Best Methylene Blue Gummies in 2026: 11 Brands Compared

Written by the NooBlue editorial team. We make and sell methylene blue. Every competitor figure below comes from the seller’s own listing, and each listing is linked in the sources at the end so you can check it.

Methylene blue gummies are the easiest way to take a small daily amount of methylene blue. You chew one and you are done, with nothing to measure and no dropper to rinse. The catch is that a gummy fixes your dose, and the category is crowded with marketplace listings that look alike, print “99.9% pure” on the front and say little else. This guide ranks the methylene blue gummies you can buy in the US right now, shows the price, dose and count of each one, and covers four other formats worth a look if a chew does not suit you.

Best methylene blue gummies compared

The table ranks seven gummies first, then four alternatives in other formats. Prices are what each seller’s page showed on September 25, 2026, before shipping and before any bundle discount. Cost per unit is the listed price divided by the listed count.

Prices as of Sep 2026. Marketplace prices change often, so check the seller’s page before you buy. “Cost per unit” is per gummy, capsule, troche or pack as sold. For the drops it is per 5 mg serving of 10 drops.

How to choose a methylene blue gummy

Five checks separate a good gummy from a gamble. Work through them in this order, because the first one rules out the most products.

1. Paperwork on the methylene blue. Methylene blue is also sold as an industrial dye and as an aquarium product, and neither is made for people to swallow. A supplement should name its grade (USP means it is made to the United States Pharmacopeia standard) and show a lab report you can read. Look at what the report covers. An ingredient report tests the raw methylene blue before it goes into the gummy, while a finished product report tests the gummy itself. Few of the gummy brands we checked publish either. Our guide to reading a methylene blue certificate of analysis shows what a real report contains and which details to check.

2. Dose per gummy. The gummies ranked here contain 5 mg to 12 mg of methylene blue each. You cannot split a gummy accurately, so the dose on the label is the smallest dose you can take. If you are new to methylene blue, start at the low end and stay there until you know how you respond. Our guide to how many mg of methylene blue per day explains the amounts people use and why.

3. Count and cost per gummy. Many marketplace gummies come 30 to a bag, so a low sticker price can buy a short supply. Divide the price by the count before you compare. A $19.99 bag of 30 works out to $0.67 a gummy, which is more than a $24.98 bottle of 60 at $0.42.

4. What else is in the chew. Sugar, flavorings and extra actives change what you are taking. Some gummies add vitamin C, CoQ10, NAC or glycine. Check total sugars on the facts panel, and check every added ingredient against anything else you take.

5. Who is actually selling it. On Amazon, one brand name can appear on listings from different manufacturers. Before you buy, check that the seller and the manufacturer match the brand you meant to buy. There is a real example in the where to buy section below.

The 7 best methylene blue gummies, ranked

Our own gummy is first, and we explain why in its section so you can judge the reasons. The other six follow the five checks above, weighted in that order: documentation first, then dose, cost per gummy, other ingredients and seller clarity.

1. NooBlue Methylene Blue Gummies: best overall gummy

NooBlue makes this gummy, and it is our pick. Each Wild Blueberry chew contains 10 mg of USP grade methylene blue and 25 mg of vitamin C (28% of the daily value) in a pectin base sweetened with stevia. The facts panel lists 0 g of total sugars and six calories per gummy. A bottle holds 60 gummies and the label says to chew one a day, so one bottle lasts two months.

What sets it apart from most of the gummies below is the paperwork. Contract Testing Laboratories of America (CTLA) analyzed the methylene blue ingredient, lot 2025022801, in report 135621. The report confirms the ingredient’s identity by HPLC and gives individual results for arsenic, cadmium, mercury and lead. You can read the CTLA report yourself. It has limits, and our product page states them: it covers the methylene blue ingredient rather than every finished batch, and it does not give a numerical purity percentage.

The vitamin C is there for a reason. Vitamin C can donate electrons to methylene blue and turn it into leucomethylene blue, the colorless, reduced form of the same molecule. The gummy looks purple because of its blueberry extract. We have not measured how much of the methylene blue sits in the reduced form inside the finished gummy, and nobody has tested whether that changes absorption, so we make no claim that it does. The mouth is a different matter: NooBlue gummies don’t leave the blue mouth that drops can. The leuco form section below covers the chemistry, and our explainer on what leucomethylene blue is goes further.

