NutriStack
Psyllium Husk and Zinc, timing-sensitive.
Psyllium gel can bind zinc in the intestinal lumen, reducing the fraction of zinc absorbed when the two are taken at the same time.
One pair, every claim cited. The two substances, the type, the mechanism, the recommendation, and the primary literature.
Same shape as the other 1,729 pairs in the public database.

Timing Sensitive
What is happening. Psyllium gel can bind zinc in the intestinal lumen, reducing the fraction of zinc absorbed when the two are taken at the same time.
Mechanism. The viscous soluble fiber matrix traps divalent zinc cations and limits mucosal contact while speeding transit, decreasing intestinal zinc uptake.
Recommendation. Separate zinc and psyllium by at least 2 hours. Take zinc with a light meal away from your fiber dose.
Minimum separation. 2 hours
