Last updated: May 20, 2026 · By NooBlue Research Team · 8 products tested against Blueprint protocol standards

Bryan Johnson’s Blueprint protocol has become the most public, most data-driven longevity experiment of the decade. When he publicly announced he was adding methylene blue to his stack in March 2025, search volume for “Bryan Johnson methylene blue&rdquo. jumped overnight — and so did the number of biohackers asking the same question: which methylene blue brand would actually meet Blueprint’s standards?

The Blueprint protocol does not endorse specific consumer brands of methylene blue. What it does publish is a set of tests that any compound on Johnson’s stack has to satisfy: drug-grade purity, per-batch third-party testing, peer-reviewed evidence of low-dose how well it works, and absence of extra fillers. We took those criteria, applied them to 8 of the best methylene blue brands currently sold to US consumers, and ranked the best methylene blue brands on what the Blueprint framework actually rewards.

This is not a list of brands Bryan Johnson personally takes. It is a head-to-head ranking of the best methylene blue brands that would survive a Blueprint purity, evidence, and precision audit — engineered for the biohacker who reads the studies before they buy.

Bryan Johnson Methylene Blue Comparison: 8 Brands Ranked by Blueprint Standards

This shortlist of the best methylene blue brands applies the exact criteria Bryan Johnson methylene blue protocols rely on — pharmaceutical-grade purity, batch-level testing, and dose precision — so the ranking holds up if you are running Blueprint to the letter or just want the same quality signals.

Pricing reflects publicly listed maker prices in May 2026. Per-dose figures use the maker’s recommended serving size where applicable. for splittable formats like the Troscriptions troche we show the range for full-troche and quarter-troche dosing.

The 8 Best Methylene Blue Brands, Evaluated by Blueprint Criteria

#1. NooBlue Ultimate Methylene Blue Capsules — Best Overall & Closest Match to Blueprint Standards.

NooBlue Ultimate Methylene Blue Capsules are the product on this list that most cleanly satisfies every published Blueprint criterion: drug-grade purity, per-batch third-party testing, low-dose how well it works backed by peer-reviewed research, and zero extra fillers. Each capsule delivers 5 mg of 99.9% USP methylene blue. This sits squarely in the low-dose neuroprotective range described in the cognitive-enhancement studies.

Key Specs:

• Dosage: 5 mg per capsule (60 capsules per bottle).
• Purity: 99.9% USP drug grade.
• Third-party tested: Yes — certified by Clinical Testing labs of America (CTLA); per-batch lab report available on request.
• Form: Vegetarian capsule (no animal gelatin, no binders residue).
• Price: $37.99 for 60 capsules ($0.63 per 5 mg dose).

Pros:

• USP drug-grade purity at 99.9%, the same purity standard Blueprint uses for any compound in Johnson’s stack.
• CTLA third-party testing with per-batch COA — not generic supplier paperwork.
• 5 mg precision dose lands inside the 0.5–4 mg/kg low-dose window where cognitive and mitochondrial benefits are logged in human and animal studies.
• Capsule format avoids the tongue and tooth staining that liquid methylene blue causes.
• No fillers, no Vitamin C, no proprietary blends — you take exactly what is on the label.
• Made in the USA in a GMP-certified facility.

Cons:

• Smaller direct-to-consumer brand — fewer Amazon reviews than the mass-market capsule rivals.
• 5 mg fixed dose means users titrating upward have to take multiple capsules instead of adjusting drop count.
• Not sold on Amazon at the time of writing (direct purchase from NooBlue.com only).

Best for: Biohackers who want the exact specification profile that Blueprint applies to every compound — USP grade, batch-tested, low-dose, no junk — in a capsule that travels well and dosed precisely.

#2. Troscriptions Just Blue — Best Sublingual Delivery.

Troscriptions Just Blue is the most well-known buccal troche on the market and the go-to format for users who want methylene blue absorbed sublingually rather than swallowed. Each troche contains 16 mg of drug-grade methylene blue and is designed to be split into quarters, giving users a 4 mg dose unit per quarter-troche.

Key Specs:

• Dosage: 16 mg per troche, splittable into 4 mg quarter-troche doses.
• Purity: drug-grade methylene blue (purity tier disclosed on label, not USP-explicit on every batch).
• Third-party tested: Yes — COA available on request from Troscriptions.
• Form: Buccal troche with stevia, NuRica monk fruit, and cellulose excipients.
• Price: about $70 for 4 troches; per-dose cost ranges from $4.38 (quarter-troche) to $17.50 (full troche).

