Sorry to rain on your parade but psyllium plants soak up lead, and ConsumerLabs tested different brands and they all had significant lead, and like half of them had more lead than California’s suggested maximum. No way to avoid it. I switched to Citrucel or something generic that doesn’t have that problem.
That’s a good point, but unfortunately I’ve never seen any evidence that your body does or does not absorb the lead from psyllium fiber, or if the fiber maybe even absorbs more lead from your body on the way through. All I know is that psyllium fiber has lead in it, and that there are other sources of fiber that don’t.
