bodybuilding amino acids supplements - AMINO ACID 1000 MG COMPLEX - l-arginine l-citrulline amino acid complex - 2 Bottles 200 Capsules MUSCLE BUILDING SUPPLEMENTS: The primary reason that people turn to amino acid supplements, though, has to do with muscle growth. Leucine, in particular, has been shown to regulate and improve muscle protein synthesis after exercise. Stimulated by the stress of your workout and encouraged by the jolt of leucine, then, your muscles will have everything they need to grow and be better prepared for your next workout. FAT LOSS WORKOUT: Research has closely linked amino acid supplementation not only with fat loss but a reduction in abdominal fat deposition and storage. Abdominal fat forms around vital organs and other parts of the body, increasing inflammation and reducing function, so the fact that amino acid supplements can reduce this specific type of fat is very important for health. EXERCISE SUPPLEMENTS: Amino acids assist in muscle building and help reverse muscle breakdown, which can aid in building muscle mass. Exercise science research suggests that these tendencies may also assist in enhancing exercise performance in endurance sports. A 2009 study, published in the "Journal of Nutrition Science and Vitaminology" found athletic performance was higher when using a amino acid supplement compared to a placebo. ENERGY BOOSTING SUPPLEMENTS: During states of increased amino acid levels, the amino acids will compete with glucose to provide energy, thereby becoming a secondary source of energy. In one study, people with high levels of amino acids required 36% less glucose.
