No numeric quantity is printed on 3 organism rows of the latest observed label; potency basis The potency basis is not stated. 3 rows sit inside a proprietary blend, so their individual amounts are not disclosed.
Evidence behind the label
Located human trials per organism
Organism on this label
PubMed records indexed as human randomized controlled trials
Counts describe records matching each organism's published query, including trials of multi-ingredient products; they are not a count of trials of this product.
Context
Where this score sits
This formulation scores above 6.3% of the 4,101 scored formulations in this release. The score is a preference-dependent summary of the axes, not a health claim.
Evidence queries are incomplete. A2 uses the known matching records as a lower bound.
Scored using the available matching evidence. Identity: A commercial strain code is printed. Quantity disclosure: 0.0%. Potency: The potency basis is not stated.
Axes 3–4
