Why the capsules

Your brain runs on energy. Methylene blue helps make it.

One capsule gives you a precise 10mg, every day, with nothing to measure.

Precise every time

Each capsule holds 10mg of USP-grade methylene blue. You get the same amount every day, with no dropper to read.

Nothing to measure

No dropper, no dilution, no taste. Swallow one capsule and you're done. The bottle travels well, too.

Focus and mental clarity

Methylene blue supports cognitive performance and mental clarity by supporting energy production in your cells' mitochondria.

Two months a bottle

At 1 capsule a day, a 60-capsule bottle lasts two months. That's $1.00 a day, or $0.80 when you buy 5 bottles.

What to expect

Your first months, step by step

One capsule a day, from your first dose to your second bottle.

  1. Day 1

    Start your routine

    Take one capsule. That's the full 10mg serve. Your urine may turn blue-green: that's the dye leaving your body, and it's expected.

  2. Weeks 1–2

    Build the habit

    Take it at the same time each day. Some customers notice sharper thinking within days.

    “Within days I noticed sharper thinking and better memory.”Alexandra H.
  3. Weeks 3–6

    Feel it settle in

    Some customers say focus and clarity feel steadier after a few weeks. Give the routine time before you judge it.

    “Been on the capsules for a few weeks now. Main thing I notice is waking up with less brain fog.”Lukas Duffy
  4. Month 2

    Bottle one, done

    At 1 capsule a day, 60 capsules last 60 days. Customers who keep going often make it part of their day.

    “First methylene blue product I actually stuck with.”Riley B.
  5. Month 3 and on

    Keep the momentum

    At 1 capsule a day, 3 bottles last 6 months and save 15%. 5 bottles cost the same as 4.

Two active ingredients. Nothing else.

How it works

It works where your cells make energy

Your cells make ATP, their main energy source, in their mitochondria by passing electrons along a chain of proteins. Methylene blue can act as an alternative electron carrier in that chain, supporting ATP production, including in brain cells.

Methylene blue has been used in medicine for more than 100 years. Each capsule gives a consistent 10mg, so your routine stays the same day to day.

Is it right for you?

Read this before you start

Methylene blue isn't for everyone. Check this list first, and talk to your doctor if you're unsure.

  • take SSRIs, SNRIs, MAOIs or other serotonergic medicines. Methylene blue can cause serotonin syndrome with them

  • are pregnant or breastfeeding
  • are under 18

Also good to know

  • Talk to your doctor first if you take any prescription medicine or have a medical condition.
  • Don't combine it with saffron or ginseng supplements, including our Brain, Mood & Sleep and Daily Energy stacks.
  • Don't use if the seal is broken or missing.

The research

Decades of brain-energy research

Researchers have studied methylene blue's effect on brain energy and memory for decades, in people and in the lab. Here's what four key papers found, with the dose each one used.

Human trial · Randomised, placebo-controlled · 2016

One dose. 7% more right answers, an hour later.

Researchers at the University of Texas gave 26 healthy adults a single dose of USP-grade methylene blue (280mg, about 4mg/kg) or a placebo in a randomised, double-blind trial. Then they scanned their brains while they worked through memory and attention tests. An hour later, the methylene blue group got about 7% more memory answers right, while the placebo group didn't improve. Their brain scans showed the difference too, with more activity in the areas that handle attention and short-term memory.

Methylene blue modulates functional connectivity in the human brain

Rodriguez et al., Brain Imaging and Behavior, 2017 · healthy adults · one low oral dose

An hour after one low dose, brain scans showed stronger connections between the regions that link perception and memory, compared with placebo.

Scientific review

Neurometabolic mechanisms for memory enhancement and neuroprotection of methylene blue

Rojas, Bruchey & Gonzalez-Lima, Progress in Neurobiology, 2012

Reviews how low-dose methylene blue cycles electrons in the mitochondria and describes a dose response where low and high doses have opposite effects.

FAQ

Questions, answered

What's in each capsule?

10mg of USP-grade methylene blue and 10mg of ascorbic acid (vitamin C), with rice flour as a filler, in a vegetable cellulose capsule. There are 60 capsules in each bottle.

How do I take it?

Take 1 capsule a day, or as directed by your healthcare professional.

How long does a bottle last?

At 1 capsule a day, as the label directs, a bottle lasts 60 days. Two bottles last four months, three last six and five last ten.

Will it turn my urine blue?

It can. Methylene blue can temporarily turn urine blue or green after you take it. That's expected: it's the dye leaving your body.

Who shouldn't take methylene blue?

Don't take it with SSRIs, SNRIs, MAOIs or other serotonergic medicines, if you have G6PD deficiency, if you're pregnant or breastfeeding, or if you're under 18. Don't combine it with saffron or ginseng supplements. Talk to your doctor first if you take any prescription medicine. See the full safety list.

Should I choose the capsules or the drops?

Choose the capsules if you want the same 10mg every day with nothing to measure. Choose the drops if you'd like to adjust the amount, from 0.5ml (5mg) to 1ml (10mg). Both cost about $1.00 per 10mg.

How fast is shipping, and what does it cost?

We dispatch fast. Metro delivery usually takes 3 to 5 business days and regional delivery 5 to 7. Shipping is free over $100. Below that, standard shipping is $10. This item is shipped separately and arrives in its own package, and Express Post isn't available for it.
