Valerian rootSupplement
Preliminary evidence
Within weeks

Valerian root

Sleep herb with EMA HMPC registration for sleep difficulty; modern trial evidence is mixed.

Read full evidence

Why

Valerian (Valeriana officinalis) has been used in Europe for sleep difficulty since at least the medieval era. The European Medicines Agency lists it as a registered Traditional Herbal Medicinal Product. Clinical trials show inconsistent results: some find subjective improvements, others find no effect, likely because valerenic acid content varies widely between extracts.

How it works

Valerenic acid binds GABA-A receptors and inhibits GABA breakdown; net effect is mild sedation similar to benzodiazepines but much weaker.

Expected onset · If no benefit by 2 weeks, unlikely to help further

How to take

Dosage

300–600 mg of standardized extract 30–60 minutes before bed.

Timing

Evening, 30–60 min before bed

On the label

Look for standardization to 0.8% valerenic acid.

Safety

Avoid combining with sedatives, alcohol, or benzodiazepines. Stop if drowsiness persists into the morning.

Evidence

At a glance

EMA HMPC lists Valeriana officinalis as a Traditional Herbal Medicinal Product for sleep difficulty (traditional-use registration, not full clinical authorisation). Modern RCT evidence is mixed, likely due to wide variation in valerenic acid content between extracts; choose products standardised to 0.8% valerenic acid.

PassionflowerSupplement
Moderate evidence
Within weeks

Passionflower

Gentle anxiolytic herb with EMA-monograph approval for nervous restlessness.

Read full evidence

Why

Gentle anxiolytic herb with EMA-monograph approval for nervous restlessness. Useful when the trouble falling asleep is rumination, not the bed.

How it works

Flavonoids (especially chrysin) bind benzodiazepine sites on GABA-A receptors, producing mild anxiolytic effects.

Expected onset · Often noticeable within 1–2 weeks for subjective sleep quality

How to take

Dosage

1–2 g of dried herb as an infusion 1–4 times daily, or equivalent dry extract; consult product label for standardised preparations.

Timing

Evening for sleep support; daytime doses for restlessness

Safety

Avoid combining with sedatives, alcohol, or benzodiazepines. Consult a doctor if symptoms persist beyond 2 weeks.

MelatoninSupplement
Moderate evidence
Acts fast

Melatonin

Endogenous hormone supplement; EFSA-authorised claim for reducing time to fall asleep at 1 mg taken close to bedtime.

Read full evidence

Why

Endogenous hormone supplement; EFSA-authorised claim for reducing time to fall asleep at 1 mg taken close to bedtime. Most useful for circadian shifts (jet lag, shift work).

How it works

Endogenous pineal hormone that binds MT1/MT2 receptors in the suprachiasmatic nucleus; shifts circadian phase and shortens sleep-onset latency.

Expected onset · Acute effect within 30–60 min; for circadian shifting allow several nights

How to take

Dosage

1 mg close to bedtime (EFSA-authorised dose for sleep-onset latency). For jet lag, 0.5–5 mg has been studied; higher doses are not more effective.

Timing

30–60 min before intended sleep time

Safety

May cause morning grogginess at higher doses. Avoid driving immediately after dosing. Discuss with a doctor if on antidepressants, anticoagulants, or immunosuppressants.
Check interactions with my medications

Evidence

At a glance

EFSA Scientific Opinion 2011 authorised the health claim that melatonin 1 mg taken close to bedtime contributes to a reduction in sleep-onset latency: a cause-and-effect relationship established from pooled human trial data. A separate 2010 EFSA opinion authorised the jet-lag claim. Higher doses are not more effective for sleep onset.

Sleep apnea screeningProgram
Strong evidence

Sleep apnea screening

Untreated obstructive sleep apnea drives cardiovascular and metabolic risk. Screen if you snore loudly, are tired despite enough hours, or have hypertension.

Read full evidence

Why

Obstructive sleep apnea (OSA) is common (~10-15% of adults), often undiagnosed, and causally linked to hypertension, cardiovascular events, cognitive decline, and all-cause mortality. STOP-BANG is the most validated screening questionnaire. Diagnosis is by polysomnography or home sleep apnea testing. CPAP and other treatments substantially reduce risk in moderate-severe OSA.

