Protein is one of the most important nutrients for maintaining a healthy and active lifestyle. It plays a major role in building muscles, improving physical performance, and supporting recovery after exercise. Whether you are an athlete, fitness enthusiast, or simply trying to stay healthy, consuming enough protein is essential for helping the body function efficiently and perform at its best. Protein is made up of amino acids, often called the building blocks of the body. These amino acids help repair tissues, support muscle development, and maintain important body functions. During physical activity or exercise, muscles go through stress and experience small tears. Protein helps repair these muscles, making them stronger over time. This is why protein is commonly associated with strength training, endurance workouts, and overall fitness improvement.
