Many athletes and physically active people seek to increase their muscle mass and sports performance. To accomplish this, nutrient intake should be increased. In order for the body to grow in terms of size it needs to take more energy than it consumes, i.e. more calories. These calories should be derived from quality protein, complex carbohydrates and healthy fatty acids and the prerequisite for achieving desired results is that these ingredients are easily digested, i.e. they can be absorbed by your body without unwanted eliminations.