The program

  1. 1

    Take the STOP-BANG questionnaire (free online).

  2. 2

    If 3+ positives, ask your GP for a sleep study referral.

  3. 3

    Home sleep apnea testing or in-lab polysomnography confirms the diagnosis.

  4. 4

    If moderate-severe, options include CPAP, mandibular advancement device, weight loss, positional therapy.

  5. 5

    Re-screen if sleep quality degrades again after weight or lifestyle change.

Practical

Cadence

One-time screening; re-test if symptoms return

What you'll need

STOP-BANG questionnaire (online, 8 yes/no questions)

Ideal for

Loud snorers, witnessed apneas, daytime fatigue despite adequate sleep duration, hypertension, large neck circumference, BMI ≥35.

Markers this may influence

Evidence

At a glance

AASM 2017 clinical practice guideline (Kapur et al., J Clin Sleep Med) recommends polysomnography or home sleep apnea testing for symptomatic adults; Wisconsin Sleep Cohort (Peppard 2013) estimates moderate-to-severe OSA prevalence at 10–17% of middle-aged adults and finds most cases undiagnosed.

Weighted blanketCautionProgram
Moderate evidence
Within weeks

Weighted blanket

Deep-pressure stimulation. RCT: nearly 26× more likely to halve insomnia severity vs. control blanket.

Read full evidence

Why

Weighted blankets, typically dosed around 10% of body weight (the dosing rule used in the Ekholm 2020 RCT below), deliver continuous deep-pressure stimulation, hypothesised to increase parasympathetic tone and reduce arousal. Ekholm 2020 J Clin Sleep Med RCT (n=120) in patients with insomnia plus a psychiatric disorder showed 60% achieved 50%+ Insomnia Severity Index reduction with the weighted blanket vs. 5% with the light control blanket.

The program

  1. 1

    Pick a weight ~10% of your body weight (often 6-8kg for adults).

  2. 2

    Use as the primary blanket. Allow 1-2 weeks to adapt to the weight.

  3. 3

    Pair with the rest of your sleep hygiene: cool room, dim evening light.

  4. 4

    If sleep doesn't improve in 4 weeks, reassess; it isn't for everyone.

Practical

Cadence

Use as your primary blanket through the night

What you'll need

Choose ~10% of body weight; not for OSA, claustrophobia, or young children

Ideal for

People with anxiety-driven insomnia or stress-related sleep difficulty.

Caution: Avoid in obstructive sleep apnea, claustrophobia, respiratory or circulatory problems, and for young children (suffocation risk).

Evidence

At a glance

Ekholm 2020 J Clin Sleep Med RCT (n=120, insomnia plus psychiatric disorder): a ~10%-body-weight chain blanket vs light control over 4 weeks. 60% of the weighted-blanket group vs 5% of controls achieved ≥50% reduction in Insomnia Severity Index (Cohen's d 1.90, p<0.001).

CBT-i (cognitive behavioural therapy for insomnia)Program
Strong evidence
Within weeks

CBT-i (cognitive behavioural therapy for insomnia)

First-line treatment for chronic insomnia per the AASM. More effective than sleeping pills long-term.

Read full evidence

Why

CBT-i combines stimulus control, sleep restriction, and cognitive restructuring across 4-8 sessions. The American Academy of Sleep Medicine 2021 clinical practice guideline rates it a STRONG recommendation for chronic insomnia disorder in adults, stronger than any pharmacological treatment.

The program

  1. 1

    Start a daily sleep diary: bedtime, wake time, awakenings.

  2. 2

    Calculate your average sleep efficiency (sleep / time-in-bed × 100%).

  3. 3

    Sleep restriction: shrink your time-in-bed to match average sleep, then grow as efficiency rises.

  4. 4

    Stimulus control: bed = sleep only. Out of bed if not asleep within ~20 minutes.

  5. 5

    Cognitive restructuring: address sleep-effort and catastrophising thoughts.

  6. 6

    Maintenance phase: continue diary, expect occasional regressions.

