Amino acids are the building blocks for proteins. Their roles in the body are as diverse as the parts of the body. People take amino acids to help with weight control (there are some that act to curb the appetite), to help in outbreaks of coldsores, and as a way to supply their body with amino acids that their diet might be lacking. If you are on any medication or have any pre-existing health condition, you will want to check with your healthcare provider for advice regarding the use and dosage of individual amino acids (particularly if you are on any type of MAO inhibitor.)
