About This Product

What Is Methylene Blue?

Long History of Use

Methylene blue was first synthesized in 1876 and has one of the longest pharmaceutical histories of any synthetic compound. It was the first fully synthetic drug used in medicine and has been on the WHO's list of essential medicines.

USP Grade Purity

USP (United States Pharmacopeia) grade indicates this solution meets the stringent purity and quality standards set by the US Pharmacopeia — the same standards required for pharmaceutical products. This distinguishes it from lower-purity industrial or laboratory grades.

Growing Research Interest

Methylene blue has become a subject of significant interest in the wellness and biohacking communities due to emerging research into its potential role in mitochondrial function, cognitive support, and antioxidant activity. Research is ongoing and evolving.

Important Safety Information

Methylene blue is a potent compound that can interact with certain medications, particularly serotonergic drugs (SSRIs, MAOIs, and others). It should not be used without consulting a qualified healthcare provider, especially if you take any prescription medications. Methylene blue can stain skin, clothing, and surfaces. Do not use if pregnant or nursing without medical supervision. This product is not intended to diagnose, treat, cure, or prevent any disease. Keep out of reach of children. Always consult your healthcare provider before use.

About Zatural Methylene Blue 1% USP Grade

Zatural's Methylene Blue is a 1% aqueous solution of methylene blue manufactured to USP (United States Pharmacopeia) grade standards — the same purity benchmark used for pharmaceutical products. The 1% concentration is one of the most commonly referenced concentrations in wellness applications, providing a known, consistent dose per drop.

Methylene blue's distinctive deep blue color is characteristic of the compound. It is water-soluble and absorbs readily — it will temporarily stain skin, teeth, and clothing on contact, which is a normal property of the compound and not a product defect.

This product is part of Zatural's Specialty line — products outside the core hemp and CBD category that appeal to the wellness and biohacking community. It is manufactured in the USA to the same GMP and quality standards as Zatural's other products.

Common Questions

Zatural Methylene Blue — FAQ

Important information before you buy.

What does USP grade mean?

USP (United States Pharmacopeia) grade indicates that a substance meets the purity, quality, and strength standards established by the United States Pharmacopeia — a non-governmental scientific organization that sets standards for medicines, food ingredients, and dietary supplements in the USA. USP grade is a higher standard than reagent or laboratory grade, and is used for pharmaceutical applications.

Can methylene blue interact with medications?

Yes — methylene blue has known interactions with serotonergic medications including SSRIs, SNRIs, MAOIs, and other drugs that affect serotonin levels. Combining methylene blue with these medications can potentially cause serotonin syndrome, a serious condition. Always consult your healthcare provider before using methylene blue if you take any prescription medications.

Why does methylene blue stain everything blue?

Methylene blue is an intensely pigmented compound — its characteristic deep blue-green color is fundamental to the molecule's chemistry. Contact with skin, teeth, clothing, or surfaces will result in temporary blue staining. On skin, this typically fades within 24–48 hours. Handle with care and avoid contact with fabrics or porous surfaces you don't want stained.

Is this the same as the methylene blue used in fish tanks?

No — aquarium-grade methylene blue is manufactured to a much lower purity standard and may contain contaminants not acceptable for human use. Zatural's methylene blue is USP grade — manufactured to pharmaceutical purity standards. Never use industrial, aquarium, or laboratory-grade methylene blue for wellness purposes.

Should I consult a doctor before using this?

Yes — we strongly recommend consulting a qualified healthcare provider before using methylene blue, particularly if you take any medications, have a health condition, are pregnant or nursing, or have G6PD deficiency. Methylene blue is a potent compound with known drug interactions. This product is not intended to diagnose, treat, cure, or prevent any disease.

Is this third-party tested?

Yes — all Zatural products are manufactured in GMP-compliant facilities in the USA. The USP grade designation means this product meets established pharmaceutical purity standards. Check the Zatural website for current Certificate of Analysis information.
