Fiber Supplement Buying Guide

Fiber: the unsung hero of your health. So, why is fiber making waves in the health and wellness community? The answer lies in its ability to support not just your digestive system but also your body's fundamental vitality. By incorporating fiber into your daily health routine, you’re taking a proactive step towards ensuring a more balanced and vibrant approach to your health.

Despite its vital role, the average American’s fiber intake often falls short of the recommended daily amount, leaving many vulnerable to common health issues, such as digestive discomfort and irregularity. That’s why the ShopOwl research team put together this quick guide to help you pick a quality fiber supplement. With our expert insights, you can confidently navigate the world of fiber and make an informed choice that will contribute to your overall vitality and well-being.

How Does Fiber Work?

Understanding the inner workings of fiber is the first step toward harnessing its remarkable benefits. Fiber comes in two forms: soluble and insoluble. 

Soluble fiber pulls in water, forming a gel-like substance that aids in regulating blood sugar levels and maintaining healthy cholesterol levels that are already within normal range.* This is what also slows down the emptying of your stomach contents into your small intestine, which plays a role in supporting satiety, the feeling of fullness that keeps you feeling satisfied after eating. Examples include oatmeal, beans, psyllium husk, and the inside of apples.

Insoluble fiber adds bulk to the stool and promotes regular bowel movements, contributing to digestive health. This type of fiber can be found in the outside layers of fruit. Both types are equally important for the body's optimal function and vitality. Examples include wheat bran, leafy greens, grape skins, apple skins, and nuts.

The main food sources of fiber include fruits, vegetables, whole grains, legumes, and nuts. While these food sources certainly provide a wealth of fiber, you may find it challenging to consistently meet your daily fiber needs through diet alone. This is where fiber supplements play a crucial role. By supplementing your diet with a high-quality fiber supplement, you can conveniently bridge the gap between your fiber intake and the recommended daily amount, supporting not only your digestive health but also your overall health.

As you embark on the journey of selecting the best fiber for your needs, keep in mind that not all fiber supplements are created equal. There are a few crucial factors to consider, which we will delve into in the next section of this guide. 

Ingredients to Look for & Avoid in a Fiber Supplement

  • Look For
  • A Variety of Fiber Sources:


    Soluble Fiber for Satiety & Blood Sugar:
    Psyllium husk, beta-glucan (oats, barley), pectin (fruits)
    Insoluble Fiber for Regularity: Wheat bran, flaxseed
    Prebiotic Fiber for Gut Health: Inulin (chicory root), oligofructose, organic acacia gum

  • Minimally processed fiber supplements might offer more natural, beneficial fiber. However, safety and effectiveness are key. Choose a fiber source that suits your needs and prioritize a brand with a good reputation.
  • Prebiotics fuel the good bacteria, which can help ferment the fiber more effectively, potentially enhancing the overall digestive benefits.
  • Avoid
  • Skip the sugar and artificial sweeteners in fiber supplements! They add calories and might disrupt your gut health. Focus on getting your fiber with minimal extras.
  • Artificial colors and flavors could contain food allergies or hide sugar. Choose natural options to focus on the fiber itself.
  • Excessive Fillers and Binders

Avoid Unnecessary Fillers and Binders

You want to ensure you are receiving the purest and most effective product. Fillers are often used in supplements for various reasons, and while they do not provide any nutritional benefits, many people prefer to avoid unnecessary fillers and binders in their fiber supplements for a couple of reasons:

Reduced Concentration of Active Ingredient: Fillers and binders can dilute the amount of actual fiber you consume per serving. If you're taking a fiber supplement to address a specific need, like constipation or digestive health, a higher concentration of fiber might be more effective.

Potential Digestive Issues: Some people might have sensitivities to certain fillers and binders, like wheat or soy, which can cause bloating, gas, or other digestive discomfort.

What Else to Consider Before Purchasing a Fiber Supplement

Specific Fiber Types

Check the ingredient list and prioritize fiber sources like psyllium husk, wheat bran, or inulin over bulking agents like starch or maltodextrin.

Look into specific fiber types that align with your goals. You also want to consider the form (powders, capsules, gummies, wafers) that best suits your preference for ease of consumption.

Positive and Authentic Reviews 

Make sure to check with the ShopOwl algorithm before purchasing a product, so you can get a clear understanding of what other customers liked and didn't like about it. This will help you make a more informed purchase.

Check the Dosages

Look for brands that advertise high fiber content per serving (usually grams of fiber). It’s always a good idea to start with a low dose and gradually increase it as tolerated. This helps minimize potential side effects like gas, bloating, and cramps.
