For menopause sleep specifically, the right supplement depends on what’s actually disrupting your sleep. Here’s the ranking by evidence and by how reliably each addresses a specific driver.

#1: Magnesium glycinate

The consensus starting point. 200–400mg elemental magnesium glycinate 30–60 minutes before bed.

What it targets: Sleep onset and anxiety-driven restlessness.

Limits: Doesn’t directly address hot flashes or severe cortisol-driven 3am wakeups. A minority of users experience paradoxical sleep disruption.

#2: Oral micronized progesterone (prescription)

Not a supplement but worth mentioning here because it’s the most effective sleep aid in the perimenopause toolkit for many women. 100–200mg at bedtime, within an HRT regimen, directly targets the progesterone-depletion contribution to sleep loss. Prescription only.

#3: Melatonin

Modest evidence for menopause sleep specifically. Most useful for sleep onset rather than sleep maintenance. Low dose (0.5–3mg) often works better than high dose (5–10mg) — paradoxically.

What it targets: Delayed sleep onset, particularly if you’re keeping irregular hours.

Limits: Won’t stop 3am wakeups driven by cortisol or vasomotor symptoms. Can produce next-day grogginess at higher doses.

#4: L-theanine

An amino acid from green tea. Calming without sedation. 100–400mg before bed. Pairs well with magnesium for women whose issue is more “can’t wind down” than “hormonal disruption.”

What it targets: Racing-mind-at-bedtime sleep onset difficulty.

#5: Ashwagandha

For women whose sleep pattern is cortisol-driven (wake up wired, morning anxiety, waking around 2–4am feeling alert). KSM-66 300–600mg, often taken evening. Evidence is moderate.

#6: Glycine

3g at bedtime has modest evidence for sleep quality improvement. Well-tolerated. Often stacked with magnesium glycinate (which also supplies glycine).

Honest mentions (limited evidence)

Valerian. Mixed evidence, paradoxical stimulation for some. Skip unless nothing else is helping.

CBD. Widely used in community; trial evidence for menopause sleep is preliminary. Quality varies dramatically by product.

Tryptophan / 5-HTP. Modest evidence; interactions with SSRIs are significant — don’t combine without a prescriber.

Skip

  • “Sleep blend” proprietary formulas with undisclosed dosing
  • Over-the-counter antihistamines (Benadryl, etc.) as sleep aids — cognitive fog, anticholinergic burden, tolerance develops fast
  • Kava — liver safety signal
  • Anything positioned as a “menopause cure” that happens to also be for sleep

Matching supplement to pattern

💡 A decision guide
  • Trouble falling asleep, generally anxious → magnesium glycinate + L-theanine
  • Wake at 3am wired → magnesium glycinate + ashwagandha + address cortisol/glucose
  • Wake drenched from night sweats → address vasomotor cause (HRT conversation); supplements are secondary
  • Irregular sleep schedule, delayed sleep onset → magnesium + low-dose melatonin
  • Severe chronic insomnia → supplements alone aren’t enough; CBT-I + potential medication

What no supplement does

No supplement on the market addresses severe menopause sleep disruption driven by untreated vasomotor symptoms as effectively as treating the vasomotor symptoms themselves. If you’re drenching nightly, supplements are a complement — not a substitute — for the HRT or fezolinetant/gabapentin conversation.
