L-Isoleucine is one of the nine essential amino acids that is not produced in the body. It can be obtained from animal sources like liver, fish, eggs, chicken, meat and vegetable sources like rye, cashew nuts, almonds, lentils, chickpeas and soy proteins. The metabolism of L-Isoleucine takes place in muscle tissue. It is needed for the formation of hemoglobin and stabilizes and regulates blood sugar and energy levels. It is also known to increase endurance levels and helps in the recovery of muscles after exercise. It strengthens the immune system’s ability to fight off infections and increases the level of growth hormones and insulin to maintain the body’s balance. A deficiency leads to a number of physical and mental disorders with symptoms similar to hypoglycemia.

L-Leucine with the food additive E number code E641 is classified as a flavor enhancer. Leucine is actually an essential alpha-amino acid and a vital part of so called “buffer” proteins, such as ferritin and astacin. You can find leucine in foods such as whole wheat bread products, nuts and brown rice. As a supplement, researchers have found that leucine slows the degradation of muscles and muscle tissues through an inflated synthesis of muscle proteins. In the human body, leucine can be found in the liver, but most prominently in the muscle and adipose tissues, where it is utilized in production of sterols. In body building circles L-Leucine as a dietary supplement is very popular for all these properties, but also for the preservation of muscle glycogen, nitrogen balance maintenance and more.

L-Valine is an amino acid with stimulant activities. It not only helps in tissue repair but also promotes muscle growth. It is one of the three branched amino acids that are formulated for providing support to the human body for normal functioning. Derived from animal and vegetable protein, L-Valine is not only involved in the synthesis of protein and metabolism of glucose but it also regulates the immune system. L-Valine is also effective in maintaining the exercise recovery time and the balance of nitrogen in the body. Since the human body doesn’t produce this amino acid naturally, you need to acquire it through dietary supplements and food items. When taking L-Valine supplements, you must follow strict directions from the physician. Even though it doesn’t have any side effects, it helps to consult the physician before its usage.
