Review Analysis Results
Analysis Summary
The reviews show a mixed pattern with legitimate concerns about product quality issues (multiple reports of clumping/rock-like powder) alongside some suspiciously positive reviews. The rating distribution is polarized with 8 five-star reviews and 5 one/two-star reviews, suggesting potential review manipulation. Several positive reviews mention specific medical conditions (fibromyalgia, CFS) and dramatic benefits that could be exaggerated. However, the detailed negative reviews about quality control issues appear genuine and specific. The presence of verified purchases and detailed negative feedback about actual product problems suggests a real product with some potentially inflated positive reviews.

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 (2.80 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 (3.20 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.
