Probiotics are often praised for their potential benefits to digestive health, as they introduce good bacteria into your gut. Many people take probiotics to combat gastrointestinal issues, including gas and bloating. But can probiotics sometimes make gas worse instead of alleviating the issue?

When you first start taking probiotics, it’s common for your body to undergo an adjustment period. During this time, mild gas may occur as your body gets accustomed to the new balance of bacteria in your system. However, this initial increase in gas should not be severe or long-lasting. If you continue to experience worsening or persistent gas symptoms, it’s worth considering the specific probiotic strains you are consuming and their suitability for your gut health needs.

To find the most suitable probiotic for your individual circumstances, it is essential to experiment with different strains and dosages until you find the right balance. Keep in mind that not all probiotics are created equal, and the best choice for you may differ from what works for others.

Probiotics and Gas

How Probiotics Work

Probiotics are beneficial live bacteria and yeasts that, when consumed, can improve your gut health. They can be found in specific foods like yogurt or in supplements. The most common types of probiotics are Lactobacillus and Bifidobacterium. These microorganisms help maintain the balance of good and bad bacteria in your gut, ultimately supporting your digestion and gastrointestinal health.

Gas as a Side Effect

When you first start taking probiotics, your body may experience mild gas as it adjusts to the new bacterial balance in your gut. This is due to the increased activity of the newly introduced beneficial bacteria, which may produce gas as they break down food. However, this side effect is generally temporary and should subside as your body becomes accustomed to the probiotics. In some cases, people report that their gas smells worse than before taking probiotics, but this usually resolves within a few days to a week.

Relation with Bloating

Gas and bloating are closely related, as excessive gas production can lead to the feeling of fullness and discomfort associated with bloating. Probiotics may initially contribute to gas and bloating, but they can actually help alleviate these symptoms in the long run. According to research, Lactobacillus-containing probiotics have been shown to improve symptoms of gas production in patients with lactose intolerance and lactose maldigestion.

By supporting a balanced gut microbiome, probiotics play a vital role in reducing gas and bloating. This is because they help break down food more efficiently, reducing the fermentation and gas production that occurs when undigested food particles accumulate in your intestines. As your body adjusts to the probiotics, you may find that your gas and bloating symptoms improve, leading to better overall digestive health.

Factors Contributing to Gas with Probiotics

Digestion and Probiotics

Probiotics, which are live bacteria and yeasts, can be beneficial for your gut health when included in your diet. However, they may also cause gas in some individuals, primarily due to their impact on digestion. When you take a probiotic supplement or consume foods rich in probiotics, the friendly bacteria may help break down certain substances in your digestive tract, such as lactose, fiber, and sugars. This process may result in producing gas as a byproduct, which can lead to discomfort, bloating, or flatulence.

Strains and Individual Factors

The type of probiotic strain you consume can also contribute to gas production. Some strains, such as Lactobacillus and Bifidobacterium, might produce more gas in your system than others. It’s important to note that each individual’s gut microbiota is unique, and the strains that agree with one person might not necessarily suit another. When choosing a probiotic supplement or food source, you might need to experiment with different strains to find the most suitable one for your body.

Diet and Lifestyle Factors

Apart from the probiotics themselves, various diet and lifestyle factors can influence how your body reacts to these helpful bacteria and affect gas production.

  • Lactose: If you’re lactose intolerant, consuming lactose-containing foods like certain dairy products alongside probiotics might worsen gas and bloating.
  • Fiber: A high-fiber diet can cause increased gas production when combined with probiotics, as the bacteria break down the fibers, producing gas as a byproduct.
  • Sugar: Consuming probiotics with high-sugar foods can also contribute to gas, as the bacteria ferment the sugar, causing gas production.
  • Alcohol: Excessive alcohol consumption may hinder the positive effects of probiotics and exacerbate gas-related symptoms.
  • Exercise: Physical activity can help promote healthy digestion and may potentially reduce gas when incorporating probiotics into your routine.
  • Food sensitivities: If you’re sensitive to certain foods, consuming them alongside probiotics could worsen gas symptoms.

By paying attention to these factors, you can better understand your body’s reactions to probiotics and make necessary adjustments to your diet and lifestyle to minimize gas and maximize the benefits of probiotics for your gut health.

