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

Nutrient Quality23

The milk-thistle compounds are named, but detailed forms for glutathione and alpha lipoic acid are not disclosed. That leaves the quality and absorption of the complete formula uncertain.

Ingredient Transparency75

All ingredient amounts are listed, making quantities straightforward to compare. Most detailed forms are not disclosed, limiting comparison of the ingredient versions.

Value For Money62

Glutathione and milk thistle offer favorable value at the serving cost. Value for alpha lipoic acid remains uncertain without a reliable comparison.

Customer Satisfaction90

Customer ratings are very positive across a very large number of reviews. They give broad satisfaction feedback without confirming an effect on inflammation.

Product Focus53

Glutathione may change the body’s antioxidant balance, which differs from reducing inflammation or its symptoms. Everyday inflammatory benefits remain uncertain, and the small alpha lipoic acid amount does not establish added support.
