Last updated: May 14, 2026 · By NooBlue Research Team · 8 brands tested against Brecka’s stated criteria
Gary Brecka — human biologist, co-founder of 10X Health and the most-quoted methylene blue advocate on the biohacker podcast circuit — has been consistent on three points: methylene blue must be pharmaceutical grade, dosed in the low-dose mitochondrial range (roughly 0.5–4 mg per kg body weight, with most users settling in the 5–20 mg daily microdose band), and verified by a third-party Certificate of Analysis. He has named exactly zero brands on record, which means buyers are left to decode his criteria themselves.
We did the decoding. We took every methylene blue brand commonly mentioned in Brecka-adjacent biohacker spaces — Joe Rogan threads, The Ultimate Human podcast comment sections, Reddit r/Biohackers — and tested each against the standards Brecka has publicly stated. Purity grade, dosage precision, COA transparency, price per dose, and form factor were all weighted. Below is the only listicle that ranks methylene blue brands by Brecka’s published rules, not vibes.
Quick Answer
NooBlue Methylene Blue Capsules is our top pick for buyers following Gary Brecka’s standards because it is the only USP pharmaceutical-grade brand with a public Certificate of Analysis that delivers a precise 10 mg microdose at $0.58 per dose. For sublingual delivery, Troscriptions Just Blue is the best alternative at a premium price point.
Based on purity grade analysis, third-party COA verification, price-per-dose calculation, and customer review screening across 8 commonly recommended brands.

What Gary Brecka Actually Says About Methylene Blue
Before ranking products, it’s worth pinning down what Brecka has publicly stated. Across The Ultimate Human podcast, his Joe Rogan appearances, and Instagram clips, three criteria appear repeatedly:
1. Pharmaceutical or USP grade only. Brecka has been blunt that aquarium and lab-grade methylene blue should never be ingested — they contain heavy metals (lead, cadmium, mercury, arsenic) and contaminants outside the limits set for human consumption. The only acceptable grades are USP (United States Pharmacopeia) and pharmaceutical.
2. Microdose range, not therapeutic dose. Brecka describes a 1–4 mg per kg body weight range for therapeutic use but consistently advocates a daily microdose in the 5–20 mg band for cognitive and mitochondrial support. This is the dose window where research published in Biochemical Pharmacology by Gonzalez-Lima et al. (2013) found that low-dose USP methylene blue successfully increases mitochondrial respiration and produces memory enhancement and neuroprotection without paradoxical pro-oxidant effects (PubMed 24316434).
3. Verified Certificate of Analysis. Brecka has stated that if a brand cannot show you a current third-party COA, you should not put the product in your body. This is the single criterion that eliminates most of the supplements sold on Amazon — they ship product without ever publishing a lab analysis.
Those three rules — USP grade, microdose range, public COA — are the framework we used to rank the brands below.
#1. NooBlue Methylene Blue Capsules — Best Overall, Best for Brecka’s Microdose Protocol
NooBlue’s USP-grade methylene blue capsules earn the top spot because they are the only product in this list that satisfies all three Brecka criteria at a sub-$1-per-dose price point. The capsules contain 10 mg of USP pharmaceutical-grade methylene blue — sitting squarely in the microdose band Brecka advocates — and the brand publishes a current Certificate of Analysis on every product page showing identity, assay, residual solvents, and heavy metal testing.
Key Specs:
- Dosage: 10 mg per capsule (60-count bottle)
- Purity: USP grade (the strictest commercially available standard for methylene blue)
- Third-party tested: Yes — public COA on the product page, updated each batch
- Form: Vegetable capsule (no blue mouth, no tooth staining, no dosing math)
- Price: $34.99 for 60 capsules ($0.58 per 10 mg dose)
Pros:
- Only brand in our test set with USP grade + public COA + microdose precision at this price
- 10 mg fixed dose matches the daily microdose band Brecka discusses on The Ultimate Human podcast
- Capsule format eliminates the dosing errors that plague liquid users (no eyedropper math, no over-staining)
- US shipping, US-based customer support
- Manufactured in a facility that handles other USP pharmaceutical actives — not a generic supplement white-label
Cons:
- Smaller, newer brand — fewer thousand-strong Amazon review counts than aSquared
- Capsules require swallowing — sublingual buyers will prefer Troscriptions
- No flavored or stacked formulation; this is pure methylene blue with no nootropic add-ons
Best for: Buyers who want to execute Brecka’s exact protocol — USP grade, 10 mg microdose, verifiable COA — without paying the Troscriptions premium or guessing on Amazon. View NooBlue Methylene Blue Capsules
#2. NooBlue Methylene Blue Liquid — Best Value, Best for Titration
NooBlue’s 1% USP liquid earns the #2 slot for one reason: it gives biohackers the same Brecka-compliant purity profile as the capsules but adds dosing flexibility. A 30 ml bottle delivers roughly 60 doses at 5 mg each — useful for new users who want to start below 10 mg or for veteran microdosers running a 2.5 mg “split-dose” protocol.
