Review Analysis Results
Analysis Summary
The review set shows overwhelming evidence of artificial manipulation with 94% 5-star reviews and clear duplication patterns. Multiple identical reviews appear across different user IDs with the exact same wording, including specific phrases like 'Two-week update: Just one capsule/day' and 'Why did you pick this product vs others?' appearing verbatim 8 times each. The 1-star reviews (6%) show more natural variation and detail about negative experiences, suggesting they may be genuine. The unnatural repetition of positive content, combined with the extreme rating distribution (only 5-star and 1-star reviews with no middle ground), indicates systematic review manipulation rather than organic customer feedback.

Understanding This Analysis
What does Grade F mean?
This product has severe review authenticity problems. A majority of reviews appear fake or manipulated. We strongly recommend finding alternatives.
Adjusted Rating Explained
The adjusted rating (2.60 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 (4.50 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.
