Just Blue methylene blue is a 16 mg troche made by Troscriptions, and this review covers the formula, the dose math and how to buy it as of Oct 2026. Each troche dissolves in your mouth, the pack holds four scored troches, and Troscriptions now sells all its products, Just Blue included, exclusively through healthcare practitioners. If you want a simpler daily format, NooBlue Methylene Blue Gummies are our pick: NooBlue makes these gummies, and it is our pick because one 10 mg gummy covers the serving with no blue mouth.
Quick answer: Just Blue is a physician-formulated troche for people who want a low, flexible dose and do not mind the blue tongue that troches cause. NooBlue Methylene Blue Gummies are our pick for daily use instead: one 10 mg gummy, 60 per pack, $49.99, about $0.08 per mg, no blue mouth, shipped worldwide by NooBlue.

Just Blue methylene blue at a glance
Here is the side-by-side. Just Blue is a troche, which is a small tablet that dissolves between lip and gum, so the dose enters through the mouth. NooBlue ships direct worldwide, which changes how you buy as much as what you buy.

Both products sit in the low-dose range people use for daily routines. The differences that matter in practice are format and how the purchase happens, and the rest of this review takes each in turn. For the wider market, the 2026 reviews hub covers brands we have not touched here.
Just Blue formula and dose
Each Just Blue troche carries 16 mg of methylene blue. The troche is scored into quarters, so you can break off roughly 4 mg at a time, which makes the pack flexible: Troscriptions counts up to 16 doses per four-troche pack if you work in quarters. The base is a troche matrix that dissolves in the mouth rather than a capsule you swallow, so absorption starts in the oral cavity.
That flexibility is the honest appeal. If you want 4 mg on some days and a full 16 mg on others, the scored tablet lets you dial it without owning two products. The trade is convenience: you handle a small blue lozenge, wait for it to dissolve, and accept the colour change the brand itself documents. NooBlue’s daily mg guide explains how low daily servings sit in the wider dosing picture.
The formula is minimal by design: methylene blue, and the excipients that make the troche hold together and dissolve. There is no caffeine or nicotine here. Just Blue is methylene blue only, which keeps it clean for stacking but leaves the troche base and the blue colour as part of the experience.
Just Blue methylene blue pack size and value
A pack holds 4 troches at 16 mg each, so a pack carries 64 mg in total. Troscriptions now sells only through healthcare practitioners, so we do not give a store price or cost per mg for it.
The NooBlue gummies are $49.99 for 60 gummies at 10 mg each: 600 mg per bottle, about $0.08 per mg. The capsules run about $0.13 per mg and the 1% drops about $0.06 per mg. If you take a daily 10 mg serving, a single $49.99 bottle covers two months for about $0.83 per serving.
Value is not only price. The troche buys dose flexibility and a physician-formulated minimal stack. The gummy buys a two-month supply per bottle and no blue mouth. Where those trade off depends on how you take methylene blue, which is why the price-range explainer is worth a read before you commit.
How to buy Just Blue
Troscriptions states that its products are now available exclusively through healthcare practitioners. In practice, that means you may need to order through a practitioner who stocks the brand, and some third-party retailers still list Just Blue. Stock and channel can change, so check availability before you plan a routine around it.
That is the friction point. A practitioner-only model suits patients already working with one, but it adds a step for everyone else: no direct checkout, no subscription you can manage yourself, and retail listings that may or may not carry the current pack. NooBlue sells every format direct from its own store, with free worldwide shipping on orders over $100.

