Top Methylene Blue Brands in 2026: 8 Brands Compared

Published: August 8, 2026 · Last updated: August 12, 2026 · By NooBlue Editorial · 8 brands compared · All prices checked on August 8, 2026

If you are trying to work out which of the top methylene blue brands is worth your money, the honest answer is that the category is harder to shop than it looks. Eight brands dominate the search results, they price in four different units, half of them do not state a milligram dose anywhere a buyer can find it, and almost every one of them describes itself as “USP grade” and “third-party tested.” This guide compares those eight brands on the things that actually differ — unit dose, cost normalised to a single common unit, format, and how much of the quality claim we could independently confirm at publish time.

One thing sets this comparison apart: we tell you what we could not verify. Where a price, dose, or certificate could not be confirmed on August 8, 2026, the row says so rather than carrying a number forward from an older article — which is why some cells below are deliberately blank.

Top Methylene Blue Brands at a Glance

Every price below was read at publish time on August 8, 2026, and every cost figure is normalised to the same unit — US dollars per 5 mg of methylene blue — so the rows are actually comparable. Brands sell in capsules of 5, 10, 12 and 16 mg, in millilitres of 1% solution, and in gummies, which makes headline prices almost meaningless on their own. Where we could not confirm a current price or a stated dose, the cell says “not verified at publish time” and no cost figure is shown.

Cost per dose in that table is normalised to a 5 mg serving, so brands sold at 10 mg, 12 mg or 16 mg per unit can be compared on the same basis rather than on sticker price. Two figures are worth pausing on. First, NooBlue’s liquid at $0.30 per 5 mg is the cheapest verified liquid in the comparison by a wide margin — Meraki Blu, the best-known liquid brand, costs almost four times as much for the same amount of methylene blue. Second, Nutricel genuinely beats NooBlue on cost per milligram in capsule form, and we have ranked it second rather than burying it. If raw cost per milligram is your only criterion, buy the Nutricel. Most buyers have a second criterion, which is where the ranking below comes from. For the wider category view, see our full methylene blue supplement rankings, and if you want to understand the grading language every one of these brands uses, what 99% USP purity actually means is the place to start.

How We Evaluated These Methylene Blue Brands: Our Methodology

We did not test these methylene blue brands in a laboratory and we are not going to pretend otherwise. What follows is a documentation and pricing comparison, built from each brand’s own public listings read on August 8, 2026. The weighting:

• Purity grade (40%) — USP grade ranks above unspecified “pharmaceutical grade,” which ranks above lab grade, which ranks above food grade, which ranks above undisclosed. The gap between USP and “lab grade” matters because lab-grade dye is not manufactured to a purity specification intended for human consumption.
• Third-party testing and COA availability (20%) — does the brand publish a Certificate of Analysis, and can a buyer actually reach it?
• Cost per 5 mg (20%) — normalised across capsules, troches and liquid so the numbers mean something.
• Reputation and review depth (10%) — how much independent buyer feedback exists.
• Format and convenience (10%) — capsule, liquid, troche or gummy, and how precisely a buyer can control the dose.

Dose granularity deserves a note, because it is where the brands diverge most and is barely discussed elsewhere. A 5 mg capsule lets a person take 5, 10 or 15 mg. A 16 mg troche does not divide neatly into anything. If you are new to the compound, the smallest unit a brand sells matters more than the price on the bottle. Our guide on how to choose a methylene blue supplement goes deeper, and what methylene blue should cost in 2026 covers pricing.

#1. NooBlue — Best Overall Among the Top Methylene Blue Brands

NooBlue takes the top position for a specific and checkable reason: it is the only brand in this comparison that sells both a 5 mg USP-grade capsule and a 1% liquid, with third-party batch testing behind both. That combination matters because it lets a buyer start at the smallest unit dose available in this category and move to a liquid later if they want finer control, without changing brands or re-learning a label.

