Methylene blue is an electron cycler that supports mitochondrial efficiency and cellular resilience.
Energy at the source
Facilitates electron transport to help mitochondria make ATP more efficiently.
Calm, steady focus
Supports balanced neurotransmitter signaling for clarity without stimulants.
Antioxidant defense
Redox support helps neutralize oxidative stress that drags down cognition and mood.
1
Prime mitochondria
Acts as an alternative electron carrier, keeping the electron transport chain efficient.
2
Reduce oxidative drag
Helps quench reactive oxygen species, protecting cellular structures and neurotransmitters.
3
Sustain clarity & mood
Supports balanced signaling for focus, memory, and resilience—without jitter.
What to expect
Day 1
Many feel noticeable clarity and steadier energy within ~30 minutes of the first dose.

Month 2+
Effects compound with consistent dosing; sustained clarity, energy, and resilience continue to deepen.
Feel it or it’s free.
90 days to experience clarity, steady energy, and resilience—or your money back.
Start nowHow to use
Dosing
Start: 0.5–1 mg/kg daily (commonly 5–10 drops of our solution) in water.
Timing: Morning or early afternoon to avoid late-day stimulation.
Pro tip: Rinse your mouth after dosing to minimize temporary blue tint; avoid spilling on fabric.
Safety first
Avoid if: pregnant/nursing, G6PD deficiency, or on SSRIs/SNRIs/MAOIs or other serotonergic meds without clinician oversight.
Interactions: Do not combine with serotonergic drugs or if advised otherwise by your physician.
What’s inside (and not)
Formula: USP-grade methylene blue, purified water, glycerin.
Free from: parabens, fragrances, artificial colors (the blue hue is the active), animal products, GMOs.
Minimalist by design—only what’s required for purity, stability, and dosing accuracy.

FAQs
Is this USP-grade or aquarium grade?
It is USP/pharmaceutical-grade methylene blue. Every lot is HPLC-verified for identity/purity and screened for heavy metals and microbes. We do not use industrial or aquarium-grade material.
Will it stain?
Methylene blue can stain, so dose carefully and avoid contact with fabrics. Rinse your mouth after dosing to reduce temporary oral tint.
Can I take this with my medications?
Do not combine with SSRIs, SNRIs, MAOIs, or other serotonergic drugs without clinician supervision. If you are on any prescription medication, consult your healthcare provider before use.
How quickly will I feel it?
Many notice mental clarity within ~30 minutes of the first dose. Benefits build with daily use over subsequent weeks.
What if it doesn’t work for me?
You’re covered by our 90-day money-back guarantee. If you don’t feel the benefits, contact us for a refund.
