Inside the formula
Two actives, one precise capsule—and a serious interaction warning.
Methylene blue has pharmacologic activity and is not an everyday blue antioxidant. This formula pairs 10mg USP-grade methylene blue with 10mg ascorbic acid and explains both the research and the risks.
1 capsule per serving10mg methylene blue + 10mg ascorbic acid
Supporting active
Ascorbic acid
10mg vitamin C is included as a reducing antioxidant within the formulation.
Safety
Interactions come first
Methylene blue can inhibit monoamine oxidase A and can be dangerous with serotonergic medicines.
01
10mg
Human evidence · small acute study
The pharmacologically active compound
Methylene Blue
USP-grade methylthioninium chloride
What it is: Methylene blue is a redox-active compound with established medical uses at clinician-directed doses and growing experimental research in other areas.
Evidence context: A small placebo-controlled fMRI study found changes in memory-related measures after a single low dose in healthy adults. It does not establish daily cognitive enhancement or long-term safety.
How it fits the formula
Read the human fMRI studyThe capsule provides a fixed amount, avoiding drop-count ambiguity, but precision does not remove contraindications or drug interactions.
02
10mg
Formulation rationale · exact pair untested
The reducing antioxidant
Ascorbic Acid
Vitamin C
What it is: Ascorbic acid is vitamin C and a reducing agent. At 10mg, it is a small formulation component rather than a high-dose vitamin C supplement.
Evidence context: The label does not cite a study of this exact methylene-blue/ascorbic-acid pair. Its inclusion should be described as formulation rationale, not proven cognitive synergy.
How it fits the formula
Ascorbic acid contributes redox chemistry alongside methylene blue; the exact in-vivo effect of this pairing has not been demonstrated for the finished capsule.
Every other label-listed ingredient
What the supporting ingredients actually do.
Rice flour
An inactive carrier used for consistent capsule fill.
Cellulose capsule
The plant-derived capsule shell.
The formulation rationale
A redox pairing, not a proven nootropic stack.
Fixed dose + capsule format: The 10mg methylene-blue amount is pre-measured, reducing liquid drop-count variability.
Methylene blue + vitamin C: The compounds have complementary redox roles, but this exact pair has not been clinically tested for cognition or energy.
Research interest + safety boundary: A small acute study cannot establish safe daily use, long-term effects or compatibility with medication.

- What It Does
Each capsule supplies 10mg USP-grade methylene blue and 10mg ascorbic acid. USP describes a raw-material quality specification; it is not a claim about the effects of this supplement.
- How It Works
Methylene blue is redox-active and has pharmacologic effects, including monoamine oxidase A inhibition at relevant exposures. A small acute human study is not evidence of daily cognitive enhancement, and medication interactions are a primary safety consideration.
- 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 low dose was associated with changes in memory-related measures and functional imaging. The study does not establish long-term benefit or safety for daily supplementation.

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 specifically directed by a qualified prescriber; serotonin syndrome can be life-threatening. It may also be unsafe in G6PD deficiency, pregnancy or breastfeeding. Seek clinician guidance before use.
Follow the physical label exactly. Do not use with serotonergic medicines unless specifically directed by a qualified prescriber. Review all contraindications before use.
