FAQ
What exactly are prebiotics and why do they matter for my health?
To understand why these nutrients are so vital, it helps to think of prebiotics as specialized fuel. Essentially, prebiotics are fibers that the human body cannot digest, but the bacteria in your gut love to eat. When you get prebiotics through your diet, you are feeding the beneficial effects of your gut microbiota. They play a crucial role in overall health because, without them, the probiotics (the good bacteria) in your system wouldn’t have the energy to offer health benefits or maintain a balanced gut health environment.
What is the main difference between prebiotics and probiotics?
The difference between prebiotics and probiotics is quite simple but important. Probiotics are live bacteria that are naturally found in fermented foods like Chobani yogurt or GT’s Living Foods kombucha. On the other hand, prebiotics are nutrients—specifically non-digestible fibers—that act as a source of prebiotics for those live organisms. While probiotics are live microorganisms, prebiotics are the “food” that helps them grow. Both prebiotics and probiotics work in tandem to support your digestive system.
How do prebiotics work to support my digestive system?
The prebiotics work through a natural fermentation process. As they travel to the lower digestive tract, the bacteria in your gut ferment these fibers. This process leads to the production of short-chain fatty acids, such as butyrate, which provide energy to the cells lining your colon. By choosing to ferment the prebiotics, your gut bacteria can thrive, which prebiotics help maintain a stable and healthy gut microbiota. This chemical reaction is one of the primary health effects that leads to better digestion.
What are the most common health benefits of prebiotics?
There is significant evidence that prebiotics can provide a wide range of beneficial health effects. The health benefits of prebiotics include improved digestive function, and prebiotics may help manage symptoms of irritable bowel syndrome (IBS). Furthermore, prebiotics may improve mineral absorption, particularly calcium, which supports bone health. Some studies also suggest prebiotics can help with weight management and even enhanced immune system function. Beyond the gut, prebiotics also contribute to better metabolic health.
Which foods are naturally high in prebiotics?
A: Foods high in prebiotics include many common kitchen staples. If you are looking for sources of prebiotics includevegetables like garlic, onions, leeks, and Jerusalem artichokes. Other foods like bananas, oats, and legumes are also rich in prebiotics. Eating foods high in prebiotics is often the best way to start incorporating prebiotics into your diet naturally. Many people also enjoy prebiotic-rich foods or supplements like Bob’s Red Mill Potato Starch or chicory root to boost their intake.
Can I take prebiotics and probiotics together?
Absolutely! In fact, prebiotics and probiotics together are often referred to as “synbiotics.” When probiotics and prebiotics may be taken at the same time, the prebiotic helps the probiotic survive the journey through the stomach. The use of prebiotics and probiotics in combination can lead to more significant benefits of prebiotics and probiotics than taking either alone. Many products from brands like Seed or Garden of Life are formulated so that prebiotics and probiotics also work synergistically for maximum gut health.
Are there any side effects of prebiotics I should know about?
While they are generally safe, prebiotics may cause some mild effects like gas, bloating, or abdominal discomfort.

To avoid these potential side effects of prebiotics, it is best to start with a small amount of prebiotics and gradually increase your intake of prebiotics. If you notice side effects of prebiotics, simply reduce your dose of prebiotics until your body adjusts. Significant risk of side effects is rare if you transition slowly.
What is the recommended dosage of prebiotics per day?
There isn’t one universal dosage of prebiotics, but most experts suggest an amount of prebiotics between 3 to 5 grams of prebiotics daily for beginners. Once your system is used to it, a standard dosage can reach 10 to 15 grams per day. If you take a prebiotic supplement, like those from Benefiber or Metamucil, always check the label for the specific grams of prebiotics a day provided per serving. Consuming prebiotics in excess too quickly is what usually cause certain side effects.
Is it better to take a prebiotic supplement or eat prebiotic foods?
Both have their advantages. Prebiotic foods provide additional vitamins and minerals, while a prebiotic supplement offers a concentrated, measurable dose of prebiotics. If you find it hard to eat enough rich in prebiotics plants, you might take prebiotic supplements to fill the gap. However, adding prebiotics to your diet through whole foods is generally recommended as the primary source of prebiotics. Whether you choose foods or supplements, the goal is to ensure your gut bacteria are well-fed.
Can prebiotics help with specific health conditions like IBS?
Yes, prebiotics may help improve symptoms for those with irritable bowel syndrome, though it depends on the type of prebiotic. For some, inulin or FOS may actually trigger symptoms, while others find that prebiotics can help regulate bowel movements. If you have health conditions like IBS, it is important to take prebiotics under the guidance of a professional to find the right intake of prebiotics that works for your specific gut microbiota without causing a flare-up.
