Inside the formula
Corrected to the label: 1% solution, not 0.5%.
The supplied bottle label states a 1% solution, 500mcg per drop and 10mg per full dropper. Those values now replace the conflicting 0.5% claim previously shown on this page.

The redox-active compound
Methylene Blue
USP-grade methylthioninium chloride · 1% solution
What it is: Methylene blue is a pharmacologically active, redox-cycling compound with established clinician-directed medical uses and experimental research in other settings.
Evidence context: A small acute human fMRI study reported changes in memory-related measures after a single dose. It does not establish an optimal wellness dose or safe long-term use.
How it fits the formula
Read the human fMRI studyThe liquid format enables small measured amounts, but drop size can vary with technique and the product still carries serious interaction risks.

What the supporting ingredients actually do.
No additives declared
The supplied label states “no additives.” No additional active ingredient is presented on this page. Follow the bottle in hand for the complete ingredient statement.
The formulation rationale
Precision requires more than a percentage.
Concentration + per-drop amount: The 1% statement is paired with 500mcg per drop so the liquid can be interpreted in actual amounts.
Drop + dropper scale: A full dropper is labeled as 10mg, providing a second reference point; count carefully and follow the physical label.
Flexible format + serious caution: Customizable measurement can also increase error risk. Medication screening matters before use.

- What It Does
The supplied label identifies this as a 1% USP-grade methylene blue solution, providing 500mcg per drop and 10mg per full dropper, with no additives declared.
- How It Works
Methylene blue is redox-active and pharmacologically potent. Liquid dosing allows smaller measured amounts but can introduce drop-size variability, and serious serotonergic drug interactions remain relevant.
- Science-Backed Research
Evidence tier is identified for each active ingredient
Human, preclinical and formulation evidence are kept separate
Primary-source research is linked in the ingredient breakdown
The exact finished formula is not presented as clinically tested
- Ideal For
Adults who have reviewed methylene blue with a qualified clinician
Shoppers who need the concentration and dose stated precisely
People who have screened for medicine interactions and contraindications
- Clinical Research
Small placebo-controlled fMRI study in healthy adults
A single dose was associated with changes in selected memory and imaging measures. It does not establish an optimal daily dose, long-term benefit or long-term safety.

The supplied label identifies this as a 1% USP-grade methylene blue solution, providing 500mcg per drop and 10mg per full dropper, with no additives declared.
Methylene blue is redox-active and pharmacologically potent. Liquid dosing allows smaller measured amounts but can introduce drop-size variability, and serious serotonergic drug interactions remain relevant.
No finished-product clinical trial is cited. The research links provide ingredient-level context and are labeled by evidence type. Do not use methylene blue with SSRIs, SNRIs, MAO inhibitors or other serotonergic drugs unless directed by a qualified prescriber; serotonin syndrome can be life-threatening. It may also be unsafe in G6PD deficiency, pregnancy or breastfeeding. The product can permanently stain surfaces and fabrics.
Follow the physical label exactly. Do not use with serotonergic medicines unless specifically directed by a qualified prescriber. Review all contraindications before use.
