Zinc may mitigate granisetron constipation
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
In my view, this chelated zinc from an excellent manufacturer is remarkable. Zinc glycinate chelate gently influences the gastrointestinal tract, does not induce constipation, and is well absorbed. Zinc is an essential mineral crucial for the proper functioning of internal organs and various body systems, including skeletal, immune, neurological, and endocrine systems. It serves as a cofactor in numerous enzymes within the body. Furthermore, zinc plays a role in cell growth, development, and DNA formation, bolstering immunity, stimulating hormone and protein production, promoting reproductive health, and assisting in normalising blood sugar levels. I highly recommend this supplement.
