What is serotonin?

Serotonin is a neurotransmitter that helps elevate mood. The brain produces it when the body perceives sunlight. For people whose serotonin levels need to be regulated, a class of anti-depressants called SSRIs keep higher levels of serotonin in the bloodstream.

Serotonin is a hormone that is found naturally in the human brain; it is also found in the digestive tract and platelets of some animals, including human beings. It is also found in a variety of plant sources, including vegetables, fruits, and even mushrooms. Categorized as a neurotransmitter, it is important in transmitting nerve impulses. It is also described as a vasoconstrictor, which is a substance that can cause narrowing of the blood vessels. The amino acid tryptophan is credited with producing serotonin in the body.
