Glutamine: A Conditionally Essential Amino Acid. Glutamine is a non-essential amino acid under normal conditions, meaning the body is able to produce enough to meet its own requirements. Glutamine becomes essential during certain physiological states, which is why it is termed a 'conditionally essential' amino acid 2.
Essential Amino Acids. The essential amino acids, which are also referred to as indispensable, are the ones you must get through the foods you eat because your body canât make them. Nine out of the 20 amino acids are essential, but adults only need to obtain eight of them: valine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine and tryptophan. The ninth amino acid -- histidine -- is only essential for infants. Your body doesnât store amino acids, so it needs a regular daily supply of these essential building blocks.
