Magnesium & Sleep: What the Science Actually Says

Magnesium reduces sleep friction via GABA/NMDA regulation, muscle relaxation, and stress buffering (Perlmutter, BioMed Central).

Benefits: Where Magnesium Helps Sleep

Faster Sleep Onset: Glycinate (200–350 mg, T-60–90) reduces latency after 7–14 nights (Perlmutter).
Fewer Wake-Ups: Supports stress buffering, neuromuscular calm for 2–3 a.m. stability.
Reduced Cramps/Twitches: Eases muscle contractions, especially for athletes.
Calmer Evenings: Less “wired-but-tired” with proper timing, environment (Sleep Foundation).

Side Effects & Safety: What to Watch in 2026

Common: GI upset, loose stools (oxide/citrate, high doses).

Rare: Hypotension, arrhythmia with overdose or kidney issues.

Interactions: Separate antibiotics/bisphosphonates (2–4 hrs), iron/calcium (~2 hrs) (NIH).

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

Forms Compared

Form	Why Used	Absorption	GI Tolerance	Bedtime Verdict
Glycinate	Calm, sleep	Strong	Gentle	Top choice
Citrate	Regularity	Good	Laxative-prone	Use earlier
Threonate	Cognitive	Lower elemental	Fine	Niche
Malate	Daytime energy	Good	Fine	Avoid late
Oxide	Budget	Poor	GI issues	Skip for sleep

Why Glycinate: High bioavailability, gentle, bedtime-friendly (ScienceDirect).

Dosing That Works

Start: 100–200 mg elemental magnesium glycinate.

Titrate: Increase by 50–100 mg after 7–10 nights, up to 200–350 mg.

Note: Check elemental Mg on label (NIH).

Best Time to Take Magnesium for Sleep

Sweet Spot: 60–90 min before bed (T-60–90).

Sensitive Stomach: T-90 with snack or split dose (100–150 mg dinner + 100–150 mg T-60).

Environment: Cool room (18–20 °C), low/amber light (Sleep Foundation).

Smart Stacks

L-Theanine (100–200 mg, T-60–90): Calms racing thoughts.

Glycine (1–3 g, T-60–90): Supports onset, continuity.

Melatonin (0.5–1 mg, T-30–60): For circadian shifts; start low.

Chamomile/Apigenin (tea or 50–150 mg, T-60): Gentle ritual.

Avoid: Iron/calcium/antibiotics at same time; separate appropriately (NIH).

Special Scenarios

Menopause: Glycinate T-60–90, glycine 1–3 g, cool room (18–20 °C).

Athletes: Glycinate for calm, daytime sodium/potassium-rich meals.

Shift Workers: Glycinate T-60–90 before sleep, melatonin 0.5–1 mg short-term.

Seniors: Start 100–150 mg, titrate carefully, check meds.

Sensitive Stomach: Glycinate, T-90 with snack or split dose; reduce if needed.
