A smooth muscle relaxant that targets bloating and cramping — the GI discomfort layer that ginger alone doesn't address.
Peppermint leaf (Mentha × piperita) contains menthol and menthone as its primary active compounds. In the GI context, menthol is the key actor: it functions as a calcium channel antagonist in smooth muscle, reducing the muscle contractions that cause cramping, spasm, and the trapped-gas sensation of bloating.
This mechanism is distinct from peppermint oil (often used in enteric-coated capsules for IBS) — peppermint leaf in powder form delivers a consistent, well-tolerated dose without the heartburn risk associated with oil formulations.
GLP-1 therapy slows gastric emptying, which means food and gas sit in the digestive tract longer than usual. The result for many people is bloating, cramping, and a persistent sense of fullness that becomes uncomfortable rather than convenient. Ginger addresses nausea at the receptor level; peppermint addresses the smooth muscle tension that causes the bloating and cramping from the same delayed motility.
The two mechanisms work in parallel. Clinical research on IBS — which shares the smooth muscle dysfunction and motility disruption patterns common in GLP-1 side effects — consistently shows peppermint to be one of the most effective plant-based interventions for bloating and cramping at doses between 180–250mg.
200mg sits within the clinical range associated with reduced bloating and cramping in IBS and functional GI disorder trials. It's also a dose that's easy to tolerate without the GI irritation that higher oil-based doses can cause. As a leaf extract rather than an oil, it works well in a stick-pack format without compatibility issues.
Peppermint Leaf is one of three ingredients in GI Relief. It works alongside Ginger Root Extract (nausea/motility) and Soluble Fiber (gastric regulation and satiety) to cover the full GI side-effect profile of peptide therapy.
Three complementary mechanisms. One formula for staying comfortable on your protocol.
