Why the drops
One dropper gives you a measured 10mg, and you can take less whenever you want to.
Every 1ml holds 10mg of USP-grade methylene blue. Take the full 1ml, or 0.5ml for 5mg, with the dropper.
Add your drops to a glass of water and drink. There's nothing to get down, and each bottle holds 50 servings.
Methylene blue supports cognitive performance and mental clarity by supporting energy production in your cells' mitochondria.
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.
What to expect
One dropper a day, from your first dose to your second bottle.
Add 0.5 to 1ml to a glass of water and drink. 1ml is the full 10mg serve. Your urine may turn blue-green: that's the dye leaving your body, and it's expected.
Take it at the same time each day. Some people notice sharper thinking within days.

Methylene blue, or methylthioninium chloride, was first made in 1876. Every 1ml of our drops holds 10mg of the USP grade, dissolved in purified water to make a 1% solution.

Good to know. Your urine may turn blue-green. That's the dye leaving your body, and it's expected. Store in a cool, dry place, out of reach of children.
How it works
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.

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

The 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
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.

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

FAQ
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.
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.
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.
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.
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.
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.
