All Purella functional products are carefully tested and certified. Throughout the entire supply chain,  BIO / Organic standards are implemented to make sure that from the harvest itself, through production, to delivery to the final consumer, the appropriate quality requirements are met. BIO / Organic certification also ensures that only ecological methods are used during cultivation and production, and the soil on which the works are carried out is clean and does not contain heavy metals or other pollutants. Each of our products is NON-GMO certified, which means that none has been modified to accelerate growth.
