Outcomes

The evidence for nicotinamide riboside (Niagen) outcomes comes primarily from preclinical studies, with limited human clinical trial data currently available in the literature.

Preclinical Findings

Metabolic and Mitochondrial Effects:

Studies report that nicotinamide riboside boosts mitochondrial function and prevents mitochondrial dysfunction in specific disease models, including nemaline myopathy type 6
Research demonstrates the compound's role in NAD+ homeostasis, with one study developing methods to selectively detect NAD+ and NADH derived from nicotinamide riboside in mouse liver extracts
An integrated analysis suggests potential anti-aging effects through targeting NAD+ homeostasis, mitochondrial quality control, and redox stability

Anti-Inflammatory Properties:

Preclinical research indicates nicotinamide riboside reduces glial inflammation
One study reports that NAD+ augmentation by nicotinamide riboside engages SLIT2/ROBO1 signaling pathways to attenuate Th17 inflammation in psoriasis models

Clinical Trial Evidence

Several completed clinical trials have investigated nicotinamide riboside in humans:

Systolic heart failure (Phase 1/2 trial)
Metabolic health outcomes
Exercise-related effects
Mitochondrial biogenesis

However, the specific measurable outcomes from these completed trials are not detailed in the available evidence. The strength of evidence for human applications remains limited without access to published results from these studies.

Evidence Limitations

The current evidence base has significant gaps:

Most mechanistic and efficacy data comes from preclinical models
Published results from completed human trials are not readily available in the literature reviewed
Long-term safety and efficacy data in humans is sparse
