DO NOT use the aquarium fish medicine version! - Last year, I "retired". I was not feeling so good health wise. I had very little energy and was somewhat depressed. In desperation, I went on a diet and cut out sugar and bread and, and, and..... One day, I watched a long video online about methylene blue and I made up my mind to try it. There are quite a few books out there about it and I read through a couple of them. I began just taking 20 drops per day and got up to 80. I began to really feel better! And I ALSO felt less depressed and I had some memories returned to my brain! I had a very healthy summer. I think people thought I was crazy when I told them about this stuff, but they could see a difference in my personality and my skin. Anyway, for some reason, I stopped taking it about 3 months ago and my health declined again! So, I ordered this bottle because it's a really good deal $$ wise! Since slowly increasing my dosage back to what I had been at 3 months ago, I have suddenly I begun to feel more alive again all of the sudden! I'm even more convinced that this stuff WORKS healing helps in many systems of the human body! I can't tell you what part of my body is utilizing it, but it IS utilizing it somewhere or other! I didn't experience much pain relief because I wasn't experiencing any pain at the time but somehow, I believe I experienced some emotional pain relief. I prayed a lot during that time, so I have to give the LORD the credit...I have definitely heard anecdotal stories of other people who HAVE experienced levels of pain relief using MB. That being said, I want to say that the bottle arrived quickly and packaged neatly and had no leaks or tears. The bottle is sealed well with a plastic seal surrounding the dropper top to keep it on tightly. It's not difficult to use. All you need to do is pour about 6 oz of juice into a glass and add the number of drops you need into the glass with the juice. Give it a big of a swish or a stir and just drink it down. The reason I suggest using juice is because it will help lend a better taste to it. You DO NOT want to put these drops directly into your mouth because it will stain your tongue blue for a few hours. If you dilute it with juice, you can quickly swallow it down and it has a noticeably milder flavor, otherwise it tastes somewhat medicinal. If you wear dentures, I would also suggest taking them out before you drink this because you will need to really scrub your dentures! As far as dosage goes, you will need to do some research because dosage goes by your weight. I am not a doctor so I will not suggest a dosage to you. Each person is different and has to figure out their dosage by themselves or with a doctor. The only thing I WILL TELL YOU is that under NO CIRCUMSTANCES should you consume this supplement if you are taking any kind of medication for regulating your SEROTONIN LEVELS! You absolutely must talk to your doctor about this. Combining this supplement with an SSRI (selective seratonin reuptake inhibitor) can cause you to experience something commonly called SERATONIN SYNDROME which can be life threatening. I do not take any other medications, so I don't have to worry about it. Your doctor knows what methylene blue is since it has been used in hospitals and clinics for over 100 years, yet it is not considered a prescription drug and is a legal supplement in every state. It is also important that you DO NOT use this same chemical from an aquarium supply vendor since it is commonly used to heal many tropical fish5 ailments. The problem with using that version is that it isn't PURIFIED like the methylene blue with the label stating 1% USP PHARMACEUTICAL GRADE! This grade for human usage is third party tested for contaminants such as heavy metals that can harm you. The product that is sold in aquarium supply pages is NOT TESTED for poisonous substances such as heavy metals, arsenic, etc. and IS CONSIDERED DANGEROUS FOR PEOPLE, so DO NOT risk it. The quality of this product offered IS pure and high quality. You are not a fish! Review: Methylene blue - This is my go-to company for this. I feel this one more than others.

I feel this one more than others. Great clean feeling energy, love this stuff. ### ⭐⭐⭐⭐⭐ Ummm excuse me. Where has this been all my life! *by M***0 on December 19, 2025* THIS IS WHAT I HAVE BEEN MISSING!! I take Life Extension brand NAD, Glutathione, Two Per Day (multivitamin) and Omegas. I have not been eating the best as it is around the holidays and I have not been getting my 10,000 steps so my mental state and "want to" has been not great. I am on day 5 of this and it is a mental game changer. I started with 5 drops the first few days. I didn't feel a noticeable difference but I was getting more done around the house and thinking much clearer and focused at work. Even though I was not actively thinking of what needed to be done, I was checking off what needed to be done. On day 3 I tried 10 drops. I take if first thing in the morning with my NAD and glutathione on an empty stomach. I mix it with about 6 ounces of Simply Lemonade and mix with a frother. I store in the fridge. I am hooked. I would definitely recommend start with 5 drops and increase accordingly. 10 drops I feel very much like my brain is ignited. Kind of like a caffeine effect but so very clean and no jitters. I feel more of a sense of happiness as well. Like I am "lighter" in a mental way. This product is very easy to use. The color doesn't stain my tongue as I mix with the 6 oz and drink fast, all before brushing teeth. My co-worker and I tease that we need a "happy pill" that is all natural. I think this is it for me. Highly recommend you do your research and add this to your routine if you are medically able. I think I will try 8 days on a regular day and 10 drops if I am going to be more active. ## Frequently Bought Together - Methylene Blue 1% Solution 3.4 Fl Oz - 100 ml | Ultra High Purity | USP Pharma Grade Ingredients - Third-Party Tested | Formaldehyde Free | Glass Bottle | Heiltropfen® - L Methyl Folate 15mg Plus Methyl B12 Cofactor – Organic Berry Flavor, High Potency Liquid Sublingual Active 5-MTHF Form - Supports Mood, Methylation, Cognition – Bioactive Forms Vitamin B9 & B12 (1oz) - 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 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/670596327-methylene-blue-1-solution-3-4-fl-oz-100-ml](https://www.desertcart.at/products/670596327-methylene-blue-1-solution-3-4-fl-oz-100-ml) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-03*
