Ranked for Better Sleep

Category
  1. Magnesium

    8.5–9.0 /10 for better sleep 8.5–9.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Mah 2021 anchors the most relevant signal. Magnesium fits sleep quality when low intake, stress load, mineral loss, or a form-specific target makes deficiency correction plausible. The score stays bounded because effects…

  2. Taurine

    8.5–9.0 /10 for better sleep 8.0–8.5/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Jia 2008 reports Mechanistic receptor paper supporting GABA-A activity relevant to sleep and calmness claims. The score stays conditional because Taurine still needs better outcome data for this exact use case. The…

  3. Glycine

    8.5–9.0 /10 for better sleep 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Bannai 2012 anchors the most relevant signal. Glycine fits sleep quality because glycine participates in sleep signaling, glutathione, collagen, methylation, and nervous-system balance, depending on the endpoint. The score stays bounded because…

  4. Tirzepatide

    8.0–8.5 /10 for better sleep 6.0–6.5/10 overall Worth trying Metabolic & Incretin Peptide

    The evidence base includes nine trials covering 7,111 adults, showing that Tirzepatide produces clinically meaningful weight loss and improves cardiometabolic risk factors Franco 2025. Tirzepatide's impact on sleep-quality is inferred from its…

  5. Infrared Sauna

    7.5–8.0 /10 for better sleep 7.0–7.5/10 overall Strong recommend Sauna & Heat Therapy

    Oosterveld 2009 gives the most relevant evidence anchor. The existing rationale points to this narrower claim: Evening sauna 2-3 hours before bed can speed sleep onset through post-heat core-temperature decline and relaxation.…

  6. Neurofeedback

    7.0–7.5 /10 for better sleep 8.0–8.5/10 overall Strong recommend Neurostimulation & Neurofeedback

    Arns et al. 2009 gives the strongest anchor. Sleep claims need tempering. SMR protocols and clinical reports support insomnia work, but Recio-Rodriguez 2024 found no clearly favorable pooled effect for PSQI and…

  7. Melatonin

    7.0–7.5 /10 for better sleep 7.5–8.0/10 overall Strong recommend Exogenous Metabolite

    Melatonin has a modest but repeatable sleep-quality effect, especially when the problem is timing rather than heavy sedation need. The PLoS One meta-analysis of 19 RCTs found sleep-onset latency improved by 7.06…

  8. Saffron

    7.0–7.5 /10 for better sleep 7.0–7.5/10 overall Strong recommend Botanical Extract (non-adaptogenic)

    Schuster et al. 2025 is the best anchor here because it reports decentralized randomized trial, 165 randomized adults and 20 mg or 30 mg saffron improved Athens Insomnia Scale at 4 weeks…

  9. Earthing

    7.0–7.5 /10 for better sleep 6.5–7.0/10 overall Worth trying Grounding & Earthing

    Earthing interventions for sleep-quality have also been described in an early pilot that measured cortisol and subjective sleep improvements in twelve participants, but that study lacked a control group and remains low-certainty…

  10. Red Light Therapy

    6.5–7.0 /10 for better sleep 7.5–8.0/10 overall Strong recommend Light Therapy

    Red Light Therapy may support sleep indirectly through pain reduction, circadian timing, and lower inflammation, while Ji 2024 did not find a significant sleep outcome. That mixed result keeps the score below…

  11. Zone 2 Cardio

    6.5–7.0 /10 for better sleep 8.0–8.5/10 overall Strong recommend Cardiovascular

    Kodama 2009 gives the most relevant evidence anchor. The existing rationale points to this narrower claim: Regular moderate aerobic exercise tends to improve sleep onset, sleep continuity, and perceived sleep quality over…

  12. L-Theanine

    6.5–7.0 /10 for better sleep 7.5–8.0/10 overall Strong recommend Amino Acid

    Lyon 2011 supports objective sleep-quality improvements in boys with ADHD. Bulman 2025 and Cotter 2026 strengthen subjective sleep-quality and latency evidence, while objective adult sleep endpoints remain less convincing. That makes L-Theanine…

