AI assessment of the formula, label and price. How scoring works

Nutrient Quality23

The glutathione and alpha lipoic acid forms are unspecified, so their quality is difficult to compare. Milk thistle is described more clearly, but its form information does not establish the quality of the whole formula.

Ingredient Transparency60

All ingredient amounts are disclosed. Some forms and the proportions of the milk thistle components remain unspecified.

Value For Money82

Glutathione and milk thistle look favorable for value at the serving cost. There is not enough price information to judge the alpha lipoic acid contribution confidently.

Customer Satisfaction89

Buyer ratings are positive across a large number of reviews. That supports a positive picture of satisfaction, while reviews do not establish health benefits.

Product Focus53

The short ingredient list keeps the formula focused on antioxidant-related support. Alpha lipoic acid is present at a lower amount than the relevant inflammation evidence described.
