Scoring criteria

Quantity
100 / 100
Two tablets provide reasonable general supplemental amounts of the principal calming ingredients for the stated stress-support role.
Form
65 / 100
L-theanine, GABA, and taurine are identified, but the magnesium compound and the specific Relora and holy basil extract forms remain unresolved.
Convenience
85 / 100
The label directs two tablets once daily, and the container provides 120 tablets.
Label accuracy
75 / 100
The matched label provides internally consistent quantities and directions without an established contradiction.
Formula balance
75 / 100
The formula covers several plausible calming pathways at declared amounts, but no established synergy or extract standardization supports a higher balance mark.
Purity
75 / 100
The disclosed excipients are ordinary for tablets, while no product-specific testing or contaminant evidence is provided.
Cofactors
0 / 100
The declared ingredients are assessed as co-primary formula components rather than separate supporting cofactors.
