The Raab Bio Protein Shake is purely vegetable and is based on a combination of pea and rice protein. The mixture is completed by the local superfood spinach. The shake contains 78% vegetable protein, of which 34% are essential amino acids. 2.7 g BCAAs², of which 1.2 g leucine, are contained per serving. Proteins contribute to an increase in muscle mass and the maintenance of muscle mass. The body cannot synthesize essential amino acids itself, which is why they have to be taken in through food. The shake has a reserved taste and can be used universally.
