About protein intake

Protein is essential for muscle repair, hormone production, and overall metabolic health. The RDA of 0.8 g/kg is the minimum to prevent deficiency, not the optimum. Active individuals and those building muscle typically need 1.6-2.2 g/kg. Older adults benefit from the higher end of this range to preserve lean mass. This calculator combines your weight, activity, and goals to estimate where you fit within the evidence-based range.
