Amino acids are the building blocks of protein and they perform a variety of roles in the body. Some amino acids are used to make hormones, enzymes, and other important molecules, while others are used as a source of energy or to help repair tissue. There are 20 different amino acids that can be found in proteins, and they are divided into two groups: essential and nonessential amino acids. Essential amino acids cannot be made by the body and must be obtained from food.
Nonessential amino acids can be made by the body and do not need to be obtained from diet. L-Theanine and L-Tyrosine are two examples of amino acids that have specific roles in the body. L-Theanine is an amino acid that is found naturally in tea leaves and it has been shown to promote relaxation without causing drowsiness. L-Tyrosine is an amino acid that plays a role in the production of neurotransmitters like dopamine and norepinephrine. It has been shown to improve cognitive function during stress.
