Enterin, I actually The psyllium powder, where the husk/shell has been ground down to a very fine powder. There are great ways above on examples of use!
I have for most of 13 years am 95% loose stools. So my use is a measuring tsp In 8 oz of cold or cooler water (no warm tap as it thickens it quickly and can cause choking problems). I use 3 to 4 times a day. Definitely Before I drink my coffee, so it has something to bind to and before meals as others shared. 🤗
Now, I stopped taking it in pill because my stomach passed them too quickly and they tried to dissolve in my ilium and formed a blockage! Scary and painful was blessed hand massage, gently over 3 hours I got it to pass. I still have some strictures that can cause blockages, so I just always pay attention if there is any pain in gut. Good luck!
