The origin of marine phytoplankton (microalgae) dates back to 2.5 billion years. These organisms were responsible for the production of oxygen that turned the atmosphere of our planet into a "breathable" environment that allowed the development of other life forms.
We cultivate the phytoplankton for TetraSOD®, we do not collect from the oceans.
With an area of 11,300 hectares and in the heart of the Doñana Nature Reserve, Veta La Palma estate constitutes an authentic natural paradise and a perfect example of biodiversity. Over 250 different species of birds and fishes feed in its abundant waters. But below its waters, it hides a true environmental treasure: marine phytoplankton.
After an intensively work for 15 years in the searching of active marine ingredients, our scientific and R&D team has discovered an exclusive strain with the highest antioxidant bioactivity directed to maintain a healthy ageing, boosting the natural processes of detoxification.
SOD activity comparison: TetraSOD® and other available products
TetraSOD® is a unique marine ingredient (marine microalgae Tetraselmis chuii) that is grown under patent-protected technology that accumulates 30-fold more SOD activity than any other marine phytoplankton strain on the market today (30,000 IU/g SOD activity).
SOD (Superoxide dismutase) is the first essential enzyme in the antioxidant pathway, which makes it the first shield against oxidative stress
TetraSOD® is the most concentrated SOD source in the market, with science backed demonstrated efficiency on activating the antioxidant response pathway on human cells.
TetraSOD® is not only a SOD product, but also a healthy functional ingredient with the most balanced nutritional composition: it contains the three antioxidative enzymes (SOD, glutathione peroxidase and catalase), essential fatty acids, antioxidants, vitamins, minerals, amino acids and pigments.
Per 1 g
Superoxide Dismutase Activity
CAA (Cellular Activity Assay)
38.94 µmole QE
ORAC (Oxygen Radical Absorption Capacity)
34.300 µmole TE/100 g
To assure the antioxidant capacity, two tests are combined: ORAC 5.0 (total antioxidant power against the five reactive species in vitro) and CAA (antioxidant capacity in living cells).
TetraSOD® is the most complete and comprehensive ingredient for the Healthy Ageing nutraceutical category but also offers athletes and individuals with active lifestyles an increased physiological response against oxidative stress to aid performance and recovery.
A fundamental advantage of TetraSOD® is the very small daily dosage needed for the different possible applications, ranging from 4,67 mg which would be a basic antioxidant product to 25 mg for a full spectrum of health benefits from TetraSOD® supplementation.
Ultimately, TetraSOD® is much more than just SOD.
Superoxide dismutases (SOD) are considered key factors in cellular protection against superoxide, representing the first line of defense to prevent oxidative damage, being the most powerful antioxidant in the cell. SOD catalyzes the dismutation of superoxide anion to hydrogen peroxide (H2O2), which is further transformed to water (H2O) and molecular oxygen (O2) by the accessory enzymes glutathione peroxidase (GPx) and catalase (CAT).
Given the critical function of SOD, these enzymes can be found in all taxonomic groups of living organisms, from prokaryotes (archaea and bacteria) to lower and higher eukaryotes, differing in the number of different enzymes they possess. All known SOD are metalloenzymes, that is, they require a metal cofactor for the activity, with iron (Fe), zinc (Zn), nickel (Ni), copper (Cu) and manganese (Mn) being those normally bound to SOD.
TetraSOD® exhibits the highest SOD activity found currently in nature. Under the production technology developed by Fitoplancton Marino, figures higher than 30,000 IU/g of biomass can be measured. A detailed bioinformatic analysis of the available genetic information for the microalgae T. chuii has allowed the identification of three genes encoding for SOD, each one potentially corresponding to either Mn, Cu-Zn, or Ni isoforms. The combined action of these three enzymes contributes to the extremely high global SOD activity displayed by TetraSOD®.
We cultivate (never collect) a unique marine phytoplankton that is grown under patent-protected technology to create TetraSOD®, the most powerful ingredient against oxidative stress.
TetraSOD® is produced to a green and sustainable patented process that assures the highest quality and without any physical or chemical following reaction
