I prefer NOW brand or Konsyl, no additives at all just pure psyllium husk powder. Konsyl is pretty pricey unless you find it in bulk lots on eBay, NOW is super cheap. I put it in a glass of diet cranberry-raspberry juice (or diet cran-mango) so I don't want flavors. Most of all I don't want or need dextrose or any other sugars/sweeteners. I'm passionate about the stuff though. I was having passing thoughts of de-pouching when I took someone's suggestion to try it instead of the Benefiber I had been taking for 12 years. It changed my life, now my pouch is tamed (◠‿◕)
