Study snapshot

Design	Validated HPLC-DAD/UV analysis with LC-MS/MS confirmation
Model	Common plant foods and non-conventional Amazon plant foods
Sample	Plant-food samples; no human supplementation participants
Intervention	Measurement of NR, NMN and NAD+ in fresh-weight food samples
Duration	Laboratory analytical study
Endpoints	NR concentration; NMN concentration; NAD+ concentration; Analytical validation

What the study showed, in plain terms

This analytical study measured NR, NMN and NAD+ separately in plant foods rather than treating total vitamin B3 as NR.

Key findings

The publisher summary reports NR concentrations ranging from 62 to 1600 micrograms per 100 g fresh weight, with wild chicory, banana and orange among the higher-NR foods tested.

What this study can and cannot tell us

Composition varies by sample and method. Food concentration does not establish absorbed exposure or a clinical anti-aging benefit, and NMN concentrations must not be relabeled as NR. Exact food-specific numerical tables were not verified for this summary.
