What is methylene blue?

Methylene blue, also known as methylthioninium chloride, is a synthetic compound used in medicine, laboratories and industrial applications. Medical methylene blue has recognised uses under professional supervision, but these do not establish the safety or effectiveness of retail oral solutions for cognitive enhancement.

Research has explored its effects on cellular and mitochondrial processes, but evidence does not currently support promising improved memory, treatment of brain fog or prevention of age-related cognitive decline.

Directions

Because methylene blue is pharmacologically active and may cause serious interactions, a self-directed oral dose should not be published without verified instructions and professional oversight.

Recommended wording for the page:

Use only as directed on the current product label and under the guidance of a qualified healthcare professional. Do not exceed the recommended amount. The dropper should be measured carefully because concentration and drop size directly affect the amount used.

Do not publish a short list of antidepressant brand names as if it were complete. Customers should be instructed to show their full medication list to a doctor or pharmacist.

G6PD deficiency warning

Methylene blue can cause haemolysis or haemolytic anaemia in people with G6PD deficiency. People with known or suspected deficiency should not use it without specialist medical advice.

Pregnancy and breastfeeding

Methylene blue may harm the fetus and should not be used during pregnancy without a clear medical indication and specialist supervision. Breastfeeding users should seek medical advice before use.

Frequently Asked Questions

What concentration is this product?

It contains methylene blue at a concentration of 0.5%, equivalent to 5 mg per mL.

Is this the 0.5% or 1% version?

The displayed product and label indicate 0.5%. The current URL incorrectly includes “1%” and should be corrected with a 301 redirect.

What does USP grade mean?

It indicates that the ingredient is intended to meet identity and purity specifications established by the United States Pharmacopeia. It does not mean the product is approved for cognitive enhancement or other wellness claims.

Is Compass Laboratory Methylene Blue FDA approved?

The page should not claim that this retail solution is FDA approved. An injectable methylene blue medicine is approved for specific medical use, but that approval does not cover this product for memory, brain health, energy or anti-ageing.

Can methylene blue improve memory or focus?

Research is preliminary and does not establish that this product improves memory or focus in healthy adults. Results should not be promised, and medical advice is necessary before use.

Can it be used with antidepressants?

It may interact dangerously with antidepressants and other serotonergic medicines. Combining them can cause serotonin syndrome. A doctor or pharmacist must review the customer’s complete medication list before use.

Who should avoid methylene blue?

People with G6PD deficiency, pregnant or breastfeeding users, children, and anyone taking serotonergic medicines should avoid self-use and obtain specialist medical advice.

Why is the bottle made of amber glass?

Amber glass helps reduce exposure to light and avoids prolonged contact with plastic. The bottle should remain tightly closed in a cool, dry place.

Can it change the colour of urine or the tongue?

Yes. Blue or blue-green discolouration of the tongue, mouth or urine can occur. However, unexpected or severe symptoms still require medical assessment.

How should the dose be measured?

Only follow the verified label and professional instructions. Do not assume every dropper produces the same drop size, and do not calculate a dose from online recommendations.
