What Is The Best Insoluble Fiber Supplement?


Last Updated on

Fibers are of two types; insoluble fiber and soluble fiber. While the soluble fiber is commonly found in fiber supplements, it’s a bit difficult to find a supplement with just insoluble fiber content, as most of the popular ones are majorly composed of soluble fibers.

I have gone the extra mile in reviewing the best insoluble fiber supplement on amazon. Most of them contain a mix of soluble and insoluble fiber, but the percentage of insoluble fiber outweighs the soluble fibers in all of the recommended products.

For education purpose; the major difference between soluble and insoluble fiber is that; the former dissolves in water, thereby reducing the rate of digestion. Insoluble fiber on the other hand does not dissolve in water, they make stool bulky and aid movement through your digestive tract.

If you have constipation, or poor bowel movement, then consuming more of insoluble fiber would help greatly.

Be it irritable bowel syndrome (IBS), constipation, or you’re trying to beat hunger by loading up on fiber, these supplements would serve your fiber need adequately.
