The labelled three-tablet daily serving provides a conventional supplemental amount of standardized St. John’s wort, but its substantial interaction potential makes this a poor choice without checking medicines with a pharmacist.

Scoring criteria

Quantity
100 / 100
The daily 900 mg of St. John’s wort extract standardized to 0.3% hypericins is within a commonly used supplemental range for this purpose.
Form
75 / 100
St. John’s wort aerial-parts extract is a conventional oral preparation, with no established absorption or tolerability advantage indicated.
Convenience
70 / 100
The directions specify three tablets daily; counted as one daily administration, with the bedtime tablet described as optional rather than additional.
Label accuracy
100 / 100
The labelled 900 mg extract and 2.7 mg hypericins are consistent with the stated 0.3% standardization.
Matches the studied extract
75 / 100
The aerial-parts extract is standardized to hypericins, but the label does not establish a closer match to a specifically studied extract preparation.
Purity
75 / 100
No product-specific purity defect or supported quality-control advantage is provided.
Cofactors
0 / 100
The additional ingredients are declared, but no separately quantified supporting ingredient has a sufficiently established complementary benefit here to earn credit.
