Perika St. John’s Wort offers focused mood support, with potential benefits depending on the exact preparation. It can weaken oral contraceptives and other medicines, and interact with medicines that increase serotonin.

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

Nutrient Quality40

Hyperforin is identified, but a specific standardized extract is not established. That leaves the preparation’s quality and expected performance uncertain.

Ingredient Transparency100

The amount and a named component are disclosed. Those details make the label easier to compare, although they do not identify a complete standardized extract.

Value For Money40

The available information does not establish value for money. The named component alone does not resolve whether the cost is justified.

Customer Satisfaction73

Customer ratings are positive across several hundred reviews. They provide insight into satisfaction, without establishing mood benefits or medicine compatibility.

Product Focus54

The formula has a clear mood-support purpose, but potential benefits depend on the specific extract and the reason for low mood. Important medicine interactions also limit who it may suit.

B- Ingredient FitF PathwaysF EvidenceA+ Formulation Logic

St. John's wort may help with symptoms of mild to moderate depression, but that doesn't mean it improves everyday mood in healthy adults. The preparation matters, and the material here isn't identified as a specific standardized extract. It can also weaken oral contraceptives, anticoagulants and many other medicines, and interact with agents that increase serotonin.
