Suggested Use

Inside the formula

NR in one transparent, trackable dose.

Nicotinamide riboside is a vitamin B3-related compound used as a precursor in NAD+ metabolism. The label identifies the chloride form and the amount per capsule.

01

Identity

NR chloride

The precise form is named, which matters when comparing label amounts and research.

02

Purpose

NAD+ precursor

NR participates in NAD+ biosynthesis; it is not a source of instant energy.

03

Evidence

Biomarker first

Human trials support changes in NAD+-related measures more clearly than broad anti-aging outcomes.

The NAD+ precursor

Nicotinamide Riboside

β-Nicotinamide riboside chloride

What it is: NR is a nicotinamide nucleoside that can enter the NAD+ salvage pathway after conversion inside the body.

Evidence context: A randomized trial in healthy middle-aged and older adults found oral NR was tolerated and increased NAD+-related metabolites. Broader outcomes were exploratory.

How it fits the formula

A single-active capsule allows NR to be evaluated on its own rather than obscured inside a blend.

Every other label-listed ingredient

What the supporting ingredients actually do.

Rice flour

An inactive carrier that helps achieve a consistent fill.

Cellulose capsule

The plant-derived shell that contains the powder.

The formulation rationale

A clean precursor format.

Named form + declared dose: The chloride form and 500mg amount make comparisons more meaningful than a generic “NAD booster” claim.

Precursor + metabolism: NR must be metabolized through the body’s own pathways; the capsule does not contain NAD+ itself.

Biomarkers + restraint: The strongest direct human signal is NAD+-related biomarker change, not proven lifespan extension.

Each capsule supplies 500mg of beta-nicotinamide riboside chloride, an NAD+ precursor related to vitamin B3 metabolism.
NR can be converted through the NAD+ salvage pathway. Human studies show that supplementation can change NAD+-related blood metabolites, while evidence for broad anti-aging outcomes remains limited.
Evidence tier is identified for each active ingredient
Human, preclinical and formulation evidence are kept separate
Primary-source research is linked in the ingredient breakdown
The exact finished formula is not presented as clinically tested
Shoppers comparing clearly declared active amounts
People who value full inactive-ingredient disclosure
Adults who follow the physical label and review contraindications
Randomized NR trial in healthy middle-aged and older adults
NR increased NAD+-related metabolites and was generally well tolerated in this short-term study. The findings do not demonstrate lifespan extension.

NR can be converted through the NAD+ salvage pathway. Human studies show that supplementation can change NAD+-related blood metabolites, while evidence for broad anti-aging outcomes remains limited.

No finished-product clinical trial is cited. The research links provide ingredient-level context and are labeled by evidence type. This exact finished product has not been clinically tested. The linked study used its own NR material and protocol, so it supports ingredient context rather than guaranteed results.

Label reference: 1 capsule per serving. Follow the physical product label for directions and consult a qualified healthcare professional when appropriate.
