My cholesterol is a little high and I was sometimes getting diarrhea after lunch if I ate a piece of fudge for dessert so I decided to start taking Top Care Sugar Free Fiber Powder. Three days in taking 1 tsp twice daily, my bowel movements started growing and the third day I had a large one twice. That afternoon, I felt tingles in my hands and calves and realized I was totally dehydrated. By that evening, my blood pressure was high in addition. Was it the psylium and how it works, the Phentlalanine or the Maltodextrin that would elicit this reaction of dehydration and high bp? Thank you very much for the help. I started drinking Propel to try to get my hydration back. It's a slow process. Have not taken this product since this.
