So are you doing the cleanse right now or are you not? There’s no reason to take the psyllium, chia, or any fiber unless you are cleansing, so its not meant to be taken long term.
What results are you talking about? For most people, the psyllium causes chronic constipation that lasts for days. For many its negative results.
Theres many fiber products out there, but the one I use (during stage 1 and 2 of forum diet) is called miracle fiber which contains inulin which is a prebiotic that heals leaky gut. In other words, it feeds beneficial bacteria only. It also promotes good digestion and many other benefits. There are a few other inulin products out there; standard process makes a high quality one as well. This product is meant to not be taken during the cleanse.
