Protein Calculator

The RDA is 0.8g per kg of body weight for general health. Active individuals need 1.2-1.6g/kg, and those building muscle need 1.6-2.2g/kg.

For healthy adults, protein up to 2.2g/kg is well-studied and safe. Higher amounts may be safe but have less research support. Those with kidney disease should consult a doctor.

Complete protein sources include chicken breast (31g/100g), eggs (6g each), fish (20-25g/100g), Greek yogurt (17g/170g), and tofu (8g/100g).
