Product analysis

53 out of 100

St. John's Wort 300 mg is aimed at mood support, but effects depend on the exact extract. It can weaken contraception and other medicines, making compatibility important before use.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality36

The St. John's wort marker is identified, but it does not fully establish the extract preparation. Rosemary and blue-green algae have less complete source details, leaving their quality uncertain.

Ingredient Transparency75

All ingredient amounts are listed, and St. John's wort has a named marker. Rosemary and blue-green algae lack stated forms, limiting a fuller comparison.

Value For Money40

Value for the main herb and the added ingredients cannot be judged confidently. The available cost and preparation details do not support a reliable comparison.

Customer Satisfaction70

Customer feedback is generally positive. A sizeable set of reviews supports that impression, without proving effectiveness or safety.

Product Focus57

Mood effects depend on the exact extract and are not established as a dependable everyday lift. Important medicine interactions include reduced contraceptive effectiveness and problems with serotonin-raising combinations.
