Staying Asleep (Wake-Ups)
About this protocol
Where to start
Start with phosphatidylserine in the evening (200-300 mg). The most-evidenced supplement for blunting elevated evening cortisol, the most common cause of 2-4 AM wake-ups.
Add ashwagandha (KSM-66) with breakfast for daily cortisol modulation. Effect builds over 8 weeks.
Add magnesium glycinate before bed for deeper sleep architecture and fewer micro-arousals.
Add glycine for the body-temperature-related fragmentation pattern.
If wake-ups are accompanied by sweating, anxiety, or 3 AM dread — that''s the cortisol signature, prioritize phosphatidylserine + ashwagandha.
4 nutrients
Start here
Strongest evidence — the foundation of the stack.
Phosphatidylserine
200-300 mg, 1-2 hours before bedPhosphatidylserine blunts evening cortisol elevation — the most common driver of 2-4 AM wake-ups. Trial evidence in adults with chronically elevated evening cortisol supports improved sleep continuity and morning energy.[1, 2]
Ashwagandha (KSM-66)
600 mg, with breakfastAshwagandha lowers HPA-axis activation and serum cortisol. Trial evidence supports improved sleep quality and reduced anxiety over 8 weeks. Particularly useful for stress-related sleep fragmentation.[3, 4, 5]
Add if needed
Add these only if the foundation isn't enough.
Magnesium Glycinate
300-400 mg elemental, before bedMagnesium reduces micro-arousals and supports deeper sleep architecture. Foundational for any sleep-maintenance stack.[6, 7]
Experimental
Emerging evidence — try last, only if curious.
Glycine
3 g, 30-60 minutes before bedGlycine improves slow-wave sleep quality and reduces fragmentation. Particularly useful if you wake feeling overheated.[8, 9, 10]
Warnings
Lifestyle improvements
Address evening cortisol behaviorally
Bright screens, doom-scrolling, late workouts, and emotional content in the evening elevate cortisol. A hard cutoff 1-2 hours before bed transforms wake-up patterns within a week.
Eat enough protein at dinner
Blood-sugar dips in the early morning can trigger wake-ups in some people. A protein-containing dinner stabilizes overnight glucose.
Limit alcohol
Alcohol fragments deep sleep in the second half of the night — the exact window when 2-4 AM wake-ups occur.
Address chronic stress
Phosphatidylserine and ashwagandha are downstream of stress. Address the upstream causes directly.
See a sleep specialist if persistent
Persistent maintenance insomnia warrants evaluation for sleep apnea, restless legs, or other primary sleep disorders.
