All living cells contain a protein. Protein - a substance necessary for life. Protein is vital for your body to maintain lean body mass. The higher the percentage of muscle in relation to fat mass, the more calories you burn during the day! You lose weight when your body gets sufficient protein. I liked the product, a powder without taste, with a slightly vanilla aroma. The Bank and the amount of powder is simply huge, enough for a long time. I am adding to beverages, omelettes, curd to increase the amount of protein.
