Protein powder can be a great addition to your diet while nursing! Protein and calorie needs are increased during this time, so protein supplements are quite common among new mothers.
Assuming you and your baby are not allergic to any of the ingredients in your protein blend, you shouldn't experience any issues with your protein powder. You can view your full ingredients list and nutrition facts by logging into Gainful.com
