Ingredient
TetraSOD®
The Marine Antioxidant Enzyme Activator
A patented marine microalgae extract (Tetraselmis chuii) — the most concentrated natural source of Superoxide Dismutase (SOD) — that stimulates the body's own antioxidant enzyme systems.
What is TetraSOD® Good For?
TetraSOD® is the most concentrated SOD source found in nature, enriched with essential marine nutrients. Unlike direct antioxidant supplementation, it stimulates endogenous antioxidant enzymes (SOD, catalase, glutathione peroxidase), creating self-sustaining antioxidant effects through gene expression increases.
Potential benefits of supplementation
- Improved male reproductive health via increased sperm count
- Increased muscle mass and testosterone in males; decreased fat mass
- Reduced oxidative stress and inflammation through antioxidant enzymes (animal models)
- Enhanced exercise performance by increasing VO2 max
- Promotion of beneficial gut microbes (Akkermansia, Butyricimonas genera)
What is TetraSOD® 250 mg?
SOD functions as a critical antioxidant enzyme neutralizing superoxide radicals—the most damaging form of free radicals. Declining SOD activity correlates with accelerated aging, inflammation, and metabolic syndrome risks.
TetraSOD® provides natural SOD elevation, activating the body's own antioxidant system rather than relying solely on external antioxidants.
Recommended Daily Dose
250 mg
250 mg per day, supported by human clinical studies for antioxidant defence, exercise performance, and anti-inflammatory benefits.

Your Questions About TetraSOD®
What is TetraSOD®?
A patented marine microalgae extract, the most concentrated natural source of SOD, designed to promote the body's antioxidant defence system.
What are the benefits of TetraSOD®?
Boosts cellular antioxidant enzymes, supports physical exercise, improves gut microbiome, and protects against oxidative damage.
How is TetraSOD® different from regular antioxidants?
Unlike vitamins C or E, which work directly, TetraSOD® stimulates the body's own antioxidant enzymes, creating a more sustainable and long-lasting defence.
Are there any side effects?
TetraSOD® is safe and well tolerated at the recommended dose.
Can TetraSOD® be combined with other antioxidants?
Yes, it complements direct antioxidants like glutathione, CoQ10, and alpha lipoic acid, enhancing overall redox balance.
