Methylene Blue Pharmaceutical Grade, USP Grade, Third-Party Tested Brain Health Dietary Supplement for Humans, No Formaldehyde, Made in USA (0.5% 50ml Bottle)

Great item and it also improved my focus and my sleep quality.

Great product gets me going at the beginning of my day. Re-ordered thrice same effect!

This is an amazing product. Great value for the money, and effective as well as easy to use... Just add a few drops to water or juice... great for sleep and minor pain relief. Just be sure to keep the doses small and don't take this if you are on any form of SSRI's. Most people should consult a doctor before taking this, or take it while under the care of a physician familiar with this product. It will make you pee blue, and it will permanently stain anything it touches, so handle with Care.

Pretty good product. Noticed a difference on day two. Staying around 5 drops daily. I do three drops in a medium glass of water then hour later do two more. It does taste nasty which is why I split my dose. Be careful it will permanently stain fabric and some surfaces. Noticed a clearer head and less fatigue.

This stuff is UNBELIEVABLE!!look it up and do the research! This is one of the most recommended brands and it's SO POWERFUL..JUST tryUPDATE, after 30 days or more use i notice my skin tighten up! Not just a little! But DRAMATIC took ten years off my age look!!Crows feet and such GONE!!This is hands down the most powerful supplement I've ever used!!I've never had something have so many benefits but no backfire! The ONLY thing I've found is if I take too much I get a slight headache, so I don't take to much (5mg, once or twice/daily)I tried another brand as well and came running back here!

The product is as described and arrived undamaged. It did take 3 days longer to get here than originally expected when we purchased it on Amazon. The product is tasteless and mixes easily with juice or water.

I’ve just taken it a couple of times. Not really how I’m supposed to do this. I just got them because my daughter said they were good for anxiousness. Haven’t taken it enough to see if that’s correct. Be careful though. It’s like blue dye and will stain whatever it gets on

It's only been one day, but I already noticed an improvement. I took it last night before bed (sucked through a straw at the back of my tongue to minimize blue mouth and teeth), and I woke up with MUCH LESS morning grogginess. I felt clear-thinking and had no problems staying focused at work, despite having only 5 hours of sleep. I didn't expect any results this soon, so today was a very pleasant surprise (as was the green pee in the toilet).
