Between supporting healthy digestion, heart health, and weight management, as well as being linked to a reduced risk of stroke, certain cancers, and diabetes, fiber plays some impressive roles in the body. As an indigestible carbohydrate, fiber plays an important role in our overall health. However, since approximately 95% of all American adults and children don’t consume the recommended amounts of fiber, supplementation is sometimes needed to bridge the gap.

Most adult women should try to consume between 21 to 25 grams of fiber a day, and most men should shoot for an intake between 30 to 38 grams. Some foods that include fiber include fruits, vegetables, beans, and nuts. Inadequate intake of fiber can result in constipation, weight gain, and blood sugar spikes, but overall outcomes will vary from person to person.

You’ll find different types of fiber in fiber supplements.

Fiber supplements come in diverse forms, each offering unique benefits and applications. Some fibers that are found in fiber supplements include:

• Psyllium husk, derived from the seeds of the Plantago ovata plant, is renowned for its ability to soften stool and alleviate constipation.
• Inulin, extracted primarily from chicory root, doubles as a prebiotic, fostering a healthy gut microbiome.
• Methylcellulose is a synthetic option that resists fermentation in your gut, reducing the likelihood of bloating or gas.
• Acacia powder, derived from the sap of the Acacia senegal tree, is a soluble fiber that helps improve digestive health by promoting regular bowel movements.

As is the case when choosing any supplement, your fiber supplement should be third-party verified. This ensures that the product has undergone rigorous scrutiny and testing by an independent entity, offering reassurance regarding its purity, safety, and the accuracy of its ingredient labels.

If your healthcare provider told you to include a fiber supplement in your diet, here are 11 that are worth considering.

The 11 best fiber supplements you can buy:

NOW Organic Fiber 3

This fiber supplement contains 4 grams of fiber, with half being soluble and the other half being insoluble. Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract, potentially helping lower blood cholesterol and glucose levels, which can be beneficial for individuals with diabetes and heart disease. Insoluble fiber does not dissolve in water, and it adds bulk to the diet, aiding in the prevention of constipation. This balanced blend is made with organic golden flax meal, organic acacia, and organic inulin.

Bonus? This supplement also gives the body a boost of omega-3 fatty acids, a “healthy” fat that supports many aspects of our health, including our brain health.

Fiome Fiber Bites

These bites are pill and powder-free, made from ingredients like banana, dates, and chia seeds. Each bite provides 5 grams of fiber and only 2 grams of sugar.

OLIPOP

Who says you can’t get your fiber fix and drink a soda at the same time? OLIPOP is a unique soda that isn’t made with loads of added sugars or anything artificial (unlike many of the OG soda varieties). And when it comes to fiber, OLIPOP has an impressive 9 grams of prebiotic fiber per can, helping support a healthy gut microbiome.