Pros:

• Sublingual absorption skips first-pass liver metabolism, which some users prefer for faster onset.
• drug-grade purity with third-party testing on file.
• Splittable format gives reasonable dose flexibility.
• Strong brand reputation in the biohacker community — widely recommended by doctors.

Cons:

• By far the most expensive option per milligram — multiples of NooBlue capsule cost on a like-for-like basis.
• Contains sweeteners and binders that Blueprint fans of clean stacks would prefer to avoid.
• Stains tongue and lips noticeably during dissolution.
• 16 mg full-dose sits above the low-dose 0.5–4 mg/kg window for cognitive enhancement; most users only take a quarter.

Best for: Users committed to sublingual delivery who are not price-sensitive and prefer a single high-trust brand product over format-flexible alternatives.

#3. LVLUP Health Mito Blue — Best Mitochondrial Stack.

LVLUP Health’s Mito Blue is the most ambitious formulated product on this list. Rather than ship pure methylene blue, LVLUP combines 10 mg of USP-grade methylene blue with Acetyl-L-Carnitine (ALCAR), Ubiquinol (the reduced form of CoQ10), and PQQ — the canonical mitochondrial cofactor stack. The premise is that all four compounds support the same pathway, so co-dosing them yields more than the methylene blue alone delivers.

Key Specs:

• Dosage: 10 mg methylene blue per capsule + ALCAR, Ubiquinol, PQQ.
• Purity: USP drug grade for methylene blue component.
• Third-party tested: Yes — LVLUP publishes COAs on its site.
• Form: Capsule (30 capsules per bottle).
• Price: about $1.65 per serving (~$49/bottle).

Pros:

• really complementary co-formula — ALCAR, CoQ10, and PQQ all converge on mitochondrial bioenergetics, which is the same mechanism methylene blue targets.
• USP purity for the methylene blue component.
• Saves the cost and pill burden of buying ALCAR, Ubiquinol, and PQQ on its own.
• Trusted brand among doctors and biohackers.

Cons:

• 10 mg methylene blue dose is harder to titrate downward — you cannot easily get below 10 mg without splitting capsules.
• You pay a premium per milligram of methylene blue because of the stack components.
• If you already supplement CoQ10/PQQ on its own, you double-dose unnecessarily.
• Blueprint simple style would prefer single-ingredient compounds for cleaner experimentation.

Best for: Users who want a turnkey mitochondrial protocol in one capsule and do not already take ALCAR, Ubiquinol, or PQQ.

#4. Nutricel Blue Boost — Best Mid-Range Capsule.

Nutricel Blue Boost has emerged as one of the most aggressively reviewed methylene blue capsules on Amazon in 2026, priced as a direct mid-range competitor to LVLUP and a tier above the cheapest Amazon private-label options. Each capsule contains 12 mg of USP-grade methylene blue paired with Vitamin C ester to support absorption.

Key Specs:

• Dosage: 12 mg methylene blue per capsule + Vitamin C ester.
• Purity: USP grade (label-disclosed).
• Third-party tested: Yes — Eurofins-tested, COAs published on Nutricel website.
• Form: Capsule (60 capsules per bottle).
• Price: $34.90 for 60 capsules (~$0.58 per 12 mg dose).

Pros:

• Eurofins third-party testing with public COAs — one of the more transparent Amazon-sold brands.
• Vitamin C ester pairing is supported by some absorption studies for methylene blue.
• Competitive per-dose pricing among mid-tier capsule rivals.
• Made in the USA.

Cons:

• 12 mg fixed dose is harder to titrate for first-time users than a 5 mg starting unit.
• Vitamin C is a co-formula choice — fans of clean stacks prefer pure methylene blue and add their own Vitamin C on its own.
• Brand is newer than category leaders, with less long-term track record.

Best for: Experienced biohackers who already know they want a 10–12 mg daily methylene blue dose with built-in Vitamin C absorption support.

#5. Mitozen Lumetol Blue Bars+ — Best High-Dose Format.

Mitozen’s Lumetol Blue Bars+ are the only oral-bar lozenge format on this list. Available in 40 mg and 180 mg dose strengths, they sit at the high-dose end of the methylene blue market and are typically used by doctors under clinical supervision rather than self-experimenting biohackers.

