Why the drops
Your brain runs on energy. Methylene blue helps make it.
One dropper gives you a measured 10mg, and you can take less whenever you want to.
Just add water
Add your drops to a glass of water and drink. There's nothing to get down, and each bottle holds 50 servings.
Focus and mental clarity
Methylene blue supports cognitive performance and mental clarity by supporting energy production in your cells' mitochondria.
50 days a bottle
At 1ml a day, a 50ml bottle lasts 50 days, or 100 at 0.5ml. That's $1.00 a day, or $0.80 when you buy 5 bottles.

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. Every 1ml gives a measured 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 bottle?
50ml of a 1% solution: 10mg of USP-grade methylene blue in every 1ml of purified water. There are no other ingredients, and each bottle holds 50 servings of 1ml.
How do I take it?
Take 0.5 to 1ml (5 to 10mg) a day, diluted in water, or as directed by your healthcare professional. The label puts one drop at 500mcg, so that's 10 to 20 drops.
How long does a bottle last?
At 1ml a day, a bottle lasts 50 days, or 100 days at 0.5ml. At 1ml a day, two bottles last 100 days, three last 150 and five last 250.
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 drops or the capsules?
Choose the drops if you'd like to adjust the amount, from 0.5ml (5mg) to 1ml (10mg). Choose the capsules if you want the same 10mg every day with nothing to measure. Both cost about $1.00 per 10mg.
How fast is shipping, and what does it cost?
We dispatch fast from within Australia. 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, and Express shipping ($13) is available at checkout.
