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 survival

What this outcome means

Overall survival measures how long people stay alive across a study's follow-up period, with longer survival counted as the better result. On DoseRank it maps to a defined health outcome built from human studies on time-to-event survival data, mortality rates, and follow-up duration – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Serious diagnosesPeople facing major conditions where long-term survival is the priority.

Long-term outlookThose weighing what shifts survival odds over years of follow-up.

Evidence-focused readersAnyone who values hard mortality endpoints over softer measures.