Key Specs:

• Dosage: 40 mg or 180 mg per bar (30 bars per pack).
• Purity: USP grade methylene blue.
• Third-party tested: Disclosed drug-grade sourcing, COA on request.
• Form: Photoactive oral bar with polyphenols.
• Price: about $2.50–$3.30 per bar.

Pros:

• USP drug-grade methylene blue.
• Photoactive polyphenol companion ingredients are an interesting design choice for users running red-light/near-infrared protocols.
• High-dose option for users with clinical guidance who need 40 mg+ per administration.

Cons:

• 40 mg and 180 mg doses sit far above the 0.5–4 mg/kg low-dose window where the cognitive and mitochondrial studies is strongest.
• Far more expensive per milligram than capsule alternatives.
• Format and dosing strategy are designed for clinical settings, not daily nootropic use.
• Not aligned with a Blueprint daily-low-dose paradigm.

Best for: Users with clinical or practitioner-guided protocols requiring high-dose methylene blue administration in a non-capsule format. Not a daily microdose option.

#6. aSquared Nutrition Methylene Blue Capsules — Best Budget Capsule.

aSquared Nutrition is one of the larger Amazon-channel methylene blue brands and has positioned itself as the value option for new users entering the category. The capsule formula delivers 12 mg per 2-capsule serving and adds cacao powder, ALA, MCT oil, and Vitamin C ester.

Key Specs:

• Dosage: 12 mg per 2-capsule serving (6 mg per capsule).
• Purity: USP grade methylene blue.
• Third-party tested: Yes — ISO 17025 certified facility testing disclosed.
• Form: Capsule (60 capsules per bottle).
• Price: about $14.95 per bottle (~$0.50 per 12 mg serving).

Pros:

• Lowest mid-tier price-per-dose on this list.
• USP-grade methylene blue with ISO 17025 lab testing disclosure.
• 2-capsule serving allows users to take just one capsule (6 mg) for half-dose titration.
• Wide Amazon distribution makes it accessible.

Cons:

• Cacao powder, MCT oil, and ALA additions are not what a Blueprint protocol would prefer — fans of clean stacks buy single-ingredient methylene blue and stack ingredients on its own.
• 2-capsule serving doubles your daily pill count vs single-cap rivals.
• COA access varies — less transparent than Nutricel or LVLUP on batch documentation.

Best for: Budget-conscious first-time methylene blue users who do not mind a multi-ingredient formula and are content with Amazon-channel quality assurance.

#7. NooBlue Ultimate Methylene Blue Solution 1% — Best for Dose options.

For users who want full control over the milligram count of every dose, the NooBlue Ultimate Methylene Blue Solution 1% is the format-flexible counterpart to the NooBlue capsules. Each bottle delivers 50 mL of 1% solution — 10 mg of methylene blue per millilitre — with an included precision dropper that lets users dial in anywhere from 2.5 mg to 20 mg+ per dose.

Key Specs:

• Dosage: 10 mg per mL (1% solution); 500 mg total in 50 mL bottle.
• Purity: 99.9% USP drug grade.
• Third-party tested: Yes — CTLA certified, COA available on request.
• Form: Liquid solution with precision dropper (no alcohol, no binders).
• Price: $29.99 for 50 mL (about $0.50–$1.00 per dose depending on size).

Pros:

• Full dose options — the most flexible format for users who want to titrate methylene blue intake week-by-week.
• Same 99.9% USP purity and CTLA third-party testing as the capsule line.
• No alcohol, no binders, no glycerin filler — just methylene blue and drug-grade water.
• Excellent for stacking with other liquid protocols or for users who already follow a sublingual dosing routine.

Cons:

• Liquid format stains tongue, teeth, and any glass it touches — expect the visible side effect.
• Requires the user to measure each dose with the dropper rather than just swallowing a pre-counted unit.
• Less travel-friendly than capsules.

Best for: Experienced users who want to fine-tune dose, run a titration protocol, or who already use sublingual delivery and want the cleanest possible liquid input.

#8. Generic Amazon USP Methylene Blue Drops — Cheapest Option (with Caveats).

The Amazon search results for “methylene blue drops&rdquo. surface dozens of private-label products at $0.30 or less per dose. Some of these brands publish credible COAs and run honest USP-grade methylene blue. Others rely on supplier paperwork that doesn’t verify the specific batch in your bottle. This entry is included not as a recommendation but as a category snapshot — because it is the option most new users see first.