Key specs. The capsules are $37.99 for 60 capsules at 5 mg each, with vitamin C included, in vegetable-cellulose capsules. The label’s suggested use is one capsule daily with food, so one capsule equals one serving and a bottle is a two-month supply — $0.63 per serving. The liquid is $29.99 for 50 ml of 1% solution, which is 500 mg of methylene blue in the bottle, working out to $0.30 per 5 mg equivalent. Both are stated as USP grade at 99.9%+ purity, third-party tested for heavy metals, and produced in a GMP-certified facility.

Pros: The 5 mg capsule is the smallest per-capsule dose of any brand here, which makes it the most controllable option for someone who wants to start low. The liquid is the cheapest verified liquid in the comparison at $0.30 per 5 mg. A batch Certificate of Analysis is published rather than merely referenced. Free worldwide shipping applies over $100, and the range ships to the UK and Europe with GBP and EUR converted at checkout — which matters, because UK buyers otherwise face a thin domestic market, as our buying guide for UK readers lays out.

Cons: NooBlue is a smaller brand than Troscriptions or Meraki and carries fewer third-party marketplace reviews, so buyers who weight review volume heavily will find less to read. The capsules are not the cheapest per milligram — Nutricel is, at less than half the cost per 5 mg — because a 5 mg unit costs more to produce per milligram than a 12 mg one. And there is no buccal or sublingual option in the range at all. If you want a troche, NooBlue does not make one. For a sceptical outside look at the brand, we have also published an independent assessment of whether NooBlue is legit.

Best for. Anyone who wants the smallest available unit dose, wants both a capsule and a liquid option from one brand, or wants the lowest verified cost per milligram in liquid form.

#2. Nutricel — Best Price Per Milligram

Nutricel is the value winner of this comparison and we are not going to soften that. Its Blue Boost capsules are listed at $34.90 for 60 capsules at 12 mg each, which is $0.24 per 5 mg equivalent — less than half NooBlue’s capsule cost on the same normalised basis. The brand states USP grade, includes vitamin C ester for absorption, uses organic cacao powder as an excipient, and describes Eurofins third-party testing and an NSF-certified manufacturing facility.

Key specs. 12 mg per capsule, 60 capsules, $34.90 direct from the brand at publish time. The same product appears at $29.99 on Walmart and $35.00 on Amazon, so the real-world price band is roughly $26–$35 depending on where you buy and which formulation you pick — there is also a 50-capsule version blended with mushroom extracts at $33.90.

Where we read the specs: Nutricel’s own Blue Boost product page.

Pros: The cheapest verified cost per milligram in the comparison. Genuine third-party testing detail, named to a specific laboratory rather than left vague. Wide retail distribution, so it is easy to buy and easy to return.

Cons: The 12 mg unit dose is the practical catch. There is no way to take less than 12 mg from a 12 mg capsule, which removes the option to start low and build up — the standard advice for anyone new to this compound. Pricing also varies by more than 30% across retailers for what appears to be the same product, which makes it harder to tell if any single listing is actually a good deal on the day you buy. Nutricel has additionally published pages comparing itself directly against NooBlue by name; we have written our own head-to-head Nutricel comparison so readers can see both sides rather than only the vendor’s framing.

Best for. Experienced users who already know they want a dose in the 12 mg range and want the lowest cost per milligram available.

#3. Troscriptions Just Blue — Best Buccal Format

Troscriptions is the most established name in this category and the only brand here built around a buccal troche rather than a swallowed capsule. Just Blue delivers 16 mg per troche in a lozenge placed between the upper cheek and gum, dissolving over 15 to 30 minutes and absorbing through the oral mucosa rather than the gut.

Key specs. 16 mg per troche, described by the brand as pharmaceutical-grade and purity- and potency-tested. Price not verified at publish time — retailer listings we checked disagreed materially on pack size and per-unit cost, and rather than publish a figure we could not stand behind, we have left the cost cell empty. We would rather show you a gap than a wrong number.

Where we read the specs: the Troscriptions Just Blue product page.

Pros: The buccal route genuinely differs from a capsule and some people prefer it. Troscriptions has the longest track record of any brand here, and is widely stocked through practitioner and clinic channels — its own kind of vetting.

