Probiotics versus Prebiotics: Which is Best for Your Health?
With the increased research on gut health, the benefits of probiotics and prebiotics are getting a lot more attention.
But what are probiotics and prebiotics, and is this something that you should be taking?
Probiotics are live microorganisms found in foods like yogurt and sauerkraut that improve gut health by balancing the digestive system. Prebiotics, on the other hand, are high-fiber foods that serve as food for these beneficial bacteria, enhancing their effectiveness.
So it is not probiotics versus prebiotics, but how prebiotic foods and fibers can enhance the beneficial probiotic bacteria.
For the best gut health, it’s important to include both probiotics and prebiotics in your diet. The synergy between prebiotics and probiotics ensures optimal digestive function and overall health, making neither superior to the other. It is their combined action that supports a balanced and healthy gut.
….. But if I had to choose a winner, it would be prebiotics, as these foods and supplements are going to have a bigger positive impact on your gut microbiome than most probiotic supplements.

Understanding Probiotics
Probiotics are live bacteria that support gut health. They can be found in various foods and supplements, each offering unique benefits.
Defining Probiotics
Probiotics are live microorganisms that provide health benefits when consumed in proper amounts. They are often referred to as “good bacteria.”
These microorganisms help maintain the balance of bacteria in the gut. Common types of probiotics include Lactobacillus and Bifidobacterium, which are known for their positive effects on digestion and overall gut health.
Health Benefits of Probiotics
Probiotics offer various health benefits. They can aid in digestion, improve nutrient absorption, and help maintain a healthy balance of gut bacteria.
Some studies suggest that probiotics might boost the immune system and reduce the risk of certain digestive disorders, such as irritable bowel syndrome (IBS) and diarrhea caused by infections or antibiotics.
Probiotics may also help in managing symptoms of allergies and eczema in children.
Common Probiotic Foods
Probiotics can be found in several fermented foods. Yogurt, for instance, is a popular source that contains Lactobacillus strains. Sauerkraut and kefir are also rich in various probiotic cultures.
Other sources include kimchi, miso, and tempeh. These foods undergo a fermentation process that encourages the growth of beneficial bacteria, making them a valuable part of a healthy diet.
Probiotics in Supplements
Probiotic supplements are available if you are not getting enough probiotics from your diet, or if you have a condition like IBS, leaky gut or diarrhea that may benefit from specific species of probiotics.
These supplements come in various forms, some need to be kept chilled while some are stable at room temperature.
It’s important to choose a high-quality supplement that specifies the strains of bacteria it contains. It is also important to do your research or consult with a professional to make sure you get the right strain that you need for your health.
Prebiotics and Their Role
Prebiotics are essential for maintaining a healthy gut. They primarily act as food for good bacteria and are found in many common foods.
What Are Prebiotics?
Prebiotics are types of dietary fiber that humans cannot digest. They serve as nourishment for the good bacteria in the gut.
These fibers pass through the upper part of the gastrointestinal tract and remain undigested because the human body lacks the enzymes to break them down.
When prebiotics reach the colon, they are fermented by the gut microbiota, which includes beneficial bacteria. This fermentation process helps the growth and activity of these good bacteria, improving digestive health overall.
Prebiotics in Diet
Incorporating prebiotics into the diet can be straightforward since they are present in various natural foods. They are predominantly found in high-fiber foods like:
- Whole grains
- Bananas
- Artichokes
- Onions
- Garlic
Eating a diet rich in these foods can help maintain a balanced gut microbiome. It’s also possible to find prebiotics in certain supplements, which can be an additional source if dietary intake is insufficient.
Sometimes prebiotic supplements like PHGG (Sunfiber) are better than high fiber foods if you are recovering from SIBO as you can control the amount you get, starting small and slowly increasing the dose.
Benefits to Gut Microbiome
Prebiotics play a critical role in nurturing gut health. By serving as food for the good bacteria, they help increase the number and variety of beneficial microorganisms in the gut. Some key benefits include:
- Improved digestion
- Enhanced immune response
- Better absorption of minerals like calcium and magnesium
- Possible reduction in the risk of certain gut-related diseases
The presence of prebiotics also creates a more favorable environment for probiotics to thrive, making the gut microbiome more robust and balanced.
If you include plenty of prebiotic rich foods in your diet, and variety is the key, then you may not need to take probiotics.
Food Sources of Prebiotics
Several foods are rich in prebiotics, ensuring they can be easily integrated into daily meals. Some notable sources include:
- Whole grains: Foods like oats, barley, and wheat contain high amounts of fiber.
- Bananas: Especially green bananas are known for their prebiotic properties.
- Artichokes: Both Jerusalem and regular artichokes are excellent sources of inulin.
- Greens: Foods like spinach and kale.
- Onions and Garlic: Common kitchen staples rich in inulin, a type of prebiotic fiber.
- Chicory root: Often used as a coffee substitute, this root is also rich in inulin.