A bottle costs $49.99, which is $0.83 a gummy or $0.42 per 5 mg of methylene blue. Two bottles cost $89.98 (10% off), three cost $127.47 (15% off) and five cost $199.96 (20% off), which brings a gummy down to $0.67. Orders of $100 or more ship free worldwide.

Who it suits: anyone who wants one measured chew a day with no sugar, from a brand that publishes a lab report on its methylene blue.

Who should look elsewhere: first timers who want to start below 10 mg (the 5 mg capsule at #8 fits better), and buyers who want the lowest cost per milligram (MaxLife at #4 costs less per milligram, at a higher 12 mg dose).

2. Holistic MD Methylene Blue Gummies: sugar free and vegan for less

Holistic MD’s gummy is listed on Amazon with 7 mg and 14 mg daily dose options, 60 servings per bottle and a blueberry and blackberry flavor. The listing describes the gummies as sugar free and vegan, “3rd Party Certified” and “USP Food Quality”. The product title says “USP Pharma Grade” instead. Those two grade phrases do not mean the same thing, and the listing text does not include or link a lab report, so we could not confirm which one applies.

On September 25, 2026 the listing had no featured offer, and other sellers had it at $25.87, which is $0.43 per serving. That is about half the price of one of our gummies, for a smaller amount of methylene blue per serving. The choice of two daily doses is a genuine plus if you want room to adjust.

Who it suits: buyers who want a sugar free, vegan gummy with two daily dose options and a lower price per serving.

Who should look elsewhere: anyone who wants to read a lab report before buying. The listing mentions certification but does not show the document.

3. TRUEHEALTHIC Methylene Blue Gummies: a 5 mg gummy with a lab result on show

TRUEHEALTHIC sells a 5 mg gummy in bags of 30 from its own store at $29.99, or $1.00 a gummy. The product page describes the methylene blue as USP grade and “99.9% pure”, says it is tested by an outside lab and free of heavy metals, and shows an image of the lab results. A 5 mg dose is a sensible place for a first timer to start, and seeing a result on the brand’s own page is more than the other marketplace gummies in this guide offer.

The weak point is cost. At $1.00 per 5 mg gummy, it is the most expensive gummy per milligram in this ranking, more than double the $0.42 our gummy works out to per 5 mg. A bag also lasts a month at one a day. The brand runs multi-bag offers on its store, so check the current deal before you buy. We compare the two brands side by side in NooBlue vs TrueHealthic, and our TrueHealthic gummies review covers the product on its own.

Who it suits: first timers who want a 5 mg chew and like seeing a lab result on the brand’s page.

Who should look elsewhere: anyone who takes a gummy every day and keeps an eye on cost.

4. MaxLife Naturals Liposomal Pure Methylene Blue Gummies: lowest cost per milligram

MaxLife Naturals lists a 12 mg gummy in a 60 count bottle at $24.98 on Amazon, or $0.42 a gummy. That makes it the lowest cost per milligram of any gummy in this guide. The raspberry flavored chew adds vitamin C ester, NAC and glycine, and the listing says the gummies are made in a GMP certified facility with pharmaceutical grade methylene blue.

Two cautions. First, 12 mg is more than double the 5 mg many people start with, and you cannot halve a gummy accurately. Second, “liposomal” is a claim about how the gummy is made, and the listing gives no data showing that a liposomal structure survives in a chewable or that it changes absorption. The listing text does not describe a lab report on the methylene blue.

Who it suits: experienced users who already know they want about 12 mg a day and want the most methylene blue per dollar.

Who should look elsewhere: beginners, and anyone who would rather leave out the added NAC and glycine.

5. Inditropic Methylene Blue Gummies: a low cost 5 mg trial

The Inditropic listing on Amazon offers 30 blueberry gummies at 5 mg each for $19.99, or $0.67 a gummy, and lists vitamin C among the ingredients. It claims “99.9% pure” methylene blue. The listing text does not describe any lab testing, and it names MCArthur as the manufacturer, so check the seller details before you buy. Our Inditropic methylene blue review compares it with seven other gummies in more depth.

