I don't think I would soak the psyllium. I'm assuming you are suggesting that this would increase their tolerability, similar to how lectin-concentrated foods like nuts or legumes are prepared.
No, b/c it is not possible to discard the water it is soaked in. I had been taking 1/2 teaspoon in one glass of water/juice with breakfast and dinner for a few days, apparently with no problems. But I was concerned with it binding nutrients.
In the meanwhile I started taking silymarin which fixed my temperature swings but caused detox reactions, and I took 1/2 teaspoon of psyllium husks in one glass of water about 45 min after the silymarin to bind toxins. But I didn't wait the usual 15 soaking minutes, it was still a little dry and I had a blockage for 3 days, until I precipitated things by taking lots of magnesium.
My problems really begun when I started taking my new psyllium husks delivered by iHerb, which seemed to be goitrogen, blocking the use of iodine to convert T4 into T3 - confirmed by a blood test that showed low T3. For now I have been avoiding iodine sources due to autoimmune thyroiditis. I hope to get antibodies down with hormone replacement and possibly by starting LDN as well. When antibodies are low enough it is my intention to go on an iodine protocol.
With this in mind I tried taking it before bed to avoid hypothyroid symptoms during the day. I have had bad nights before, but that one was really awful, I felt a weight pressure on my head and my chest against the bed, general autoimmune pain like I get from warfarin, gluten, potato starch, flaxseeds, etc., heart arritmia, increased urination. At least in the following morning I had a rare good bowel movement.
Now I backed off and am taking just a pinch in a glass of liquid and will try to build it up to 1/2 teaspoon daily slowly. Unfortunately this technique didn't work with potato starch (autoimmune pains), but then it wasn't worth it since it did close to nothing to my bowel movements.
@Vegas thank you so much for the information you posted on the subject, it will take me a while to process it all!