  13. PEMF (Pulsed Electromagnetic Field Therapy)

    6.5–7.0 /10 for better sleep 7.5–8.0/10 overall Strong recommend PEMF

    Pre-bed PEMF mat protocols often subjectively support relaxation and sleep onset, but controlled sleep evidence is much thinner than pain and orthopedic evidence. The most defensible claim is wind-down support, not direct…

  14. Vagus Nerve Stimulation

    6.5–7.0 /10 for better sleep 7.0–7.5/10 overall Strong recommend Neurostimulation & Neurofeedback

    Pre-bed protocols are supported by autonomic logic and a small Zhang 2024 insomnia RCT showing a clinically meaningful PSQI advantage over sham at 8 weeks. The score stays bounded because Vagus Nerve…

  15. Ashwagandha

    6.5–7.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Adaptogenic Herb

    The evidence points to a plausible use case without proving a universal response. Fatima et al. 2024 is the best anchor here because it reports five randomized trials, 254 participants and reduced…

  16. Epitalon

    6.5–7.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Mitochondrial & Longevity Peptide

    The evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor here because it reports independent in vitro study and normal epithelial…

  17. HRV Biofeedback

    6.0–6.5 /10 for better sleep 9.0–9.5/10 overall Top-tier Wearable & Tracker

    Shao 2024 supports selective use. Pilot RCTs show improved subjective sleep quality with pre-sleep practice. Mechanism via parasympathetic upregulation before bed. The score stays bounded because HRV Biofeedback evidence for sleep quality…

  18. Semaglutide

    6.0–6.5 /10 for better sleep 6.0–6.5/10 overall Worth trying Metabolic & Incretin Peptide

    Kosiborod 2024 showed symptom improvement in obesity-related HFpEF with type 2 diabetes, and weight loss can reduce sleep-apnea load. This is an indirect sleep use case. Semaglutide may help when excess weight,…

  19. Molecular Hydrogen

    5.5–6.0 /10 for better sleep 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Dhillon 2024 reports 25-article systematic review; mixed preliminary clinical evidence, heterogeneity, and need for stronger trials. Zhou 2024 points in the same direction, but route, dose, baseline status, and outcome tracking decide…

  20. Time-Restricted Eating

    5.5–6.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Fasting Protocol

    Chen X et al. 2026 is the best anchor here because it reports 41 randomized trials, 2,287 participants and early TRE outperformed late TRE for body weight and fasting insulin and the…

  21. Traditional Sauna (Finnish Dry-Heat)

    5.5–6.0 /10 for better sleep 7.5–8.0/10 overall Strong recommend Sauna & Heat Therapy

    The mechanism is well grounded in sleep physiology: a sauna raises core and skin temperature, and the subsequent drop as the body cools mimics the natural pre-sleep temperature decline that signals sleep…

  22. Collagen Peptides

    5.5–6.0 /10 for better sleep 7.0–7.5/10 overall Strong recommend Amino Acid

    Bannai 2012 found 3 g glycine before bed improved subjective sleep quality. About 12 g collagen can deliver a similar glycine dose. That makes Collagen Peptides more defensible when sleep quality is…

  23. Rapamycin

    5.5–6.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Longevity & mTOR Drug

    Harrison 2009 anchors the most relevant signal. Rapamycin fits sleep quality when mTORC1 modulation, autophagy, immune aging, or senescence biology is the actual target. The score stays bounded because human longevity endpoints…

  24. Methylene Blue

    5.5–6.0 /10 for better sleep 6.0–6.5/10 overall Worth trying Mitochondrial & Redox Drug

    Ramsay 2007 is the cleanest verified anchor for this report. The existing rationale points to this narrower claim: Sleep effects are mostly indirect and can cut both directions. Some users sleep better…

  25. Apigenin

    5.5–6.0 /10 for better sleep 5.5–6.0/10 overall Worth trying Botanical Extract (non-adaptogenic)

    Adib-Hajbaghery 2017 found chamomile extract improved sleep quality in older adults, while pure Apigenin still lacks a sleep RCT. The mechanism is plausible: Apigenin interacts with GABA-A signaling, which can lower arousal…