Who it suits: someone who wants to try a 5 mg gummy for a month without spending much.

Who should look elsewhere: buyers who want documentation behind the purity claim.

6. VITALBLOO CrystalBlu Methylene Blue Gummies: vegan, no gluten or soy

CrystalBlu is a 5 mg blueberry gummy sold 30 to a resealable pouch for $19.90 on Amazon, or $0.66 a gummy. The listing says the gummies are vegan and made without gluten, soy or artificial colors. It makes no purity claim and does not describe lab testing, so there is nothing to verify either way.

Who it suits: vegan buyers who want a plain 5 mg chew without gluten or soy.

Who should look elsewhere: anyone who wants to know the grade of the methylene blue they are taking.

7. Marketplace gummies with no lab report: buy with care

Search Amazon for methylene blue gummies and you will find many low cost listings at 5 to 7 mg per gummy, usually 30 to a bag, most of them claiming “99.9% pure”. One example, a ZRLESH 7 mg gummy, was $11.79 for 30 on September 25, 2026, or $0.39 a gummy, and its listing called the gummies vegan and sugar free. The listing text did not name a grade standard or describe any testing.

The low price is real. The problem is that nothing on the page lets you check what you are swallowing. Methylene blue sold for dyeing or for fish tanks is not made to the standard set for people, which is why the grade and a lab report matter more for this ingredient than for most supplements. If you buy a marketplace gummy, pick one whose listing links a current lab report for the methylene blue, and read our guide to what methylene blue purity claims mean first.

Who it suits: buyers who put price first and find a listing that links a current lab report.

Who should look elsewhere: anyone who cannot find that report. Spend a little more on a brand that shows one.

Not sold on gummies? Four alternatives

A gummy is a fixed dose in a sweet chew. If you want a smaller dose, finer control or no chew at all, one of these formats fits better. We rank each format in more depth in our guides to the best methylene blue capsules, the best methylene blue drops and the best methylene blue troches.

8. NooBlue Methylene Blue Capsules: the 5 mg starting point

NooBlue makes these. Each vegetable capsule holds 5 mg of USP grade methylene blue and 10 mg of vitamin C, with rice flour as the only other ingredient inside a cellulose shell. There are 60 capsules per bottle, taken one a day with food, and a bottle costs $37.99, or $0.63 a capsule. The same CTLA ingredient report covers the methylene blue.

The capsule is the cleanest way to start at 5 mg, half the dose of our gummy, with no flavor and no sweetener. What you give up is the chew. If you like a gummy as part of your morning, a capsule will feel like a pill, because it is one. Our methylene blue gummies vs capsules comparison goes through the differences in detail.

Who it suits: first timers and anyone who wants exactly 5 mg. Who should look elsewhere: people who dislike swallowing capsules.

9. NooBlue Methylene Blue Drops: adjustable dosing

NooBlue makes these too. The 50 mL bottle holds a 1% solution of USP grade methylene blue in distilled water, which works out to 0.5 mg per drop, 5 mg per 10 drops and 10 mg per full dropper. At $29.99 for about 100 servings of 5 mg, a serving costs $0.30, the lowest cost per dose of any NooBlue format.

Drops give you the finest control of any format, in 0.5 mg steps. They also stain skin, fabric and counters, and you have to count drops into water or juice every day. Our gummies vs liquid guide weighs up the two.

Who it suits: people who want to adjust their dose in small steps, and anyone who wants the lowest cost per dose. Who should look elsewhere: anyone who wants a quick routine with nothing to measure.

10. Troscriptions Just Blue: a troche you can quarter

Just Blue is a troche, a lozenge that dissolves in the mouth, rather than a gummy. Each one contains 16 mg of methylene blue and is scored so you can break it into quarters of about 4 mg. Troscriptions sells a pack of 4 troches for $27.00 on its own store, which is $6.75 a troche or about $1.69 a quarter. The brand says its products are tested by an outside lab, USP grade and made in a cGMP certified facility.

Be ready for color. The brand’s own FAQ says the troche will turn your mouth blue when used as directed, and that the discoloration can last from 2 to 24 hours. Per milligram it also costs more than any gummy in this guide.

