This isn't a story about a supplement. It's a story about what happens when your body says no, and what I found when I went looking for a way back.
I've been an entrepreneur since I was a kid. Started companies, sold companies, started new ones. At 43 I was living the life I'd chased: several businesses, high speed, even my own helicopter. I thought the pace was the price of success, and that I could afford to pay it.
I was wrong.
The year everything crashed.
It came fast. First I lost the hearing in one ear, then a pressure across my chest that wouldn't let go. The doctors found nothing wrong, but nothing felt normal. I was 43 and felt 60. And with the exhaustion came something I didn't have words for then: anxiety, and after it, depression.
I was on sick leave for a year, with treatment and medication. Had no energy for anything, didn't want to see people, couldn't look anyone in the eye. My wife says I was very quiet at home. What had been easy was heavy, and what had been fun no longer meant anything.
The book that changed the game.
The medication also meant I wasn't allowed to fly. After six months I realized that was what I missed most: the one place where my head used to go quiet. I wanted to get back there, and I wanted to get back to myself. So I did what I've always done when I don't understand something: read everything there was. It was 2019, and longevity was still an unknown word in Sweden.
Then I found David Sinclair's Lifespan, which had just come out. I read it several times. What stuck wasn't the promise of a longer life but a simpler idea: aging is a process, and processes can be reversed. The energy I'd lost wasn't something I had to live with. It could be won back.
Four compounds and three months.
Sinclair writes about NAD⁺, the molecule every cell needs to turn food into energy, and how levels decline with age. He writes about the compounds he takes himself to keep them up. I started with four of them: NR, TMG, pterostilbene and grape seed extract.
Nothing happened the first week. Nor the second. But after about two months the energy was back. A month later my head was clear. And with the energy came something I hadn't had in years: the desire to take care of myself. I started training, cold plunging, meditating every day.
The energy came back. The days held all the way through.
Clear head. First workout in many years.
Cold plunges, meditation, training. And the compounds, every day.
The four compounds were the spark. They gave me something I hadn't had in a long time: the energy to take care of myself. That's when the journey back began. And the more I took care of myself, the better everything else got: work, family, mood.
From the spark to Nexus.
When I was well again I went back to what was left of my businesses. But I didn't stop reading. For three years I went deeper into the research on NAD and aging, and quietly built something I'd missed myself: a supplement with exactly the compounds that had brought me back, in the doses the studies use. In 2023 I launched Lifeseeds and Nexus.
The four compounds have since become seven. NR to raise NAD⁺, luteolin to protect it from breakdown, and five more that support the process, in one capsule. Nexus is now in its third version.
Today, seven years later, I'm 50 and have never been in better shape, physically or mentally. I live as a biohacker, testing and measuring, and I've been invited to talk about it on TV4 and Swedish Radio, on stages and at longevity conferences. But that's not what I'm most proud of.
What I'm most proud of.
It's the feedback. People who write that they recognize themselves, not because they're ill, but because they're tired in a way sleep doesn't fix. And that it turned around.

What I can promise, and what I can't.
My personal goal is simple: stay healthy until the treatments now on the horizon arrive, the ones that can truly turn back the clock. It's the same goal I have for you.
I can't promise you'll feel what I felt. The effect builds gradually and looks different from person to person. What I can promise, based on clinical studies in humans, is that your NAD⁺ level rises, and that you get 90 days to find out what it looks like for you. If you don't notice a difference, we'll refund you.
