What the research says
1 study reviewedSupporting (1)
Randomized Controlled TrialHuman2026
In people with two copies of the APOE4 gene — who are at high risk for Alzheimer’s — a pill called obicetrapib stopped a key brain damage marker from rising and even made it go down, while the placebo group got worse. This suggests the pill may help protect their brains.

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.
A drug blocks a protein that moves cholesterol between blood particles, causing more healthy cholesterol particles to enter the brain. These particles clean up excess cholesterol and toxic fats from brain cells, reduce harmful oxidative stress, and stop a key brain protein from becoming abnormally modified. This prevents brain damage signals from rising in people with a genetic risk for Alzheimer's.

- 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.
