Review Analysis Results
Analysis Summary
The review set shows mixed authenticity signals. Positive indicators include: natural variation in review length and content, specific product complaints from negative reviewers, and reasonable verification rates. Concerning patterns include: extremely high 5-star concentration (14/16 reviews), several overly generic/vague positive reviews lacking substance, and some suspiciously enthusiastic language in Spanish and English reviews. The negative reviews appear genuine with specific product complaints about dosage confusion and labeling issues, which adds credibility to the overall review ecosystem. The moderate fake percentage reflects that while there are some suspicious patterns, many reviews show authentic characteristics and the presence of genuine negative feedback suggests this isn't a heavily manipulated product.

Understanding This Analysis
What does Grade C mean?
This product has moderate review authenticity concerns. A notable portion of reviews show suspicious patterns. Consider reading reviews carefully before purchasing.
Adjusted Rating Explained
The adjusted rating (3.80 stars) represents what we estimate this product's rating would be if fake reviews were removed. This product's adjusted rating is lower than Amazon's displayed rating (4.40 stars), suggesting positive fake reviews may be inflating the score.
How We Detect Fake Reviews
Our AI analyzes multiple factors: language patterns (generic vs. specific), reviewer behavior (history, timing), temporal anomalies (review clusters), verification status, sentiment authenticity, and statistical outliers. No single factor determines a review is fake - we look at the combination of signals.
Important Limitations
No automated system is perfect. Sophisticated fake reviews can evade detection, and some genuine reviews may be incorrectly flagged. Use this analysis as one data point in your purchasing decision, not the only factor. Reading actual review content yourself is always valuable.
