I have been using GI Fortify for years. It helps keep me regular while also healing and soothing my intestinal lining. I have found that it can really help balance out most digestive challenges that appear, whether it be the aftermath of food poisoning or the day after eating foods that I don't digest well. My recommendation it to put a scoop into a small glass jar, add water, close it up and shake shake shake before drinking.
Works great on the headaches Invisalign trays cause.
