Leucine
Leu, L
Leucine is an essential amino acid that is important for protein synthesis in the body. It is one of the three branched-chain amino acids (BCAAs) along with isoleucine and valine. Leucine is abundant in animal products such as meat, dairy, and eggs, as well as plant sources such as soybeans, nuts, and legumes.
Leucine plays a critical role in muscle protein synthesis, which is the process of building new muscle tissue. It activates an enzyme called mammalian target of rapamycin (mTOR), which stimulates muscle protein synthesis. This is why leucine is known as an anabolic amino acid and is often included in muscle-building supplements.
Apart from muscle building, leucine has other important roles in the body. It is involved in energy production, glucose regulation, and immune function. Leucine also helps in the healing and recovery of muscles after intense exercise.
It is recommended that adults consume about 2-3 grams of leucine per meal to promote muscle protein synthesis. However, athletes or people trying to build muscle may require higher amounts. It is always advisable to consult with a healthcare professional before taking any supplement containing leucine.
