According to the NIH, teenage boys aged 14–18 need an average of 52 grams of protein per day, while girls of the same age need around 46 grams, providing a clear starting point for understanding what is the RDA for protein for adolescents. This essential macronutrient fuels the rapid development that occurs during the adolescent years, supporting everything from muscle growth to a robust immune system.

Active teenage boys typically require 2,800 to 3,200 calories per day just to maintain their weight, while active teen girls need 2,200 to 2,400 calories. To effectively build muscle, a 14-year-old must consume even more than this baseline to create the necessary caloric surplus.

Athletic teenagers have significantly higher protein and carbohydrate needs than their less active peers, especially during periods of rapid growth and intense training. Understanding **how much protein does a 15 year old need to build muscle** is crucial for fueling recovery, optimizing growth, and maximizing athletic performance safely and effectively.