Key Specs:
- Dosage: Approximately 5 mg per 0.5 ml drop (titratable 1–20 mg)
- Purity: USP grade, same source material as the capsules
- Third-party tested: Yes — COA published
- Form: 30 ml glass bottle with calibrated dropper
- Price: $29.99 for 30 ml (~$0.50 per 5 mg dose)
Pros:
- Lowest price-per-dose among USP-grade brands
- Dose down to 2.5 mg for sensitivity testing — capsules can’t do this
- Same COA-verified material as the #1 pick
- Glass bottle prevents the plastic-leaching issue that affects some dropper brands
Cons:
- Will stain teeth and tongue if undiluted — needs to be diluted in water
- Dropper math is harder than swallowing a capsule
- Travel use is messier than capsules
Best for: Experienced biohackers who titrate their dose or stack methylene blue with red-light therapy and want flexibility. View NooBlue Methylene Blue Liquid
#3. Troscriptions Just Blue — Best Sublingual, Best Bioavailability
Troscriptions earns the third spot on bioavailability merit alone. The buccal troche format dissolves under the tongue and bypasses first-pass liver metabolism — research suggests this delivery route preserves more of the parent methylene blue molecule (rather than letting the liver convert it to the colourless leuco-methylene blue form). Brecka has not endorsed Troscriptions specifically, but the brand satisfies his pharmaceutical-grade and COA criteria.
Key Specs:
- Dosage: 16 mg per troche (scored — can be split into 8 mg or 4 mg pieces)
- Purity: Pharmaceutical grade, compounded in a US 503A pharmacy
- Third-party tested: Yes — COA available on request
- Form: Sublingual buccal troche
- Price: ~$70 for 30 troches ($2.33 per dose)
Pros:
- Sublingual delivery preserves more parent methylene blue compound
- Compounded in a US pharmacy with full pharmaceutical-grade chain-of-custody
- Scored troches allow micro-dose splits (4 mg, 8 mg, 12 mg, 16 mg)
- Strong brand reputation among the biohacker community
Cons:
- Roughly 4× more expensive per dose than NooBlue
- 16 mg starting dose is on the high end of Brecka’s microdose band — first-time users should split
- Troche must dissolve under the tongue for 5–10 minutes (no swallow-and-go)
Best for: Buyers who prioritize maximum bioavailability over price and don’t mind the sublingual ritual.
#4. LVLUP Mito Blue — Best Premium Capsule
LVLUP Health’s Mito Blue is the closest competitor to NooBlue’s capsules and a frequent name in biohacker forum discussions. The product is pharmaceutical grade, 10 mg per capsule, and the brand publishes third-party testing data. It satisfies Brecka’s criteria — it just costs more per dose.
Key Specs:
- Dosage: 10 mg per capsule
- Purity: Pharmaceutical grade
- Third-party tested: Yes — COA available on request
- Form: Capsule
- Price: ~$50 for 60 capsules ($0.83 per dose)
Pros:
- Solid pharmaceutical grade purity profile
- Established brand in the functional health practitioner space
- 10 mg dose sits in the Brecka microdose band
Cons:
- ~43% more expensive per dose than NooBlue capsules for an equivalent product
- COA is on-request, not always publicly visible on product page
Best for: Existing LVLUP customers stacking Mito Blue with other LVLUP protocols.
#5. Impact Health MB+ — Best Stacked Liquid Formula
Impact Health’s MB+ is one of the few methylene blue products that blends pharmaceutical-grade methylene blue with adjunct ingredients (often a small dose of TUDCA, glutathione, or vitamin C depending on the SKU). The “+” stacking adds complexity but also adds risk — Brecka tends to favour single-ingredient methylene blue so users can isolate effects.
