Zinc may mitigate granisetron constipation
Carbon monoxide contributes to the constipating effects of granisetron in rat colon.
Specific interaction with granisetron
We investigated how zinc might play a role in alleviating the constipation effects caused by granisetron, a medication often used to prevent nausea. In the studies, male rats were treated with varying doses of granisetron, alongside zinc protoporphyrin IX (ZnPPIX), to see how these compounds interacted.
Interestingly, while granisetron was found to increase the time to first defecation in the rats, ZnPPIX alone did not have a notable effect on constipation. However, when combined with granisetron, ZnPPIX successfully reversed the constipation induced by this medication. This suggests that zinc, acting through the heme oxygenase/carbon monoxide (HO/CO) pathway, could potentially mitigate constipation.
Nonetheless, it’s crucial to note that ZnPPIX’s effectiveness was only observed when paired with granisetron; its standalone administration didn’t significantly alter gastrointestinal motility. This highlights a specific interaction rather than a general benefit of zinc in treating constipation.

No constipation reported
This quality zinc in zinc bisglycinate chelate form is gentle on my stomach, doesn't cause constipation and is well absorbed. Zinc supports immunity, hormone and protein production, and reproductive health. It is essential for the proper function of many organs. I’ve read that calcium can reduce zinc absorption; hence, these should not be taken simultaneously.
