Summary

Monster Energy Zero Ultra scores 37/100. The functional ingredients are legitimate — taurine, L-carnitine, and a B-vitamin complex provide genuine energy support alongside 150mg caffeine. However, the additive profile is heavily processed: sucralose and acesulfame potassium (double artificial sweeteners), sorbic acid and benzoic acid (dual chemical preservatives — the benzoic acid + citric acid combination raises benzene formation concerns), artificial flavors, and ester gum. The B12 is the cheap cyanocobalamin form rather than bioactive methylcobalamin. Zero sugar but far from clean.
