Serotonin is a neurotransmitter that plays a vital role in many bodily functions, including mood, sleep, and appetite. It is often referred to as the "feel-good" neurotransmitter because it is associated with feelings of happiness, well-being, and contentment. However, serotonin also plays a role in other important functions, such as regulating body temperature, heart rate, and muscle contractions.
Serotonin is produced in the brain and gut. The majority of the body's serotonin is produced in the gut, where it helps to regulate digestion and intestinal motility. The brain also produces serotonin, which is involved in a variety of cognitive and emotional processes. When serotonin levels are high, people tend to feel happier, more relaxed, and more focused. When serotonin levels are low, people may experience symptoms such as depression, anxiety, and fatigue.
In the following sections, we will discuss the role of serotonin in various bodily functions, the factors that can affect serotonin levels, and the symptoms of serotonin deficiency.

Serotonin is often referred to as the "feel-good" neurotransmitter because it plays a vital role in regulating mood. When serotonin levels are high, people tend to feel happier, more relaxed, and more optimistic. When serotonin levels are low, people may experience symptoms of depression, anxiety, and irritability.
Serotonin is involved in several mood-related processes, including:
- Emotional processing: Serotonin helps to regulate the way we process emotions. It can help to reduce feelings of sadness, anger, and fear, and promote feelings of happiness, contentment, and well-being.
- Stress response: Serotonin is involved in the body's response to stress. It can help to reduce the release of stress hormones, such as cortisol, and promote a sense of calm and relaxation.
