It is always important to speak with your healthcare provider before adding supplements to your diet, especially if you are already taking a multivitamin with fiber in it and are pregnant.

While there are a good deal of fiber supplements options to choose from, we evaluated our choices based on the following criteria:. We prioritize companies that conduct third-party testing by credible institutions, such as USP and NSF , to ensure quality standards, and that what is on the product label is, in fact, what consumers are purchasing.

We reviewed marketing claims, ingredient lists and product quality, and prioritized companies that test for heavy metals, pesticide and herbicide contamination, among other items of concern.

We also highlighted companies that have strict internal quality control standards. We looked for different forms of fiber supplements, including soluble and insoluble fiber, and that could accommodate a range of budgets.

Although some foods, such as yogurt, kefir, sauerkraut, kimchi, and kombucha, are cultured with or have added probiotics, not all probiotic foods have enough live bacteria to survive the digestive system to provide health benefits.

They may also not have the right combination of strains to have a lasting impact on your gut health. On the other hand, a targeted probiotic supplement typically provides information on the CFU colony forming units per gram of live active microorganisms, which ideally will be 10 7 to 10 Finding a product with multiple strains of beneficial bacteria may be preferable since much of the research on common digestive issues, such as antibiotic-associated diarrhea and symptoms of irritable bowel syndrome, has used multi-strain products.

Adequate fiber intake is critical for digestive health; it keeps your gastrointestinal tract moving and your bowel movements regular and helps prevent chronic conditions. Increasing your intake of whole plant foods high in fiber, including whole grains, fruits, vegetables, legumes, nuts, and seeds, will provide a variety of insoluble and soluble dietary fibers, along with other crucial nutrients and beneficial plant compounds.

Some varieties of fiber offer more benefits than others, depending on your health goals. Prebiotic fibers work with the good bacteria in the digestive system by increasing their numbers and activity, including their ability to support immunity and maintain the gut barrier against harmful pathogens.

Prebiotics can also enhance the benefits of probiotics. Synbiotics are combination products that typically contain probiotics with a prebiotic, most commonly inulin, GOS, or FOS, that supports its beneficial health effects.

Research has found that synbiotics can enhance the microbiota, increasing beneficial Bifidobacteria and Lactobacilli. The goal of a synbiotic is to maximize the health impact of both the good bacteria and the prebiotic fiber by providing them together.

The amount of fiber in synbiotics varies, from very small quantities to larger amounts. Look for products that provide an optimal blend of probiotics with prebiotics.

The benefits of prebiotics for digestion go beyond those of standard fiber since they nourish beneficial bacteria, leading to a healthier, more balanced gut microbiome. Though humans have been consuming prebiotics in food since prehistoric times, research has uncovered their health benefits much more recently.

Well-studied prebiotics include inulin, galactooligosaccharides GOS , fructooligosaccharides FOS , and resistant starch. Prebiotics are found naturally in some plant foods like chicory, artichokes, asparagus, onions, garlic, whole wheat, oats, and barley, as well as in some processed foods with added prebiotics.

They are also available as supplements. Prebiotics target good bacteria in the colon, particularly Bifidobacteria. Research has found that consumption of the prebiotics inulin, FOS , resistant starch, and GOS significantly increased levels of Bifidobacteria and other beneficial gut bacteria.

The benefits to gut flora are specific to fiber with prebiotic effects. A recent analysis of randomized controlled trials found that prebiotic fiber supplements lead to significantly higher counts of Bifidobacteria and Lactobacilli than non-prebiotic fiber supplements.

These acids are critical in supporting the gut barrier and lowering colon pH. In turn, this promotes the growth of beneficial bacteria and inhibits gut pathogens. Enhanced production of short-chain fatty acids ensures adequate absorption of fluids and electrolytes in the colon and promotes intestinal motility.

Some prebiotics are more easily digested than others. Some, such as inulin and fructooligosaccharides, may not be well tolerated in larger doses and can cause digestive side effects such as gas, bloating, and diarrhea. These symptoms may be temporary as your digestive tract adapts.

To limit digestive upset, increase new fiber sources slowly and drink plenty of water to help move the fiber through your system. There are various prebiotic supplements available. A mixture of prebiotics may also most effectively support the beneficial actions of gut bacteria, like the production of short-chain fatty acids.

Omni-Biotic offers two different prebiotic options containing various beneficial fiber sources to meet your individual needs. Constipation, infrequent or difficult bowel movements, often of small, hard stools, is a common problem affecting both adults and children. A lack of fiber and fluids can lead to constipation.

Increasing fiber intake adds bulk and fluids to stool, making them softer and leading to easier passage and improved regularity. Insoluble fibers, such as those found in whole grains, vegetables, beans, nuts, and fruits, are most effective for adding bulk to stool.

For fiber supplements, however, experts frequently recommend soluble fibers such as psyllium for constipation and irritable bowel syndrome due to their ability to hold fluid and lead to softer stools.
