Psyllium is a soluble, viscous fiber that forms a gel in the digestive tract. This action slows gastric emptying, which helps blunt post-meal glucose and insulin spikes, and binds to bile acids, which lowers LDL cholesterol. It also acts as a prebiotic, feeding beneficial gut bacteria that produce health-promoting short-chain fatty acids (SCFAs) like butyrate.
Verdict
A safe, cheap, and effective fiber for foundational metabolic health.