Reducing Gas and Bloating

Choosing the Right Strains

When it comes to using probiotics for reducing gas and bloating, it’s essential to choose the right strains. Some specific strains have been shown to be more effective against gas and bloating. For example, Lactobacillus and Bifidobacterium strains are known to help reduce intestinal fermentation and gas production. Make sure to read product labels carefully and choose supplements containing these strains to minimize any negative effects on your gut.

Adjusting Probiotic Dosage

The dosage of your probiotic supplement can also have an impact on gas and bloating. If you’re experiencing discomfort, it might be worth adjusting your probiotic dosage. Start with a low dose and gradually increase it as your body gets used to the supplement. Keep in mind that it’s normal for some mild stomach upset, gas, or bloating to occur for the first few days after starting a probiotic, as mentioned by the Cleveland Clinic. This should subside as your body adjusts to the new bacteria being introduced.

Dietary Modifications

In addition to selecting the right probiotic strains and adjusting your dosage, consider making some dietary modifications to help reduce gas and bloating. Here are some suggestions:

  • Incorporate prebiotics: Prebiotics are non-digestible fibers that serve as a food source for the good bacteria in your gut. Including more prebiotic-rich foods in your diet, such as bananas, garlic, and onions, can help support your gut’s bacterial balance and reduce gas production.
  • Increase fiber intake gradually: High-fiber diets are beneficial for overall gut health, but increasing your fiber intake too quickly can lead to gas and bloating. Gradually introduce fiber-rich foods, like whole grains, fruits, and vegetables, to minimize any discomfort.
  • Avoid gas-producing foods: Some foods are notorious for causing gas and bloating, such as beans, cruciferous vegetables (e.g., broccoli, cabbage), and carbonated beverages. If you’re particularly sensitive, try limiting or eliminating these foods from your diet, and see if your symptoms improve.

Remember, a combination of the right strains, appropriate dosage adjustments, and dietary modifications can help reduce gas and bloating while taking probiotics.

Probiotics and Digestive Issues

Irritable Bowel Syndrome

Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder that affects your digestive system, causing symptoms such as bloating, abdominal pain, and inconsistent bowel movements. Some evidence suggests that probiotics may help alleviate these symptoms by modifying the gut microbiota. However, it’s important to note that the effects of probiotics on gas production and IBS symptoms may vary depending on the specific probiotic strains and individual factors.

Digestive System and Microbiome

Your digestive system is home to a complex community of bacteria known as the gut microbiome, which plays a significant role in digestive health. Probiotics are beneficial bacteria that can help balance the gut microbiota and support the digestive system.

While probiotics have shown promise in alleviating various gastrointestinal symptoms, some individuals have reported an increase in gas production and worse-smelling gas when taking probiotics. It’s vital to understand that these effects may stem from differences in the gut microbiome and individual responses to specific probiotic strains.

Precautions and Other Considerations

When considering taking probiotics for gas or other digestive issues, it’s essential to keep some precautions in mind. Firstly, consult with your healthcare provider, especially if you have any pre-existing medical conditions or are taking medications. Secondly, select a probiotic product that has been well-researched, with clinically demonstrated effectiveness for your specific digestive concerns.

In summary, while probiotics may help some people alleviate gas and other digestive issues, the effects may vary based on the individual’s gut microbiome and specific probiotic strains. It’s essential to choose a suitable probiotic product and consult with your healthcare provider to address your specific digestive needs adequately.

Other Health Benefits and Side Effects

Immune System Support

Probiotics can contribute to maintaining a healthy immune system. By promoting a balanced gut microbiome, the presence of beneficial bacteria works to keep harmful pathogens in check. Incorporating probiotics into your diet may also help reduce the frequency and severity of certain common illnesses like the cold and flu 1. However, it should be noted that not all probiotic strains provide the same level of support, and more studies are still necessary to establish the full extent of these benefits.

Mental Health and Brain Function

Research has indicated a potential connection between gut health and mental well-being. Probiotics could positively influence brain function by improving the production of neurotransmitters and reducing inflammation in the gut-brain axis 2. Therefore, taking probiotics may potentially alleviate symptoms of mood disorders like anxiety and depression. Nevertheless, it’s essential to acknowledge that the full scope and effectiveness of probiotics in mental health are not yet fully understood.

