Is a higher dose always better?

No. Dose-fit rewards landing inside the range studied for the outcome — over-dosing (common with melatonin) or under-dosing both lower the score. The goal is the effective dose, not the biggest number.

What does the Value score mean?

The Value score compares a product's price per serving with clinically relevant products ranked for the same outcome. A score of 50 is the typical price; above 50 means better value than typical, while below 50 means the product costs more than typical. It is a 0–100 value signal, not a percentile.

Why is the cheapest product not #1?

Cost is only one input. The cheapest pick here is a citrate form with weaker absorption and a stock-risk flag, so it leads on Value-for-cost but trails on the composite that also weighs evidence, dose fit and availability.

Are these affiliate links?

Retailer links may be affiliate links and DoseRank may earn a commission. Rankings and placement are determined by the scoring model only — never by payment from a brand.

Is this medical advice?

No. DoseRank summarizes evidence to help you choose; it is not a substitute for a clinician, especially if you are pregnant, breastfeeding, on medication, or managing a health condition.

Improve sleep quality

What this outcome means

Sleep quality is how restful and restorative your nights actually feel, from how soundly you stay asleep to how refreshed you wake. On DoseRank it maps to a defined health outcome built from human studies on sleep efficiency, nighttime awakenings, and next-day restfulness ratings – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Restless nightsTossing and turning that leaves sleep feeling shallow and broken.

Light sleepersEasily roused by noise, light, or a restless partner.

Unrefreshed morningsWaking groggy and drained despite spending enough hours in bed.

Stack buildersAlready taking supplements such as Melatonin or L-Theanine and want the dose right.

Evidence level

Dose matchedDoseFit 78

Scores reward products dosed inside or above the studied range, not just the right ingredient. Examples: In range: L-Theanine 200 mg vs 200-400 mg, Hops 100 mg vs 100-500 mg; Above range: Melatonin 5.5 mg vs 1-5 mg; Below range: Lemon Balm 100 mg vs 300-1200 mg, Chamomile 150 mg vs 200-1000 mg.

Thin spots

Hops and GABA have low evidence for this outcome, so they are flagged as evidence gaps rather than treated as proven drivers.
