nicotinamide riboside), a special form of vitamin B3 that the body uses to make NAD+. Vitamin B3 contributes to:

  • normal energy-yielding metabolism
  • normal functioning of the nervous system
  • normal psychological function
  • the maintenance of normal mucous membranes
  • the maintenance of normal skin
  • the reduction of tiredness and fatigue

Nicotinamide Riboside has received the approval of the European Union in 2017. The official journal may be reviewed here: Official website of the European Union for novel food appoval

Switzerland and Liechtenstein accepts all the novel food approved by the European Union. There the approval applies as well to Switzerland and Liechtenstein.
