To safely use psyllium husk (the generic active ingredient), please consult your doctor first. For someone managing diabetes on insulin, it is crucial to purchase sugar-free, unflavored formulations, as some options contain added sugars that can spike blood glucose. Additionally, soluble fiber can slow digestion, which may alter your insulin absorption and requirements, so monitor your blood sugar closely when starting. Drink plenty of water with each dose to avoid any digestive blockages, which is especially important given your pancreatic history. Always buy your supplements from a licensed pharmacy to guarantee quality and safety.
