- Review of studies
A 2026 systematic review of 113 studies (33 in people, 80 in rodents) found that in people NR and NMN consistently raised NAD-related markers in blood or cells, but effects on functional, metabolic, vascular and other health outcomes were mixed and often absent.

How to track it in Peptimes
Add nicotinamide riboside in My Protocols and set the schedule you already follow: days of the week, times of day and a start date. Peptimes never suggests an amount when you log or schedule a dose. Its Library entry is called “NR (Nicotinamide Riboside)” and shows the status label “Dietary Supplement”. It is a separate Library entry from NMN and NAD+.
- Logging: the amount you took and how you feel. It’s logged as oral, so there’s no injection site to record.
- Reminders and history: reminders at your times, Dose History, the Calendar and CSV or JSON export work as described on the peptide tracker app page.
Peptimes is a tracking app, not medical advice. Talk to a licensed clinician about your treatment. Peptimes doesn’t sell nicotinamide riboside or any other compound.
