The oldest life on earth, and where it leads.
The marine microorganisms that first filled the sky with oxygen, why they matter for longevity now, and where the science goes next.

Before there were plants, before there were animals, before there was breathable air at all, there were marine microorganisms. For billions of years they were the whole of life on earth, and the reason the rest of it became possible.
The first breath
Roughly two and a half billion years ago, tiny photosynthetic organisms in the ocean began releasing something new into the atmosphere: oxygen. Slowly, across an unimaginable stretch of time, they filled the sky with it. Every breath you take traces back to them. Life, quite literally, perpetuating life.
Built for a harder world
Living in sunlit water is a beautiful existence and a brutal one. Intense light and abundant oxygen are precisely the conditions that generate free radicals, and an organism bathed in them all day has to defend itself or perish. So these microorganisms evolved some of the most robust internal antioxidant machinery in the natural world. They didn't outsource their protection. They became extraordinarily good at making their own.
Our master strain
At the heart of source is Tetraselmis chuii, our master strain: the whole organism, cultivated to a single phenotype and DNA-mapped, so that what's inside the capsule is precise and consistent every time.
An organism that mastered oxidative stress at the origin of life, alongside a modern body learning to do the same. That's what we mean by returning to the source.
Beyond a supplement
A capsule is where you meet phytovive. It isn't where the story ends. Underneath the product is a simpler idea: that marine microorganisms, properly understood, can be a platform for longevity science. One organism, cultivated with precision and studied properly, can express more than one benefit and support more than one formulation over time. source is the first of a planned suite, not the whole of it.
Why the ocean
The marine world is the oldest and least-explored library of biochemistry on the planet. Organisms that solved the problem of oxidative stress billions of years before we existed have a great deal to teach a modern body. We think the next chapter of healthy-aging science comes from the water.
Built to last
That ambition asks for patience and rigour: real cultivation standards, real research, real evidence. We would rather build a science company slowly than a marketing company quickly. The strain is the asset, and everything else follows from taking it seriously.
