Capture the essence.

• L-Leucine, L-Isoleucine and L-Valine are the three members that make up a VIP amino acid club called branched-chain amino acids (BCAAs). Now, why are they so relevant? The importance of BCAAs lies in the way the body metabolizes them and the biological processes they trigger.

• L-Histidine plays a key role as a protein component. It's also important as a precursor of histamine. Initially thought essential only for infants, longer-term studies have shown it's essential for adults too.

• L-Lysine is an essential amino acid that can only be obtained by means of food and is used as a building block for many important functions.

• L-Threonine is an essential amino acid and a precursor to the amino acids glycine and serine. It's found in eggs, milk, gelatine, and other proteins.

• L-Phenylalanine, an essential amino acid also provided by food, plays an important role in the biosynthesis of other amino acids and in the structure and function of many proteins and enzymes.

• L-Methionine is a sulfur-containing essential amino acid that is crucial in many key functions. It's found in meat, fish, and dairy products.

• L-Tryptophan is naturally found in animal and plant proteins. It's an essential amino acid that the body needs in order to synthesize proteins.
