I’m purchasing my 6th bottle. This brand is the best I found for size/price and it’s effective. I initiated with a 30 drop dose twice a day for 30 days and now maintain with 2 droppers full (roughly 30-45 drops) daily in juice. I’m 128 pounds. I mix in a dark coffee cup with a metal straw and use it to drink the concoction as well, to bypass my teeth. Although while on vacation I didn’t have the straw and the blue stains disappeared within a few minutes, so I’m not sure the straw method is necessary. Definitely do not put it in a capsule. It needs to coat the throat and all the way down the esophagus to mix with stomach acid to be most effective, which will also ensure the microbiome in the small intestine is not disrupted. Also it’s well absorbed in the mouth and easily crosses the blood brain barrier through the oral mucosa. During my loading period in the first 30 days I noticed a lot of positive changes. Especially with energy, mood and overall better digestion. I had a couple days of stomach cramping and strange poop but compared to everything I had been through, it was minor. And expect periodic blue or green urine. Now feeling energized is my new normal, so I don’t recognize huge improvements anymore. I haven’t missed a daily dose for 7 months so I can’t report the lasting effects after stopping. I battled Lyme and other autoimmune issues for years that I resolved 90% of the way with herbs, ivermectin and fenbendazole. Adding methylene blue was the final step to total freedom. I listened to every podcast and audio book on it that I could find and jumped in with both feet. I only had positive things occur after starting it and have recommended to MANY people that report similar success stories for various health issues. Hopefully this review finds someone that needs to hear it!! I was at my wits end with my health in 2018 and know how devastating it can be when you are trying to heal yourself and mainstream allopathic medicine continues to let you down. Often saying tests are inconclusive and nothing can be done! Or they try to prescribe various pharmaceutical meds to put a bandaid over symptoms instead of treating the root cause - which I refused to take. I’m living proof that something can indeed be done. I have my life back ALL OF IT and will be forever thankful.

It is hilarious to read the bad reviews. Shake the bottle and blue ink all over the walls. If you have all kinds of allergies don't take. Wow. People are so funny. I did my research, bought a book on this stuff and this is my first bottle. Just started my first 10 drops in a big glass of water. The book I just finished reading "The Ultimate Guide to Methylene Blue" recommends taking 10 drops in the morning and 10 at night for the first week no matter your weight. Then the second week 20, and the 3rd week 30. This is what I am going to do. WHen you order this stuff there are no instructions. Do your research. Watch videos. Hope this helps. From what I have read, the doctors sure don't want you to find out about this stuff. NOTE: After taking the first dose an hour ago, I have to say, I do feel something. Very interesting. Almost a warming, calming. You can definitely feel something going on.

I used this product for about two months then stopped for about two months. After not taking it for two months my energy just dropped to almost nothing. Now I started taking it again, I have only used it for a couple of days now but I am already feeling my energy level go up. I would recommend this.

Seems good. I don’t understand why people complain about the taste, it’s a dye not a flavor profile. Either way it does seem to be what it says. I wish they would include verifiable third party testing info. Because you can’t trust anyone anymore. Ultimately it’s worth a try.

I'm going to give this product five stars because I think that the quality is very good and I really like the packaging. As far as effects I think that it may give me more focus. Even if it is a placebo I liked taking two droppers worth. I don't think I will buy again because I'm not sure what I think on the benefits vs the risk. But this product still deserves five stars because of the quality and I think the seller is doing the best they can with what it is.
