Nutricost St John’s Wort Capsules (500mg) — 120 Vegetarian Capsules

Nutricost offers a straightforward 500 mg capsule with 120 vegetarian capsules per bottle. The product lists 500 mg of St. John’s Wort per capsule and identifies the only active ingredient as St. John’s Wort itself. Best for budget-conscious buyers seeking a pure, single-ingredient supplement without extra fillers. A potential limitation is the lack of additional standardized hypericin data on the label, which some users look for in potency comparisons.
NusaPure St. John’s Wort Capsules, 500 mg

NusaPure provides 500 mg per capsule with 200 capsules per bottle, offering a long supply. The product emphasizes non-GMO and vegan status, with USA-made manufacturing per its description. It suits buyers who want a high-capsule-count option and prefer vegan certificates. A consideration is the absence of explicit hypericin standardization data on the listing, which may matter to users comparing extract potency.
Nature’s Way St. John’s Wort Capsules

Nature’s Way packages St. John’s Wort at 700 mg per 2-capsule serving, with 180 capsules per bottle. The product emphasizes non-GMO and vegan status, with a standardized extract approach. This option may appeal to buyers seeking a higher per-serving dose while maintaining vegan and non-GMO attributes. A drawback is the 2-capsule serving size, which may not suit those who prefer single-capsule daily dosing.
Zazzee Extra Strength St. John’s Wort 20:1 Extract

Zazzee offers a potent 20:1 extract with 0.3% hypericin in a 150-capsule bottle. The high-potency extract is designed for users seeking robust support, with a five-month supply at typical dosing. Best for those who want a concentrated extract rather than plain powder. A potential limitation is higher potency requiring attention to dosage to avoid over-supplementation. Label highlights emphasize strong hypericin content as a differentiator.
St John’s Wort Capsules by Healths Harmony

Healths Harmony provides a high-potency offering with 900 mcg of Hypericin per serving in a simple, one-capsule-per-serving format. The bottle contains 120 capsules and is manufactured in a GMP-certified US facility with globally sourced ingredients. This option suits buyers seeking a precise hypericin-focused dosing in a straightforward capsule. A caution is that some users may be sensitive to higher hypericin levels, so start with the recommended serving.
Buying Guide: Key Considerations For St. John’s Wort 500 mg
- Potency and extract form: Decide between a plain 500 mg extract or a concentrated 20:1 extract. Higher hypericin content can influence mood support intensity but may require careful dosing.
- Capsule vs tablet: If you prefer easy swallowing or vegan/vegetarian options, pick capsules; tablets may be more convenient for those who dislike capsules.
- Certifications: Look for non-GMO, vegan, and gluten-free labeling. USA manufacturing and GMP certification can indicate consistent quality controls.
- Serving size practicality: Some products use one capsule per serving, others require two. Consider your daily routine and planned dosing to avoid confusion.
- Allergy and ingredient clarity: Choose products that list only active ingredients or clearly disclosed blends to minimize allergen exposure.
