For those who care about what goes into every capsule.EGT once cost up to $1 million per kilogram.

We developed the biotechnology to change that. And once you can make something for less, you have a choice: make it cheaper, or make it better.

We chose better. Every GeneIII capsule carries 30 mg of our own L-Ergothioneine, made to a 99.99% purity specification. We don’t compromise that standard to reach a lower price point.

Because making the molecule was never the finish line. The more scientists study ergothioneine, the more interesting it gets, so we invested in studying ours: eight completed human studies on GeneIII® EGT, with more underway. We believe a supplement should be judged by what the evidence supports, not by what its ingredients promise.

We do that work alongside people who have spent their careers on it, including Professor Barry Halliwell, a world-renowned expert in oxidative stress and antioxidant research.

And we keep our standards where you can see them: independent third-party testing, documented purity specifications, and FDA GRAS Notice 1270, which received a “no questions” response.

For those who care about what goes into every capsule.

There's an antioxidant your body treats differently from every other one - and it can't make a single molecule of it.

It's called L-Ergothioneine. EGT, for short. Mushrooms make it. A few other foods carry traces of it. Humans never developed the machinery to produce it, so every bit you have came in through what you ate.

Here's the part that made scientists pay attention. Most antioxidants pass through you. They do their job, or they don't, and they're gone. Not this one. Your body has a transporter (OCTN1) whose only known job is to pull ergothioneine into cells and hold on to it. It builds up exactly where oxidative stress hits hardest: brain, eyes, liver, kidneys, skin, heart. And it stays there for weeks, sometimes months.

Your body doesn't build a door for something it doesn't need.

Found in 1909. Understood in 2005. Since 2021, GeneIII has made L-Ergothioneine by patented precision fermentation at 99.99% purity - one capsule carries about as much EGT as 300 to 500 grams of reishi.

Your body can’t make L-ergothioneine. Yet it has a specialized transporter that actively moves it into your cells.

In nature, EGT is found most abundantly in certain mushrooms. But most people don't get enough from diet alone.

You don’t feel aging at first. Because it doesn’t start on the surface, it starts at the cellular level.

Every day, your body is exposed to oxidative stress a natural process that can gradually affect DNA, proteins, and mitochondria.

When you’re younger, your body keeps this in balance. But over time, those protective systems become less efficient.

And that’s when small, silent changes begin to add up. This is why aging often feels like it appears “suddenly” when in reality, your cells have been dealing with it for years.

One molecule researchers are paying closer attention to is L-ergothioneine.

It’s a unique antioxidant your body actively transports into cells especially in areas more vulnerable to long-term stress, like the brain.

Its role isn’t to stop aging, but to help support how your cells manage oxidative stress over time.

Because what you feel is only the result. What matters most… happens much earlier.

Networking can show you what’s working, what to avoid, and open doors you didn’t even know existed and that’s how you find better opportunities.

What if the changes you haven’t felt yet are already happening?

Long before anything shows on the outside, silent processes are running in the background — oxidative stress gradually affecting your DNA, proteins, and mitochondria.

For a while, your body handles it. It repairs. It adapts. It keeps up.

But over time, those repair systems become less efficient. The damage accumulates. And one day, aging feels like it appeared out of nowhere — when really, it’s been building for years.

This is why what you do at the cellular level matters more than most people realize.

Ergothioneine is one compound researchers are paying close attention to. It’s a unique antioxidant your body actively transports into cells — particularly in the brain and mitochondria, where long-term cellular stress tends to hit hardest.

Not to reverse aging. But to support the systems that age first.

Because the best time to support your cells isn’t when you notice something. It’s before.

Fatigue isn’t always just simply “feeling tired.”

As we age, the cellular systems that produce energy can become less efficient, while everyday oxidative stress adds pressure from the outside in.

This is why researchers have taken interest in ergothioneine, an antioxidant found primarily in mushrooms. What makes it unusual is that the body has a dedicated transporter to carry it directly into cells, including where energy production happens.

Early research is exploring its potential role in supporting cellular energy systems and healthy aging more broadly.

Long before any noticeable changes, quiet shifts are already happening in the brain, driven by oxidative stress and gradual cellular wear.

These processes can affect neurons, mitochondria, and the systems responsible for energy and communication. Over time, small changes accumulate.

This is why researchers are increasingly focused on early, long-term cellular support.

One molecule gaining attention is ergothioneine. It’s a dietary antioxidant your body actively transports into the brain, where it may help support cells exposed to ongoing oxidative stress. Emerging research continues to explore its role in long-term brain health.

Most people think about their health in hindsight, or put it off for “someday.”

But your future health is shaped by what you do today.

Long before symptoms show up, subtle changes are already happening. Energy production slows. Cells become more vulnerable to stress.

What you do now matters more than you think.
