NANKID® OPTIPRO® Four is the perfect milk for kids over three years old. It's packed with essential vitamins, minerals, and nutrients that are proven by over 20 clinical trials to support age-appropriate growth and proper nutrition. It has DHA and ARA, two building blocks for brain and eye development—and it comes with added sucrose (or table sugar) to help your children get all of the calories they need. It's also got a probiotic called B. Lactis that helps increase antibody response—so you can rest easy knowing your children are getting the support they need to keep them healthy while they're growing up. Plus, this milk is designed to be served immediately after mixing with water! If you don't have time to prepare food or drink now but still want something nutritious for your kids' lunches tomorrow—this is the perfect solution. NANKID® OPTIPRO® Four is not a breastmilk substitute; it is specifically designed for growing children between ages 3 and 10 years old. It does not expire until at least three weeks after opening and should be stored in a cool dry place after each use.
