Evivo does contain lactose, which is the only simple carbohydrate found in breast milk and, as such, contains dairy. Evivo is manufactured using soy as a process ingredient. As long as your baby is not allergic to your own breastmilk, then Evivo will be perfectly fine to feed your baby. Unlike proteins and fats, all lactose is the same (i.e., lactose from bovine is structurally identical to lactose from human).
The final dried fermentation product is standardized with lactose. We do not expect any intact dairy or soy protein in the product and only trace amounts of peptides in the final product but cannot guarantee it. Evivo may contain trace amounts of milk and/or soy protein. We recommend you take this information to your pediatrician, to determine if this probiotic is suitable for your baby.
