Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Written reviews rose from 646 to 678 between September 15, 2025 and August 17, 2026. The largest rise inside any single 30-day window was about 5, so the count moved in steps rather than in one burst.
