Everything that interacts with l-glutamine.
Every supplement and medication in the NutriStack database with a documented interaction with this substance, highest-severity first. Open any pair for the mechanism and sources.
| Substance | Interaction | What happens |
|---|---|---|
| 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... |
| Colostrum | Synergy | Colostrum and L-glutamine are frequently combined for gut barrier support, as both contribute to intestinal mucosal repair and integrity. |
| L-Glutathione | Synergy | Glutamine is a substrate for glutathione synthesis (via glutamate). Combined use supports antioxidant capacity in critical illness and gut health. |
| Probiotics | Synergy | L-glutamine fuels intestinal cells and supports the gut barrier, complementing the way probiotics strengthen the mucosal lining. |
| Saccharomyces Boulardii | Synergy | L-glutamine and the probiotic yeast Saccharomyces boulardii are often combined for gut barrier and digestive support, acting through complementary... |
| Zinc Carnosine | Synergy | L-glutamine and zinc carnosine are a complementary gut-repair pairing, both promoting integrity and healing of the intestinal and gastric mucosa. |

Quick answers drawn from the table above.
What interacts with L-Glutamine?
In the NutriStack database, L-Glutamine has 6 documented interactions with other supplements and medications. The most notable include Psyllium Husk, Colostrum, L-Glutathione, Probiotics, and Saccharomyces Boulardii.
What works well with L-Glutamine?
L-Glutamine pairs synergistically with Colostrum, L-Glutathione, Probiotics, Saccharomyces Boulardii, and Zinc Carnosine in the NutriStack database. Synergy still depends on dose and timing; open any pair for the detail.
Can you take L-Glutamine with Psyllium Husk?
NutriStack classifies the L-Glutamine and Psyllium Husk pairing as 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... Separate L-glutamine and psyllium by at least 2 hours. Take L-glutamine on its own with water, away from your fiber dose.
