This score evaluates label quality — dosage disclosure, transparency, cleanliness of inactive ingredients, and formula composition. It does not measure clinical efficacy, bioavailability, or third-party testing. Read full methodology
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.
Zinc is a cofactor for over 300 enzymes involved in immune cell development and function. Supplementation may reduce duration of common cold symptoms, particularly as lozenges. Essential for maintaining immune barrier integrity.
Essential for skin integrity and wound repair processes.
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).

Alternatives are selected from the same category (Protein Supplements) with a higher overall score. This is not a recommendation — always verify ingredients and dosages match your needs.
Essential for calcium absorption. Deficiency leads to rickets in children and osteomalacia in adults — a well-established causal relationship.
May reduce risk of respiratory infections. Active area of research.
Some association between low vitamin D levels and depression, but evidence is inconsistent.
May support cardiovascular health by influencing triglyceride levels. Effect is dose-dependent (typically studied at 1-4g EPA+DHA/day).
EPA and DHA have anti-inflammatory properties through multiple pathways. Effects are dose-dependent, typically studied at 1-3g combined EPA+DHA/day.
DHA is a structural component of brain tissue. Supplementation may support cognitive health, primarily studied at 500-1000mg DHA/day in older adults.
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).
