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.

Reduce cough

What this outcome means

Cough severity is how often and how forcefully you cough, and how much it disrupts talking, sleeping, or getting through the day. On DoseRank it maps to a defined health outcome built from human studies on cough frequency counts, severity rating scales, and symptom-related quality of life – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Lingering tickleA nagging cough that hangs on after the bug clears.

Sleep-disrupting coughNight-time fits that break sleep and leave you drained.

Talk-interrupting boutsFrequent coughing that cuts into meetings and conversations.
