FAQs Regarding Prebiotin® Prebiotic Fiber

A prebiotic is a special type of plant fiber that selectively nourishes the good bacteria in the gut which, in turn, produces many health benefits.

 Learn more about how prebiotics work.

Probiotics are live bacteria most commonly found in yogurt, other dairy products, and supplements that can add to the “good” bacteria in our digestive systems. Prebiotics, on the other hand, are not live.  They are a special type of fiber from certain food sources that “feed” the good bacteria already in the gut so the bacteria can easily multiply in the colon.

An easy way to understand the difference is to consider the probiotic the seed, while the prebiotic is the fertilizer that feeds the seed and helps it to grow and thrive. Prebiotin prebiotic fiber can be used without probiotics since it nurtures the good bacteria already in the gut.

Prebiotin contains two types of indigestible carbohydrates or fibers: oligofructose and inulin. Together they are called oligofructose-enriched inulin (OEI). Both types of fibers are derived from the chicory plant, which has high concentrations of the purest prebiotic fiber. The fibers are mixed together in a carefully designed formula, using NO additives, to feed the “good bacteria” residing in the large intestine.

Some people are concerned that oligofructose (one of the key ingredients) is a sugar such as fructose. However, it is a sugar only in a chemical sense. Both oligofructose and inulin (the other main ingredient) do not act as sugars. As fibers, they are not absorbed by the small intestine as digestible food and add no calories to the diet.

Why is Prebiotin® called a “full-spectrum” prebiotic fiber?

Prebiotin contains two prebiotic fibers that are refined from chicory root, which has high concentrations of pure fiber: oligofructose, also known as FOS, fertilizes beneficial bacteria in the right side of the colon. Inulin by itself is a longer, more complex fiber that acts mostly in the left side of the colon. Prebiotin is the only prebiotic supplement to combine inulin and oligofructose (OEI) into a carefully designed formula that nourishes the good bacteria throughout the whole colon.

Since Prebiotin is pure prebiotic soluble fiber, you do not need a large amount. For the first week, start with a half of the small scoop in your container of Prebiotin (which equals about ½ cooking teaspoon of the powder) or half of a 4 gram fiber stick. A scoop is 4 grams of powder; fiber sticks come in 2 and 4 gram units. This would be equavalent to about 1/2 gram to 2 grams to start. 

If there is no unusual abdominal bloating, cramping, or excess flatus (gas), increase the dose to a full scoop or a whole fiber stick, twice a day for a total of 8 grams per day. Some individuals with gastrointestinal illness take twice this amount. Build up slowly to determine what amount brings the best results in your own system. 

No. There are no serious side effects from taking Prebiotin. As your body adjusts to the fiber, you will experience less digestive upset and numerous health-boosting benefits. Be aware that the product is sourced from chicory root. However any allergies to chicory are extremely rare. You should also be aware that our Regularity formula includes wheat bran, and is not gluten free.

Some people experience excess gas or flatus initially. To avoid this, it is best to start taking a small amount daily (for example, a ½ scoop or fiber stick per day for the first week), then slowly to build up to the desired amount. At a certain level, many people will notice that their intestinal gas no longer has an unpleasant odor. This is because acidity has increased in the colon, and the bacteria that make the smelly sulfide gases no longer grow. This is a good indication that you are taking the proper amount for your gut.

By taking Prebiotin, you nourish beneficial gut bacteria and improve your health. You’ll notice improved regularity. If you suffer from a lower GI condition such as irritable bowel syndrome (IBS), you may notice a reduction in uncomfortable symptoms and conditional improvement over time.

The fiber in Prebiotin has also been clinically proven to increase the bioavailability of calcium already in your diet, making you less susceptible to osteoporosis. Recent studies have proven that Prebiotin can also strengthen the immune system, help with weight and appetite control, and improve mental health with the impact on the gut-brain connection. Because so much of our good health starts in the gut, there are so many benefits that come from feeding the good gut bacteria.

Can I feel Prebiotin® prebiotic fiber working in my body?

