DHM is not a probiotic
Dihydromyricetin is a chemical compound found in plants. A probiotic is a live microorganism. ZBiotics identifies its Pre-Alcohol organism as Bacillus subtilis ZB183. Comparing the products by DHM milligrams would therefore be inappropriate: a chemical amount and a strain-based formulation are different measures.
