Best Customers & Best Results
Emma Johnson
Works perfectly as described. The mental clarity is spot‑on and lasts for a few hours. I’ll admit I just took the tincture directly and followed it with water—my tongue was blue for a few hours (water and time take care of that). I could breathe more easily, and the energy boost made for a fantastic pre‑workout.As for the people complaining about arsenic levels—please learn how to do scientific math. P.S. There’s more arsenic in your average bottled water.

Works exactly as described. The mental clarity is right on point and lasts for a few hours. I’ll admit I just took the tincture straight and chased it with water—my tongue was blue for a few hours (water and time take care of that).

My wife and I have been using this since early November, and now I wouldn’t go without it. I highly recommend it—just be careful not to use too much. I take one or two drops in the morning, occasionally, directly under the tongue, and the effect is noticeable: it gives me energy and clearer thinking. It aids mitochondrial ATP production and metabolism. Also, it’s antipathogenic, so it may cleanse the gut microbiome; therefore, you might want to take probiotics at night if you take methylene blue in the morning.
Olivia Williams
The product arrived on time and seems to be exactly as advertised. It did “work” in a sense. However, I wouldn’t recommend it for nootropic or daily use if you’re healthy. I took 10 drops and felt the effects almost instantly—but they came with a headache that lasted for hours and a racing heart. The product also contains arsenic. The mental clarity and mild energy boost just aren’t worth the side effects and risks. There are dozens of less risky supplements that are just as effective.
Frequently Asked Questions
Why should I expect using Methylene Blue?
Most notice an increase in energy, focus, and mood almost immediately after trying. A sense of well-being is an easy way to explain the feeling! If you don’t get this feeling right away that is okay as well! Some people start to notice effects after a few days or when they increase the amount of drops.
Please note that Meraki does not provide medical advice, and you should consult a qualified healthcare professional with any health, safety, or medical-related questions or decisions.
Is your Methylene Blue safe to use?
Yes. Our Methylene Blue is USP-grade, pharma-certified, and rigorously lab-tested to ensure it contains zero detectable heavy metals, toxins, or fillers. Every batch meets the highest standards of purity and safety, because we believe your health deserves nothing less than Meraki-level quality.
Why do I feel a little run down after my first does?
Some people report feeling off when starting new supplements. If you’re new to Methylene Blue, we recommend starting with a low dose and staying well hydrated. As always, consult your healthcare provider if you have questions about how you’re feeling.

RFK Ultra Blue
Alex M.
Maintaining deep focus while coding used to be a struggle by mid-afternoon. Since adding Ultra Blue to my routine, the mental fog has vanished. I stay sharp and productive through my entire shift without the usual caffeine jitters.
Sarah L
I need consistent energy to lead back-to-back classes, but I hate the 'crash' from typical pre-workouts. This formula provides a clean, steady lift that lasts all day. My endurance feels higher, and my recovery time has noticeably improved.
James P.
Studying for exams requires intense concentration for hours on end. Ultra Blue helps me retain information better and keeps my mind from wandering. It is the most effective tool I have found for cognitive support.
Elena G.
I prioritize mitochondrial health as the foundation of longevity. This pharmaceutical-grade Methylene Blue is the purest I have found on the market. I feel more vibrant, my moods are more stable, and I have a general sense of well-being that I didn't have before.