Cons: It is consistently the most expensive option per milligram in this category, and the 16 mg unit is the least divisible dose here — a troche does not split cleanly, so dose control is coarse. The 15-to-30-minute dissolve time is also a real commitment compared with swallowing a capsule. Our full Troscriptions review covers the format trade-off in more depth.

Best for. Buyers who specifically want a buccal or sublingual product and are willing to pay a premium for it.

#4. LVLUP Health Mito Blue — Best All-in-One Mitochondrial Stack

LVLUP Health takes a different approach: rather than sell methylene blue alone, Mito Blue combines 10 mg of USP 99% methylene blue with acetyl-L-carnitine, ubiquinol and PQQ in one capsule, at a stated $1.65 per serving. Normalised to methylene blue content alone, that is $0.83 per 5 mg — but that comparison is unfair to the product, because you are also buying three other ingredients.

Key specs. 10 mg methylene blue at USP 99% purity, plus ALCAR, ubiquinol and PQQ, $1.65 per serving.

Where we read the specs: the LVLUP Health Mito Blue product page.

Pros: If you were going to buy CoQ10 or PQQ separately anyway, the combined price is competitive and the convenience is real. The cofactor selection is coherent rather than a random kitchen-sink blend.

Cons: Combination products remove your ability to adjust one variable at a time. If you react to Mito Blue, you cannot tell which of four ingredients caused it, and if you want more methylene blue you must also take more of everything else. The 10 mg unit again rules out starting lower. It is also the most expensive capsule per milligram of methylene blue in the comparison. We have set out the trade-off in detail in LVLUP Mito Blue measured against NooBlue.

Best for. Buyers who want a single capsule covering several mitochondrial-support ingredients and do not need to isolate variables.

#5. Meraki Medicinal Meraki Blu — Best Brand Recognition in Liquid

Meraki Medicinal is probably the most visible methylene blue brand in US search results, and its Meraki Blu liquid carries thousands of marketplace ratings. It is also, on the numbers, the most expensive liquid in this comparison by a considerable margin.

Key specs. 150 mg of methylene blue in a 30 ml bottle — 5 mg per millilitre — at $35.00 observed on August 8, 2026. That is $1.17 per 5 mg equivalent. The brand states USP grade, 99.99% purity, per-batch heavy-metal testing, and US manufacturing. The dropper is calibrated at roughly 0.25 mg per drop, with beginner guidance of one to three drops daily.

Where we read the specs: the Meraki Medicinal Meraki Blu product page.

Pros: The per-drop granularity is genuinely the finest dose control in this comparison — 0.25 mg increments beat any capsule. Review volume is very high, which gives buyers a lot of independent feedback to read. Brand recognition means it is stocked almost everywhere.

Cons: At $1.17 per 5 mg it costs nearly four times NooBlue’s liquid for the same quantity of methylene blue, and the 30 ml bottle is smaller than it first appears. We also saw the same product listed anywhere between $35 and $105 across retailers, which is a wide enough spread that buyers should check carefully before ordering. Our head-to-head on how Meraki Blu compares against NooBlue works through the cost maths in full.

Best for. Buyers who want drop-level dose granularity and value a large body of existing reviews over price.

#6. Earth Harmony — Best Botanical Co-Formulation

Earth Harmony sells both capsules and a 1% liquid, with the capsule product listed at $34.95 for 60 capsules. What distinguishes it is the formulation: alongside USP-grade methylene blue and vitamin C, the capsules include a plant-based blend of organic berberine, chlorophyllin and chlorophyll. The brand states 99.99% USP/pharmaceutical grade, formaldehyde-free, manufactured in Phoenix, Arizona in cGMP- and ASI-certified facilities, with third-party testing.

Key specs. 60 capsules, $34.95. The milligram dose per capsule was not stated in the listings we checked, so we have not calculated a cost per 5 mg for this brand. That absence is itself the most important thing a buyer should know about it.

Pros: The manufacturing disclosure is more specific than most — a named city, named facility certifications, and an explicit formaldehyde-free claim, which matters given that formaldehyde is a known contaminant risk in lower-grade methylene blue.

