Methylene Blue Pharmaceutical Grade 2oz– USP Grade 1% Solution with Balanced Electrolyte SolutionThird-Party Tested Brain Health Supplement for Humans –No Formaldehyde High Cognitive Support

I've been taking this for about a week and am already feeling sharper and more focused. It tastes a bit metallic but I add it to juice and it's fine. Really easy to add to a water bottle before work to have ready at my desk. I also seem less tired during the 3pm slump at work so that's a positive. It's very blue and will stain your tongue but it's worth it for the benefits. I'll keep this as a part of my wellness routine.

I’ve been using Thinbi Methylene Blue Drops for a few weeks, and the results are impressive. My mental fog has lifted, and I feel more energized throughout the day. The drops are easy to use, and I appreciate that they’re third-party tested for quality. Yes, it turns your tongue a bit blue, but that’s a small price for the benefits. Highly recommend for anyone looking to boost their cognitive function and energy levels naturally.

It is blue! Can say I was let down that the dropper is not graduated so you can get a precise amount of product.

Very high-quality product, but it’s important to consult your doctor before starting.Especially if you have chronic conditions or are taking other medications.The product arrived well-packaged. The solution is clear, with a rich blue color, and easy to dose.I chose this brand specifically because of the USP Grade indication and the absence of formaldehyde. It’s also nice that the formula includes balanced electrolytes.After starting carefully with microdoses, I noticed a slight improvement in concentration and mental clarity.A good supplement that I use as part of a broader approach to supporting cognitive health.

I’ve been using Methylene Blue 1% Solution as part of my wellness routine, and so far, it’s been a really interesting addition. The flavor is slightly bitter and metallic, but not overwhelming—definitely manageable if diluted or taken with juice. The texture is smooth and liquid, easy to measure and use. I started using it after hearing about its cognitive support benefits, and I’ve noticed a slight boost in mental clarity and energy. I’d recommend starting with a low dose and doing your own research, but overall, it’s a solid product if you’re curious about nootropic or mitochondrial support. Just be aware—it will stain everything blue, so handle with care!

I've only used this a few times and it does give you energy but, I do not like the blue-ing of the mouth. It creeps me out. I'm going to try this in pill form.

Highly recommend if you're looking for a pure, reliable methylene blue supplement!I've noticed better focus and energy since I started using this methylene blue. The quality is excellent, and I love that it's free from harmful additives.Super easy to use and definitely worth it!

This methylene blue is high quality and arrived just as described. I like that it’s pharmaceutical grade and doesn’t have any weird smell or additives. I’ve been using it for a short time and already feel more focused and clear-headed. Definitely a good product for brain support.
