According to current research, what is the optimal range of daily protein intake to maximize muscle protein synthesis?

The optimal range for daily protein intake to maximize muscle protein synthesis is generally established within the range of 1.6 to 2.2 grams per kilogram of body weight. This range has been supported by current research, which suggests that higher protein intakes can significantly enhance the process of muscle recovery and growth, particularly in individuals engaged in resistance training and other forms of strenuous physical activity.

At the lower end of this range, 1.6 grams/kilogram is often sufficient for most individuals looking to increase muscle mass or maintain lean muscle during caloric restriction. On the higher end, approaching 2.2 grams/kilogram may be beneficial for those with higher training volumes or specific goals related to muscle hypertrophy. It is important to note that individual factors such as age, sex, level of physical activity, and overall caloric intake can influence protein needs, but the consensus in the literature supports this range for maximizing muscle protein synthesis effectively.
