The essential amino acids contained in Wolf's EAAs cannot be produced by the body itself. Therefore, they must be added through food. We use very high-quality, fermented, essential amino acids that are very effective and efficient. You save calories compared to conventional protein powders and do not fill your stomach, making them easy to digest. They are free from additives and sweeteners, which are often present in protein shakes like strawberry flavor, for example. The capsule form allows you to take the protein anytime and anywhere without carrying a shaker or other items. It is the simple form of protein intake and, as the name suggests, ESSENTIAL for humans.
