Can anyone give me a good recommendation for a fiber supplement that meets this requirement:
"The natural balance of 75% insoluble to 25% soluble fiber is by taking a flax-based fiber. Flax provides roughly the same natural balance (approximately 65-75% insoluble to 25-35% soluble fiber). Most fiber supplements use psyllium fiber. Psyllium provides the opposite of the natural balance, approximately 20% insoluble fiber and 80% soluble fiber (thatâ€™s why it swells and gels so significantly).