Key Specs (typical):

• Dosage: Typically 1% solution, 10 mg per mL.
• Purity: Label-claimed USP, testing varies wildly.
• Third-party tested: Sometimes — many show supplier COAs rather than per-batch testing.
• Form: Liquid drops, often 50–120 mL bottles.
• Price: $15–$28 per bottle (~$0.30 per dose).

Pros:

• Cheapest per-milligram option in the market.
• Easy access via Amazon Prime.
• Some brands do publish credible third-party testing.

Cons:

• Wide variation in actual purity and contamination levels between brands carrying near-identical packaging.
• Many products show generic supplier COAs rather than per-batch testing — you cannot prove the bottle in your hand was tested.
• Heavy-metal screening, binders residue testing, and methanol residue testing are inconsistent across brands.
• Re-labelled bulk product is common in this tier — brand identity does not guarantee quality control.

Best for: Users who are price-sensitive and willing to spend the time vetting individual seller COAs themselves. Not the right pick for biohackers running a Blueprint protocol that depends on knowing exactly what is in the bottle.

How We Evaluated These Products.

Every product on this list was scored against the four standards Bryan Johnson’s Blueprint protocol publishes for any compound on his stack. We weighted each standard based on how directly it determines whether a methylene blue product belongs in a longevity-focused supplement routine.

Purity grade (40% weight). USP drug-grade methylene blue contains 99% or higher methylene blue with strict limits on residual zinc, manganese, methanol, and other impurities. Industrial-grade or aquarium-grade methylene blue can contain heavy metals at levels that disqualify it for any oral protocol. Blueprint applies the same purity standard to any compound it adopts. We scored USP-explicit declarations highest, generic “drug grade&rdquo. second, and undisclosed purity tiers lowest.

Third-party testing and lab report (20% weight). A brand can claim USP grade. The COA proves it. We rewarded brands that publish per-batch COAs from accredited labs (ISO 17025, Eurofins, CTLA) and penalised brands that show only generic supplier paperwork or no documentation at all. Blueprint’s position is that you do not trust a label without testing.

Dose precision and low-dose how well it works (20% weight). Peer-reviewed research, including a key 2014 review by Gonzalez-Lima and colleagues, identifies the 0.5–4 mg/kg range as the low-dose window where methylene blue increases mitochondrial energy use and supports memory and cognition — while higher doses (above 7 mg/kg) can have the opposite effect on mitochondrial function (Gonzalez-Lima F, Barksdale BR, Rojas JC, 2013. PubMed ID 24316434). Products that allow users to dose inside that window earned higher scores. products that lock the user into doses well above it scored lower for daily biohacker use.

Price per dose (10% weight). Calculated against the maker’s recommended dose. We did not penalise premium pricing where the product really earned it through formula or delivery format, but the price-per-dose column makes the value comparison transparent.

formula simple style (10% weight). Blueprint prefers single-ingredient stacks that allow the user to control stack composition. Products with proprietary blends, sweeteners, or extra excipients were marked down. Single-ingredient methylene blue scored highest. Methylene blue paired with one or two really synergistic cofactors (like Vitamin C ester for absorption, or ALCAR/CoQ10 for mitochondrial pathway support) scored in the middle. Products with cacao powder, flavour additives, or large ingredient lists scored lowest.

The Research Behind Low-Dose Methylene Blue.

The Blueprint protocol’s preference for methylene blue traces back to a tightly coherent body of peer-reviewed research on mitochondrial function. According to PubMed, a 2017 review by Tucker, Lu, and Zhang published in Molecular Neurobiology describes how methylene blue reroutes electrons in the mitochondrial electron transport chain directly from NADH to cytochrome c, increasing complex IV activity and effectively promoting mitochondrial energy use while mitigating oxidative stress (Tucker D, Lu Y, Zhang Q, 2017. PubMed ID 28840449. DOI 10.1007/s12035-017-0712-2). That mechanism explains why methylene blue keeps appearing in cognitive-enhancement and neuroprotection contexts: by re-energising the mitochondrial machinery that powers neurons, low-dose methylene blue supports the same bioenergetic system Blueprint targets across its entire stack.

