There is no indication on Herbsmith’s own specification for their canine supplement as to whether their product is standardized in this way, but given the scale upon which these supplements are sold, this would be a reasonable assumption to make. However, if the product is standardized to a different percentage than 80%, then this obviously has an implication for carrying out a cost comparison and an effectiveness review of the Herbsmith product alongside competing Milk Thistle products for dogs.

Review of Milk Thistle Extract for Psoriasis Relief - Nootriment
A comprehensive review by the U.S. Agency for Healthcare Research and Quality (AHRQ) recently identified 16 scientific studies on the use of milk thistle for the treatment of various forms of liver disease. A European standardized extract of milk thistle was used in most of the trials. Problems in study design (such as small numbers of participants, variations in the causes of liver disease, and differences in dosing and duration of milk thistle therapy) made it difficult to draw any definitive conclusions. However, five of seven studies evaluating milk thistle for alcoholic liver disease found significant improvements in liver function. Those with the mildest form of the disease appeared to improve the most. Milk thistle was less effective for those with severe liver disease such as cirrhosis. Cirrhosis is characterized by scarring and permanent, non-reversible damage to the liver. It is often referred to as end-stage liver disease.While this all sounds promising, studies in people have been flawed, and results have been inconsistent or inconclusive. In a 2007 review of 13 clinical trials, the independent Cochrane Collaboration questioned the use of milk thistle for alcoholic liver disease and hepatitis B and C because of the poor quality of the research.