  26. Kava (Piper methysticum)

    5.5–6.0 /10 for better sleep 5.5–6.0/10 overall Neutral Botanical Extract (non-adaptogenic)

    The benefit is real but mostly indirect: by lowering bedtime anxiety and rumination it can shorten sleep onset, and its sedating cultivars promote relaxation in the evening. Dedicated polysomnography evidence is thin,…

  27. Adaptogenic Mushrooms (Reishi, Cordyceps, Chaga)

    5.5–6.0 /10 for better sleep 5.0–5.5/10 overall Neutral Functional Mushroom

    Reishi is the classic evening mushroom, and the human signal is indirect but real. In Tang 2005, neurasthenia patients on reishi polysaccharide reported better well-being and less fatigue, outcomes that overlap with…

  28. Norwegian 4×4

    5.0–5.5 /10 for better sleep 8.0–8.5/10 overall Strong recommend Cardiovascular

    A 2024 umbrella review found that high-intensity interval training performed in the late evening may delay sleep onset in sleep-sensitive individuals Poon 2024. Morning or early-afternoon sessions tend to avoid the sympathetic…

  29. Essential Amino Acids

    5.0–5.5 /10 for better sleep 7.5–8.0/10 overall Strong recommend Amino Acid

    Hagiyama 2024 reports 12 RCTs; 622 patients; low-certainty improvement in patient-reported outcomes and very-low-certainty strength signal after lower-limb surgeries. Wittholz 2024 points in the same direction, but route, dose, baseline status, and…

  30. Vitamin D3 + K2

    5.0–5.5 /10 for better sleep 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Jolliffe 2021 anchors the most relevant signal. Vitamin D3 + K2 fits sleep quality when deficiency, bone risk, immune seasonality, or fat-soluble nutrient gaps are present. The score stays bounded because benefits…

  31. Phosphatidylserine

    5.0–5.5 /10 for better sleep 7.0–7.5/10 overall Strong recommend Vitamin & Mineral & Nutrient

    The rationale is cortisol-timing dependent: lower evening HPA-axis overactivation may help some stressed users sleep, while late dosing can also cause insomnia. No dedicated sleep-quality RCT exists. The score stays bounded because…

  32. Ketogenic Diet

    5.0–5.5 /10 for better sleep 6.5–7.0/10 overall Worth trying Diet & Nutrition Protocol

    The evidence points to a plausible use case without proving a universal response. Leung GKW et al. 2025 is the best anchor here because it reports 33 randomized trials and 2821 individuals…

  33. Ca-AKG (Calcium Alpha-Ketoglutarate)

    5.0–5.5 /10 for better sleep 6.5–7.0/10 overall Worth trying Vitamin & Mineral & Nutrient

    Shahmirzadi 2020 is the cleanest verified anchor for this report. The existing rationale points to this narrower claim: No direct Ca-AKG sleep trial or consistent community signal. Keep neutral unless ABLE or…

  34. CJC-1295

    5.0–5.5 /10 for better sleep 5.5–6.0/10 overall Neutral Growth Hormone Secretagogue

    Teichman 2006 reports CJC-1295 human pharmacology; supports sustained GH/IGF-1 increase and short-duration tolerability, not body-composition or longevity outcomes. Ionescu 2006 points in the same direction, but route, dose, baseline status, and outcome…

  35. Lion’s Mane

    4.5–5.0 /10 for better sleep 7.0–7.5/10 overall Strong recommend Functional Mushroom

    Sleep quality improved in Vigna 2019, but it was a secondary signal under diet co-intervention. Vivid dreams are common anecdotally and can be helpful or disruptive.

  36. Metformin

    4.5–5.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Metabolic & Glycemic Drug

    Metformin has no consistent sleep-quality signal. Improved glucose control may help some diabetic users, while GI effects can disrupt sleep during titration.