Who it suits: people who want a troche and like splitting a dose into quarters. Who should look elsewhere: anyone who minds a blue mouth.

11. MitoZen Lumetol Blue Bars+: high dose bars for experienced users

MitoZen’s Lumetol Blue Bars come in 40 mg and 180 mg versions. On the brand’s store, a pack of the 40 mg bars costs $89.95 and a pack of the 180 mg bars costs $179.95. The suggested serving for the 40 mg bar is a quarter of a bar up to a full bar, about 10 mg to 40 mg of methylene blue. Each bar adds vitamin C with phycocyanin, curcumin, quercetin, riboflavin, EGCG and lutein. The brand says the bars are not troches: you place one at the back of the mouth and wash it down with a drink to avoid blue staining.

This is a product for people who already know how they respond to methylene blue and want a much higher dose than any gummy. The brand’s page does not state how many bars come in a pack, so we could not work out a cost per bar.

Who it suits: experienced users who want a high dose with added plant compounds. Who should look elsewhere: beginners and anyone on a budget.

What the research says about methylene blue, and what it does not

Methylene blue interests researchers because of how it behaves inside mitochondria, the parts of cells that make energy. It can accept electrons and pass them on, cycling between its blue oxidized form and its colorless reduced form, leucomethylene blue. Here is what the main studies found, and where their limits are.

Human brain imaging. In a randomized trial at the University of Texas, 26 healthy adults aged 22 to 62 had brain scans before and one hour after a single oral dose of methylene blue or a placebo. Neither the participants nor the researchers knew who got which. Methylene blue increased activity in brain regions used for sustained attention and short term memory, and it was linked to a 7% increase in correct answers during memory retrieval (Rodriguez et al., Radiology, 2016). A second paper from the same group found stronger resting connectivity between brain regions involved in perception and memory (Rodriguez et al., Brain Imaging and Behavior, 2017).

The dose gap. The single dose in that trial was 280 mg of USP grade methylene blue, about 4 mg per kilogram for a 70 kg adult, given to 13 of the 26 participants (full text). That is 28 times the methylene blue in one of our gummies, and 56 times a 5 mg gummy. No published study has tested a daily gummy for memory, focus or energy. So when a gummy brand, us included, cites these trials, read them as evidence about methylene blue at a far higher single dose. They tell you nothing direct about a 10 mg chew taken every morning.

Cell studies. In human fibroblasts, a type of connective tissue cell, grown in the lab, very low concentrations of methylene blue raised the activity of mitochondrial complex IV by 30% and increased the cells’ oxygen use by 37 to 70% (Atamna et al., FASEB Journal, 2008). The same paper describes how enzymes inside cells reduce methylene blue to leucomethylene blue and how cytochrome c turns it back again. These are results in cell culture. They show a mechanism. They do not show that a supplement does the same thing in a person.

Why more is not better. A review by Rojas, Bruchey and Gonzalez-Lima describes methylene blue as having a hormetic dose response, meaning opposite effects at low and high doses (Rojas et al., Progress in Neurobiology, 2012). The Radiology paper describes 0.5 to 4 mg per kilogram as the low dose range in which methylene blue improved memory in animal and human studies, with opposite effects above 10 mg per kilogram. Hormesis is a good reason not to stack gummies in search of a bigger effect. It is not evidence that small gummy doses work.

For a plain summary of what each claimed benefit rests on, read our evidence audit of methylene blue gummy benefits, and our look at whether methylene blue gummies are effective.

Does the leuco form matter?

Most gummies in this guide contain methylene blue in its usual oxidized, blue form. Our gummy pairs it with vitamin C. In lab experiments run in a solvent, ascorbic acid (vitamin C) reduces methylene blue to its colorless form, while oxygen dissolved in the solution pushes the reaction back the other way (Hallock et al., Journal of the American Chemical Society, 2003). That back reaction matters. Leucomethylene blue does not stay reduced forever once air gets to it.

