Coming in two innovative Mars Protein Bar variations: Raspberry Smash and Salted Caramel but now with vastly reduced sugar levels, these new Mars Hi-Protein Low Sugar Bars offer an improved macronutrient profile compared to the original Mars Protein Bars.

Think of them as Mars Protein V2.0, each bar now packs in 18-grams of milk-based protein and has under 2-grams of sugar from 17-grams of carbs in total. The fruity notes in the raspberry version and super salty caramel in the other still deliver on flavour even with the reduced sugar levels.