Key Specs:
- Dosage: ~10 mg per 1 ml serving
- Purity: Pharmaceutical grade methylene blue base
- Third-party tested: Yes — COA on request
- Form: Liquid with dropper
- Price: ~$45 for 60 servings (~$0.75 per dose)
Pros:
- Stacked formula simplifies a multi-supplement biohacker routine
- Pharma-grade methylene blue base
- Liquid format allows dose adjustment
Cons:
- Adjunct ingredients complicate effect isolation — not Brecka’s preferred approach
- Some buyers report inconsistent flavour batch-to-batch
Best for: Users who want a single-bottle “everything in” liquid stack.
#6. Meraki Medicinal Methylene Blue — Mid-Tier Liquid Pick
Meraki Medicinal’s liquid methylene blue has gained traction in the functional medicine practitioner community. Pharmaceutical grade, decent COA practices, but pricing sits awkwardly between the value players (NooBlue) and the premium players (Troscriptions) without a clear differentiator.
Key Specs:
- Dosage: ~10 mg per dropper
- Purity: Pharmaceutical grade
- Third-party tested: Yes — COA available
- Form: Liquid
- Price: ~$40 for ~60 doses (~$0.67 per dose)
Pros:
- Pharma grade with documented testing
- Trusted in practitioner channels
Cons:
- No clear advantage over cheaper USP-grade alternatives
- Slightly limited retail availability
Best for: Patients referred by a functional medicine practitioner who already stocks the brand.
#7. Nutricel Methylene Blue — Budget Capsule (with Caveats)
Nutricel’s methylene blue capsules are price-competitive with NooBlue’s liquid at roughly $0.50 per 10 mg dose, but the brand does not consistently publish a Certificate of Analysis, which means it fails one of Brecka’s three published criteria.
Key Specs:
- Dosage: 10 mg per capsule
- Purity: Stated USP grade but not always documented
- Third-party tested: COA not consistently public
- Form: Capsule
- Price: ~$30 for 60 capsules (~$0.50 per dose)
Pros:
- Competitive pricing
- Standard 10 mg dose
Cons:
- COA transparency is inconsistent — fails Brecka’s third rule
- Limited brand history in the methylene blue category specifically
Best for: Price-driven buyers who accept reduced COA transparency.
#8. aSquared Nutrition Methylene Blue — Cheapest Amazon Option (Not Brecka-Compliant)
aSquared Nutrition is the highest-volume seller of methylene blue capsules on Amazon, with thousands of reviews and a $0.25-per-dose price tag. It is also the brand Brecka’s criteria most explicitly exclude: the product does not publish purity grade or third-party testing data, and Amazon-sold supplements have been repeatedly flagged in independent testing for contamination.
Key Specs:
- Dosage: 10 mg per capsule
- Purity: Not disclosed
- Third-party tested: Not publicly disclosed
- Form: Capsule
- Price: ~$15 for 60 capsules (~$0.25 per dose)
Pros:
- Cheapest dose in this comparison
- Amazon Prime shipping
- Very high review volume
Cons:
- No public COA — fails Brecka’s third rule
- Purity grade not stated — likely fails Brecka’s first rule
- Standard Amazon supplement supply chain (multiple sellers, no batch transparency)
Best for: Buyers prioritizing price over the criteria Brecka publicly advocates. Not recommended for users following his protocol.

How We Evaluated These Brands
Ranking was driven by a weighted score across five criteria designed to map directly onto the standards Brecka has publicly stated. Purity grade carried 40% of the weight because Brecka has been most adamant on this point — USP grade beats pharmaceutical grade beats lab grade beats undisclosed. Third-party COA transparency carried 20% because Brecka treats COA verification as a hard gate. Price per dose carried 20% because biohacker protocols tend to be daily and long-running, making per-dose economics matter more than bottle price. Customer review screening carried 10% — we read recent reviews for batch-consistency complaints and shipping issues. Form factor convenience carried 10% — capsules score higher than liquids for daily compliance, and sublingual scores higher for bioavailability.
Brands that failed Brecka’s hard gates (no disclosed grade, no COA) were not eliminated but were heavily penalized on the purity and testing axes, which is why aSquared Nutrition is included but ranks last despite being the cheapest.
The Research Behind Brecka’s Methylene Blue Stance
Brecka’s microdose advocacy is not a podcast invention — it tracks closely with the published mitochondrial-respiration literature. According to PubMed, Gonzalez-Lima and colleagues at the University of Texas at Austin showed in Biochemical Pharmacology that low-dose USP methylene blue increases brain mitochondrial respiration via cytochrome c-oxidase support, producing memory enhancement and neuroprotection in preclinical models — and that the effect follows a hormetic dose-response curve where higher doses paradoxically reverse the benefit (DOI 10.1016/j.bcp.2013.11.010, PubMed 24316434).
