Monster Energy Ultra Fiesta Mango Flavour Zero Sugar

About this product

This product carries a wellbeing score of 47%, which sits just below the neutral midpoint and suggests the formulation offers limited net benefit for overall wellbeing relative to a typical beverage. Its safety score of 88% is notably higher, indicating that the ingredient profile is generally well-tolerated for most consumers when used as intended.

Water serves as the primary base and hydration vehicle, while caffeine provides the central stimulant effect that supports alertness and energy. Taurine and L-carnitine L-tartrate are included to support metabolic and physical performance, and nicotinamide contributes B-vitamin activity that aids normal energy metabolism.

The main concerns centre on pyridoxine, which carries a high concern for peripheral neuropathy at elevated intakes, and nicotinamide, which has a medium concern for liver toxicity. Caffeine also presents a medium acute toxicity risk, particularly at high doses or for sensitive individuals, and L-carnitine L-tartrate may cause gastrointestinal upset at higher amounts.

Overall, this is a reasonably safe energy beverage for occasional consumption, though its moderate wellbeing score and a few ingredient-specific cautions suggest it is best enjoyed in moderation rather than as a daily staple.
