A Founder's Note

We Made It for People in Their 30s. Our Best Customers Turned Out to Be My Dad's Age.

My girlfriend and I started taking a few blue drops for focus. Then people over 60 became our best customers. Here's why it seems to hit hardest later in life.

Five years ago, my girlfriend Sharon and I tried something new.

A few drops of a blue liquid in our morning water. It's called methylene blue, and it was discovered over 150 years ago.

We just wanted to focus better at work. It helped so much that we started our own brand. We made it for people our age.

We were wrong about who would need it most.

Our best customers turned out to be people my dad's age, and 94% of the 3,500 we surveyed felt results within 3 weeks.*

Below I'll show you why it seems to hit hardest after 60. And what to check if you want to try it.

Five Years Ago, a Few Blue Drops Changed How Sharon Worked

Sharon is one of the smartest people I know. But staying on task was always a fight for her. She'd sit down to work, and her mind would wander off.

She tried a lot of things over the years. None of them felt right.

The blue drops did. She could finally lock in for hours and get her work done.

The part that surprised us most wasn't the focus, though. It was her mood. She was lighter, more positive, more like herself. She still calls it life-changing.

Now she's a bit of a workaholic. I have proof:

For me, it wasn't as dramatic. But on days I need deep focus, it helps me get there.

We figured people our age would love it. So we started our own brand.

We Built a Brand for People Our Age. Then My Dad Started Taking It.

He takes it the same way we do: a few drops in his morning water.

My dad Ron is 66, still works full days, and says he stays focused all afternoon now.

Then something we didn't expect happened. Most of our orders weren't coming from people our age.

They were coming from people like my dad.

Then the stories from people his age started pouring in.

People who'd been stuck in a fog for years. People who were done by 3pm. They told us they had the energy to enjoy retirement again. Time with the people they love. The things they'd put off for years.

So I started digging into why.

Why It Hits Harder After 60: Your Cells' Power Plants Slow Down

Almost every cell in your body holds hundreds, even thousands, of tiny power plants called mitochondria. They turn the food you eat and the air you breathe into ATP. That's the energy behind everything you do.

Your brain is the hungriest customer. It's about 2% of your body weight but uses roughly 20% of your energy.[1]

Here's the problem: when they slow down, your brain is the first place you feel it.[2] With age they make less energy, and they leak more "exhaust" while they work.

Here's what that looks like up close:

Look at the gap between 25 and 55. Older cells have more lost energy to win back. That's my best guess at why people my dad's age feel it more than we did.

It Shows Up as the 3pm Crash, the Fog and the Couch

• A predictable afternoon crash, no matter how much coffee you drink
• Brain fog, rereading things, and losing words mid-sentence
• Less drive to start things, and less stamina to finish them
• Taking days to bounce back after a workout, a round of golf, or a bad night's sleep
• Falling asleep on the couch in the evening, yet still waking up tired

These aren't five separate problems. They're five symptoms of the same one: your cells are making less energy than they used to.

Why More Coffee Only Makes the Crash Worse

Most people try to fix this the obvious way. More coffee. A longer nap. An energy drink when no one's looking.

The problem is that stimulants don't create energy. They borrow it. Caffeine blocks the signal that tells your brain you're tired, but it does nothing for the power plants underneath. That's why the lift fades, the crash comes back harder, and you need a bit more each month to feel the same.

If the real issue is how much energy your cells are producing, then the real fix has to work at that level.

Inside Every Cell Is an Energy Assembly Line, and It Slows With Age

Inside each mitochondrion is a tiny production line called the electron transport chain. Here's how it works:

1. The food you eat is broken down, and its energy is carried as electrons.
2. Those electrons are passed down a chain of four protein "stations," like a bucket brigade.
3. Each handoff pumps particles across a membrane, building pressure like water behind a dam.
4. That pressure spins a microscopic turbine that produces ATP, your cells' energy.

When the handoffs are smooth, you feel it: steady energy, a clear head, and you bounce back quickly.

With age, some of those stations get sluggish. Electrons back up. Less ATP gets made, and more electrons leak out as free radicals. It's like an old factory line: slower output, more sparks.

So researchers asked a simple question: what if you could help the electrons keep moving?

A Blue Liquid Discovered 150 Years Ago May Help Keep the Line Moving

Methylene blue was first made in 1876, and researchers have been curious about it ever since.

Here's why it matters for energy. Methylene blue can accept and donate electrons, switching back and forth between blue and clear. Inside the cell, methylene blue can act as a backup carrier. It picks up electrons where the chain is backed up and passes them down the line.[3]

Here's what that looks like:

It's not just theory. Here's what researchers saw in aging human cells:

Researchers also found that it appears to act most where demand is highest, in the brain regions doing the hardest work at that moment.[4]

That's a very different approach from caffeine. It supports how your cells make energy rather than masking the feeling of being tired.

Then researchers looked inside the human brain.

In a Brain-Scan Study, Memory Scores Rose 7%

In 2016, a team at the University of Texas published a study in Radiology, a respected medical journal.[4]

It was a small study, and it looked at a single serving over a short window, so more research is needed. But it was one of the first times anyone had looked inside a living human brain to see what methylene blue does. Read the full study on PubMed →

That's the science. Now the part most people miss: what's actually in the bottle.

The Catch: Most Methylene Blue Isn't Made for People

Since that study, interest in methylene blue has exploded, and so have the cheap bottles online.

Methylene blue is also an industrial dye and an aquarium product. Much of what's sold online is made for dyes and fish tanks, and many sellers never test it for heavy metals.

Before you buy any methylene blue, know the difference:

We didn't want to sell that, and we didn't want my dad taking it.

So we made our own, to a standard we'd trust for our own family.

The Kind We'd Give My Dad: Heisen Blue

It's called Heisen Blue. It's USP grade, the purity standard for something you put in your body, not a dye standard.

We fill every bottle ourselves in Vancouver, and every batch passes 30+ tests, including heavy metals.

It comes as a 2% solution in a 120ml dropper bottle. Most people add a few drops to a glass of water in the morning. No pills, no powders, no 3pm crash from a stimulant wearing off.

But you don't have to take my family's word for it. Here's what customers say after a few weeks:

Ron H. Is 77. He Just Split 3 Cords of Wood.

Most People Feel It Within 3 Weeks

A brain scan is one thing. What matters is how it feels on a Tuesday afternoon. In a survey of 3,500 Heisen Blue customers, 94% said they felt results within 3 weeks.* Here's what that usually looks like:

One surprise: methylene blue can turn urine blue or green for a while. It's normal, and it's usually the first thing people notice.

If You Try Methylene Blue, Check These Three Things First

The afternoon crash and the fog aren't a character flaw. They're a sign your cells are making less energy than they used to.

Caffeine borrows energy. Methylene blue works on the assembly line that makes it.

But whether you buy from us or not, check these three things before you try any methylene blue:

1. USP grade, not industrial or aquarium grade.
2. Heavy metals tested on every batch, with results the seller will show you.
3. A clear amount on the label, so you know how much is actually in the bottle.

You can hunt down a brand that does all three on your own.

Or take the shortcut: Heisen Blue checks all three, and I personally guarantee it for 30 days.

If you don't feel the difference, email me at info@heisenblue.com and I'll refund every cent myself. Keep the bottle, even if it's opened. You don't risk a thing.
