Description:

Cost for a one-month supply of a reputable brand; not covered by insurance.

Summary

Nicotinamide adenine dinucleotide (NAD+) is a vital coenzyme for cellular metabolism and DNA repair whose levels decline with age. This intervention uses a liposomal delivery system, which encapsulates NAD+ molecules in lipid spheres. This is purported to protect the molecule from degradation in the digestive tract and enhance its absorption into cells, potentially increasing bioavailability compared to other NAD+ precursors.

Purpose

Boosts cellular NAD+ levels to support energy and repair.

Card Summary

An oral supplement designed to increase cellular NAD+ levels, which decline with age, by using a lipid-based delivery system for enhanced absorption.

Impact

Score:

3.8

Justification:

Theoretically potent, but lacks robust human data demonstrating significant healthspan extension.

Evidence

Grade:

C

Score:

3.5

Justification:

Human trials show precursors raise NAD+ levels, but evidence for healthspan outcomes is limited.

Safety

Score:

3

Justification:

Generally well-tolerated in short-term human studies with mild, infrequent side effects reported.

Flags

• Long-term safety data in humans is still limited.
• Claims of superior bioavailability for liposomal forms often lack independent, third-party verification.
• Some research suggests high NAD+ levels could potentially fuel certain cancers, though this is debated.
• Quality and dosage can vary significantly between unregulated supplement brands.

Verdict

A promising but speculative strategy to boost a key aging-related molecule.
