1. Beef is rich in sarcosine: the content of sarcosine in beef is higher than any other food, which makes it particularly effective for muscle growth and strength enhancement. In the first few seconds of training, sarcosine is the source of muscle fuel, which can supplement adenosine triphosphate and make the training last longer.

2. Beef contains vitamin B6: The greater the demand for protein, the more vitamin B6 should be added to the diet. Beef contains enough vitamin B6, which can help you enhance your immunity and promote the metabolism and synthesis of protein, thus helping your body recover after intense training.

3. Beef contains carnitine: the content of carnitine and sarcosine in chicken and fish is very low, and the content of beef is very high. Carnitine is mainly used to support fat metabolism and produce branched-chain amino acids, which plays an important role in muscle growth of bodybuilders.

4. Beef contains potassium and protein: Potassium is a mineral that most athletes lack in their diet. The level of potassium will inhibit the synthesis of protein and the production of growth hormone, thus affecting muscle growth. Beef is rich in protein.

5. Beef is a low-fat source of linoleic acid: the fat content in beef is very low, but it is 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 muscles.

6. Beef contains zinc and magnesium: Zinc is another antioxidant, which contributes to the synthesis of protein and promotes muscle growth. Zinc strengthens the immune system together with glutamate and vitamin B6. Zinc supports the synthesis of protein, enhances muscle strength and, more importantly, improves the efficiency of insulin anabolism.

7. Beef contains iron: Iron is an essential mineral for hematopoiesis. In contrast to the low iron content in chicken, fish and turkey, beef is rich in iron.

8. Beef contains alanine: The function of alanine is to produce sugar from protein in the diet. If you don't eat enough carbohydrates, alanine can supply the energy needed by muscles to alleviate the deficiency, so that you can continue training. The biggest advantage of this amino acid is that it can free muscles from the burden of supplying energy.

9. Beef contains vitamin B 12: Vitamin B 12 is very important for cell production, and the function of red blood cells is to bring oxygen to muscle tissue. Vitamin B 12 can promote the metabolism of branched-chain amino acids, thus providing energy for high-intensity training.
