Protein is one of the building blocks of bone, muscle, and skin. The body needs it to produce hormones, enzymes, and other chemicals.
The possible health benefits of protein powders include the following:
Weight management
A 2017 review reported that supplementing with whey protein might reduce body weight and total fat mass in people who are overweight or obese.It may also reduce blood pressure, total cholesterol, and other risk factors for cardiovascular diseases.

Muscle growth
Protein is essential for muscle growth. Many athletes and gym enthusiasts consume protein shakes because they believe that these drinks will help them bulk up after strength training.
A 2018 analysis of 49 studies supports the use of protein supplementation for this purpose. The research suggests that protein supplements significantly improve muscle size and strength in healthy adults who perform resistance exercise training, such as lifting weights.
Protein supplementation was equally effective in men and women. However, the effectiveness may decrease with age, as older adults have higher protein requirements than younger people.
The researchers also noted that once protein exceeded 1.6 grams (g) per kilogram (kg) of body weight (or 0.73 g per pound (lb) of body weight), the participants did not experience any additional benefits.
Recovery after exercise
As well as contributing to muscle growth, protein can help repair damaged muscles and tissues. As a result, athletes may use protein powder to speed up recovery from muscle soreness after exercise.
That taking protein supplements after exercise can aid recovery by reducing muscle damage and improving muscle performance and muscle protein synthesis.
