Methylene Blue should be taken orally or sublingually, depending on the formulation. It is best taken with food and plenty of water. Always follow your provider's recommended dose, as high doses can be toxic. Avoid taking it with SSRIs or serotonin-boosting medications unless approved by your healthcare provider.

Some users may experience blue or green discoloration of urine, mild nausea, headache, or dizziness. These are generally harmless and temporary. High doses or interactions with certain medications can lead to serious side effects—consult a provider before use.

Emerging research suggests methylene blue may help restore mitochondrial function and reduce oxidative stress, which is critical in recovery from long COVID and some chronic conditions. It may also enhance the effectiveness of certain cancer therapies by improving cellular energy and oxygenation. Always consult a medical professional for personalized advice.

Low doses of pharmaceutical-grade methylene blue may be used daily under supervision. However, long-term or high-dose use without guidance can lead to toxicity. It should be cycled or paused periodically based on your healthcare provider’s advice.

Store in a cool, dry place away from sunlight. Make sure the container is tightly sealed, and keep it out of reach of children and pets. Due to its staining nature, handle with care.
