5-HT (5-hydroxytryptamine)

5-HT, or serotonin, is a chemical messenger in your body that plays a key role in regulating mood, sleep, appetite, and digestion. It’s produced mainly in the brain and gut, and helps transmit signals between nerve cells. Adequate levels of serotonin are associated with feelings of well-being and stability, while imbalances can influence conditions like depression or anxiety. Many medications, such as antidepressants, work by adjusting serotonin levels to improve mood and emotional health. Overall, serotonin is essential for maintaining various physical and mental functions that contribute to your overall balance and health.
