USP-grade methylene blue

Clearer focus. Sharper thinking. Steady mental energy.

Methylene blue was first made in 1876 and has been used in medicine for more than 100 years. Ours is USP grade, a precise 10mg in every capsule, with human brain research behind the ingredient.

What one capsule a day does

Clear, steady focus from the energy your brain makes

Your brain burns about a fifth of your body's energy. Methylene blue supports the way brain cells make that energy, in their mitochondria, and one capsule gives you a precise 10mg every day.

How methylene blue works

More energy. Clearer thinking.

Memory and attention, measured

In a 2016 University of Texas trial, healthy adults took one dose of USP-grade methylene blue or a placebo. An hour later the methylene blue group got about 7% more memory answers right, and brain scans showed more activity in the areas for attention and short-term memory.

Rodriguez et al., 2016 · 26 adults · one 280mg dose (about 4mg/kg)

A precise 10mg, every capsule

No dropper to read, no dilution and no blue-stained glass. Swallow one capsule and you've had your full 10mg.

USP grade · 10mg per capsule

Caffeine-free focus

Mental energy and clarity support with no caffeine and no stimulants, so there's nothing to crash from at 3pm.

Two actives: methylene blue and vitamin C

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.

60 capsules · 1 a day

What to expect

Your first three months

Methylene blue works best as a daily habit. Here's what regular takers describe at 1 capsule a day.

  1. Weeks 1–2

    Clearer mornings

    Some people notice sharper thinking within days. Blue-green urine is expected.

  2. Weeks 3–4

    Focus feels steadier

    Regular takers describe less brain fog after a few weeks of daily use.

  3. Month 2

    Bottle one, done

    60 capsules last 60 days. By now it's simply part of your day.

  4. Month 3+

    Your new baseline

    Clear, steady days, one capsule at a time. Three bottles cover six months.

Why USP grade matters

Pharmaceutical grade, to the exact milligram

Methylene blue is also sold as a lab stain and an aquarium treatment, which aren't made for people. Ours is USP grade, made to the United States Pharmacopeia standard for identity, strength and purity.

Everything else is simple: a little rice flour and a vegetable cellulose capsule. There's no proprietary blend, so you know exactly what you take each day.

The research

Studied in the human brain

Methylene blue's effect on brain energy and memory has been studied for decades, in people and in the lab. Here is the clearest human result, then three more.

Randomised, placebo-controlled trial · 2016 · 26 adults

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

Researchers at the University of Texas gave healthy adults one dose of USP-grade methylene blue (280mg, about 4mg/kg) or a placebo, then scanned their brains during memory and attention tests. The methylene blue group got about 7% more memory answers right, while the placebo group didn't improve.

In healthy adults, an hour after one low oral dose, brain scans showed stronger connections between the regions that link perception and memory, compared with placebo.

How to take it

One capsule, once a day

  1. Take 1 capsule a day, or as directed by your healthcare professional. That's the full 10mg.
  2. Take it at the same time each day. A steady routine is easy to keep, and one bottle lasts two months.
  3. Expect blue-green urine. It's the dye leaving your body, and it's expected.

How long your order lasts, at 1 capsule a day

Don't take it if you

  • take SSRIs, SNRIs, MAOIs or other serotonergic medicines. Methylene blue can cause serotonin syndrome with them
  • have G6PD deficiency
  • 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.

What's inside

Two active ingredients. Nothing else.

Methylene blue, or methylthioninium chloride, was first made in 1876. Each capsule holds 10mg of the USP grade and 10mg of vitamin C, filled with a little rice flour into a vegetable cellulose capsule.

FAQ

Questions, answered

Still deciding?

info@eternalelixir.com.au

What is methylene blue?

A compound first made in 1876 as a dye, and used in medicine for more than 100 years. Today it's studied for how it supports energy production in brain cells. Ours is USP grade, with 10mg in every capsule.

When will I notice a difference?

Some people notice sharper thinking within days, and others after a few weeks. Give it a few weeks of daily use at 1 capsule a day before you judge it.

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, 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.

What if it's not for me?
