Methylene Blue 1% Compass Laboratory | USP-Grade Methylthioninium Chloride Liquid | High Purity Dietary Supplement for Brain Function & Cognitive Health | No Formaldehyde 237ml Glass Bottle

ok let's talk about the taste. The one's your referring to that taste better are garbage. they don't work. Compass is hands down the best. I've been talking this for a few years on and off. I've tried several only compass is made right. The one's that taste good are scamming you. just fyi

I've been taking the specific brand of methylene blue for a few months now on and off. I was impressed that Walmart carried this item and I could get it shipped and delivered to my house relatively quickly. I will definitely purchase again in the future. This needs to be diluted in water or another liquid and can cause staining in your mouth and teeth so good they're all rinse afterward is needed, but that is the case with all methylene blue products.

Been taking it for a week now. its too soon to say if its working. But i do feel like its working. I would mix it with something other than water. there is a slight aftertaste when used with water, but not noticeable when mixed with anything else.

I needed to refill my OTC supplement that my usual source was out of. Surprisingly they had it cheaper, so I bought two.

This is a life changing product. I was initially skeptical of MB, but will continue to use it. DO YOUR RESEARCH related to dosing etc. I do 6-8 drops twice a day (after breakfast and lunch) in water and it works great. Speaking from my own anecdotal experience here, but my eye issues have almost completely resolved. I feel mentally sharper and myself again. I've dealt with significant brain fog, anxiety, and numerous other things since Dec 2021 and I can confidently say that nothing I've tried has helped as much as MB. I did notice that my hands and feet would get cold. Likely due to the vasoconstriction effect this has, I've offset it by supplementing with nitric oxide booster that contains L-Argentine, L-Citruline, etc.

tested it and its pure blue meth not fake like some others I wasted money on

Drink thru a straw to not have blue teeth. Feeling better everyday

This methylene Blue is great for your health!! We have used it for several months and have noticed a significant energy boost. We highly recommend!!

Had purchased this exact brand and dosage prior. Had no issues with it. Reordered and received a different style bottle with a duller, generic looking label. Figured they had switched suppliers for their bottling and labeling, but I was suspicious. After taking identical doses for a week, there has been no discoloration of urine whatsoever. With the previous bottle, a mere 10 drops would cause an immediate change of urine to blue, a telltale sign that it's genuine methylene blue. Walmart needs stricter controls over its third-party suppliers, cause whatever this stuff is, it's not methylene blue.

My doctor says that its not reliable.
