Hormonal
Older adults require higher total protein intakes (1.0–1.5 g/kg/d) and higher EAA/leucine density to overcome anabolic resistance and maximize muscle protein synthesis.
If you are over 65, aim for 1.0 to 1.5 grams of protein per kilogram of body weight daily. Focus on protein sources rich in essential amino acids, especially leucine, to help your muscles respond better to food and exercise. This helps prevent age-related muscle loss.

Expert groups recommend intakes of 1.0–1.5 g/kg/d for older adults (≥65 y) to minimize age-related declines in health and function.
Why this rating
The paper cites expert group recommendations and multiple studies on MPS in older adults, providing robust evidence for this specific demographic.
