Every intervention Outliyr has scored for better sleep, ranked by its BioHarmony score for this use case rather than its overall rating. The number beside each name is how well that one thing works for better sleep; the tier beside it is what it is worth once safety, cost and effort are counted across everything else.
61 of 113 evaluated interventions score 3.0+ out of 10 for better sleep · 23 comparisons
Magnesium sleep quality earns 8.6/10 because 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.…

Ionescu 2006 points in the same direction,…

Read the Whole-Body Vibration report →Zajac 2025 reported a sleep-initiation signal at 25 mg/day, but this is one small industry-sponsored trial, so the effect is preliminary.
Read the Ergothioneine report →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…
Read the Tesamorelin report →Plausible. Daytime aerobic activity and outdoor light exposure support sleep, a general exercise and circadian effect rather than a rucking-specific one.
Read the Rucking (Weighted Walking) report →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.

Head-to-head reports and category rankings that name a winner on this use case.
Tesamorelin, at 6.2, and only if you have a clinical reason. Every one of the nine scores 6.2 or lower, so the category tops out at worth trying…
Melatonin, dosed low. It scores 8.2 against apigenin's 6.7 and wins the sleep rows outright. The morning hangover apigenin markets against comes from taking too much, not from…
Both score anxiety 7.5, so the tie-breaker is time. L-theanine works in about an hour and you take it when you need it. Ashwagandha takes eight weeks and…
Bromantane, for anything you plan to repeat. It scores 7.1 against phenylpiracetam's 5.5 and wins every shared use case that is not a floor tie: energy 6.2 to…
These two get sold as the same thing, a scoop for gut and skin, and they share almost no mechanism. Colostrum is a gut and immune product: gut…
CoQ10 scores 7.1 and methylene blue 6.1, yet methylene blue wins eleven of the seventeen shared use cases. The overall gap is risk, not effect. Methylene blue inhibits…
Neither, yet. Both have zero human trials, zero human pharmacokinetics and research-only access. PE-22-28 scores 4.9 and dihexa 4.4, and the gap is entirely safety: dihexa potentiates the…
Epitalon, if sleep is the question. It scores sleep quality 6.5 against pinealon's 1.7, because it acts on the pineal gland and melatonin output while pinealon is a…
Magnesium glycinate is magnesium bound to glycine, so if you take it you already take both. That kills the question for sleep. The real decision: magnesium scores higher…
Lion's Mane scores 7.2 and the reishi, cordyceps and chaga blend category scores 5.8. If cognition is the goal, buy the one species: lion's mane takes cognition-focus 7.0…
Start on sermorelin. Ipamorelin scores higher overall, yet sermorelin wins thirteen of the sixteen shared use cases and it is the one an anti-aging clinic actually prescribes. Ipamorelin…
Shilajit scores 7.4 and ashwagandha 6.8, but that gap is the least useful number here. These two do different jobs. Shilajit is the mineral and androgen play: male…
Magnesium, at 8.6 out of 10 for better sleep. Magnesium sleep quality earns 8.6/10 because Mah 2021 anchors the most relevant signal.
Of the top-scoring options, Glycine is the least expensive at about $2 a month, scoring 8.5 out of 10 for better sleep.
61 of the 113 interventions evaluated for better sleep score 3.0 out of 10 or better, which is the cut-off for appearing on this page.
