Experiments in mice have identified a specific biological pathway that connects the vitamin niacin to Alzheimer's disease. This suggests niacin plays a role in the disease process, though whether it is protective or harmful is not specified.
See the scientific wording
Mouse model studies demonstrate a biological mechanism linking the vitamin niacin to the pathogenesis of Alzheimer's disease.
Correlational — new studies may shift this
One low-scoring study links this claim to the outcome, but causation is not established.

Supplementation with NAD+ and Its Precursors to Prevent Cognitive Decline across Disease Contexts
Narrative ReviewReview2022
This review shows that giving mice supplements related to niacin (like NMN and NR) helps protect their brains and memory in Alzheimer's models, which supports the idea that niacin is linked to the disease through a biological pathway.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

How Fit Body Science checks a claim
- 1
We isolate the claim
Health advice from videos, articles and studies is broken down into single, testable claims.
- 2
We find the research
Each claim is matched against peer-reviewed studies, with every source cited by DOI.
- 3
We grade the evidence
Studies are scored on methodology, statistical rigor, transparency and publication quality.
The fitness and health internet is full of confident claims. We check them against real research.
Every claim on this site is traced back to peer-reviewed studies, scored on methodology and reporting quality, and given a verdict you can audit yourself — sources, DOIs and all.
