Enteric coated peppermint oil capsules, as part of the diet, have been clinically proven to help prevent IBS symptoms, even in children.
A Phytomedicine survey of 16 clinical trials declared peppermint capsules the approach "of first choice" for IBS patients.
Peppermint oil is exceptionally beneficial for IBS abdominal pain and spasms, diarrhea, and urgency.
By relaxing the gut, it can also benefit constipation.
Menthol and methyl salicylate, the main active ingredients of pure mentha piperita peppermint oil, have calming effects on the stomach and intestinal tract.
Peppermint is such a powerful smooth muscle relaxant that it can trigger heartburn in people who are susceptible.
But Heather's Tummy Tamers Peppermint Oil Caps use a very special inherently enteric gelatin shell so they do not dissolve in the stomach.
Instead, they pass through the digestive tract intact until they reach the intestines.
For this reason, Heather's Tummy Tamers Peppermint Oil Caps are often very helpful for people with both reflux and IBS who cannot tolerate peppermint in other forms (such as teas or foods).
Fennel is a carminative.
It helps relax the gut, regulates contractions of the small intestine, and aids bloating and gas.
Fennel also relaxes the gut, which can relieve spasms of the GI tract.
Ginger contains powerful digestive enzymes and is helpful for a wide variety of gastrointestinal ailments, particularly nausea.
Heather's Tummy Tamers Peppermint Oil Capsules are a medical food for IBS.
They are specially formulated to address global IBS symptoms through the synergistic effects of peppermint, fennel, and ginger oils.
A 2018 survey of clinical trials declared peppermint oil capsules the approach "of first choice" for IBS patients with constipation or diarrhea, to alleviate general symptoms and to improve quality of life.
A 2005 study in Phytomedicine reviewed 16 clinical trials investigating enteric-coated peppermint oil capsules in IBS.
The review concluded that peppermint oil capsules may be the approach of first choice in IBS patients with non-serious constipation or diarrhea to alleviate general symptoms and improve quality of life.
While there are several different brands of peppermint oil capsules on the market, Tummy Tamers are the only ones formulated specifically for the special needs of people with IBS.
How do we do this?
Our first concern is that people with IBS are statistically more prone to heartburn, and peppermint is contraindicated for people with heartburn, GERD, and reflux.
We have tried very hard to work around this problem, however.
The Tummy Tamers capsules use a special patented enteric gelatin shell.
This allows them to pass through the stomach without dissolving until they reach the small intestines.This enteric gelatin is resistant to stomach acid.
In fact, we are the only peppermint oil capsule manufacturer that uses enteric gelatin, so that as many people as possible are able to use them for IBS without aggravating any upper GI issues.
Second, we formulated Tummy Tamers to contain not just peppermint oil but fennel and ginger oils as well.
Clinical studies have shown that peppermint oil is exceptionally beneficial for IBS abdominal pain and spasms, diarrhea, and urgency (and it will NOT worsen constipation).
Fennel is a powerful carminative.
It helps relax the gut, regulates contractions of the small intestine, and aids bloating and gas. Plus, it's known to have a calming effect on the bowel.
Ginger contains powerful digestive enzymes and has historically been used as a digestive aid for stomach issues, gas, and nausea.
In addition, both fennel and ginger are traditional remedies for heartburn.
Together with the peppermint oil in the Tummy Tamers, they have a synergistic effect on global IBS symptoms without the heartburn risk of peppermint alone.

My digestion is better, my flare-ups are less frequent and less intense when I have them (cheated on the food I can tolerate). My life has improved so much since I have started using them. I have also ordered them for friends who suffer from IBS and it has changed their life too. Thank you again for having shone and continuing to shine a light and educate IBS sufferers on what they can do to lessen their pain, discomfort and ease their mind. | |
