You can't out-supplement your own biology.
You can switch it back on.
The answer isn't more. It's activation.
Most supplements work the same way: adding something to fix a problem. And we're conditioned to keep seeking outside of ourselves for answers, one more capsule, one more fix, always somewhere out there. But the systems that protect and renew you are already running inside. They don't need more added to them. They need switching back on.
Meet our master strain, Tetraselmis chuii.
phytovive 01 // source is formulated around one hero ingredient: this microscopic marine microorganism, honed to a single phenotype, DNA-mapped for purity and consistency, and cultivated in clinical-grade, closed-loop systems.
It uniquely activates two of your body's master switches at once, the pathways behind your defense and your renewal.*
How it does that starts with a simple question, why do we age at all?
Tetraselmis chuii, our master strain, under the microscope
Vitality begins with balance.
Simply living, breathing, moving, metabolizing, produces reactive molecules called free radicals. Your body evolved its own system to keep them in check. But modern life tilts the scale: pollution, stress, processed food and too little sleep build faster than your defenses can clear, and the balance tips toward oxidative stress. It's one of the upstream drivers of how we age.
Your biology isn't failing. It's outpaced. And a system that's outpaced doesn't need replacing. It needs reactivating.

One antioxidant vs one free radical. It's a losing battle.
Every antioxidant reaches your cells one of two ways: added from the outside, or made within. Almost everything on the supplement shelf is the added kind. And when we consume an antioxidant molecule, it neutralizes a single free radical, one for one, then it's spent. Bring in another, and another, like carrying water one bottle at a time, while your cells throw off free radicals all day. Adding from the outside can help. But it can never keep pace.
Your body already has a spring.
Your own defenses are made from within, and they aren't used up. One enzyme does its job, releases, and does it again. A spring, not a bottle. The source was never in the bottle. It's in you. So phytovive doesn't add. It activates.*
Learn about endogenous vs exogenous- Exogenous
- from the outside, every antioxidant you add. Does one job, then it's spent.
- Endogenous
- from within, the defenses your body makes itself. Renewable, never used up.
One signal. Your whole renewal system comes online.
Your cells are run by master switches, control genes that bring whole systems online at once. phytovive's master strain flips two of them. In a human trial it activated both: NRF2, which commands your defense, and SIRT1, which commands your renewal.*
Master switch · 01
NRF2
Commands your defense
Puts your own antioxidant enzymes to work, made on demand, exactly where they're needed.
Master switch · 02
SIRT1
Commands your renewal
A sirtuin tied to cellular renewal, metabolism and healthy aging, helps your cells repair and keep order.
Activate the switch, and the effects cascade.
NRF2 and SIRT1 sit above whole networks of your own biology. Activate them, and the effect reaches across your body at once. Here's how it happens.
One signal in.
phytovive's marine strain acts as a signal. It activates, it doesn't add.
Two master switches flip.
NRF2 and SIRT1 activate together, measured in a human trial.
Your own defenses come online.
Your body makes its antioxidant enzymes on demand, and its cells repair and renew.
Your whole system, online.
Not one molecule doing one job. Your whole renewal system, back online.*

A randomized, double-blind, placebo-controlled human trial (Cocksedge et al., 2025) found phytovive's marine strain up-regulated NRF2 and SIRT1 gene expression, alongside several of the body's own antioxidant-enzyme genes. The first human trial of its kind.*
How we read the evidence, tier by tier
Tier 1 · Proven in humans. The randomized controlled trial above, measured directly in participants.
Tier 2 · A broader body of science. That human result sits on two decades of supporting laboratory and animal work on the strain's antioxidant activity.
Tier 3 · The frontier. A young field we're all-in on. As the research deepens, into recovery, mitochondrial function and how far this reaches, we'll share it openly and in plain language.
*Measured in a randomized, double-blind, placebo-controlled human trial (Cocksedge et al., 2025). Gene-expression outcomes. Individual results vary.
The science has a product.
One master strain. One protocol. Your own biology, reactivated.