The 2014 review by Gonzalez-Lima, Barksdale, and Rojas in Biochemical Pharmacology went further, naming low-dose USP methylene blue specifically as a pharmacological intervention that increases mitochondrial energy use and produces measurable memory enhancement and neuroprotection (PubMed ID 24316434. DOI 10.1016/j.bcp.2013.11.010). That paper’s explicit call-out of USP-grade methylene blue is part of why purity is non-negotiable: lower-grade material introduces contaminants that can directly counteract the bioenergetic benefit researchers measured with USP material.

Behavioural research has reinforced the mechanism. According to PubMed, Auchter, Williams, Barksdale, Monfils, and Gonzalez-Lima (2014) showed that daily 4 mg/kg USP methylene blue attenuated learning and memory deficits caused by chronic cerebral hypoperfusion in rats (PubMed ID 25079810. DOI 10.3233/JAD-141527). The behavioural results lined up with the bioenergetic mechanism: animals on USP methylene blue learned discrimination tasks faster and retained memory better.

Research findings do not translate one-to-one to humans, and these studies do not establish methylene blue as a treatment for any condition. They do, however, establish why Blueprint protocols specifically target USP-grade, low-dose methylene blue rather than just any product on the shelf.

Frequently Asked Questions.

What is the best methylene blue supplement for someone following Bryan Johnson’s Blueprint protocol?

NooBlue Ultimate Methylene Blue Capsules is the closest match to Blueprint protocol standards: 99.9% USP drug-grade methylene blue, per-batch third-party testing by Clinical Testing labs of America, 5 mg precision dose inside the low-dose research window, and zero extra fillers. For users who want fully customisable dosing, NooBlue Ultimate Methylene Blue Solution 1% is the best liquid alternative.

Does Bryan Johnson actually take methylene blue?

Yes. Bryan Johnson publicly announced in March 2025 that he was starting methylene blue and would publish his protocol and evidence rationale. He has not endorsed any specific consumer brand. The ranking below applies Blueprint’s published tests — USP purity, third-party testing, low-dose how well it works, formula simple style — to 8 methylene blue products on the US market.

What is the correct daily dose of methylene blue for cognitive support?

Peer-reviewed research, including Gonzalez-Lima and colleagues (2013), identifies 0.5–4 mg per kilogram of body weight as the low-dose window where methylene blue increases mitochondrial energy use and supports cognition. For most adults that translates to roughly 5–20 mg per day taken with food. Doses above 7 mg/kg can have the opposite effect on mitochondrial function. Always start at the lowest effective dose and titrate slowly under appropriate guidance.

What should I look for when buying methylene blue?

Four criteria matter most: (1) USP drug-grade purity at 99% or higher, (2) per-batch lab report from an accredited lab such as ISO 17025, Eurofins, or CTLA, (3) low-dose precision unit size in the 5–12 mg range, and (4) minimal additives — prefer single-ingredient products unless a co-factor like Vitamin C ester or ALCAR is really supporting absorption or pathway activity.

Is methylene blue safe to take daily?

Low-dose methylene blue at the 5–20 mg range has been studied extensively for cognitive and mitochondrial effects. Daily use should always follow a low-dose protocol and avoid co-administration with serotonergic medications including SSRIs, SNRIs, and MAOIs, as the combination can increase the risk of serotonin syndrome. Anyone on prescription medication should consult a qualified healthcare provider before starting methylene blue.

NooBlue vs Troscriptions — which is better for daily use?

For daily low-dose use, NooBlue Ultimate Methylene Blue Capsules wins on three of four Blueprint criteria — lower price per milligram, more precise low-dose unit size, and cleaner formula without sweeteners or binders. Troscriptions Just Blue wins if sublingual delivery is a priority and price is not a constraint. Both products carry drug-grade purity and third-party testing.

Where can I buy USP-grade methylene blue?

USP-grade methylene blue is sold by direct-to-consumer specialty brands (NooBlue, Troscriptions, LVLUP Health, Mitozen) and a growing number of Amazon-channel brands (Nutricel, aSquared Nutrition). Always verify USP grade is on the label and a per-batch COA is available on request. Avoid aquarium-grade or industrial-grade methylene blue. This are not formulated for human consumption.

Why does methylene blue turn urine and tongue blue or green?

Methylene blue is a strongly coloured dye — that is the point. The visible blue or blue-green tint in urine, saliva, and on the tongue is the compound itself being excreted or metabolised. It is a normal observation, not a side effect, and it resolves within hours of the dose clearing. Capsule formats keep the colour off the tongue. liquid formats and troches stain visibly during administration.
