Methylene Blue

A prescription dye and monoamine-oxidase inhibitor studied in narrow medical and experimental contexts—not a routine dietary supplement.

Evidence verdict

Insufficient evidence for the stated context. The human nootropic evidence is extremely small, product purity is critical and self-dosing can cause serious interactions or toxicity.

Clinical dye indicationsExperimental cognition researchMitochondrial claims
02

Main benefits

  • One small randomized imaging study reported acute brain-activity and memory signals in healthy adults.
  • The human nootropic evidence is extremely small, product purity is critical and self-dosing can cause serious interactions or toxicity.
03

Studied protocols

Research doses are grouped by outcome. They describe study designs—not a personal prescription.

Clinical dye indications

No self-use dose established; prescription and investigational contexts only

Very low confidence
Study duration
Commonly 4–12 weeks; protocol and outcome vary
Interpretation
The human nootropic evidence is extremely small, product purity is critical and self-dosing can cause serious interactions or toxicity.

Clinical or experimental context—professional guidance is especially appropriate.

04Food sources & equivalents
Food sources & equivalents

Can food provide a studied amount?

No direct food equivalent
Comparison targetNo self-use dose established; prescription and investigational contexts only

Methylene Blue in this supplemental form does not have a reliable one-to-one food equivalent.

No food equivalentFood amount varies

Dietary exposure; verify composition before comparing with a studied supplement dose

How this was estimated
Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
Important limitation
Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.

Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

05How to take it for absorption & tolerance
Meal relationship

With or without food

Evidence-informed
With or without food; formulation and tolerance remain part of the comparison.

Human research has not established a universally superior fed or fasted protocol for this ingredient.

Practical approach
Clinician-directed only. Keep the formulation and daily total consistent with the evidence context shown above.
Watch for
SSRIs, SNRIs, MAO inhibitors and other serotonergic medicines

Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.

06Supplement interaction check
Library interaction context156 ingredients · 0 mapped signals for this guide

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.

No pair-specific signal listedNo established interaction with another Dose Radar ingredient was identified in this review.

This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.

07Research notes
Evidence verdict

Insufficient evidence for the stated context. The human nootropic evidence is extremely small, product purity is critical and self-dosing can cause serious interactions or toxicity.

The displayed amount comes from human research or an official evidence summary. It is not a personalized prescription, and formulation can change whether the comparison is valid.
