An independent Supplement Wise review of Herbsmith Herbsmith Milk Thistle, built only from facts published on the manufacturer's official product page. Anything the manufacturer does not publish is shown as not published and earns no credit.
A strongly formulated and documented supplement with only limited gaps.
Confidence is calculated separately from the product score, from how complete our source record is.
One ingredient-first score out of 100, always the exact sum of six categories: scientific value of the ingredients 40, formula and effective dosing 25, ingredient quality and safety 15, manufacturing quality 10, usage and practicality 5, and country of origin 5. Where our research record is still open we say so and lower confidence — we never treat a gap in our own research as evidence against a product, and reviews never affect the score.
No published safety review is on file for this supplement. That is an absence of information, not evidence that the product is safe. Always check with your veterinarian before adding a supplement, especially alongside medication.
Canadian retailers on record. Stock and price vary by store and province.
Actives and their disclosed amounts, exactly as published on the label. Undisclosed amounts earn no scoring credit.
