Isabgol
Psyllium husk or isabgol is primarily soluble, gel-forming fiber. Most sources, including NIH, report psyllium as being rich in soluble fiber with strong water-binding and gel-forming capacity. That gel slows gastric emptying and traps bile acids and some dietary fat and sugars. This effect produces measurable effects on cholesterol and blood glucose.
Chia seeds
Chia seeds contain about 30 to 40 g of fiber per 100 g, but 85–93% of that is insoluble fiber, with only a small soluble fraction, as per NIH. Insoluble fibers mainly increase stool bulk and speed transit