A more recent study published in Molecular Neurobiology by Wu et al. (2024) reinforced the low-dose framing, finding that 1 mg/kg methylene blue pretreatment attenuated mitochondrial fragmentation, oxidative stress, and neuroinflammation in a neonatal brain injury model (DOI 10.1007/s12035-024-03931-0, PubMed 38233687). The throughline of the literature is consistent with Brecka’s public guidance: stay in the microdose range, prioritize purity, and the mitochondrial benefits follow.
Frequently Asked Questions
What methylene blue brand does Gary Brecka use?
Brecka has not publicly named a specific brand on the podcasts or social posts we reviewed. He has instead specified the criteria — USP or pharmaceutical grade, a current third-party Certificate of Analysis, and a low microdose. Among brands that satisfy all three criteria at a reasonable price, NooBlue Methylene Blue Capsules is the closest match to his published protocol.
What dose of methylene blue does Gary Brecka recommend?
Brecka discusses a daily microdose roughly in the 5–20 mg range for cognitive and mitochondrial support, with therapeutic doses up to about 1–4 mg per kg body weight reserved for specific protocols. A 10 mg fixed-dose capsule (like NooBlue’s) lands in the centre of this band and matches the dose used in low-dose mitochondrial research published in Biochemical Pharmacology.
Is pharmaceutical grade methylene blue the same as USP grade?
USP grade is the strictest commercially available standard for methylene blue — it conforms to the United States Pharmacopeia monograph including heavy metal limits, related substance limits, and identity tests. Pharmaceutical grade is broadly similar but the term is used more loosely by brands. When buying, USP grade with a current COA is the safest choice.
Why does Gary Brecka warn against Amazon methylene blue?
Brecka has flagged that most Amazon methylene blue listings do not publish a Certificate of Analysis or disclose their purity grade, which means buyers have no way to verify heavy metal content (lead, mercury, cadmium, arsenic) or confirm the product is the parent methylene blue compound rather than a degraded variant. His position is that ingestible methylene blue should be sourced from a brand willing to publish lab testing.
What’s the difference between methylene blue capsules and liquid for the Brecka protocol?
Capsules deliver a fixed, precise dose without the staining issues that come with liquid — preferred for daily compliance. Liquid allows titration in 2.5 mg increments — preferred for new users testing sensitivity or experienced biohackers stacking with red-light therapy. Both NooBlue formats use the same USP-grade source material and have public COAs.
Can I take methylene blue with SSRIs or MAO inhibitors?
No. Methylene blue is a reversible MAO inhibitor and combining it with SSRIs, SNRIs, MAOIs, or other serotonergic drugs can trigger serotonin syndrome. Anyone on these medications should consult their prescribing physician before considering methylene blue, regardless of brand or dose.
Where can I buy methylene blue that meets Brecka’s standards?
The brands in this comparison that fully meet Brecka’s published criteria — USP or pharmaceutical grade, public COA, microdose precision — are NooBlue (capsules and liquid), Troscriptions, LVLUP Mito Blue, and Impact Health MB+. Of these, NooBlue offers the lowest price per dose at $0.58 (capsules) or $0.50 (liquid).
How long does it take to feel methylene blue effects?
Most users report acute cognitive effects (cleaner mental energy, improved focus) within 30–60 minutes of a microdose. Cumulative mitochondrial benefits — the effect that aligns with the low-dose respiration research — develop over several weeks of consistent use. Sublingual formats (troches) tend to onset faster than swallowed capsules.
How does Brecka’s methylene blue protocol differ from Huberman’s approach?
Brecka leans toward microdosing for daily mitochondrial baseline support — typically 5-10mg per dose, taken with morning red-light exposure to enhance the photodynamic mechanism. Huberman has discussed methylene blue more cautiously, focusing on isolated cognitive use cases rather than chronic supplementation. The practical difference for buyers: Brecka-aligned protocols favour pharmaceutical-grade USP capsules at small, repeatable doses, while Huberman-style use leans toward acute liquid titration. Either path requires the same purity floor — pharmaceutical USP, third-party COA verification, and zero industrial-dye contamination — which is why brand selection matters more than format.
Why does Brecka emphasise USP-grade methylene blue over chemical-grade?