What this means for you is limited, and we would rather say so plainly. We have not measured the share of reduced methylene blue in the finished gummy, how that share holds up over the shelf life, or whether it changes how much you absorb. The vitamin C pairing has known chemistry behind it. Whether it makes a difference once you have swallowed the gummy is untested. One part you can see: our gummies don’t turn the tongue blue the way drops can. Our methylene blue gummies ingredients guide goes through everything else that goes into a typical chew.

Where to buy methylene blue gummies

You can buy methylene blue gummies from brand websites and from Amazon. Stock in pharmacies and health food stores varies a lot, as our guide to finding methylene blue in stores and pharmacies explains.

Buying from the brand’s own site gets you the brand’s return policy and a direct line if something is wrong. NooBlue ships worldwide from nooblue.com, free on orders of $100 or more, with 30-day returns and dispatch in 1 to 2 business days with tracking. You can see all three formats side by side in the NooBlue shop.

On Amazon, check who you are buying from. One example: a 5 mg, 30 count listing titled “Feelific Methylene Blue Gummies” names TRUEHEALTHIC as the brand and SolarVine as the manufacturer, while TRUEHEALTHIC also sells its own 5 mg gummies on its store. We do not know how the two are related, but the example shows why the seller and manufacturer fields are worth a look. If they do not match the brand on the label, buy direct from the brand.

Side effects and who should not take methylene blue gummies

At gummy doses, the effect people notice first is harmless but startling. Methylene blue is a dye that passes into urine, so urine can turn blue or green for a while after a dose. The prescribing information for the injectable form notes that it can interfere with urine tests that rely on a blue indicator, so tell your doctor you take it if you are due a urine test (prescribing information, DailyMed).

The serious risk is an interaction. Methylene blue is a potent, reversible inhibitor of MAO-A, the enzyme that breaks down serotonin (Ramsay et al., British Journal of Pharmacology, 2007). Combined with medicines that raise serotonin, it can cause serotonin syndrome, which can be life threatening. A systematic review found 26 patients who developed acute confusion after methylene blue infusions, and 24 of them were taking a serotonin reuptake inhibitor (Ng and Cameron, Psychosomatics, 2010). Those were hospital doses given into a vein, far above a gummy, but the mechanism does not depend on the format.

How we compared these products

We read each product’s own page on September 25, 2026: the brand’s store where it sells direct, otherwise the Amazon listing. Prices, counts, doses and claims in this guide come from those pages, and cost per unit is our own arithmetic from the listed price and count. We did not buy competitor products or send them to a lab. We also left review counts out of the ranking, because they are easy to inflate and say nothing about the grade of the methylene blue.

We ranked on five checks, weighted in this order: documentation of the methylene blue, dose per unit, cost per unit and count, other ingredients, and how clearly the seller is identified. NooBlue makes the products ranked #1, #8 and #9. Our gummy sits at #1 because it is the gummy we make and recommend, and its section sets out the reasons so you can weigh them yourself.

Two gummies from earlier versions of this guide are out. Lunakai’s 20 mg gummy with 40 mg of CoQ10 and 20 mg of vitamin C showed as sold out on the brand’s store, and its Amazon listing no longer loads. We also dropped a Thinbi gummy because we could not find one on sale. We will look at both again if they come back.

Frequently asked questions about methylene blue gummies

What are the best methylene blue gummies?

NooBlue Methylene Blue Gummies are our pick: 10 mg of USP grade methylene blue with 25 mg of vitamin C, 0 g of sugar, 60 gummies per bottle and a published lab report on the methylene blue ingredient, at $0.83 a gummy. NooBlue makes them. If you want a 5 mg gummy, TRUEHEALTHIC shows a lab result on its store page but costs $1.00 a gummy, and MaxLife Naturals has the lowest cost per milligram at 12 mg a gummy.

What is the best methylene blue on the market?

The best methylene blue for you depends on the format you will actually take. NooBlue gummies suit a daily chew, NooBlue’s 5 mg capsules suit a precise start, and NooBlue’s 1% drops suit adjustable dosing at $0.30 per 5 mg serving. Whatever the brand, look for USP grade methylene blue and a lab report you can read. Our guide to the best methylene blue supplements compares brands across every format, and our list of top methylene blue brands looks at the companies behind them.

What not to mix with methylene blue?

