Methylene blue is a compound with a long history of use in medical and research settings. It has also been studied for its role in cellular redox activity and mitochondrial energy production.

FocusBlu uses USP-grade methylene blue at a precise 1% concentration in a five-ingredient formula designed to support mitochondrial function, mental clarity, focus, and steady cellular energy.*

USP Grade means the methylene blue meets quality standards established by the United States Pharmacopeia.

A 1% concentration means FocusBlu® contains methylene blue at a precise 1% strength.

FocusBlu® contains five disclosed ingredients: Methylene Blue USP, USP Purified Water, USP Glycerin, Liposomal Vitamin C, and Stevia.

Every small batch is third-party tested, with a Certificate of Analysis published so you can verify the quality before you buy.

Start gradually and follow the suggested use on the label.

Week 1: 5 drops
Week 2: 10 drops
Week 3 and beyond: up to 20 drops

Take FocusBlu® five days on and two days off, preferably earlier in your day.

FocusBlu® can be mixed into water, juice, coffee, tea, or a daily vitamin drink. Methylene blue naturally has a distinct bitter taste, so many people prefer to mix it into another beverage.

Our founder adds her FocusBlu dose to her liquid vitamins by Rho Nutrient and says she cannot taste the methylene blue when taken that way.

For a more pleasant taste, grape, cranberry, or orange juice can also help mask the natural bitterness.

Methylene blue may temporarily stain the mouth, teeth, fabrics, or surfaces, so use care when handling.

Do not combine FocusBlu® with energy drinks or high-stimulant pre-workout products.

Always follow the suggested use on the label or guidance from your healthcare provider.

Most people incorporate FocusBlu® into their morning routine.

Because individual responses vary, we recommend taking it earlier in the day and following the gradual suggested-use schedule on the label.

Consistency matters more than chasing an immediate effect.

Everyone responds differently. Some customers report noticing changes in focus, clarity, or steady energy sooner, while others notice more gradual changes with consistent use.

This is one reason our suggested use gradually increases during the first three weeks. Starting low gives you time to become familiar with FocusBlu® while observing how your body responds.

For the clearest comparison, give your routine a full 30 days and evaluate how you feel compared with where you started.

Individual experiences vary based on factors including sleep, nutrition, body chemistry, medications, lifestyle, and overall health.

FocusBlu is formulated to support:

Yes. Methylene blue can interact with certain medications and should be used carefully.

Do not use FocusBlu® without first talking with your healthcare provider if you take medications that affect serotonin, including:

• SSRIs
• SNRIs
• MAOIs
• Certain other antidepressants or serotonergic medications
• Certain opioid pain medications, including tramadol, fentanyl, and methadone
• Dextromethorphan, found in some cough and cold medications
• Other medications that may affect serotonin

Combining methylene blue with serotonergic medications may increase the risk of serotonin syndrome, which can be serious.

If you take any prescription medication, talk with your doctor or pharmacist before using FocusBlu®.

This list is not exhaustive.

When used appropriately, methylene blue is generally well tolerated by many people. However, it can cause side effects and may interact with certain medications.

Methylene blue can be especially dangerous when combined with some serotonergic medications, including certain antidepressants and opioids, because of the risk of serotonin syndrome. It should also not be used by individuals with G6PD deficiency unless directed by a healthcare professional.

Always follow the suggested use on the label and consult your doctor or pharmacist before use if you take prescription medications, have a medical condition, are pregnant or breastfeeding, or are unsure whether methylene blue is appropriate for you.