  37. Tongkat Ali

    4.5–5.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Adaptogenic Herb

    Sleep benefit is indirect through stress tone. In practice, evening dosing can disrupt sleep, and insomnia is one of the most consistent community side effects, so morning-only dosing matters.

  38. Full-Spectrum Hemp (CBD)

    4.5–5.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Botanical Extract (non-adaptogenic)

    Dedicated, high-quality CBD sleep RCTs are largely missing. The most cited human data is Shannon 2019, an uncontrolled case series where sleep scores improved in 67% of 72 patients at first but…

  39. Whole-Body Vibration

    4.5–5.0 /10 for better sleep 7.0–7.5/10 overall Strong recommend Vibration & Mechanical Stimulation

    No direct sleep RCTs; whole-body vibration may help indirectly when it functions like light exercise, but this is not a sleep-specific intervention.

  40. Ergothioneine

    4.5–5.0 /10 for better sleep 6.5–7.0/10 overall Worth trying Vitamin & Mineral & Nutrient

    Zajac 2025 reported a sleep-initiation signal at 25 mg/day, but this is one small industry-sponsored trial, so the effect is preliminary.

  41. Tesamorelin

    4.5–5.0 /10 for better sleep 6.0–6.5/10 overall Worth trying Growth Hormone Secretagogue

    Nick's personal review reports deeper sleep, and bedtime dosing matches nocturnal GH physiology. Controlled tesamorelin polysomnography evidence is absent, so this stays an experiential and mechanistic subrating rather than a clinical sleep…

  42. Rucking (Weighted Walking)

    4.0–4.5 /10 for better sleep 7.0–7.5/10 overall Strong recommend Cardiovascular

    Plausible. Daytime aerobic activity and outdoor light exposure support sleep, a general exercise and circadian effect rather than a rucking-specific one.

  43. Bromantane (Ladasten)

    4.0–4.5 /10 for better sleep 7.0–7.5/10 overall Strong recommend Synthetic Nootropic (non-racetam)

    Sleep-wake normalization was reported in Voznesenskaia 2010 as part of the asthenia outcome. Long half-life means PM dosing can compress sleep latency; community reports flag insomnia as the most common subjective AE.

  44. GlyNAC (Glycine + N-Acetylcysteine)

    4.0–4.5 /10 for better sleep 6.5–7.0/10 overall Worth trying Amino Acid

    Glycine alone has small trials supporting better subjective sleep quality and faster sleep onset, which carries into the stack, but this is a glycine effect rather than a GlyNAC-specific finding.

  45. Sprinting (Sprint Interval Training)

    4.0–4.5 /10 for better sleep 6.0–6.5/10 overall Worth trying Cardiovascular

    Morning or afternoon sprints are sleep-neutral or helpful, but late-evening maximal efforts can delay sleep onset in sympathetic-sensitive people; timing matters more than the format.

  46. Sermorelin (GHRH 1-29)

    4.0–4.5 /10 for better sleep 5.5–6.0/10 overall Worth trying Growth Hormone Secretagogue

    Sleep is the single most popular reason people run sermorelin, yet the controlled adult evidence is weak to negative, which keeps the score modest. GHRH at the class level can promote deep,…

  47. TRT (Testosterone Replacement Therapy)

    4.0–4.5 /10 for better sleep 5.5–6.0/10 overall Neutral Hormone Therapy

    TRT may improve energy and mood but can worsen sleep apnea in susceptible men. The Endocrine Society guideline lists untreated severe obstructive sleep apnea as a reason not to start therapy, so…

  48. MK-677 (Ibutamoren)

    4.0–4.5 /10 for better sleep 4.5–5.0/10 overall Neutral Research Compound

    Sleep is one of MK-677's more consistent and pleasant effects, which earns it a high score. In young subjects, Copinschi 1997 showed roughly a 50 percent increase in deep stage-IV sleep and…

  49. Hyperbaric Oxygen Therapy

    3.5–4.0 /10 for better sleep 5.5–6.0/10 overall Worth trying Hyperbaric

    Sleep improvement may occur indirectly through pain reduction, fatigue improvement, or recovery effects. It is not a primary high-confidence HBOT endpoint.

