HelloPharmacist Scorecard of Chasteberry 150 mg by NaturesPlus Herbal Actives

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

None of the active ingredients could be matched to our evidence database, so intended use can't be graded.

Why this rating?
  • None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Ingredient Transparency
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • “Chasteberry” is listed as a grouped ingredient — the label gives one combined amount (150 mg) without saying how much of each component you get.
Known Interaction Concern
Not assessable

None of the active ingredients could be matched to our interaction database.

Why this rating?
  • We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
Safety Information
Unable to assess

None of the active ingredients could be matched to our safety data.

Why this rating?
  • We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.

HelloPharmacist summaryFully disclosed formula with no assessable stated purpose. Medication interactions could not be assessed, and safety information could not be assessed.

Assessment coverage: 0 of 2 active ingredients matched to our full ingredient reviews (monographs). Based on the product label dated Oct 24, 2023.

This Scorecard evaluates available label information, ingredient evidence, and known medication-safety considerations. It does not independently verify product identity, purity, potency, contamination, or manufacturing quality. How these ratings are computed
