Anchor wake time
A consistent wake time helps stabilize the sleep-wake rhythm.
Functional Medicine Guide 03
Sleep, light and circadian health
Build a repeatable rhythm and know when a sleep concern needs professional assessment.
Rhythm before rescue
Sleep is shaped by timing, light, behavior, health conditions and environment.
A functional assessment looks beyond hours in bed: schedule regularity, morning and evening light, caffeine and alcohol, movement, stress, pain, breathing, medications and the bedroom environment can all matter. Snoring, witnessed breathing pauses, severe daytime sleepiness and persistent insomnia warrant clinical evaluation.
Use light deliberately
Seek daytime light and reduce bright light close to bedtime when possible.
Build a downshift
Create a repeatable transition with lower stimulation, a calm environment and fewer late stimulants.
Escalate red flags
Do not use supplements to mask possible sleep apnea, mood disorders or medication effects.

GABA + Magnesium Glycinate
This evening-routine formula includes GABA, L-theanine, magnesium, ashwagandha and vitamin C. Evidence for oral GABA is limited and mixed; L-theanine research is more promising but varies by dose. It is not an insomnia or anxiety treatment.
Review the evidence and safety notes →Medication and drowsiness check
Discuss sedatives, alcohol, pregnancy, thyroid or liver conditions and persistent sleep symptoms with a qualified clinician.
