5 Important Fiber Supplements

Fiber is an essential nutrient that is needed for healthy digestion. High-fiber diets are known to have many benefits for your health, including improved heart health. Fiber is actually a type of complex carbohydrate that the body is unable to digest. People usually derive all the fiber they need from food, but it is also possible to get the required amount of fiber by taking fiber supplements. Here are some of the most important fiber supplements that are available.

What Is Fiber & What Are Its Benefits?

Fiber helps improve bowel regularity and also provides many health benefits for those who already have or have a high risk of developing the following medical conditions:(6)

If you are not getting sufficient fiber from food sources, you can take fiber supplements, but only after consulting your doctor.

How to Select a Fiber Supplement?

With so many brands of fiber supplements available on the market today, it can quickly become overwhelming to choose one. It is essential to keep in mind that you have to consider your overall diet and your medical history to determine whether you even need a fiber supplement or not. Also, go through the type of fibers and their benefits to decide what type of fiber supplement would be ideal for you.

For example, fiber supplements that contain psyllium fiber are known to lead to better glycemic control, which is especially helpful for those who have type 2 diabetes. Psyllium has also been found to help regularize stools in people having Irritable Bowel SyndromeConstipation (IBS-C).(14)

Another way to decide which fiber supplement would be ideal for you depends on whether you support organic products. In this case, you can buy a functional food fiber supplement that has the USDA (United States Department of Agriculture) organic certification. Some companies might also have a certified B corporation designation that implies that they meet the high standards of social and environmental responsibility. So if this is something that appeals to you as a consumer, you can consider fiber supplements manufactured by companies like Garden of Life.

Remember, though, that buying a fiber supplement should not burn a hole in your pocket. So it is vital to select a product that falls within your budget, especially if you intend to use it in the long run.

At the end of the day, it is important to select a fiber supplement that best suits your needs, whether it is taking care of occasional constipation, controlling blood sugar levels, or reducing cholesterol levels.
