Beef is low in fat, but rich in conjugated linoleic acid. These potential antioxidants can effectively resist tissue damage caused by weightlifting and other sports. In addition, linoleic acid can also be used as an antioxidant to maintain muscle mass. Zinc is another antioxidant, which helps to synthesize protein and promote muscle growth. Zinc strengthens the immune system together with glutamate and vitamin B6***. Magnesium supports the synthesis of protein, enhances muscle strength and, more importantly, improves the efficiency of insulin anabolism.
