Product analysis

45 out of 100

St. Johns Wort 1000 mg is aimed at mood support, but benefits are uncertain because its preparation is not clearly identified. It can weaken contraceptive pills, blood thinners and many other medicines, making compatibility with existing medicines a key concern.

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

Nutrient Quality20

The St. John’s wort preparation is unspecified. The declared weight alone does not show whether it matches an identified extract.

Ingredient Transparency63

The ingredient amount is listed. Its preparation is omitted, making comparison with specific extracts difficult.

Value For Money40

There is not enough cost information to establish value for money. The unspecified preparation also limits a direct comparison with identified extracts.

Customer Satisfaction74

Customer ratings are positive across several hundred reviews. That gives a useful picture of satisfaction without establishing mood benefits.

Product Focus47

The single herb keeps the formula focused on mood-related use. Benefits from particular extracts do not establish a reliable everyday mood lift from this unspecified preparation.

St. John's wort benefits concern particular extracts used for diagnosed depression, so a routine mood lift in healthy adults is uncertain. The declared material here isn't identified as one of those standardized preparations, and its 1,000 mg amount doesn't make it equivalent. It can also weaken oral contraceptives, anticoagulants and many other medicines, a practical concern that the amount alone cannot answer.

How this product is rated for Mood Support

Ingredient fit97

The declared ingredients provide a concrete connection to mood, with benefits depending on the conditions described above.
Goal fit
St. John's Wort is the sole identified ingredient relevant to this mood explanation.
Dose adequacy
St. John's Wort 1000 mg. These are serving amounts, not necessarily daily amounts.

Pathways16

Mood-related ingredient roles are identified, but mechanisms alone do not tell you how your mood will change.
Depth
The ingredients relate most directly to calming; a calming role alone does not guarantee a change in mood.
Breadth
These ingredient roles do not show that every aspect of emotional well-being will improve.

Evidence27

St. John's wort benefits concern particular extracts used for diagnosed depression, so a routine mood lift in healthy adults is uncertain.
Evidence strength
St.
Studied preparation
The declared preparation does not fully match the specific material associated with the relevant mood benefit.

Formulation logic100

No particular ingredient conflict or missing required companion is identified. Known amounts do not by themselves guarantee a mood benefit.
Partner coverage
No required companion ingredient is missing for the identified ingredients.
Conflicts
No particular conflict between the declared ingredients is identified.
Effective doses
The individual amounts are available; this does not make the serving a recommended dose for mood.
