NAD+

Overview

Nicotinamide Adenine Dinucleotide (NAD+) is not a peptide but a coenzyme — a small molecule required as a helper for hundreds of metabolic reactions throughout the body. It's included in this index because of substantial current research interest in its role in cellular aging.

Proposed Mechanism

An essential cofactor for hundreds of metabolic reactions and for sirtuin enzymes implicated in cellular aging. Declining tissue NAD+ with age is well established; restoration strategies are an active area of longevity research.

Research Context

NAD+ levels are well-documented to decline with age across many tissues. Research interest centers on whether restoring NAD+ levels through direct administration or precursor supplementation can meaningfully affect sirtuin enzyme activity — a family of proteins closely tied to cellular aging pathways — and broader markers of metabolic health.

Evidence Status — Well-documented

Well-documented at the biochemical level; clinical outcome data on exogenous administration is still developing.

The biochemical role of NAD+ in metabolism is extremely well-established — this is foundational, decades-old biochemistry, not a novel hypothesis. What's still developing is clinical outcome data specifically on exogenous (externally administered) NAD+ or its precursors, an active and evolving area of longevity research.
