Symbio liquid seaweed is a super concentrated extract of Ascophyllum nodosum with approx. 50% active matter harvested from the Atlantic Ocean from renewable resources. It contains a natural balance of macronutrients and chelated micronutrients (>60 elements), carbohydrates, amino acids, antioxidants and other beneficial organic compounds.

Symbio 50% Seaweed is a 50% w/v growth stimulant manufactured from Ascophyllum nodosum (L.) sustainably harvested from renewable resources in the Atlantic Ocean. It contains a natural balance of macronutrients and chelated micronutrients, carbohydrates, amino acids, antioxidants, natural growth stimulants and other beneficial organic compounds. The unique feature is the high concentration of active material in the extract. This concentration is achieved through the extraction process. The product is extracted using alkaline hydrolysis at high pressure and temperature. The high pH and high temperature allow for the concentration of bioactive molecules, which are not available in the same amount with a cold pressed extract. This extraction process produces complex polysaccharides which serve as excellent food sources for soil microorganisms. Two of these polysaccharides, laminaran and fucoidan have also been shown to exhibit a wide range of biological activities within plants such as improved tolerance to environmental stress and induction of natural plant defence against pathogens. The extraction technique used in Symbio 50% seaweed results in higher concentrations of these bioactive compounds.
