Each Beef Amino tablet contains a total of 19 essential and non-essential amino acids. Amino acids are the building blocks of proteins and muscle tissue. Protein contributes to the growth and maintenance of muscle mass and the maintenance of normal bones. Due to the beef protein amino acids, Beef Amino tablets contain a high dose of natural BCAAs and glutamine. As these ingredients have a low fat and carbohydrate content, Beef Amino is an excellent choice even when you are building lean muscles. Beef Amino is lactose free, and is therefore an ideal nutritional supplement for those who are sensitive to lactose, too. Like all BioTech USA products, Beef Amino consists of safe and carefully selected ingredients.
