Shift Worker / Night Owl
About this protocol
Where to start
Melatonin timing matters more than dose. Take 0.3-0.5 mg 30-60 min before your sleep window, regardless of clock time. This signals "night" to your brain.
Add magnesium glycinate before sleep — same as conventional sleep protocols.
L-theanine for the wind-down phase.
Ashwagandha for the chronic cortisol dysregulation shift work imposes — 600 mg with the "morning" meal (whenever that is for you).
Use blackout curtains, eye mask, and white-noise machine during daytime sleep. Light leakage is the biggest practical obstacle.
4 nutrients
Start here
Strongest evidence — the foundation of the stack.
Melatonin (Low-Dose, Timed)
0.3-0.5 mg, 30-60 minutes before your sleep windowTimed low-dose melatonin signals circadian alignment when sleeping outside normal hours. Higher doses (3-10 mg) are LESS effective for phase-shifting and cause next-day grogginess.[1, 2]
Magnesium Glycinate
300-400 mg elemental, before sleepNervous system relaxation for sleep onset and maintenance regardless of clock time.[3, 4]
Add if needed
Add these only if the foundation isn't enough.
L-Theanine
200 mg, 30-60 minutes before your sleep windowWind-down support for atypical sleep hours.[5, 6]
Ashwagandha (KSM-66)
600 mg with breakfast (whenever that is)Shift work elevates chronic cortisol. Ashwagandha modulates HPA-axis activity over 8 weeks.[7, 8]
Warnings
Lifestyle improvements
Light is the strongest circadian signal
Use bright light at your "morning" (work start) and avoid bright light approaching your sleep window. Light therapy glasses or a 10,000-lux lamp can help.
Blackout your sleep environment
Daylight sleep requires real blackout — full curtains, eye mask, white-noise machine.
Consistent schedule (within the shift)
Even on days off, try to maintain similar sleep timing. Bouncing between shift schedule and "normal" weekends is the hardest pattern on circadian health.
Limit caffeine to the first half of your shift
Same half-life rules apply regardless of clock time.

Better Sleep
sleep
Magnesium, glycine, L-theanine, and apigenin work through complementary mechanisms (GABA modulation, NMDA antagonism, core body temperature regulation) to support faster sleep onset and deeper sleep. Evidence ranges from moderate (magnesium, glycine) to emerging (apigenin). This is a foundational sleep stack — not a substitute for sleep hygiene basics.
Falling Asleep Faster
sleep
Sleep-onset insomnia (difficulty falling asleep) is mechanistically distinct from sleep-maintenance issues (waking up). The drivers are usually nervous system over-activation, melatonin signaling, and core body temperature — not deep sleep architecture. This stack targets sleep onset specifically: magnesium for GABA modulation, L-theanine for alpha-wave relaxation, low-dose melatonin as a circadian signal (NOT a sedative), and glycine for the core body temperature drop that precedes sleep. Use this for "I can''t turn my brain off at night" patterns. If you fall asleep fine but wake up at 3 AM, see Staying Asleep instead.
Staying Asleep (Wake-Ups)
sleep
Mid-night waking (especially the 2-4 AM "wide awake" pattern) is usually driven by elevated cortisol, fragmented deep sleep, or blood-sugar dips. This stack targets sleep MAINTENANCE rather than onset — phosphatidylserine and ashwagandha to blunt evening cortisol, magnesium and glycine for deeper, less fragmented sleep architecture, and L-theanine to help you fall back asleep if you do wake. Use this for "I fall asleep fine but wake at 3 AM and can''t go back" patterns. For sleep-onset issues, see Falling Asleep Faster.
Deep Sleep & Recovery
sleep
Slow-wave (deep) sleep is when growth hormone peaks, memory consolidates, and tissue recovery accelerates. Some people sleep 8 hours but get insufficient deep sleep — often visible in poor next-day recovery, brain fog, and slow gains from training. This stack targets deep sleep architecture specifically: apigenin and magnesium L-threonate (crosses blood-brain barrier better than other forms), glycine for slow-wave enhancement, L-theanine for alpha-wave priming, and zinc for testosterone-mediated sleep architecture support.
Daily Calm
stress· 3 shared ingredients
Chronic everyday stress is a different beast than acute panic — what you want is HPA-axis modulation over weeks, not sedation. Ashwagandha (KSM-66) is the headline ingredient: trial evidence shows lower cortisol and lower perceived stress after 8 weeks of daily use. L-theanine is a fast-acting "calm but alert" add-on for individual stressful moments (presentations, conflicts, mid-afternoon overwhelm). Magnesium glycinate supports nervous system relaxation and downstream sleep quality, which compounds — better sleep → lower next-day stress reactivity.
Anxiety Relief
stress· 3 shared ingredients
Anxiety is different from stress. Stress is a response to external demand; anxiety is the persistent anticipation of threat — often without a clear external trigger. This distinction matters because the supplement levers differ. For acute anxiety (a presentation, a flight, a difficult conversation), fast-acting non-sedating options like L-theanine work. For chronic, lower-grade everyday anxiety, magnesium and ashwagandha modulate the HPA axis over weeks. For panic attacks, severe anxiety disorder, or anxiety that disrupts daily function, please see a mental health professional — supplements are first-line for mild-to-moderate symptoms only.
