Analysis Summary

The review set shows mixed authenticity signals. Positive indicators include: natural variation in review length and detail, some negative/neutral reviews (1-star and 4-star), and generally plausible supplement experiences. Concerning patterns include: high 5-star concentration (13/15 reviews), several overly enthusiastic reviews with marketing-like language, repetitive 'tingle' mentions that could indicate coordinated messaging, and some very brief generic reviews. The duplicate review (R1CWGQXSXQ4Z9Y appearing twice) is particularly suspicious. However, the presence of legitimate negative feedback and detailed personal experiences balances the assessment toward moderate rather than high fake percentage.

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 (4.00 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 (4.67 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.
