As stress can negatively influence IBS symptoms, this product stands out due to Ashwagandha, a well-known adaptogen that may help to promote a sense of calmness.

If you choose to purchase Routine, right now one package containing 30 servings is priced at $39.95 (or $1.33 per serving). This product is also covered by a 30-day refund policy in case you do not find yourself completely satisfied with the results.

What is IBS and do I have it?
Irritable Bowel Syndrome (IBS) is a common chronic functional disorder that affects the gastrointestinal tract. Although the symptoms will vary from person to person, the most common are bloating, abdominal pain, diarrhea, or constipation.
However, if you have these or similar symptoms, it does not automatically mean you have IBS, as these symptoms could be caused by other factors such as overeating, low fiber intake, and several other conditions.
If you suspect you may have IBS, it is crucial to seek advice from your healthcare provider. A doctor will perform a thorough examination to confirm or rule out IBS or other potential underlying conditions.
There is no cure for IBS, but there is a wide range of management strategies people can employ to reduce IBS symptoms. Most people can control their symptoms by improving their diet and lifestyle. For instance, dietary modifications can include identifying and avoiding specific foods that trigger IBS symptoms. The management plan will be discussed with your doctor after getting the diagnosis.
IBS symptoms will vary from person to person. The most common include abdominal pain, bloating, gas, and changes in bowel habits. Moreover, there are 3 types of IBS that differ in symptoms.
- IBS with constipation (IBS-C). The most common concern for individuals with IBS-C is constipation.
- IBS with diarrhea (IBS-D). This type of IBS is defined by frequent episodes of diarrhea.
- Mixed IBS (IBS-M). If you have this type of IBS, you may experience both constipation and diarrhea.
Tips on how to choose the right IBS supplement
If you have decided to start taking supplements to manage your IBS symptoms, there are a few things that are important to keep in mind before you purchase any product.
- Identify your symptoms. Since supplements can not treat or cure IBS, only to help relieve certain symptoms, identify what issues or concerns you would like to address by taking OTC supplements for IBS. Ideally, you should discuss this with a registered dietitian or medical practitioner before you choose the supplement.
- Consider the ingredients. Certain active ingredients in supplements may be more beneficial for IBS than others. For instance, probiotics for IBS may help to relieve certain symptoms that are common complaints for people with IBS: bloating, flatulence, and diarrhea.
- Consult your physician. If you decide to incorporate IBS supplements into your routine, it is advisable to consult with a healthcare professional. They can help you choose the best supplements for IBS according to your diagnosis.
Are IBS supplements safe?
The safety of IBS supplements will depend on the active ingredients and the individual's health status.
For instance, probiotics are one of the most common ingredients of IBS supplements. Probiotics are generally considered to be safe. However, some individuals, including people with compromised immune systems, should avoid taking them
Furthermore, IBS supplements may cause side effects, but they are generally mild. The most common side effects include symptoms such as diarrhea, stomach pain, or nausea. These symptoms usually resolve after a couple of weeks of regular use.
Check the label of the supplement you are considering purchasing. Some IBS supplements may include essential minerals and vitamins that could be in levels that are too high and lead to adverse effects in your individual case. For this reason, it is important to discuss with a healthcare professional if you should incorporate supplements in your routine.
IBS supplements vs. dietary changes
Dietary changes are usually the first step in IBS management. The most commonly prescribed dietary strategy for IBS is a low-FODMAP diet. Moreover, lifestyle changes should be considered as well. Most people can cope with IBS by improving their diet, lifestyle, and reducing their stress levels.
If permitted by the supervising healthcare professional, IBS supplements may be also introduced. As there is no cure for IBS, people diagnosed with this syndrome focus on effectively managing their symptoms, and some of the supplements may offer that. For instance, probiotics may be helpful for some in reducing bloating, diarrhea, constipation, and flatulence.
People with IBS may also be at risk of certain vitamin and mineral deficiencies. For instance, some studies suggest that not only people with IBS are more likely to develop deficiencies in vitamin D, but supplementation of it may reduce the severity of some of the IBS symptoms. It is worth mentioning that some research studies on vitamin D and IBS showed mixed results suggesting that it may not have any effect on IBS patients. If you suspect you may have a deficiency in certain vitamins or minerals, consult your healthcare provider for further evaluation.
Maintaining gut health with supplements for IBS
Certain supplements for IBS may be beneficial for maintaining gut health.
For instance, probiotics are an important factor in keeping your gut healthy. These beneficial bacteria, naturally present in the human body, contribute to such functions as digestion. If you have a disbalance in your gut microbiota, you may have such symptoms as bloating, upset stomach, diarrhea, and constipation — resembling those observed in individuals with IBS.
Probiotic supplements may balance out your gut microbiota and thus reduce the mentioned symptoms. Keep in mind that you can also acquire probiotics through diet, as there is a myriad of food products that contain “good” bacteria, such as yogurt, kimchi, sauerkraut, other pickled vegetables, and kefir.
Another important factor to be considered is dietary fiber — carbohydrates that are not digestible by humans. Although their benefits are often overlooked, fiber is essential in our diets as it promotes regular bowel movements and prevents constipation. After discussing the best IBS management strategy with a registered dietitian, people with IBS could benefit from increasing their fiber intake if they do not meet the recommended 25 grams of fiber target per day. One review concluded that supplementation with fiber, particularly psyllium, may help to reduce IBS symptoms.
Supplements should not be used in place of a well-balanced diet, but they may help support one’s health when incorporated as part of a holistic approach.

Are IBS supplements safe for long-term use?
Some IBS supplements on the market have not been properly studied for their long-term effects, therefore, it is important to select products together with a healthcare provider. Moreover, ingredients in supplements are not thoroughly studied and usually do not undergo the same rigorous testing as medications.
Do IBS supplements interact with medications?
Some ingredients in IBS supplements may interact with medications. Inform your healthcare provider if you are considering to start taking supplements if you are prescribed medications.
How can I monitor the effectiveness of my IBS supplements?
To monitor the effectiveness of your IBS supplements, you may keep a journal of your symptoms. The journal could include other factors that may influence IBS symptoms such as diet choices and stress levels. Moreover, it may be worth considering contacting your doctor to help you track your progress.
