Frequently asked questions
What are the potential benefits of Methylene Blue?
Methylene Blue may help mitochondria produce ATP, the cellular energy brain cells use to communicate, learn, and form memories. This may support memory, focus, mental clarity, and mental stamina.1 2 6
In a small randomized study of healthy adults, one dose increased activity in brain regions involved in attention and short-term memory and was associated with 7% more correct responses during memory retrieval.5 Its use for cognitive performance and longevity is off-label, and long-term evidence is still emerging.
Will Methylene Blue stain my teeth?
Intact capsules are swallowed whole, so Methylene Blue does not come into direct contact with your teeth or tongue the way drops and troches do that will typically stain the teeth and mouth. As long as you do not chew, open, or separate the capsule, no blue mess!
Do not be alarmed if your urine temporarily turns blue or green as the medication leaves your body. This is an expected effect of Methylene Blue and usually resolves after your dose clears.
Why does dose matter so much with Methylene Blue?
Methylene Blue doesn’t follow the usual “more is better” rule most supplements do. It has a hormetic, or biphasic, dose-response: at low doses it acts as an electron donor that supports mitochondrial energy production, but at higher doses that same chemistry flips and it starts pulling electrons away instead, becoming a pro-oxidant that works against the mitochondria it was just supporting.7 This is one of the single most important things to understand about this compound, and it’s exactly why we treat dosing as a clinical protocol with ongoing guidance, not a bottle you’re handed with a suggested range and no oversight.

Take Methylene Blue 3x per week, or according to the schedule provided by your AgelessRx provider. If prescribed, a US-licensed medical provider will provide a tailored dosage schedule and specific treatment instructions with your care plan.
Important safety information and common side effects
One of the most common side effects of Methylene Blue is blue urine, which is a normal reaction and not cause for alarm. Feces, saliva, and sweat may also be temporarily discolored with a blue tint. Most people clear the medication from their system within 4-6 hours, or up to 24 hours.
Some people may also experience sun or UV sensitivity while taking Methylene Blue. Be cautious when spending time in the sun, even artificial sunlight, and go inside if necessary.
Other common side effects include nausea, vomiting, stomach pain, diarrhea, loss of appetite, anxiety, and urinary irritation.
Most side effects are mild and go away on their own within a week or two. Taking Methylene Blue with a full glass of water and a meal may help minimize the chances of side effects.
Methylene Blue should not be used by anyone with a history of G6PD deficiency, or anyone who has or has had renal dysfunction.
Do not use Methylene Blue if you are currently taking a medication that affects serotonin, such as antidepressants like SSRIs and MAOIs, or SARIs like Trazodone, if you are pregnant or breastfeeding, or plan to become pregnant or breastfeed while taking Methylene Blue.
Though rare, allergic reactions to Methylene Blue are still possible. If you notice any shortness of breath or swelling around your face, tongue, or throat after using Methylene Blue, stop use and contact emergency services right away.

What is Methylene Blue?
(meth-uh-leen bloo)Your brain is one of the most energy-demanding organs in the body.8 Its mitochondria turn nutrients into the fuel brain cells need to communicate, form memories, and stay focused. With age and stress, that process can become less efficient.2
Methylene Blue may help keep electrons moving through the mitochondrial energy chain, supporting ATP production and giving neurons more of the energy they need to work well.6 7
The dose-response curve that changes everything. Low dose: supports mitochondrial energy. High dose: works against it.7

The science of Methylene Blue
Methylene Blue acts as an electron carrier in the mitochondrial electron transport chain, bypassing dysfunctional segments to sustain ATP production–part of why it has an outsized effect on already-stressed mitochondria rather than healthy ones.1
But its effect is strictly dose-dependent. At low doses, it may support energy production and reduce oxidative stress, while higher doses may reverse that effect entirely, turning the same molecule into a pro-oxidant that drives the very stress it was preventing.7
There’s no benefit in more, only a narrow window where it works, and a wide range above it where it works against you. Getting the dose right, under real oversight, is the difference between a compound that supports your mitochondria and one that silently undermines them.

Frequently asked questions
No. Methylene Blue is FDA approved to treat acquired methemoglobinemia, a condition in which the blood cannot carry oxygen effectively.11 Oral compounded Methylene Blue is not FDA approved for cognitive performance, healthy brain aging, or longevity, though several studies suggest these benefits.6 Methylene Blue may be prescribed off-label when a licensed provider determines that it is appropriate for an individual’s medical history and goals.
Methylene Blue is sometimes described as a nootropic because researchers have studied its potential effects on memory, attention, functional brain activity, and mitochondrial energy.1 5 9 It is a prescription medication rather than a conventional stimulant or dietary supplement. Research in healthy adults is promising, but individual results vary.
Methylene Blue is generally well tolerated at appropriate doses, with side effects typically limited to temporary blue-tinted urine, mild GI discomfort, or sun sensitivity. The interaction that matters most: Methylene Blue should never be combined with serotonergic medications like SSRIs, MAOIs, or SARIs (such as Trazodone), due to a real risk of serotonin syndrome. It’s also not appropriate for anyone with G6PD deficiency or a history of kidney dysfunction.11
Much of the Methylene Blue sold online as a supplement is industrial or laboratory-grade, manufactured for staining or research use, not human consumption, and can carry heavy-metal contaminants never intended to enter the body.10
Pharmaceutical-grade Methylene Blue is manufactured and tested to a human-use standard. With AgelessRx, your Methylene Blue plan includes verified pharmaceutical-grade purity, a dose calibrated to your body rather than a generic suggested range, and a licensed clinician who reviews your health history before you start and can adjust your protocol over time.
If you chewed your capsule and it stained your mouth, tongue, or teeth, try swishing your mouth with lemon juice or vinegar water for 30 seconds, then rinsing. Repeat this step several times if necessary. You should also stay hydrated by drinking water throughout the day.
If Methylene Blue stains your skin or clothes, try scrubbing with the same lemon juice or vinegar water solution, or using a full-strength, skin-safe detergent. You can remove Methylene Blue from objects or surfaces with most commercial stain removers. Please note that there is no reliable method to reduce the appearance of blue urine after taking Methylene Blue. In most cases, urine will not clear until 2-6 hours after your last dose, or up to 24 hours.
