Source Naturals Serene Science Theanine Serene with Magnesium - 60 Tablets

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.

The chemical forms of magnesium and the other active ingredients are not disclosed, leaving relevant absorption and tolerability properties unresolved.

The label directs two tablets once daily, and 60 tablets provide 30 labeled servings.

The matched label provides consistent ingredient amounts and directions, but it does not identify the chemical forms or standardization of several ingredients.

The ingredients are broadly compatible at the labeled amounts, although the formula does not disclose detailed extract standardization or chemical forms.

The label shows ordinary excipients and provides no product-specific evidence supporting unusually high purity or documenting contamination.

Holy basil extract is declared at a meaningful amount and may complement the calming formula, but its preparation and added benefit are uncertain.
