Alanine and carnosine are important chemicals found in muscle that affect strength and metabolism. Alanine is an amino acid that provides energy during exercise and prevents tired muscles by increasing tissue carnosine levels. Carnosine is a combination of two amino acids found in meat that is composed of the amino acids alanine and histidine. It is incorporated into many tissues, including skeletal muscles and smooth muscles in the arteries. Carnosine is also an important antioxidant that protects cells from destruction and fights acids that cause fatigue. It is critical for muscle building and may help prevent nerve degeneration and diabetes. A study from Belgium found that -alanine (4.8 grams per day for four weeks) increased muscle carnosine levels by 16 percent, prevented fatigue during repeated bouts of high-intensity knee extensions, but had no effect on isometric endurance or 400-meter sprint times. -alanine promotes performance in intensely trained athletes.
