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.

What this outcome means

Depressive symptoms cover persistent low mood, loss of interest in things you used to enjoy, and the heavy, flat feeling that colors everyday life. On DoseRank it maps to a defined health outcome built from human studies on validated depression rating scales, mood severity scores, and anhedonia measures – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Lost interestActivities and people that once felt rewarding now leave you indifferent.

Seasonal dipsMood that sinks with darker months or shorter daylight hours.
