Serotonin Question: What is Serotonin?
Serotonin is a neurotransmitter used at the ends of nerves. It is manufactured in your body using the amino acid tryptophan. At the meeting of one nerve with another there is a space. Release of serotonin (or other drugs-depending on the type of nerve) causes the other nerve to fire and continue the message along the “cable”. Its other name is 5- hydroxytryptamine and is also found in platelets. Release of serotonin by injured platelets is thought to cause blood vessels to contract.