Including these foods in the diet can naturally boost intake of prebiotics, supporting overall gut health.
Comparing Probiotics and Prebiotics
Probiotics and prebiotics both play crucial roles in maintaining gut health, but they serve different functions.
Understanding these differences, how they work together, and how to choose between them is essential for improving the gut microbiome.
Functional Differences
Probiotics are live bacteria found in certain foods and supplements. They introduce beneficial bacteria into the gut, which can help balance the gut microbiome and improve digestion.
Prebiotics, on the other hand, are non-digestible carbohydrates that act as food for these beneficial bacteria. Foods like whole grains, bananas, onions, and garlic are rich in prebiotics.
While probiotics work by adding good bacteria to the gut, prebiotics support the growth and effectiveness of these bacteria. Both are essential, but they function differently in promoting a healthy gut environment.
Synergistic Effects
Probiotics and prebiotics work better together, creating what’s known as synbiotics. Synbiotics combine both elements to foster a more diverse and balanced gut microbiome.
For instance, prebiotics like inulin can be packaged with probiotics in certain supplements. This combination ensures that the good bacteria have plenty of food, which helps them multiply and thrive.
For example the Pendulum probiotics contain inulin to enhance their effectiveness.
Including both probiotics and prebiotics in the diet can enhance digestion, boost the immune system, and promote overall gut health.
Fermented foods high in probiotics and high-fiber foods rich in prebiotics can be a natural way to achieve these benefits.
Choosing Between Probiotics and Prebiotics
Deciding whether to focus on probiotics or prebiotics depends on individual health needs. If someone has an imbalance in their gut microbiome, adding more probiotics might be beneficial.
For those looking to support the bacteria already in their gut, increasing prebiotic intake can be more effective. Good choices include bananas, greens, and artichokes.
If you have Small Intestinal Bacterial Overgrowth (SIBO) then you may have to do a short term low FODMAP diet, this is a diet that is low in prebiotics to prevent bacteria overgrowth in the small intestine.
Prebiotic And Probiotic Effects On Health And Diseases
Probiotics and prebiotics affect various health conditions differently but significantly. They influence digestive disorders, chronic diseases, immunity, and mental health.
Digestive Disorders
Probiotics and prebiotics are commonly used in managing digestive disorders like irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).
Probiotics introduce beneficial bacteria into the gut, helping balance gut flora. This may reduce inflammation and symptoms like bloating and gas.
Prebiotics, which are non-digestible fibers, promote the growth of beneficial bacteria already present. This supports a healthy gut environment.
Studies show that both can alleviate symptoms of IBS, improve bowel regularity, and enhance nutrient absorption, ultimately benefiting overall digestive health.
Chronic Diseases and Immunity
Chronic diseases such as obesity, diabetes, and cardiovascular conditions are influenced by the gut microbiome. Probiotics can improve immune system responses and reduce systemic inflammation, potentially lowering the risk of these diseases.
Prebiotics, by fostering beneficial bacteria, also help modulate the immune system. Enhanced immunity means a better defense against infections and a potentially lower risk of autoimmune disorders.
Research highlights that a balanced gut microbiome contributes to maintaining body weight, regulating blood sugar, and reducing bad cholesterol levels.
Mental Health Correlations
The connection between the gut and the brain, known as the gut-brain axis, shows that gut health impacts mental health.
Probiotics can influence mood and mental health conditions like depression and anxiety by producing neurotransmitters such as serotonin.
Prebiotics support this process by feeding the beneficial bacteria that produce these neurotransmitters. This can lead to improved mood and reduction in depressive symptoms.
Studies have shown that changes in gut flora can directly affect stress responses, highlighting the potential for probiotics and prebiotics in mental health management.
Safety and Recommendations
Probiotics and prebiotics offer various health benefits but their use should be guided by specific safety recommendations. It’s important to understand potential side effects, interactions with other substances, and how to optimize intake.
Overall they are very safe, especially probiotics but they do have the potential to cause a flare in SIBO symptoms if introduced too quickly
Consulting Gut Health Specialists
Eating a diet rich in prebiotic foods is essential for a healthy microbiome, a wide variety of foods is important too and this encourages a diverse microbiome.
Probiotics are not all created equal, some species are very specific for certain conditions, and the quality between different companies varies greatly.
Most doctors are not experts in probiotics, so they are probably not the best people to ask in regards to which one you should take.
Doing an advanced stool test like the Vibrant Wellness Gut Zoomer can help to identify which species of probiotics you are missing, this can help to guide you on the best probiotic supplement to take.
Side Effects and Interactions
Some people might experience mild side effects when taking probiotics or prebiotics, such as bloating, gas, or diarrhea. These side effects are usually temporary and subside once the body adjusts.
Probiotics can reduce the negative side effects of antibiotics, the research shows that taking probiotics with antibiotics can help to reduce the negative side effects of antibiotics.
