Common questions

Find answers to the most common questions about methylene blue, including its benefits, usage, and potential effects.

Methylene blue benefits and usage

How does methylene blue boost energy and cognition?

Methylene Blue works by improving mitochondrial function, increasing cellular energy, and enhancing brain function. It supports cognitive performance, mental clarity, and mood stability, making it an excellent supplement for overall vitality.

Is blu flo methylene blue safe?

Yes. Our product is USP-grade Methylene Blue and is third-party lab tested for purity and potency.

Clinical research shows that doses (typically under 2 mg/kg) are well tolerated. However, as with any supplement, it’s important to follow dosing recommendations and consult your healthcare provider if you have any health concerns.

How should I take methylene blue for optimal results?

Find your perfect dosage
Begin with 1–5 drops of a 1% methylene blue solution diluted in liquid (approximately 0.5–2.5 mg).
If well tolerated, gradually increase your dose to 10–40 drops based on your body’s response.
Always listen to your body and adjust accordingly. Start low and work your way up. If you're unsure, consult with a healthcare professional before use. 

Tips

  • Mix with juice to mask the bitter taste.
  • Use a straw and rinse your mouth afterward to minimise temporary staining.
  • Take periodic breaks (e.g., two days off each week).
  • For faster absorption, take on an empty stomach.

Can I combine blu flo methylene blue with other supplements or medications?

If you’re already taking other supplements or medications—especially those affecting serotonin or dopamine (such as MAO inhibitors, SSRIs, or SNRIs)—we strongly recommend consulting a healthcare professional before adding Methylene Blue. 

It’s also not advised for pregnant or breastfeeding women or individuals with renal impairment.

Always consult a professional for personalised advice before taking Methylene Blue products.

How long until I feel the effects of methylene blue?

Many people report feeling improved focus and energy within 24–48 hours of use. Some even notice benefits, such as enhanced mental clarity, in as little as 30 minutes. As always, individual responses may vary, and consistent use often leads to more pronounced benefits over time.

Does methylene blue cause jitters like caffeine or pre-workout supplements?

No, methylene blue provides clean energy without the jitters or crashes often associated with stimulants like caffeine.

Will methylene blue stain my teeth or affect my smile?

For those with natural teeth, any temporary blue tint typically fades after rinsing. However, if you have dentures or veneers, there is a risk of more persistent staining, so please consider this before use.

Is blu flo methylene blue safe for daily use?

Yes, Blu Flo Methylene Blue is safe for daily use when taken as directed. Our USP-grade formulation is designed to support consistent cognitive and physical performance at therapeutic doses. For optimal results and to minimise potential risks, we recommend taking periodic breaks—such as two days off each week. As always, consult your healthcare provider if you have any concerns or are taking other medications.

What is the best time of day to take methylene blue?

Since Methylene Blue supports energy production by enhancing cellular respiration, many users prefer taking it in the morning. However, some find that taking it later in the day doesn’t interfere with sleep. For prolonged focus, you might consider splitting your dose between morning and early afternoon. Experiment to discover what best suits your routine.

Can I take more than the recommended dosage of methylene blue?

We advise starting with 5 drops per day and only increasing gradually if needed. Exceeding the recommended dose without consulting a healthcare professional is not recommended. Always listen to your body and adjust carefully.
