NAD+ (with precursors NMN / NR)
Marketed to support cellular energy metabolism and healthy ageing by raising NAD+ levels
Forms
Capsules of the precursors nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN); some sublingual and IV products are marketed
Advantages
NAD+ is genuinely central to energy metabolism, and precursors can raise NAD+ levels in studies
Disadvantages
Human evidence for real-world anti-ageing or energy benefits is still early and limited; products are expensive; IV forms carry added risk
Side effects
Generally well tolerated short term; mild nausea, fatigue, or headache have been reported
Interactions
Limited interaction data; discuss with a professional if on medication or being treated for a health condition
At-risk groups
People with cancer or serious illness should seek medical advice; long-term use is not well studied
Cautions
Long-term safety is not established; theoretical concerns mean caution in people with cancer; it is not a proven treatment for any condition
