What does a 1% methylene blue solution mean?

A 1% solution contains 10 mg of methylene blue per milliliter. In this calibrated dropper system, that equals approximately 0.5 mg per drop and 10 mg per full dropper.

How much methylene blue is in each drop and full dropper?

Each measured drop delivers 0.5 mg of methylene blue. Ten drops provide 5 mg, while approximately 20 drops—or one full dropper—provide 10 mg.

How should I measure and take it?

Use the included glass pipette to count drops or measure a full dropper. Your selected amount can be taken directly or mixed into water or juice.

How long does one bottle last?

A 50 mL bottle provides approximately 100 servings when measured at 5 mg, or 10 drops, per serving.

Can the liquid stain?

Methylene blue is vividly colored and can stain skin, fabric and surfaces. Handle the pipette carefully and clean spills promptly.

How is the methylene blue tested?

NooBlue’s methylene blue ingredient is independently analyzed by CTLA for identity and heavy metals.

How should it be stored?

Keep the bottle tightly closed in a cool, dry place away from direct heat and sunlight.

Should I choose drops, capsules or gummies?

Choose drops for maximum dosing control, capsules for precise neutral convenience, or gummies for an easy chewable ritual.

HOW IT WORKS

Supports the energy behind cognition.

Methylene blue’s reversible redox activity helps move electrons through the cellular environment that produces energy.

Accepts electrons

Methylene blue begins the cycle in its oxidized state.

Cycles between redox states

The molecule can move between oxidized and reduced forms.

Supports electron transport and ATP

The cycle supports the mitochondrial pathways behind cellular energy.
