Same category, higher SupplementScore. Based on dosage transparency, label cleanliness, and formula quality.
The research summaries below are about the ingredients in general, drawn from published studies that often use different doses, forms, and populations than this product. A "strong" evidence rating for an ingredient does not mean this product will produce that effect — studied doses may be significantly higher or lower than what is contained here. Always verify doses against the Supplement Facts table above.
Multiple RCTs show cortisol reduction and improved stress/anxiety scores, primarily with standardized extracts (KSM-66, Sensoril) at 300-600mg/day.
Limited evidence for testosterone effects, primarily in stressed or subfertile men using KSM-66 extract. Results in healthy men are inconsistent.
May improve VO2 max, strength, and recovery. Typically studied at 300-600mg/day of standardized root extract (KSM-66 or equivalent).