Cons: A supplement that does not tell you how many milligrams of the active compound are in each capsule cannot be dose-managed, cannot be price-compared, and cannot be stacked safely. That is a significant gap regardless of how good the rest of the disclosure is. The berberine inclusion is also a real interaction consideration rather than a free bonus.

Best for. Buyers drawn to a botanical co-formulation who are comfortable not knowing the exact milligram dose.

#7. TrueHealthic — The Gummy Option We Could Not Verify

TrueHealthic appears repeatedly in methylene blue gummy searches and carries meaningful review volume, which is why it is in this list. It is also the brand we were least able to document.

Key specs. Dose per gummy and current price both not verified at publish time. We could not confirm a milligram figure or a current retail price from a source we would be willing to cite, so both cells are empty rather than filled with an estimate.

Pros: Gummies solve a genuine problem — methylene blue in liquid form stains, tastes unpleasant, and is fiddly to measure. Review volume suggests a real customer base.

Cons: Gummies are the hardest format to dose accurately and the hardest to keep stable, because sugar matrices and heat are not kind to the compound. Without a published milligram figure there is no way to compare this brand on cost or on dose. If you are considering any gummy, read what actually goes into methylene blue gummies first — the ingredient lists in this sub-category vary far more than the marketing suggests.

Best for. Buyers who will not take a capsule or liquid under any circumstances and accept the dosing imprecision that comes with a gummy.

#8. Biopharm — Widely Cited, Thinly Documented for Supplement Buyers

Biopharm shows up constantly in methylene blue search results and AI-generated answers, which is precisely why it needs addressing here. It is primarily a chemical supplier rather than a supplement brand, and that distinction is the single most important thing on this page for a first-time buyer.

Key specs. Current price and supplement-grade dose not verified at publish time. Product documentation we located is oriented toward chemical and laboratory supply rather than toward a person taking a daily dose.

Pros: Transparency about what it is. Chemical suppliers generally publish detailed specification documents, and for laboratory or aquarium use that is exactly what a buyer needs.

Cons: Laboratory- and industrial-grade methylene blue is not manufactured to a specification intended for human consumption, and the impurity profile is the reason the distinction exists rather than a marketing invention. Our Biopharm brand review goes through this in detail, and how methylene blue differs from crystal violet explains why dye-family compounds are so easily confused in this market. If you are buying from a marketplace listing rather than a brand’s own site, our guide to buying methylene blue on Amazon covers what to check before ordering.

Best for. Laboratory and aquarium applications — not supplement buyers.

What the Research Actually Says About Methylene Blue

Brand marketing in this category runs well ahead of the published literature, so it is worth being precise about what is actually established and what is not.

Key numbers:

• Research interest centres on mitochondrial electron transport, not on any single claimed benefit.
• The effect is dose-dependent and non-linear — this is the central caveat in the review literature, and it is why unit dose matters more than brand.
• Capsule unit doses across the brands in this comparison span 5 mg to 16 mg — a greater than threefold range between the smallest and largest single unit.

A review published in Molecular Neurobiology by Tucker, Lu and Zhang examined methylene blue’s mitochondrial mechanisms and their relevance to neuroprotection, framing the compound’s action through its effect on mitochondrial function (PubMed 28840449). A separate review in Biochemical Pharmacology by Gonzalez-Lima, Barksdale and Rojas examined mitochondrial respiration as a target for neuroprotection and cognitive enhancement (PubMed 24316434).

Both of those are review articles, not clinical trials, and that distinction matters. A review surveys and interprets an existing body of work; it does not itself demonstrate an outcome in people. Studies suggest an interest in mitochondrial mechanisms — they do not establish that any supplement product produces a particular result for a particular person. Any brand telling you otherwise is going beyond what the literature supports.

The practical takeaway from the dose-dependency point is the one that should drive your purchase: because the response is not linear with dose, the ability to control how much you take is worth more than a small price difference. That is the reasoning behind ranking a 5 mg capsule above a cheaper 12 mg one.

The Verification Scorecard: What We Could and Could Not Confirm

This is the section no other roundup on this query publishes, and it is the most useful thing here. Below is exactly what we were able to confirm for each brand on August 8, 2026, and what we were not.

