NutriStack
L-Glutamine and Psyllium Husk, timing-sensitive.
Psyllium forms a viscous gel that slows gastric emptying and small-bowel transit, which may trap free amino acids and theoretically reduce absorption of L-glutamine when the two are taken together.
One pair, every claim cited. The two substances, the type, the mechanism, the recommendation, and the primary literature.

Timing Sensitive
What is happening. Psyllium forms a viscous gel that slows gastric emptying and small-bowel transit, which may trap free amino acids and theoretically reduce absorption of L-glutamine when the two are taken together.
Mechanism. The soluble fiber gel increases lumen viscosity and slows mixing and diffusion, which can limit mucosal contact and uptake of small molecules, including free amino acids, taken concurrently.
Recommendation. Separate L-glutamine and psyllium by at least 2 hours. Take L-glutamine on its own with water, away from your fiber dose.
Minimum separation. 2 hours
