Protein, pre-workout and recovery with full-label transparency. Every tub lists its serving size, servings per pack and each ingredient with its amount, with no blends hiding the numbers.

Fuel Theory is the supplement brand at VoltFitness and makes almost all of that department: seven proteins, four pre-workout lines, four creatines, four recovery products and three boxes of bars, plus the shaker and funnel in Accessories. It sits in the mid tier, from $9 to $64.99.

Formulas are kept short and every ingredient is listed with its amount per serving. Flavours are few and named plainly, and claims stay modest: the products help with training, recovery and protein intake, and nothing more is promised. Expect plain tubs, clear labels and multi-buy prices on the everyday products.
