Supplement
Effectiveness scores 82 due to multiple RCTs (e.g., 200mg L-Theanine reduced salivary alpha-amylase stress marker by 20-30% vs. placebo) and meta-analysis support for anxiety relief, matching product dose. Safety is near-perfect (97) as L-Theanine has excellent tolerability profile in trials up to 1200mg/day with no serious events. Quality at 75 reflects GMP/transparency but lacks consumer-facing seals like USP; overall 84 indicates reliable stress aid but not top-tier certified.
