What is Fiber?

Fiber is a form of carbohydrate. However, it cannot be digested by the body. Fiber comes in two different forms—soluble and insoluble. 

Soluble fiber can be found in the following foods:

  • Oats
  • Oat bran
  • Dried beans
  • Dried peas
  • Nuts
  • Barley flax
  • Oranges
  • Apples
  • Carrots

Insoluble fiber is found in:

  • Green beans
  • Dark green leafy vegetables
  • Fruit skins
  • Root vegetable skins
  • Whole-wheat products
  • Seeds
  • Nuts

For optimal gut health, you need both types of fiber. 

What are the Benefits of Taking a Fiber Supplement?

For the last 150 years, grains have become a Western world diet staple. However, it comes at the expense of fiber, which is being consumed at chronically low levels by many people. 

An immediate result of lack of fiber in the diet is constipation. Apart from the discomfort it brings, it also makes it extremely difficult to eliminate toxins from your body. 

Fiber Fills You Up

Fiber is a great way to keep yourself full. That is because it adds bulk to your diet without adding extra calories. Not only will it help you feel satiated sooner, but it will also keep you feeling full for longer as it takes longer than other foods to move through your system. Fiber stimulates receptors that send messages to your brain that tell you to stop eating. 

Fiber Reduces Insulin Levels

When soluble fiber absorbs water, it forms a gel in the lower intestine, slowing blood sugar absorption. This, in turn, leads to lower insulin levels, which makes you less likely to store body fat.

Fiber Improves Energy

Combining fiber and lean protein at every meal and snack time will help you maintain stable blood glucose levels. As a result, you will have a more steady supply of energy. However, consuming refined carbs can spike your blood sugar levels. This gives you an intense surge of energy, which is inevitably followed by an energy crash that not only makes you feel lethargic but also causes a craving for more refined carbs. 

Fiber Improves  Elimination

When you consume a healthy amount of fiber, you will find yourself visiting the bathroom more often. That’s because fiber adds bulk to your stool. It also goes a long way to relieve you of gas and bloating problems, including irritable bowel syndrome.

Improves Skin Quality

Fiber is like a sponge in that it absorbs toxins that are coursing through the blood. When these are removed, they will no longer travel to your pores, resulting in smoother skin.

How Much Fiber Should You Take?

According to the American Academy of Nutrition and Dietetics, men should consume 38 grams of fiber per day. Women should take 25 grams per day. The Academy has also pointed out that, in 2015, just five percent of the American population were meeting that level, with the average intake, for both men and women, being just 17 grams. 

How To Take a Fiber Supplement

Whole foods are the best source of fiber. You should focus on eating whole grains, vegetables, nuts, and fruit. With so many people not meeting the recommended daily fiber intake goal, nutritionists recommend taking a supplement to bridge the gap.

If you are taking other medications, you should check with your doctor to ensure your fiber supplement will not interfere with them. 

It is important to stay hydrated when supplementing with fiber. You should take your fiber supplement with an eight-ounce glass of water.

What to Look For in a Fiber Supplement

Here are the things you should consider before buying a fiber supp:

Fiber Type

Check that the supplement contains both soluble and insoluble fiber. Both types are needed to benefit from the health benefits of adding more fiber to your diet.

Supplement Type

Fiber comes in several forms, from gummy bears, powders, and capsules. Choose what best suits your tastes and lifestyle. If you don’t like to swallow pills, for instance, you may be better off taking a powder or gummy bear form of fiber supplement. 

Supplement Quality

The FDA does not stringently oversee the supplement industry in the United States. You should, therefore, look for signs on the label indicating high production standards. It could include a Good Manufacturing Practices (GMP) label or a third-party tested sticker.

Cost

The best fiber supplements range between $0.34 and $1.99 per serving. The average cost is around 50 cents, which is what you should expect to pay.

How We Decided Our Picks

For our top 10 fiber supplements, we looked at several products and factors, including:

FAQs

Is it worth taking a fiber supplement?

Yes, it is worth taking a fiber supplement unless you are already meeting your recommended daily fiber goal. There are many health benefits to increasing your fiber intake, including helping with weight loss, improving digestion, and having more energy.

What is the best type of fiber supplement to take?

The best fiber supplement will provide a combination of both soluble and insoluble fiber. Soluble fiber is best for relieving bowel issues like diarrhea and improves elimination. Insoluble fiber will help keep you feeling full, improve digestion and assist with weight loss.

Will fiber help me lose belly fat?

Yes, fiber can help lose belly fat as it will keep you feeling full, which can lower your daily calorie intake. The key to losing fat is to stay in a daily caloric deficit, which is a state where you are burning more calories than you are consuming. It forces the body to rely on stored body fat for energy. 

The Bottom Line

By taking a fiber supplement, you will ensure that you are meeting your daily fiber requirement. As a result, you will more easily be able to lose weight, your digestion and elimination will improve, your skin glow, and you will have more energy. It’s not bad for a supplement that costs you just a few cents every day.

The best fiber supplement on the market right now is Bellway Super Fruit + Fiber. It provides five grams of fiber per serving.
