The core product line uses shakes and bars with controlled calories, protein, fiber, and vitamins to replace one or two meals per day. This structure helps people manage calorie intake without extensive meal prep.
Formulation Standards
Each product undergoes testing for macronutrient stability, taste, and texture to ensure consistency across flavors and formats. Fortification with micronutrients supports daily nutritional needs when used as directed within a balanced diet.
