While 98% of Nestlé's products sold in Chinese mainland are made locally, its premature infant milk powder is produced at its Biessenhofen plant in Munich, Germany. Biessenhofen is one of Nestlé's largest infant formula production sites, with more than 100 years of experience in the production and management of high-end infant nutrition products, and strict quality control. The high energy density of Nex provides energy requirements for rapid growth in preterm and low birth weight infants, and sufficient calcium and phosphorus as well as an ideal Ca/P ratio contribute to bone mineralization in preterm infants without increasing the additional burden on the kidneys and immature organ systems. Nestlé's premature infant milk powder is affordable.
