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 wound healing

What this outcome means

Wound healing is how quickly and cleanly your skin and tissue repair after a cut, scrape, or surgical incision. On DoseRank it maps to a defined health outcome built from human studies on wound closure time, tissue repair quality, and healing rates – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Slow to closeCuts and scrapes that linger far longer than expected.

Post-surgical recoveryIncisions that need to knit cleanly after an operation.

Chronic woundsPersistent ulcers or sores that resist normal healing.

Stack buildersAlready taking supplements such as Zinc Gluconate and want the dose right.
