*Minimum recommended amount based on specified age and weight with no consideration for activity. For healthy adults aged 18–64, the recommended dietary allowance for protein is 0.8g protein/kg body weight per day (or 0.36g protein/lb body weight).¹ Experts recommend that adults aged 65 years and older consume more protein per day, approximately 1.1g protein/kg body weight (or 0.5g protein/lb body weight).² Physical activity, chronic illness, or injury may further increase protein needs. This protein calculator is intended for healthy adults and is not appropriate for children, pregnant or nursing women, competitive athletes, or people with specific diseases or medical conditions.