  50. Electrolytes

    3.5–4.0 /10 for better sleep 8.5–9.0/10 overall Top-tier Vitamin & Mineral & Nutrient

    Magnesium may support sleep onset and nighttime cramps in deficient users; sodium and potassium can reduce dehydration-linked wakeups. No strong evidence for broad sleep enhancement in replete users.

  51. Retatrutide

    3.5–4.0 /10 for better sleep 5.5–6.0/10 overall Neutral Metabolic & Incretin Peptide

    Weight loss may improve sleep apnea and reflux, but nausea, under-eating, and dysesthesia could disturb sleep in some users. No sleep-quality RCT endpoint justifies a higher score yet.

  52. Blood-Flow Restriction Training

    3.0–3.5 /10 for better sleep 8.0–8.5/10 overall Strong recommend Resistance & Strength

    Any sleep benefit is likely mediated by exercise and recovery, not a direct BFR effect.

  53. Astaxanthin

    3.0–3.5 /10 for better sleep 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Some users report better sleep, but no dedicated sleep-quality RCT base.

  54. Selank

    3.0–3.5 /10 for better sleep 6.5–7.0/10 overall Worth trying Neuropeptide

    Anxiety reduction may improve sleep onset in anxious users. There are no polysomnography or sleep-architecture trials, and the non-sedating profile means Selank should not be treated as a sleep drug.

  55. NMN (Nicotinamide Mononucleotide)

    3.0–3.5 /10 for better sleep 6.0–6.5/10 overall Worth trying Exogenous Metabolite

    Sleep data are weak. Yamaguchi 2024 studied metabolism and sleep in healthy middle-aged Japanese men, but the practical signal remains mixed, and late dosing can worsen insomnia.

  56. DSIP (Delta Sleep-Inducing Peptide)

    3.0–3.5 /10 for better sleep 6.0–6.5/10 overall Worth trying Neuropeptide

    Sleep quality is the headline claim and the reason most people buy DSIP, but the two cleanest independent double-blind PSG trials found the effect weak and of little clinical significance, per Bes…

  57. Exogenous Ketones

    3.0–3.5 /10 for better sleep 5.5–6.0/10 overall Worth trying Exogenous Metabolite

    No dedicated sleep evidence; the Leuven overload protocol used a pre-sleep dose for recovery, not for sleep quality itself.

  58. Quinton Marine Plasma (Seawater Minerals)

    3.0–3.5 /10 for better sleep 5.5–6.0/10 overall Worth trying Vitamin & Mineral & Nutrient

    No controlled sleep data. Any benefit would be an indirect magnesium effect at a small dose.

  59. CJC-1295 No DAC (Mod GRF 1-29)

    3.0–3.5 /10 for better sleep 5.5–6.0/10 overall Worth trying Growth Hormone Secretagogue

    Sleep is the most consistently reported benefit and the main reason people stay on the stack, but it is not proven for CJC-1295 alone. The signal comes from the CJC plus ipamorelin…

  60. Cold Plunge

    3.0–3.5 /10 for better sleep 5.5–6.0/10 overall Neutral Cold Exposure

    Cain 2025 PLOS ONE meta-analysis (n=3,177) pooled signal favoring improved subjective sleep quality in non-clinical samples; effect size was modest but directionally positive. Robey 2013 polysomnography (n=11 male cyclists) showed evening post-exercise…

  61. MK-777 (Acetamoren)

    3.0–3.5 /10 for better sleep 4.5–5.0/10 overall Neutral Research Compound

    The parent improved slow-wave and REM sleep in a controlled trial. That is the most defensible inherited claim, but it was never shown for MK-777.

  62. C15 (Pentadecanoic Acid)

    3.0–3.5 /10 for better sleep 3.0–3.5/10 overall Caution Vitamin & Mineral & Nutrient

    No C15:0 trial has measured sleep quality, actigraphy, polysomnography, insomnia scales, or sleep timing. Robinson 2024 (Robinson 2024) and Chooi 2024 TANGO did not include sleep as a primary or convincing secondary…
