NAN 3 (12+ months): A growing-up milk that supports energy needs and development alongside a regular diet.

All types are fortified with OPTIPRO® and probiotics to promote healthy digestion and strengthen the immune system.

Difference Between NAN 1, NAN 2, and NAN 3

NAN 1: Suitable from birth to 6 months; used as an alternative when breastfeeding is not available.
NAN 2: Suitable from 6 months to 1 year; complements breastfeeding and helps babies adapt to solid foods.