Yes. There are some people who will get a surprisingly rapid improvement in their sense of well-being, with decreased appetite and an improved bowel pattern. However, because Prebiotin prebiotic fiber addresses the underlying cause of health complaints by improving the mix of bacteria in the colon, it may take several weeks to several months to notice a change in health and well-being. 

Without enough prebiotic fiber, the “bad” bacteria may take over the digestive system and cause dysbiosis—symptoms like constipation, diarrhea, and other digestive distress. Studies have found that joint pain and even depression can be related to the mix of bacteria in the colon. Using Prebiotin for several months has been shown to diminish these symptoms and boost the immune system.

If I am healthy, are there any benefits to taking Prebiotin® prebiotic fiber?

Absolutely! The standard Western diet has become markedly deficient in prebiotic fibers. Our ancestors, who relied on grains, berries, and especially root vegetables for nutrition, ingested large quantities of these beneficial prebiotics. Unfortunately, modern food production, the industrialization of farming, the cheap availability of animal meats, and a cultural preference for fast, processed foods have all but eliminated these healthy fibers from our diet. A regular dose of Prebiotin prebiotic fiber returns the gut to a more healthy, natural state.

From a medical and scientific standpoint, colon cleansing makes no sense. You can never rid your colon of bacteria, nor should you ever want to. Most colon cleansing products simply empty out the lower portion of the colon or encourage large, bulky stool. They do not provide the nourishment and support for the growth of healthy bacteria colonies in the colon that Prebiotin offers.

Rather than cleansing the colon, a better choice is to use Prebiotin prebiotic fiber to bring the bacteria into a healthy balance that boosts the immune system and helps with regularity.

Most of us have some “bad” bacteria in our colon. E. coli is a common example. These types of bacteria produce toxins (also called “endotoxins” in medical settings) or substances that are poisonous to humans. When too many “bad” bacteria grow in your colon, then the lining of the gut becomes weaker, and the toxins from the bacteria can move more easily through the colon wall and into the blood stream. This can cause a wide range of health problems, from pain in the joints and food allergies, to autoimmune diseases like celiac and Crohn’s disease and even depression.

It is almost impossible to get rid of most of these bacteria completely. However, by using Prebiotin, you will feed the good bacteria and restrict the growth of the undesirable bacteria. The more you use Prebiotin, the less the bad bacteria will become a problem.

The gut microbiota, or flora, is the medical term for the incredible mix of bacteria and other microbes such as fungi and viruses that make up your digestive tract, from your esophagus to your colon. The greatest number of these microbes are in your colon. That can be a good or bad mix depending on the diet you eat, and if your diet includes enough prebiotic foods to stimulate the growth of “good” bacteria. Prebiotin prebiotic supplement is a pure prebiotic and stimulates the growth of good microbiota.

FAQs Regarding How and When to Take Prebiotin

Prebiotin prebiotic fiber product readily dissolves in any hot or cold liquid with stirring. It can also be sprinkled on to any foods such as cereal, soups, sauces, salads, and vegetables. It has a very slight natural sweetness, which can complement foods. To reach the full benefits of taking Prebiotin, it is best to take it daily and at a consistent time of day. The specific time of day is a matter of personal preference. Really the options are only limited by your imagination and what works best for you and your gut.

Prebiotin has no known interactions with medications. It is just fiber, a food source. However, you should always check with your physician about the impact of any supplement.

Children of any age can take Prebiotin prebiotic fiber to help them develop and maintain a healthy digestive system. Inulin and oligofructose, the main ingredients in Prebiotin, are dietary fibers that are safe for children of all ages and even infants. It is best to start with very small amounts and build up the daily dose slowly based on the age and weight of the child. Prebiotin supports the development of a healthy immune system and can reduce problems with constipation.

It is always helpful to discuss Prebiotin and all supplements with your child’s pediatrician.

Antibiotics destroy good as well as bad bacteria in the colon, even while they are clearing up an infection. It is therefore best to continue the daily routine of taking Prebiotin prebiotic fiber to ensure that new, healthy bacteria colonies are being nourished and re-established to replace the bacteria that was destroyed by the antibiotics. It is important to provide extra support for the growth of new, helpful bacteria since even a single course of antibiotics can have an impact on the gut for over two years.

