The oldest life on earth, and what it still does for us.
The marine microorganisms that first filled the sky with oxygen, and why they matter for longevity now.
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.
One strain, honed
phytovive is built on a single marine microorganism, Tetraselmis chuii, our master strain. Not a blend, not an extract, not an isolate: 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.
