Your "happiness neurotransmitter" — produced during daylight hours and converts to melatonin in the evening. About 90% is produced in your gut, highlighting the crucial connection between digestive health and sleep quality.
Your body's natural sleep hormone, produced when darkness falls. Peaks during the night and declines toward morning as cortisol rises.
Your brain's primary "brake pedal" — the main calming neurotransmitter that quiets mental chatter and promotes relaxation. Low GABA is associated with insomnia, anxiety, and restless sleep.
