At the moment, we do not offer the option of adding extra vitamins and minerals to your blend. The nutritional profile of your personalized protein powder blend comes 100% naturally from the foods they are derived from (i.e. milk, peas, rice).
However, certain types of protein such as pea protein naturally have higher iron content than other sources. If you're interested in exploring the differences in iron content between different proteins, shoot us a message to firstname.lastname@example.org and we'll see if there's another protein source closer suited to your needs.
