NAD+
Also known as: Nicotinamide adenine dinucleotide
A coenzyme found in every cell that helps turn food into energy; it is not a peptide, but it is commonly sold and discussed alongside them.
Overview
NAD+ is a molecule present in every living cell. It is essential for energy production and is used by enzymes involved in DNA repair and cell signaling. Unlike the other entries in this library, it is not a peptide, but it is included because it is frequently sold and discussed in the same market.
What the research has looked at
Studies in animals and some human tissue have reported that NAD+ levels fall with age. This has driven research into precursor supplements such as nicotinamide riboside and nicotinamide mononucleotide, which can raise NAD+ levels in blood.
What we do not know
- Raising NAD+ in the blood has not been shown to slow aging or improve health outcomes in people.
- There is little controlled evidence for injectable or IV NAD+ products.
- Most human trials of precursors are small and short.
Regulatory context
NAD+ is not approved as a treatment for aging. Rules for precursor supplements differ by country and have changed over time.
