NMN / NR (NAD+ precursors)

nicotinamide mononucleotide ยท nicotinamide riboside ยท NAD+

Reliably raises blood NAD+; whether that translates into human health gains is open after a couple of small positive and several null RCTs.

2/5Estimated monthly cost: โ‰ˆ 40 โ‚ฌ
Dose

250โ€“600 mg NMN or 300โ€“1,000 mg NR daily (trial doses).

Timing

Morning.

โš  Cautions

What it is

Precursors of the coenzyme NAD+, which falls 30โ€“50% with age in some tissues.

What the evidence shows

Yoshino 2021 (n=25, prediabetic women, 250 mg NMN, 10 weeks): improved muscle insulin sensitivity. Yi 2023 (n=80): NMN 600โ€“900 mg improved the 6-minute walk. Several NR RCTs (muscle, metabolism) were neutral. No hard endpoints.