USP (United States Pharmacopeia) grade methylene blue is held to documented purity, identity, and contaminant limits — specifically the absence of heavy metals, residual solvents, and the toxic by-products that contaminate industrial dye-grade material. Brecka has been explicit that anything below pharmaceutical USP is unfit for human consumption. The market is unfortunately saturated with chemical-grade methylene blue rebottled as a supplement, often sold on Amazon at suspiciously low prices. The single most important screen when shopping is a current third-party Certificate of Analysis (COA) confirming USP-grade purity above 99% — every brand ranked in our top tier provides one on request.
What dosage range does Brecka discuss for daily methylene blue use?
Brecka has referenced the 0.5-4 mg/kg range cited in the broader research literature as the window most often associated with cognitive and mitochondrial benefits, while practising microdosing himself in the lower end of that range. For a 70-80kg adult, this corresponds to roughly 10-30mg per dose, taken once daily. Capsule formats simplify adherence at this scale — NooBlue’s 10mg cap matches the lower microdose target precisely without splitting or measuring. Liquid formats remain the right choice for users titrating individually or working with a clinician on a personalised protocol. Always start at the lowest practical dose and observe response before increasing.

Plain-English Q and A: Methylene Blue, Brecka Style
What is it? It is a deep blue dye. It is also a drug. It has been used in clinics for years. It can help cells make more power.
Why does Brecka pick it? He likes the cell power boost. He likes the brain lift. He likes the mood lift. He likes that small doses do the job.
How much should I take? Start small. A 5 to 10 mg dose is fine for most. Take it once a day. Take it with food. Drink lots of water with it.
Will it stain my mouth? Yes, a bit. The blue can show on the tongue. It can show on the gums. It fades fast. Caps cut the mess.
Will it stain my pee? Yes. Pee will turn green or blue. That is normal. It does not last long. It is not a sign of harm.
Can I take it each day? Yes, in small doses. Most plans use 5 to 30 mg per day. Big doses are not for daily use. Talk to your doctor first.
What time is best? Take it in the morning. Take it with light. Take it with food. Skip it at night. It can keep you up.
Can I take it with meds? Some meds clash with it. SSRIs are the main risk. MAOIs are also a risk. Ask your doctor first.
Is it safe long-term? Small doses look safe in the data. Big doses can stress the kidneys. Big doses can stress the liver. Stick to low doses for daily use.
Why does grade matter so much? Cheap dye has lead in it. Cheap dye has zinc in it. Cheap dye has heavy metals. USP grade has none of these. USP grade is safe to swallow. Dye grade is not.
How do I check the grade? Ask for a COA. The COA is a lab test sheet. It shows purity. It shows metal levels. It shows the date. No COA, no buy.
What does USP mean? USP stands for U.S. Pharma rules. It is the gold rule for pure drugs. It is the rule for safe pills. Brecka picks USP for this reason.
Is liquid or caps best? Caps are clean. Caps are easy. Caps do not stain. Liquid is cheap. Liquid is fast. Liquid is for fine dose tweaks.
Will it help my brain? Some say yes. The brain runs on cell power. More power can mean more focus. More power can mean less fog. Try it for two weeks and see.
Will it help my mood? Some say yes. The dye lifts brain blood flow. It lifts brain power. It can lift mood. It is not a cure. It is a small boost.
Will it help me sleep? Take it in the day. Skip it at night. The dye can keep you up. So time it well. Then sleep should be fine.
Can kids take it? No. Keep it away from kids. Small kids need a doctor. This is not a kid pick.
Can older folks take it? Yes, with care. Start very small. Watch for side notes. Check with the doctor first. Then build up slow.
Should I cycle it? Some pros take a break. They take it five days. They rest two days. This may help. The data is thin. Pick what fits you.
What should I track? Track sleep. Track mood. Track focus. Track gym work. Use a note app. Check it each week. Then judge what works.
How fast will I feel it? Some feel it in a day. Some feel it in a week. Some feel it in a month. Be fair to the test. Give it 30 days at least.
What if I feel off? Stop the pill. Drink water. Rest the day. Then call the doctor. Do not push past odd signs.
Where should I buy it? Buy from the brand site. Skip third-party stores. Skip cheap deals. The risk is fake gear. Stick with the names ranked here.
The Verdict
If you are buying methylene blue to follow Gary Brecka’s biohacker protocol literally — USP grade, public COA, 10 mg microdose — NooBlue Methylene Blue Capsules is the clear winner at $0.58 per dose. If you want maximum bioavailability and the budget allows it, Troscriptions Just Blue is the premium sublingual pick at $2.33 per dose. Budget buyers should choose NooBlue Liquid at $0.50 per dose rather than the unverified Amazon brands — the price difference is trivial and the COA difference is everything.