Do not mix methylene blue with SSRIs, SNRIs, MAOIs, tricyclic medicines with serotonin activity, or opioids such as tramadol. Also avoid serotonergic supplements such as 5-HTP, L-tryptophan and St. John’s Wort. Methylene blue blocks MAO-A, the enzyme that breaks down serotonin, and the combination can cause serotonin syndrome. Ask your doctor or pharmacist before combining it with any prescription medicine. Our methylene blue interactions reference lists more medicines by class.

What brand of methylene blue do hospitals use?

Hospitals use prescription methylene blue injection, given into a vein by clinicians. In the US the branded version is ProvayBlue, and a generic methylene blue injection is also sold. These are medicines for specific hospital uses, dosed by body weight and given under monitoring. They are not supplements, and no gummy is a substitute for them.

Why don’t doctors recommend methylene blue?

Many doctors are cautious about methylene blue as a supplement for three reasons. The human evidence for everyday use is thin, because the best known trials gave one dose far higher than a gummy and measured brain scans rather than long term results. It interacts dangerously with common medicines that raise serotonin. It is also unsafe for people with G6PD deficiency, which a blood test can check for. If you want to try it, talk to your doctor first, especially if you take any medicine.

Where can I buy methylene blue gummies?

From brand websites and from Amazon. NooBlue sells its gummies at nooblue.com with free worldwide shipping on orders of $100 or more and 30-day returns. On Amazon, check that the seller and the manufacturer match the brand on the label, because some listings reuse brand names.

How many milligrams are in a methylene blue gummy?

The gummies in this guide contain 5 mg to 12 mg each. TRUEHEALTHIC, Inditropic and CrystalBlu use 5 mg, Holistic MD lists 7 mg and 14 mg daily doses, NooBlue uses 10 mg and MaxLife uses 12 mg. Lunakai’s gummy, now sold out, had 20 mg. You cannot split a gummy accurately, so if you want to start below 10 mg, a 5 mg capsule or a measured dose of 1% drops is the simpler route.

Do methylene blue gummies really work?

A gummy delivers the same methylene blue as a capsule or drops. What nobody knows yet is whether 5 to 12 mg a day does anything measurable for focus or memory, because the human trials used a single 280 mg dose and no trial has tested a daily gummy. If you try one, keep the dose low, give it a few weeks and judge the result honestly. Our methylene blue gummies review audits the lab reports of eight brands.

Are methylene blue gummies as good as capsules?

They deliver the same compound, so the real question is format. Capsules give an exact 5 mg with no sweetener and no flavor. Gummies are easier to take every day and come in larger doses, 10 mg in our case. Choose the capsule to start low and the gummy once you know 10 mg suits you. Our explainer on what methylene blue gummies are covers the format from scratch.

Can I take methylene blue gummies every day?

Our gummies are labeled for one a day. Long term daily use at gummy doses has not been studied in trials, so check with your doctor if you plan to take methylene blue for months, and stop if you notice side effects. Our guide on how to take methylene blue gummies covers timing, food and missed doses.

Can methylene blue gummies help with neuropathy?

No gummy in this guide has been studied for nerve pain or neuropathy, and none should be used in place of care from your doctor. Some listings on Amazon and on brand stores use the word in product names. A product name is a marketing choice and tells you nothing about evidence. If you are managing a diagnosed condition, talk to your doctor before taking methylene blue, especially if you take medicines for nerve pain, because some of them act on serotonin.

Can I take methylene blue gummies at night?

We suggest the morning. Many of our customers take methylene blue in the morning or early afternoon, and some people find it mildly stimulating, so a late dose may get in the way of sleep. A gummy with breakfast is the simplest routine to remember.

The verdict

For a daily methylene blue gummy, buy NooBlue Methylene Blue Gummies: 10 mg of USP grade methylene blue with 25 mg of vitamin C, no sugar, two months per bottle and a lab report on the methylene blue that you can read for yourself. If you are new to methylene blue and want to start at 5 mg, begin with the NooBlue capsules and move to the gummy once you know how you respond. If you want the finest control and the lowest cost per dose, the 1% methylene blue drops cost $0.30 per 5 mg. Whichever you choose, check your medicines first and start low.
