Summary

Monster Energy Zero Ultra scores 37/100. Zero sugar, and the functional ingredients are legitimate — taurine, L-carnitine and a B-vitamin complex behind 150mg of caffeine. The additive system is the weak point: two artificial sweeteners (sucralose + acesulfame potassium), a sorbic acid and benzoic acid preservative pair, artificial flavors, and ester gum. The B12 is cheap cyanocobalamin rather than bioactive methylcobalamin. Dropping the sugar is what separates it from the original Monster by more than 30 points.
