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

Protocol
- Typical daily doses range from 250 mg to 500 mg, taken orally.
- Often taken in the morning to align with circadian rhythms and energy metabolism.
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.
