Best Insoluble Fiber Supplement For Constipation (10 Best Supplements)

Constipation is one of the most common gastrointestinal problems and is defined as incomplete and rare stools or difficult stools that last several weeks or more. It is the opposite of diarrhea.

In the United States, about 4 million people suffer from frequent constipation. Constipation is the most common gastrointestinal disease, which leads to 2.5 million visits to the doctor every year.

Fiber laxatives contain fibers that use water from your intestines to make your stool bulkier. A more extensive chair contracts the intestine and finally evacuates solid waste. It is essential to take bulk products with water to avoid side effects such as bloating and gas.

There are two types of Fiber Laxatives, one is soluble, and the other is insoluble.

Soluble fiber dissolves easily in water and breaks down into a jelly substance in a part of the gut called the large intestine. Insoluble fiber does not dissolve in water and remains intact when food passes through the gastrointestinal tract.

Insoluble fiber bulks up your stool and acts like a brush, sweeping through your bowels to get everything out and keep things moving. At the same time, The soluble variety absorbs water and forms a gel-like substance. This helps your stool pass smoothly through your bowels and improves its form and consistency.

This study has linked the increased intake of dietary fiber that can benefit several gastrointestinal disorders; one of them is constipation.

Many foods contain fiber, but especially good sources of fiber include :

There are two types of fiber: insoluble and soluble. Both types of fiber can benefit health.

Insoluble fiber does not dissolve in water, and this helps food pass through the digestive system. Insoluble fiber can help promote regular bowel movements. Foods such as brown rice, legumes, cauliflower, and spinach contain insoluble fiber.

Soluble fiber does dissolve in water. This type of fiber can help lower blood sugar levels and reduce cholesterol. Foods like oatmeal, lentils, blueberries, and apples contain soluble fiber.

Both types of fiber can help with bowel regularity, but they may also provide health benefits for people who have or are at risk of developing the following conditions:

• heart disease
• metabolic syndrome
• type 2 diabetes
• diverticulitis

Fiber may also aid in weight management. A 2019 study suggested that eating dietary fiber, independent of other factors such as calorie intake, helps promote weight loss in adults with overweight or obesity eating a lower-calorie diet.

Fiber also provides the body with prebiotics. Prebiotics are substances that feed the “good” bacteria in the gut.

According to the Harvard School of Public Health, the recommended daily fiber intake per day is 20–30 grams (g). However, many people in the United States only consume around 15 g. A fiber supplement may help people who find it difficult to eat more fiber. However, fiber supplements are not a substitute for a balanced diet.

Adding more water alongside increased fiber intake can also help to reduce constipation.

The supplement market is not heavily regulated, and companies can make unsubstantiated claims. A person should discuss with a doctor whether a product is right for them.