Skin Issues and Allergies

Some evidence suggests that probiotics can help improve certain skin conditions and allergies. By modulating the immune response, they may reduce inflammation and offer relief for skin issues like eczema and dermatitis 3. Moreover, probiotics might help with allergies by promoting tolerance to allergens and reducing the likelihood of developing allergic reactions. However, it is important to remember that different probiotic strains might have varying effects, and further research is needed to confirm the effectiveness of probiotics for these issues.

Weight Management

Probiotics may assist in weight management by influencing digestion, energy metabolism, and appetite regulation 4. They could help in reducing the absorption of dietary fat and enhancing the elimination of excess fat. However, the impact on weight loss is considered modest and should not be solely relied on for managing weight. Keep in mind that specific probiotic strains might be more effective in weight management than others, and a balanced diet and regular exercise should always be the foundation of a healthy lifestyle.

While probiotics can offer several health benefits, it’s crucial to remember that they may also cause temporary side effects, such as gas and bloating 5. These side effects are generally mild and subside over time, but if they persist or worsen, consult a healthcare professional.



Common Probiotic Sources

In this section, we’ll explore some common sources of probiotics and how they can help you maintain a healthy gut. We’ll dive into three sub-categories: Yogurt and Dairy, Fermented Foods, and Supplements.

Yogurt and Dairy

Yogurt is one of the most popular and accessible sources of probiotics. It is made through the process of fermenting milk with the help of beneficial bacteria, usually Lactobacillus and Bifidobacterium. These bacteria help to break down lactose and can aid in digestion, making yogurt a great option for those with lactose intolerance. Make sure to choose yogurt with active or live cultures for the most probiotic benefits.

Aside from yogurt, other dairy products like kefir, a fermented milk drink, also contain beneficial probiotics. Kefir is similar to yogurt but has a thinner consistency and a slightly tangier taste. It can be consumed on its own or used in recipes like smoothies, sauces, and dressings.

Fermented Foods

Fermented foods are another excellent way to incorporate probiotics into your diet. Some popular fermented foods include:

  • Sauerkraut: A classic German dish made from fermented cabbage, it contains Lactobacillus bacteria that promote gut health.
  • Kimchi: A traditional Korean side dish made with fermented vegetables, typically cabbage and radish, and various seasonings. It is rich in Lactobacillus and other probiotics.
  • Tempeh: A plant-based protein made from fermented soybeans, tempeh contains helpful bacteria that aid digestion.
  • Miso: A Japanese seasoning made from fermented soybeans, rice, or barley, miso can be used to make soup or added to various dishes for extra flavor and probiotics.

Include these fermented options in your meals to give your gut a healthy boost of probiotics.


If you find it difficult to incorporate probiotic-rich foods into your diet, supplements can be a practical alternative. Probiotic supplements are available in various forms like capsules, tablets, and powders, and they contain a mix of beneficial bacteria strains. It’s essential to choose a high-quality probiotic supplement from a reputable brand.

Remember to consult your healthcare provider before taking any supplements, especially if you have any underlying health conditions or concerns. They can guide you on the right dosage and strains for your individual needs.

By including probiotic sources such as yogurt, dairy, fermented foods, and supplements into your daily routine, you can help support your gut health and potentially alleviate gas-related issues.


In your exploration of probiotics and their potential impact on gas, it’s important to understand that the efficacy of probiotics on bloating symptoms has not been consistently proven1. Some studies suggest that certain probiotics may help reduce gas production, while others show little to no effect.

Being confident and knowledgeable about this topic means acknowledging that probiotics can have different effects on each individual. Factors such as the specific strain of probiotic, dosage, and individual gut health can all influence whether or not probiotics might make gas worse for you.

To ensure a clear and neutral understanding, it’s crucial to consider the overall balance of gut bacteria. Probiotics that support the growth of beneficial bacteria, like bifidobacteria and lactobacilli, generally do not produce gas as a part of their fermentation process2. However, changes in gut bacteria populations can sometimes lead to temporary gas and bloating as your body adjusts to the new balance.

In summary, the relationship between probiotics and gas production can be highly individualized and is influenced by various factors. As you consider incorporating probiotics into your wellness routine, it’s essential to consult with a healthcare professional for personalized advice on the most suitable probiotic strains and dosages for your specific needs.
