What is it?
NAD+ is a coenzyme used in cellular energy transfer and other biochemical reactions. It is not a peptide. Its essential role inside cells is distinct from the evidence for administering it as a wellness intervention. [1]
Potential benefits
Essential coenzyme in cellular redox and energy metabolism. Its biological role across tissues is well established. [1]
Evidence & its limits
The pilot’s small, male-only sample and short observation period cannot establish long-term clinical benefit or uncommon risks. The paper also discloses financial and clinical ties to NAD+ services. Methods and conflict disclosures . [1]
Risks & unknowns
NAD+ is not a peptide. Biological importance does not prove broad benefits from every injection, infusion, supplement, or wellness claim. [1]
Status & scope
NAD+ is a coenzyme, not a peptide. Its essential cellular role does not establish benefits from administering a particular infusion, injection or supplement. [1]
