Yes, you may mix Evivo with breastmilk, formula or water to feed to your baby. Our clinical studies show that breastmilk contains HMOs, the food that B. infantis needs to grow and thrive in the infant gut. Therefore, babies who are consuming a combination of formula and breastmilk (mixed feeders) are still receiving HMOs needed to feed B. infantis. However, babies that are exclusively formula fed are most likely not receiving HMOs in their diet, and therefore may not experience the full benefits of Evivo shown in our clinical trials.
