THE SLEEP COLLECTION
SLEEP 101
Sleep happens in 90-minute cycles: light sleep, deep sleep (physical repair), and REM (mental processing). Each cycle requires the nervous system to downshift — GABA increases, cortisol drops, melatonin rises. Nutrient deficiencies in this downshift machinery mean you lie awake, tired but wired.
Magnesium supports GABA (the brain's "off switch"). L-theanine (from green tea) promotes alpha brain waves — calm alertness that transitions to sleep. Glycine lowers core body temperature, a biological sleep signal. Melatonin is the hormone that tells your brain it's dark. Each works on a different mechanism.
Melatonin helps with timing — falling asleep — but not with sleep quality or depth. High doses can cause grogginess and vivid dreams. Most practitioners recommend magnesium and L-theanine as the foundation (they improve sleep architecture) and reserve low-dose melatonin for jet lag or shift work.