Practical

Cadence

4-8 weekly sessions plus daily sleep diary

What you'll need

Insomnia ≥3 months. Find a CBT-i provider (BSM-trained psychologist) or digital programme (Sleepio, Somryst).

Ideal for

Anyone with insomnia lasting more than three months.

Markers this may influence

Evidence

At a glance

Trauer 2015 Ann Intern Med meta-analysis (20 RCTs, n=1,162): CBT-i shortened sleep-onset latency by ~19 min, reduced wake-after-sleep-onset by ~26 min, and raised sleep efficiency by ~10 percentage points, with gains sustained at follow-up. AASM 2021 gives it a STRONG recommendation, stronger than any drug.

What we'd skip

CBD oil and standalone apigenin: heavy marketing, thin human evidence. Prescription sleeping pills work, but dependence and rebound insomnia are why CBT-i leads our non-supplement list instead.

FAQ

Frequently asked

Practical answers to the questions readers most often arrive with.

  • Which natural sleep aid has the strongest evidence?
    Valerian root has the longest regulatory record: the EMA HMPC monograph covers traditional use for restlessness and sleep. Melatonin at 0.3–1 mg taken close to bedtime carries an EFSA-authorised claim for reducing sleep latency. For chronic insomnia, Cochrane's review finds CBT for insomnia (CBT-I) more durable than any drug or herb. Most herbal aids work best as adjuncts to good sleep hygiene.
  • How long does it take valerian to work?
    Valerian's effect on sleep latency is modest and typically takes 2–4 weeks of consistent nightly use to plateau. It is not a sleeping pill; readers expecting a benzodiazepine-like switch will be disappointed. It works best as part of a wind-down ritual rather than a single-night fix.
  • Is melatonin safe for long-term use?
    Available data suggests melatonin at low doses (0.3–3 mg) is well tolerated for at least 12 months in adults. The bigger issue is dose: most commercial products contain 5–10 mg, which is 10–30× higher than physiological levels and may suppress endogenous production. EFSA's authorised claim is at 1 mg, taken 30 minutes before bedtime.
  • What is the best magnesium form for sleep?
    Magnesium glycinate or bisglycinate. The glycine carrier itself has mild calming activity, and the form is gentler on the gut than magnesium oxide or citrate. 200–400 mg elemental magnesium in the evening is the typical range; effect is cumulative over days to weeks.
  • Can I take valerian with antidepressants?
    Discuss with your prescriber. Valerian has additive sedative effects with benzodiazepines and possibly with sedating antidepressants (trazodone, mirtazapine). Most SSRIs don't have a direct interaction signal, but the combination has not been formally studied. Check the free interaction reference for your specific drug.
  • Does tart cherry juice actually help sleep?
    Small RCTs (Howatson 2012, Losso 2018) report modest improvements in total sleep time and sleep efficiency with 30 ml Montmorency cherry concentrate twice daily for 1–2 weeks. The mechanism is naturally-occurring melatonin in the fruit. Effect is smaller than CBT-i but larger than placebo: a food-based entry point worth a 2-week trial.
  • Hops on its own, does it work?
    EMA HMPC monograph registers Humulus lupulus as a Traditional Herbal Medicinal Product for mild stress and sleep. The clearer modern RCT signal is for valerian-hops fixed combinations (e.g. Ze 91019), not hops alone. Hops also contains 8-prenylnaringenin, a potent phytoestrogen: avoid in hormone-sensitive conditions.
  • Is glycine just for collagen, or does it really help sleep?
    Both. Yamadera 2007 and Bannai 2012 small RCTs found that 3 g of glycine pre-bed improved subjective sleep quality and reduced daytime sleepiness in partially sleep-restricted adults. The mechanism involves mild peripheral vasodilation that drops core body temperature: the documented sleep-onset signal. Distinct from glycine's role as a collagen-synthesis substrate.
  • Is 5-HTP a good sleep aid?
    Small RCT signal for both sleep onset and mild mood support. The Cochrane review of 5-HTP and tryptophan for depression found a directionally positive but methodologically-limited signal. Real interaction profile: risk of serotonin syndrome with SSRIs, SNRIs, MAOIs, triptans and St John's wort. Not casual.
