As interest in longevity and cellular health continues to grow, brands and distributors need ingredients
that deliver real differentiation, credible science and meaningful results for consumers. Simply adding
‘antioxidant’ to a label is no longer enough.
TetraSOD® has been developed to meet this shifting need. Derived from the marine microalgae
Tetraselmis chuii, TetraSOD® is a patent-protected, activated phytoplankton ingredient designed to
support cellular health.
Instead of offering a short-term antioxidant hit, TetraSOD® supports the systems that control
resilience, balance and healthy ageing to provide a smarter, longer-lasting and more resilient
response to oxidative stress.
The result is a foundational ingredient for premium, longevity-led formulations.
What exactly is TetraSOD®?
TetraSOD® is produced using our proprietary cultivation and activation technology that enhances the
microalgae’s natural antioxidant activity.
This makes it one of the most concentrated natural sources of superoxide dismutase (SOD), one of
the body’s primary antioxidant enzymes that acts as the first line of defence against oxidative stress.
TetraSOD® delivers more than 30,000 IU of SOD per gram – up to 30x more than any other marine
phytoplankton strain on the market – alongside antioxidant enzymes GPx and CAT, essential fatty
acids, vitamins, minerals, amino acids and protective pigments.
In other words, TetraSOD® isn’t a single isolated compound, it’s a multi-functional ingredient that
offers a naturally balanced nutritional profile. In a crowded antioxidant category, this profile creates a
clear technical point of difference and supports premium positioning that’s grounded in science.
How TetraSOD® works
Most traditional antioxidants work by directly neutralising free radicals, donating electrons to them and
effectively acting as an off switch. But TetraSOD® works differently, acting instead as an indirect
antioxidant.
Rather than neutralising free radicals on behalf of the cell, it helps switch on the cell’s own defence
systems – supporting the body to produce and regulate its own protective enzymes. This allows the
body’s cells to respond to stress in a more natural and balanced way.
Research shows that TetraSOD® activates key regulatory pathways in human cells, including NRF2
and SIRT1. These are often described as the ‘master switches’ for antioxidant defence and healthy
ageing, but both naturally decline as we age. By helping activate these pathways, TetraSOD®
supports cellular balance, DNA integrity, healthy cellular signalling and long-term resilience to
environmental and metabolic stressors.
TetraSOD® has also been shown to help your cells make new mitochondria, clear out damaged ones,
and improve how efficiently they produce energy, supporting healthier, more resilient cells at a
fundamental level.
Why this matters
TetraSOD® is a foundational ingredient for next-generation formulations, particularly those operating
at the innovative and higher end of the market.
A technically differentiated ingredient with a clear mechanism of action and clinically supported
outcomes, it offers a far more compelling sales narrative than ‘high-strength antioxidant’.
Instead, it’s an ingredient that can be positioned as next-generation cellular support, allowing products
that contain it to be anchored in cellular resilience and longevity science.
A foundation for the longevity era
Longevity is shifting from trend to expectation. As consumers become more educated, there’s
naturally more interest in how ingredients work.
TetraSOD® is an ingredient that offers consumers more than a simple antioxidant. It supports the
body’s own protective systems and helps maintain cellular balance, offering a systems-based
approach to healthy ageing.
In future blogs, we’ll explore in greater detail what makes TetraSOD® different, how it fits within
longevity science, and the research that underpins its benefits.
