Is Liv 52 better than milk thistle?

The use of Liv 52 for liver regeneration is only due to its long-term use and there is no scientific evidence of its effectiveness, but studies are available showing the hepatoprotective (protective properties of milk thistle).

Liv 52 is a traditional herbal medicine with a complex composition (contains, m.in, chicory seeds, yarrow and tamarisk herb), which is used as an adjunct after liver damage and during its regeneration: https://www.gdziepolek.pl/produkty/44664/liv-52-tabletki/apteki

I can't find a product called Ostrosep - maybe you meant Milk Thistle? It is a plant whose fruits have a protective effect on the liver. The main ingredient responsible for the medicinal properties of milk thistle fruit is a complex of flavonolignanic compounds with a strong antioxidant effect - silymarin.
