Nicotinamide Mononucleotide
Another NAD+ precursor and 'NAD+ booster'. Animal studies suggest health benefits in metabolic health, heart function, and cognition. A study also showed it accelerated cancer growth in a specific context.

175 - The biology of aging, rapamycin, and other interventions that target the aging process
Peter Attia MD
An NAD+ precursor or booster, gaining popularity for its potential to increase NAD+ levels. Similar to NR, its efficacy and reproducibility in studies are inconsistent.

#46–Chris Masterjohn, Ph.D.: Pathways to health and disease (NAD, sirtuins, methylation, choline...
Peter Attia MD
An NAD+ precursor, suspected to be non-absorbable intact due to its charged phosphate group, likely cleaved to NR or nicotinamide before absorption.

The Life-Extension Episode With Dr. Matt Kaeberlein | The Tim Ferriss Show
Tim Ferriss
An NAD+ precursor, similar to NR, with ongoing debates about its bioavailability and efficacy, and no lifespan studies in mice yet by the ITP.

#70–David Sinclair, PhD: How cellular reprogramming could slow our aging clock, & the latest on NAD
Peter Attia MD
A molecule that NR is converted into inside cells before becoming NAD+, also a direct precursor to NAD+ being studied for its effects.

Peter Attia MD
An oral NAD+ precursor, similar to NR, that also primarily converts to nicotinic acid (niacin) in the gastrointestinal tract and is considered a niacin prodrug.

Peter Attia MD
A precursor to NAD+, discussed as a longevity-boosting supplement, but with theoretical risks related to potentially favoring tumor metabolism, based on pilot studies in mice.

The Diary Of A CEO
A precursor to NAD+ (Nicotinamide Adenine Dinucleotide) that Dr. Sinclair takes daily to raise NAD+ levels in the body, which fuels sirtuins for cellular repair.
