Similac® offers a family of products to help meet the unique needs of your baby. Similac Pro-Advance® is our closest formula to breast milk and is the first and only formula in Canada with 2'-FL.† 2’-FL in breast milk helps build baby’s immune system. Our most advanced formula, Similac Pro-Advance® contains 2’-FL.† 2'-FL is backed by 20 years of research, and parents reported 3 times fewer respiratory infections in babies fed Similac® with 2’-FL.†‡ It also contains our exclusive blend of DHA, lutein, and natural vitamin E§. DHA, an Omega-3 fat, supports the normal physical development of the baby’s brain and eyes. Antioxidants, such as lutein and vitamin E help protect fats in body tissues, like DHA, from oxidation. Similac Pro-Advance® Step 2 is calcium-enriched and recommended for babies 6+ months. This formula is non-GMO*, easy to digest¶, and is made with milk from cows not treated with artificial growth hormones. Similac Pro-Advance® is available in these convenient ready-to-use bottles and easy-to-scoop powder format. † Not derived from human milk; identical structure to 2'-FL found in breast milk. ‡ Compared to babies fed a formula without 2’-FL. Post-hoc analysis. Doctor-assessed adverse events. § RRR-α-tocopherol, the most bioactive form of vitamin E. * Ingredients not genetically engineered. ¶ Similar to other infant formulas.
