Analysis

The two-capsule serving provides 700 mg of St. John’s wort extract. Its focused design delivers a large extract weight without unrelated ingredients.

No hypericin, hyperforin, plant-part, or extraction-ratio detail is supplied. The amount is plausible for mood support, but extract weight alone does not guarantee consistent active potency.

A 90-serving bottle offers strong value despite the two-capsule requirement. Users who want marker certainty should favor a standardized extract rather than choosing by milligrams alone.

Who is it for
  • Adults seeking a high-weight St. John’s wort extract
  • Value-focused users who have screened medication interactions
Best for
  • Economical substantial-dose St. John’s wort
  • A simple two-capsule extract serving

Pros

  • Provides 700 mg of extract
  • Focused single-active formula
  • Ninety servings
  • Very favorable serving value

Cons

  • No hypericin standardization
  • No hyperforin detail
  • Plant part is not identified
  • Requires two capsules

Warnings

  • Do not combine St. John’s wort with SSRI, SNRI, MAOI, or other serotonergic medicines because serotonin toxicity can occur.
  • St. John’s wort can reduce the effectiveness of oral contraceptives, warfarin, transplant medicines, some HIV medicines, and several seizure medicines.
  • The herb can increase sensitivity to sunlight, so extra sun protection may be needed.
  • People with bipolar disorder should avoid unsupervised use because St. John’s wort can trigger agitation or mania.

Nutrient quality

83 Highest impact

A substantial extract amount directly fits mood support, but absent active-marker standardization limits potency confidence. The focused formula avoids filler and remains within a plausible daily range.

Ingredient transparency

77 High impact

The shown active amounts are generally clear, with no proprietary blend obscuring the main doses. Daily directions and a complete inactive-ingredient list are not supplied.

Customer satisfaction

59 Moderate impact

The supplied aggregate rating is favorable and supported by a limited review volume. Detailed feedback is unavailable, so repeated complaints and fit with the intended use cannot be judged.

Value for money

94 Highest impact

The formula provides strong practical value for its quality and serving profile. Few low-value additions dilute the core formula.

St. John’s wort is a directly mood-focused botanical with strong human evidence for mild to moderate depressive symptoms. The extract amount is clinically plausible, but missing hypericin or hyperforin standardization limits potency confidence.

The single-herb design provides focused depth without unrelated ingredients. St. John’s wort can reduce the effect of oral contraceptives and anticoagulants, and combining it with serotonergic antidepressants can cause a serious interaction.
