Nutrient quality

75 High impact

The extract lacks specific standardization for silymarin, which may result in inconsistent levels of active flavonoids. While safe and appropriately dosed for maintenance, it does not feature advanced bioavailability enhancements.

Ingredient transparency

91 Highest impact

Labeling is clear regarding the quantity of the extract, but the absence of a silymarin percentage limits transparency regarding potency. Serving instructions and other ingredients are plainly disclosed for consumer ease.

Customer satisfaction

93 Highest impact

High review volume and a strong average rating reflect consistent satisfaction among users. Feedback appears well aligned with the intended goal of supporting liver health and detoxification.

Value for money

94 Highest impact

This is one of the most affordable liver support options available on a cost-per-serving basis. While the extract quality is basic, the low price makes it highly accessible for foundational supplementation.
