Product analysis

63 out of 100

St. John's Wort 300 mg offers focused herbal mood support, with benefits that depend on the preparation and individual situation. It can interact with many medicines, including contraceptives and blood thinners, so a pharmacist should check whether it is suitable for you.

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

Nutrient Quality40

The extract is identified, but its quality cannot be compared confidently from the available detail. Naming a constituent alone does not establish equivalence with other extracts.

Ingredient Transparency100

The amount and named extract detail are disclosed. That makes the contents easier to identify when comparing preparations.

Value For Money40

There is not enough information to judge value confidently. A clear amount alone does not establish whether the extract is worth its cost.

Customer Satisfaction88

Customer ratings are strongly positive. The large review base gives a broader picture of customer satisfaction.

Product Focus67

The single herb keeps the formula focused on mood support. The serving is below the daily amounts in much of the relevant evidence, and benefits for healthy adults remain uncertain.
