TetraSOD® 250 mg
The Marine Antioxidant Enzyme Activator
A patented marine microalgae extract, clinically studied for promoting antioxidant defence systems, particularly superoxide dismutase (SOD), which is often referred to as the body’s ‘first line of defence’ against oxidative stress.

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 the body’s endogenous antioxidant enzymes (SOD, catalase, glutathione peroxidase), creating a self-sustaining antioxidant effect (by increasing gene expressions).
TetraSOD® supplementation may lead to:
- Improved male reproductive health by increasing sperm count
- Increased muscle mass and testosterone in males while decreasing fat mass
- Decrease in oxidative stress and inflammation through its antioxidant enzymes (as demonstrated in animal models)
- Enhanced exercise performance by increasing VO2 max (a measure of using oxygen during exercise)
- Promotion of beneficial microbes in the gut (e.g. species from Akkermansia, Butyricimonas genera)
What is Superoxide Dismutase (SOD)?
SOD is a critical antioxidant enzyme that neutralises superoxide radicals, the most damaging form of free radicals. Declining SOD activity is linked with excess ageing, inflammation, and metabolic syndrome risks.
TetraSOD® provides a natural source to boost SOD levels, turning on the body’s own antioxidant system rather than relying solely on external antioxidants.
What is the Recommended Daily Dose of TetraSOD®?
Human clinical studies support 250 mg per day of TetraSOD® for antioxidant defence, exercise performance, and anti-inflammatory benefits.
