St. John's Wort Extract
Swanson Superior Herbs' "St. John's Wort Extract" is a botanical supplement providing 300 mg of standardized St. John's Wort extract per capsule. St. John's Wort is commonly used for its potential to support mood and emotional well-being. The product's single active ingredient ensures clear label transparency regarding the extract dosage. Research suggests that effective dosages of St. John's Wort extract typically range from 300 mg to 900 mg daily, often standardized to hypericin or hyperforin content. While the 300 mg dosage is within the lower end of this range, the lack of specific standardization information makes it difficult to fully assess its potential efficacy. The product earned an N+ Score of 45, an 'F' grade, and is in the below-average tier, partly due to this ambiguity and the potential for a higher dose to be more effective.
