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 vitamin B6 status

What this outcome means

Vitamin B6 status reflects whether your body carries enough of this vitamin and its active forms to support the reactions that rely on it. On DoseRank it maps to a defined health outcome built from human studies on plasma PLP concentration, dietary B6 intake, and B6-dependent enzyme markers – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Limited dietsRestricted or repetitive eating that leaves B6 intake on the low side.

Higher demand stagesPregnancy or illness that raise the body's day-to-day B6 needs.

Reviewing bloodworkPeople checking lab panels who want B6 sitting in a sufficient range.