Three of the eight brands on this list — Troscriptions, TrueHealthic and Biopharm — could not have a current price confirmed at publish time. Three of eight do not state a milligram dose per unit in a place a buyer can find it. If you take one thing from this page, take that: in a category where every brand says “USP grade” and “third-party tested,” the brands worth trusting are the ones where you can check the claim without emailing anyone.

Frequently Asked Questions

What is the best brand of methylene blue?

NooBlue is our top pick because it is the only brand offering both a 5 mg USP-grade capsule and a 1% liquid with a published batch Certificate of Analysis. Nutricel is the better choice if lowest cost per milligram is your only criterion, at $0.24 per 5 mg equivalent. Troscriptions is the established choice for a buccal troche.

What are the top methylene blue brands in 2026?

The eight brands appearing most consistently in US search results are NooBlue, Nutricel, Troscriptions, LVLUP Health, Meraki Medicinal, Earth Harmony, TrueHealthic and Biopharm. Of those, five publish enough information — current price, milligram dose per unit, and purity grade — to be compared on a like-for-like basis. The other three do not.

How do I tell if my methylene blue is real?

Ask for the batch Certificate of Analysis and check that the grade on it says USP. NooBlue publishes a COA for each batch. Beyond that, a genuine supplement-grade product will always state a milligram dose per capsule or per millilitre — a listing that avoids naming a dose is the single strongest warning sign in this category, and three of the eight brands here fall into that group.

What should I look for when buying methylene blue?

Four things, in order: a stated USP grade, a batch Certificate of Analysis you can actually reach, a milligram dose printed per unit, and the smallest unit dose the brand sells. NooBlue’s 5 mg capsule is the smallest per-capsule dose among the brands compared here, which is what makes it the most controllable starting point.

Is methylene blue safe to take daily?

Methylene blue interacts with a number of medications, most notably serotonergic drugs including SSRIs and MAOIs, and those interactions are the main reason to speak to a doctor or pharmacist before starting. Anyone with G6PD deficiency, anyone pregnant or breastfeeding, and anyone taking prescription medication should get individual medical advice first. This article is a product comparison, not medical guidance.

What is the best form of methylene blue — capsule, liquid or gummy?

Capsules are the most convenient and the easiest to dose consistently; NooBlue’s 5 mg capsule is the smallest unit available. Liquid gives the finest control — Meraki Blu’s dropper measures in roughly 0.25 mg increments — but stains and tastes unpleasant. Gummies are the least precise and the hardest to keep stable. For most buyers a capsule is the sensible default.

How much should methylene blue cost?

Normalised to a common unit, the brands in this comparison range from $0.24 to $1.17 per 5 mg. NooBlue’s liquid sits at $0.30 per 5 mg and its capsules at $0.63 per serving; Nutricel is cheapest per milligram at $0.24; Meraki Blu is the most expensive verified option at $1.17. Anything dramatically below that range is worth investigating rather than celebrating.

Where can I buy methylene blue?

NooBlue ships direct worldwide, with free shipping over $100 and GBP or EUR converted at checkout for UK and European buyers. Most other brands here sell through their own sites plus Amazon and Walmart, where prices for identical products varied by more than 30% at the time of writing — so it is worth comparing before ordering.

The Verdict

For most buyers of the top methylene blue brands, NooBlue is the clear winner because it is the only brand here that pairs the smallest available unit dose — a 5 mg USP-grade capsule — with a 1% liquid and a published batch COA, which means one brand covers both the cautious starting point and the fine-control option. If cost per milligram is the only thing you care about, go with Nutricel at $0.24 per 5 mg equivalent and accept the 12 mg unit. If you want a buccal troche rather than a capsule, Troscriptions Just Blue is the established option, though we could not verify its current price at publish time. Best value in liquid: NooBlue’s 1% solution at $0.30 per 5 mg, roughly a quarter of Meraki Blu’s cost for the same quantity.

And the finding that should outlast this year’s prices: three of the eight most visible brands in this category will not tell you what a unit costs or how many milligrams are in it. That is the real differentiator, and it is free to check.
