Expert opinion

“Although we are aware of the importance of vitamins B and gut function, we often forget about our liver, which does a huge job every day by processing everything that passes through the small intestine. It is, therefore, worth supporting. In the BestNAC formula, I have included N-acetylcysteine (NAC), which has at least 25 proven health benefits, as well as glucoraphanin and sulforaphane.“
