This guide moves readers from explanation to step-by-step timing/dose to a clean product choice.

What Magnesium Does for Sleep (Fast Primer)

Magnesium supports sleep via nervous system calm (GABA/NMDA regulation), muscle relaxation, and stress buffering (PubMed). Low magnesium can increase cortisol and awakenings.

Best Time to Take Magnesium Glycinate for Sleep

60–90 Minute Rule: Take 60–90 min before bedtime for optimal absorption and nervous system calm (e.g., 9:00–9:30 p.m. for 10:30 p.m. bedtime).

Why Not at Lights-Out? Earlier dosing aligns calming effects with sleep pressure.

Sensitive Stomach/Reflux: Take at T-90 with a light snack (e.g., almonds, dark chocolate).

2–3 a.m. Wake-Ups: Keep T-60 to T-90 dose; add cool room, blackout curtains, no caffeine post-2 p.m.

How Much to Take (Elemental Mg) & How to Titrate

Start: 100–200 mg elemental magnesium glycinate 60–90 min before bed.

Titrate: After 7–10 nights, increase by 50–100 mg if needed, up to 200–350 mg.

Guardrails: Supplement UL ~350 mg/day (food not included); consult clinician for higher doses.

Patterns:

  • Single Dose: Simplest, at T-60 to T-90.
  • Split Dose: 100–150 mg with dinner + 100–150 mg at T-60 for sensitive stomachs.
  • Athletes: Bedtime dose + daytime sodium/potassium for cramps.

Pre-Bed Stacks: What Plays Nicely with Glycinate

Works Well:

  • Glycine (1–3 g): Enhances calm.
  • L-theanine (100–200 mg): Reduces mental chatter.
  • Low-dose melatonin (0.5–3 mg): Circadian nudge.
  • Lavender, breathwork, warm shower: Behavioral anchors.

Caution: Avoid high-dose melatonin (>3 mg); separate iron/calcium by ~2 hours.

Food, Caffeine, Alcohol & Meal Timing

Food: Take with or without food; sensitive stomachs use T-90 with a snack.

Caffeine: No caffeine after 2 p.m. to avoid sleep disruption.

Alcohol: Limit to modest amounts, not within 3 hours of bed.

Dinner: Finish 2–3 hours pre-bed; split dose if late meals.

Special Scenarios

Shift Workers: Dose 60–90 min before “bedtime”; use bright light day, blackout curtains night.

Athletes: Bedtime glycinate + daytime sodium/potassium; avoid laxative forms pre-workout.

Women’s Health: Nightly glycinate for luteal/perimenopause sleep; cool room for hot flashes.

Seniors: Start 100–150 mg, titrate to 200–300 mg; check med interactions.

Travel: Dose at new bedtime for 3–5 nights; use morning light, evening dimness.

Troubleshooting & Pro Tips

2–3 a.m. Wake-Ups: Keep dose, add no screens post-T-90, cool room, check caffeine/alcohol.

Stomach Upset: Use glycinate, split dose, or T-90 with snack.

No Change: Audit sleep window, light, caffeine; add L-theanine or increase dose within UL.

Leg Cramps: Check sodium/potassium, footwear, training load.

7-Day Timing Playbook

Assumes 10:30 p.m. bedtime; adjust to yours.

Day 1–2 (Reset):

  • 9:00 p.m.: 200 mg glycinate with snack.
  • 9:15 p.m.: Screens off, amber light.
  • 9:45 p.m.: Shower or 5–7 min breathwork.
  • 10:15 p.m.: Reading; lights out 10:30 p.m.

Day 3–4: Bump to 250–300 mg if onset >20 min.

Day 5–6: Add glycine (1–3 g) or L-theanine (100–200 mg) if needed.

Day 7: Check logs; hold dose if improved, adjust caffeine/meals if not.

Split-Dose Option: 100–150 mg dinner, 100–150 mg T-90.

Safety, Interactions & How to Stay Within Limits

UL: ~350 mg/day from supplements/medications (NIH); consult clinician for higher doses.

Interactions: Separate from antibiotics/bisphosphonates by 2–4 hours, iron/calcium by ~2 hours.

Side Effects: Loose stools indicate too much; reduce dose or split.

Medical Conditions: Consult clinician for kidney issues, pregnancy, or complex meds.

Why Magnesium Glycinate (Not Oxide/Citrate)

Glycinate: Chelated, gentle, glycine aids calm; ideal pre-bed.

Citrate: Good for regularity, take earlier.

Threonate: Cognitive focus, less elemental magnesium, pricier.
