What is Phytoplankton

Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.

Like land plants, phytoplankton have chlorophyll to capture sunlight, and they use photosynthesis to turn it into chemical energy. They consume carbon dioxide, and release oxygen. All phytoplankton photosynthesize, but some get additional energy by consuming other organisms.

Phytoplankton are the foundation of the aquatic food web, the primary producers, feeding everything from microscopic, animal-like zooplankton to multi-ton whales. Small fish and invertebrates also graze on the plant-like organisms, and then those smaller animals are eaten by bigger ones.

Phytoplankton are the primary producer of the oxygen we breathe, and the number one recycler of CO2.

Our Phytoplankton

Karen for Good Health's team of researchers came together to formulate and stabilized a variety of strains of phytoplankton into our all-natural active ingredients, Gaditae™ and TetraSOD® and the results speak for themselves

  • Gaditae™ is the master antioxidant of all the phytoplankton. It is a natural,
    vegan and non processed AI (ACTIVE INGREDIENT) that helps fighting oxidative stress, avoiding cell damage and multiple health challenges.

    Gaditae™ is granted with an NPN by Health Canada with a General Antioxidant claim: It is a source of zeaxanthin, an antioxidant for the maintenance of good health.

    Gaditae™ is a unique ingredient that has been actively researched due to its content in promising compounds such as Omega 3´s, Antioxidant pigments and functional proteins.

  • TetraSOD® is NOT AN EXTRACT. It is a patented ingredient based on the
    unicellular marine microalgae Tetraselmis chuii. Induces endogenous
    production of SOD, GPx and CAT in human cells, boosts antioxidant
    pathways and modulates the immune system via regulation of the
    NRF2/HMOX1 antioxidant/anti-inflammatory pathway.

    TetraSOD®™ is granted with a NPN number by Health Canada with many
    approved claims, such as antioxidant, protect from free radicals, Helps in
    wound healing. Helps in collagen formation to maintain healthy bones,
    cartilage, teeth and/or gums. Helps to maintain immune function… and
    many more.

    TetraSOD® is more than just an antioxidant. It is a proven and
    scientifically researched ingredient that prevents cell damage under
    many conditions.

Oxidative Stress

Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, leading to organ and tissue damage and the development of various diseases. Adopting a healthy lifestyle can help maintain this balance.

Free radicals are molecules with an uneven number of electrons, making them highly reactive and capable of initiating chain chemical reactions in the body known as oxidation. These reactions can have both beneficial and harmful effects.

Antioxidants, on the other hand, are molecules that can donate electrons to free radicals without becoming unstable themselves. This process stabilizes the free radicals, reducing their reactivity.

Scientific studies have linked oxidative stress to over 200 chronic diseases. Some health issues associated with oxidative stress include cardiovascular disease, infertility syndromes, hearing loss, chronic inflammatory diseases, cognitive impairment, joint diseases, and skin pathologies.

Researchers have discovered that genetic mutations and manipulations that increase resistance to oxidative stress also lead to extended lifespan. Therefore, interventions aimed at reducing free radicals are crucial for promoting a healthy ageing process.

The superoxide dismutase

The superoxide dismutase (SOD) enzyme acts as the primary defense against oxidative stress. It has been protecting living organisms from oxidation for billions of years. SOD plays a critical role in controlling the production of reactive oxygen species and preventing cell oxidation.

Our Phytoplankton strain TetraSOD® is a unique product that contains 30,000 IU/g of SOD activity, making it the most concentrated source of SOD currently discovered.

SOD acts as the first line of defense against oxidative stress. Phytoplankton has been scientifically proven to activate the antioxidant response pathway in human cells. In addition to SOD, TetraSOD® also contains other beneficial components such as GPx and CAT enzymes, essential fatty acids, antioxidants, vitamins, minerals, amino acids, and pigments. It is a well-rounded functional ingredient with a balanced nutritional composition.


We Cultivate, never collect from the ocean.

In Cadiz, Spain is Blugenics’ one-of-a-kind growing facility, where all Karen for Good Health products are grown. The facility safely isolates and cultivates phytoplankton at the highest safety standards and 100% sustainability.
