Finding Healthier. Feeding Solutions. Parapharma Tech started as a mission to provide a healthier alternative thickening option to cereals for infants with reflux. In 2010, we developed Gelmix thickener for breast milk and formula. In 2018, we expanded our line to include Purathick, for hot and cold beverages, for adults and children over 1. Ingredients matter, and our mission continues on as we strive to develop new healthful organic products and supplements for pediatrics and adults.
