At the moment, we do not offer the option of adding extra fiber to your Personalized Protein blend. However, we do offer a Fiber Performance Boost that you can add separately to your subscription. This can also be easily added directly to your protein shake if you'd like.
Additionally, to increase your fiber intake in your protein shake, you can try blending it with frozen fruits, vegetables, oats, peanut butter, etc. A protein-rich smoothie can be a delicious way to get extra fiber and nutrients from whole foods.
