Review Analysis Results
Analysis Summary
The review set shows moderate signs of inauthenticity with several concerning patterns. Positive reviews (5★) dominate (73% of total), many using similar enthusiastic language about effectiveness against colds/flu with specific dosage instructions. Multiple reviews mention long-term usage (3+ years, 10+ years) which seems coordinated. There's a clear polarization between extremely positive 5-star reviews and negative 1-2 star reviews, with few moderate ratings. Several reviews contain nearly identical phrasing about 'taking when feeling run down' and specific dosage recommendations. The negative reviews raise legitimate concerns about product consistency and ingredient discrepancies, suggesting potential counterfeit issues. However, some reviews show natural variation in writing style and specific personal experiences that appear genuine.

Understanding This Analysis
What does Grade D mean?
This product has significant review authenticity issues. Many reviews show patterns consistent with fake or incentivized reviews. Exercise caution.
Adjusted Rating Explained
The adjusted rating (3.00 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 (3.86 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.
