Amino acids are derived from protein and they are the main building blocks in the body. For example, they are used to make hormones, neurotransmitters and enzymes. Some of them are essential, meaning they need to be taken in from the diet, whilst the others can be manufactured in the body.
As you hopefully can see from the above, amino acids are pretty important. But some of them can become problematic for people with bladder pain. These are tyrosine, tryptophan, tyramine and phenylalanine (called the ‘arylalkylamines’).