What to know before taking a troche
The troche format has quirks worth knowing before you buy. Troscriptions’ own FAQ says a troche turns the mouth blue and the discoloration lasts between 2 and 24 hours. That is a cosmetic change, not a safety one, but it is visible in photos, meetings and dentists’ chairs, and it is the single most cited drawback of lozenge-style methylene blue.
Taste and texture matter too. A troche sits in the mouth for minutes as it dissolves, and the base has a distinct flavour profile some users notice. If you dissolve a quarter troche, you halve the wait but still get the colour. Urine can also turn blue or green with any oral format, which is expected and temporary.
NooBlue gummies sidestep the mouth issue: chew and done, with no blue tongue afterwards. The gummies contain vitamin C, which can shift methylene blue toward its colourless form, and the format simply does not leave a blue mouth. Capsules are another route.
They are swallowed whole, so they never touch your teeth. Our gummies review compares every gummy brand we have checked.
Just Blue vs NooBlue
NooBlue sells three formats: the gummies, the 5 mg capsules and the 1% drops. Here is the direct comparison on the points that decide a purchase.
| Factor | NooBlue gummies | Just Blue |
|---|---|---|
| Serving | 1 gummy, 10 mg + vitamin C | Quarter to full troche, about 4 to 16 mg |
| Pack | 60 gummies (2-month supply) | 4 troches (up to 16 quarter-doses) |
| Price | $49.99 | Through practitioners |
| Cost per mg | About $0.08 | Not calculable |
| Blue mouth | No | Yes, 2 to 24 hours per brand FAQ |
| Buying | Direct, worldwide, free shipping $100+ | Practitioner channels. Some retailers |
We pick the gummies for daily use. NooBlue Methylene Blue Gummies avoid the blue mouth that troches and drops cause and ship direct worldwide. The CTLA ingredient report for the methylene blue sits on the product page, covering the raw ingredient lot (cadmium 0.010 ppm. Arsenic, mercury and lead each below 0.001 ppm, ingredient-level test), so you can see the numbers before you buy.
The troche keeps one genuine edge: dose granularity down to about 4 mg in a dissolvable format. If your routine depends on micro-titrating, Just Blue does that and the gummy does not. For a fixed daily 10 mg, though, the gummy wins on pack size and the absence of a blue tongue, and the product page has the current details.
Who Just Blue suits (and who should look elsewhere)
Just Blue suits three kinds of buyers. First, patients already working with a practitioner who stocks Troscriptions, where the ordering friction disappears. Second, dose tinkerers who want to move between about 4 mg and 16 mg with a scored tablet and prefer not to own two products. Third, minimalists who want methylene blue alone, no caffeine, no nicotine and no extra actives, in a format that starts absorbing in the mouth.
You should look elsewhere if any of the following describes you. If you want a fixed daily serving with nothing to split, the NooBlue gummy or capsules suit you better. If you dislike blue teeth and long dissolves, a swallowed capsule avoids the mouth entirely.
And if you want to order tonight without a practitioner intermediary, direct-from-brand or retail listings are simpler. The NooBlue legitimacy review covers what buying from us looks like.
FAQ
Is Just Blue methylene blue safe?
Troscriptions lists pregnancy, breastfeeding, G6PD deficiency and serotonergic drugs such as SSRIs and SNRIs as contraindications, and the product is third-party lab tested. Any methylene blue can colour urine blue or green. If you take any prescription medicine, including MAOIs or other serotonergic drugs, talk to your doctor before adding it.
Under 18, pregnant or breastfeeding? Clear it with your clinician first. The same applies if you have G6PD deficiency.
How much methylene blue is in Just Blue?
Each troche contains 16 mg of methylene blue. The tablet is scored into quarters, so a quarter works out to about 4 mg, and Troscriptions counts up to 16 doses per four-troche pack on that basis. If you take a full troche, the pack lasts four servings. The dose sits in the low range commonly used in daily energy and focus routines rather than high-dose protocols.
How do you take Just Blue?
You place the troche between lip and gum, or under the tongue, and let it dissolve. Break along the score lines for a quarter, half or full dose. A quarter is about 4 mg.
The troche is designed to dissolve in the mouth. Expect your mouth to turn blue while it dissolves and for some hours afterwards, per the brand’s own FAQ, and note that urine can also shift colour.
Can you still buy Troscriptions Just Blue?
Yes, with a caveat. Troscriptions says its products are now available exclusively through healthcare practitioners, so the primary route is a practitioner who carries the brand. Some third-party retailers still list Just Blue, and stock levels change. If you want a no-intermediary purchase, the NooBlue store ships direct worldwide, and the brands hub lists every brand we cover.
Does Just Blue stain your teeth?
The troche colours the mouth, teeth and tongue blue while it dissolves, and Troscriptions’ FAQ puts the discoloration window at 2 to 24 hours. Troscriptions suggests rinsing with diluted vinegar and then a baking soda solution 5 to 10 minutes after the troche has fully dissolved to speed up fading. If a blue mouth is a dealbreaker for work or photos, capsules skip the issue because you swallow them, and NooBlue gummies avoid the blue mouth and tongue that drops and troches cause.
Just Blue vs Blue Cannatine: what is the difference?
Both are Troscriptions troches, but the formulas differ. Just Blue is methylene blue only, at 16 mg per troche, for people who want the single ingredient. Blue Cannatine stacks methylene blue with caffeine, nicotine and hemp, so it behaves more like a layered nootropic troche and carries those ingredients’ considerations too. Choose Just Blue for a clean single-ingredient dose and Blue Cannatine if you want the combined stack in one dissolvable tablet.
The bottom line
Just Blue is a well-specified troche: 16 mg per scored tablet, physician formulated, third-party tested, four troches per pack. Its real constraints are the practitioner-only channel, the small pack and the documented 2 to 24 hour blue mouth. For a daily serving without the mess, NooBlue Methylene Blue Gummies are our pick, with NooBlue shipping direct worldwide.
Using methylene blue safely
Methylene blue is generally well tolerated at low servings, but a few groups should take care. Do not combine it with SSRIs, SNRIs, MAOIs or other serotonergic medicines without medical guidance, because of serotonin syndrome risk. Avoid it if you have G6PD deficiency.
It is not for pregnancy or breastfeeding, and not for anyone under 18. Any oral format can turn urine blue or green, which is expected and temporary. Talk to your doctor before starting, especially if you take prescription medicine of any kind.
