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.
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.

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.

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.

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.
