The 6 Best Fiber Supplements for Healthy Digestion
Fiber is an essential carbohydrate that helps out bodies regulate sugars, hunger and digestion. Fiber is important, but it’s estimated that only 5% of people consume the recommended amount of fiber daily.
Fiber supplements meet your nutritional needs while regulating digestion, preventing constipation and managing glucose and cholesterol levels. There are two types of fiber in supplements — soluble and insoluble fiber. Soluble fiber dissolves in water and helps lower blood sugar and cholesterol levels. Insoluble fiber is the type that helps move food through your digestive system.
If you’ve been looking for a fiber supplement, you’ve come to the right place. Here are our picks for the top six fiber supplements that will keep your gut happy.

How we chose the best fiber supplements
When choosing the best fiber supplements for this list, we considered the price, type of fiber supplement and ingredients. Additionally, as the supplement industry isn’t well regulated by the FDA, we relied on additional certifications that vouch for the quality and purity of products. We did not test these fiber supplements in-house.
Things to consider when buying fiber supplements
There are a lot of fiber supplements on the market, all varying by price, type and form. When you start your search, keep these key factors in mind:
- Type of fiber: There are two types of fiber — soluble and insoluble. Soluble fiber benefits your cholesterol and blood sugar. In comparison, insoluble fiber is what will help with constipation and regular digestion.
- Dosage: According to Mayo Clinic, women should aim for 21 to 25 grams of fiber daily, while men should eat 30 to 38 grams. If you’re not getting enough fiber, you may consider a supplement. You should start with lower fiber content and slowly increase it over time. This way, you avoid side effects like bloating or excess gas.
- What’s in the supplement: Some fiber supplements may include additional sweeteners or gluten. While others may include other vitamins and minerals. Always keep your dietary preferences and limitations in mind.
- Form: Fiber supplements come in several forms, the most common being powder or gummy. Whole food fiber sources are also available, like chia seeds. Note that chia seeds won’t dissolve like a powder, and they also have a taste.
Fiber is an essential carbohydrate that our bodies use to manage the body’s sugars, hunger and digestion. Our bodies can’t break down fiber, so it passes through our digestive systems undigested. This adds weight and softens stool, making it easier to pass.
- Berries, pears, apples
- Brussel sprouts and broccoli
- Chia seeds
- Carrots and beets
Despite fiber being present in so many foods, many people don’t get enough of it from their diet. That’s where fiber supplements come in.
How often should you take fiber supplements?
Fiber supplements are generally considered safe for everyday use. But you should only take them if you’re not getting enough fiber from your food.
There are side effects to fiber supplements that shouldn’t be ignored, however. Your fiber supplement can cause constipation if you take too much too quickly or if you aren’t drinking enough water. When you start your fiber supplements, it’s best to start slowly and at a lower dose, then work your way up.
