Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Reviews rose from 846 to 897 between February 13 and July 22, 2026 — no sudden jump.

Written reviews rose from 846 to 897 between February 13 and July 22, 2026. The largest rise inside any single 30-day window was about 19, so the count moved in steps rather than in one burst.
