Key facts
Seller-stated formulationThis gives you a defined daily amount and stated marker standardization to check against the package label.

Choose it if you want an adult St. John’s Wort capsule with the stated 900 mg daily amount and 0.3% hypericin standardization. Keep the effectiveness claim appropriately open.
Buy on AmazonWhen the label matters
You are comparing mood-support supplements and pause over a bottle labeled for adults, capsules, and a defined daily amount.
A defined formulation
This herbal supplement uses a capsule format with a seller-stated 900 mg daily amount and extract standardized to 0.3% hypericin. That standardization names a marker level intended to keep servings consistent, while the advertised mood and tranquility benefits remain seller claims—not proof it will work for every person.
The useful choice is formulation clarity, not a guarantee about your individual mood.
