This is a compact, adequately dosed multi-ingredient calming formula, but its undisclosed magnesium form limits form confidence.

Criterios de evaluación

Quantity
100 / 100
The labeled daily serving supplies 300 mg magnesium, 200 mg L-theanine, 500 mg GABA, 450 mg taurine, and 100 mg holy basil extract, which is a practically substantial calming formula.
Form
65 / 100
The chemical forms of magnesium and the other active ingredients are not disclosed, leaving relevant absorption and tolerability properties unresolved.
Convenience
85 / 100
The label directs two tablets once daily, and 60 tablets provide 30 labeled servings.
Label accuracy
75 / 100
The matched label provides consistent ingredient amounts and directions, but it does not identify the chemical forms or standardization of several ingredients.
Formula balance
75 / 100
The ingredients are broadly compatible at the labeled amounts, although the formula does not disclose detailed extract standardization or chemical forms.
Purity
75 / 100
The label shows ordinary excipients and provides no product-specific evidence supporting unusually high purity or documenting contamination.
Cofactors
50 / 100
Holy basil extract is declared at a meaningful amount and may complement the calming formula, but its preparation and added benefit are uncertain.