Prebiotin® Prebiotic Fiber and Specific Health Conditions

Yes. Prebiotin prebiotic fiber products have been independently tested and are gluten free, with two exceptions:  Prebiotin Regularity and Prebiotin Heart Health. The main ingredient in Prebiotin, chicory root, does not contain gluten. Prebiotin Prebiotic Fiber is an excellent product for individuals with Celiac disease. It can replace the health-boosting fiber that is also eliminated when wheat products are removed from one’s diet.

It is now well-established that Crohn’s disease begins when the bowel wall weakens and certain colon bacteria invade it, causing inflammation. In addition, analysis of the gut bacteria in Crohn’s patients shows a less healthy mix than that of individuals without the disease. Studies indicate that Prebiotin strengthens the gut wall by stimulating the growth of good bacteria. It is suspected that these desirable bacteria can be helpful in the dietary management of Crohn’s  disease.

UC begins in the left side of the colon and rectum. Normally, the colon contents here are neutral, neither acid nor alkaline. Prebiotin helps to acidify the bowel in this area, which can prevent ulceration in the bowel wall, the hallmark of UC. With UC, as with many bowel conditions and diseases, research has found that the “bad” bacteria predominate in the colon. Early studies indicate that with Prebiotin, the good bacteria grow, and symptoms of digestive disorders like UC improve.

Obesity, processed meats, and alcohol have been associated with increased risk of polyps or tumors in the colon. On the other hand, fiber, garlic, milk, and calcium have shown protective effects. The activity and makeup of the bacteria is also important to reduce the number of polyps or tumors. Researchers have found that eating a high fiber diet and using a prebiotic like Prebiotin reduces the risk for polyps and cancer in the bowel.

When undesirable bacteria predominate in the gut, the lining of the gut weakens and allows certain bacteria and their byproducts, endotoxins or toxins, to move through the bowel wall. From there, they may enter the blood stream, reach the liver, and then move throughout the entire body, causing health problems (including joint pain, asthma, Type 1 diabetes, allergies, and other health conditions). Taking Prebiotin prebiotic fiber can improve the bacterial makeup in the gut and actually strengthen the bowel wall, which can in turn stop toxins from moving into the blood stream.

Overweight people have an abnormal mix of bacteria in the colon. Prebiotin prebiotic fiber helps to nurture the good bacteria so they flourish and improves the bacterial mix in the gut. A healthy mix of bacteria stimulates the production of hormones which dull the appetite and provide a sense of fullness. In this way, taking Prebiotin can help with weight loss and obesity.

IBS is a functional bowel disorder consisting of abdominal distension and fullness, recurrent distress or discomfort, and changes in flatulence and stool pattern. Persons with IBS have been found to have an abnormal bacterial mix within the colon. Prebiotin can improve the bacterial mix in the colon and may help relieve some of the symptoms of IBS. It is best to start by taking low doses of Prebiotin, then increasing the dose gradually, depending on symptoms of bloating and gas.

There is no known cause or cure for autism. However, researchers have found striking differences in the microbiome of children with autism. They often have fewer types of bacteria and a less healthy mix of bacteria, making the gut more susceptible to attack from disease-causing pathogens.

Accordingly, the most common complaint of children with autism is “tummy troubles”—everything from pain to diarrhea and constipation. Autistic children with tummy troubles can benefit from taking Prebiotin prebiotic fiber to improve the mix of bacteria in their digestive systems. This may relieve some of the gastrointestinal distress and related behavioral problems, learning difficulties, and issues with sleep.

Research has shown that type 2 diabetes is almost always associated with higher levels of undesirable bacteria in the gut. This unfavorable mixture of bacteria, called dysbiosis, leads to chronic inflammation, the main cause of diabetes-related injuries to the blood vessels. Studies have shown that regular use of Prebiotin Prebiotic Fiber, along with a high fiber diet, can reduce inflammation in the body and reduce the risk of developing diabetes and its impact.
