BIOKELP® is a concentration of Eklonia maxima algae obtained through a natural process of room-temperature pressing, without the use of chemical solvents. This guarantees the acquisition of a product rich in phytohormones such as auxin and cytokinin; these are particularly active and do not undergo the negative impacts of an invasive production process. Zinc and manganese help the synthesis of enzymes which are fundamental for the most important metabolic processes of the plant.
