Analysis

The 1000 mg serving provides flowering-top extract without active-marker standardization in a focused alcohol-free liquid format. No unrelated active ingredients dilute the intended mood-support role.

No hypericin or hyperforin standardization is given, so different batches may not deliver identical active strength. The large herb weight does not by itself establish clinical potency.

Adults who prefer a alcohol-free liquid and take no interacting medicines may value the format. Accurate measurement matters, and a standardized extract would provide more predictable dosing.

Who is it for
  • Adults seeking focused St. John’s wort support
  • People who take no interacting medicines
  • Users who prefer a alcohol-free liquid
Best for
  • Focused mood-support supplementation
  • Whole-herb St. John’s wort use
  • measured liquid serving daily use

Pros

  • Focused single-herb formula
  • Clearly states a 1000 mg serving
  • measured liquid serving format

Cons

  • Hypericin and hyperforin are not standardized
  • Extensive medication interactions restrict use
  • Liquid measurement affects dose accuracy

Warnings

  • St. John’s wort can sharply reduce the effectiveness of oral contraceptives, warfarin, transplant medicines, HIV medicines, and many other drugs by speeding their clearance.
  • Combining St. John’s wort with SSRIs, SNRIs, MAO inhibitors, triptans, tramadol, or dextromethorphan can cause dangerous serotonin excess.
  • St. John’s wort can increase sensitivity to sunlight, so strong sun or UV exposure may require extra skin and eye protection.

Nutrient quality

84 Highest impact

A named plant-part extract and substantial daily amount support focused use. Missing active-marker standardization limits consistency and potency confidence.

.

Ingredient transparency

79 High impact

The extract amount and plant part are clearly disclosed without a hidden blend. Active-marker strength, complete directions, and inactive ingredients are not supplied.

.

Customer satisfaction

69 High impact

The supplied average rating is strong. A very large rating base makes the average dependable, but no detailed experience evidence was supplied.
