The Best 11 Fiber Supplements for Women to Support Your Health

Fiber is widely known for its ability to help keep you regular, but it can do even more for your gut health. As fiber moves through your digestive system, it can stabilize your appetite, support a healthy gut microbiome, reduce inflammation, and lower the risk of colorectal cancer. Higher fiber intake may also help lower your risk of heart disease, stroke, type 2 diabetes, and high cholesterol.

Despite these health benefits, more than 90 percent of women don’t meet the recommended intakes for dietary fiber.

 Women need around 22 to 28 grams (g) per day, while men need 28 to 34 g per day. Men and women have different fiber needs because in general, men have more muscle mass than women, which means they need more nutrients and calories. (Fiber requirements for both men and women decrease slightly older than 50.)

While you can get enough fiber through food, some women may need to use a supplement to help them reach their daily fiber goals. To help you choose the best fiber supplement, we rounded up the top 11 fiber supplements for different health and lifestyle needs.

Our Top Picks for Best Fiber Supplements for Women

When to Consult Your Doctor

Everyday Health recommends speaking with your doctor before adding any supplement to your diet to make sure it’s safe and appropriate for your individual health needs. Some supplements can interact with medications, so if you take any prescribed medications, always talk with your doctor first. While fiber supplements are generally well tolerated, sometimes they can lead to temporary gastrointestinal (GI) distress like gas, bloating, cramping, and change in bowel movements. Your doctor can help you understand how the supplement will affect you and whether any symptoms you experience are cause for concern.

Tomorrow's Nutrition SunFiber powder

Best for Sensitive Stomachs

Tomorrow's Nutrition SunFiber

Pros

  • Gentle formula for easy digestion
  • Contains prebiotics to support healthy gut microbiome
  • Low-FODMAP certified, non-GMO
  • Dissolves quickly, doesn’t change the texture of food or drink
  • Unflavored
  • Third-party tested

Cons

  • May be harder to find in store than other fiber supplements

Key Specs

  • Fiber type: Guar gum
  • Fiber per serving: 6 g
  • Form: Powder
  • Serving size: 1 scoop
  • Third-party tested: Yes

If you’re looking for a fiber supplement, chances are you’ve experienced some digestive discomfort. Some fiber supplements may not sit well with people with sensitive stomachs, but Tomorrow’s Nutrition SunFiber was designed to be gentle on your digestive system with a low FODMAP-certified formula. FODMAPs are a group of carbohydrates that can lead to digestive issues in some people, especially those with irritable bowel syndrome (IBS).

SunFiber is a type of fiber that comes from guar beans. It’s different from other guar gum–based fiber supplements because a process called hydrolyzation is used to break down the fiber into smaller pieces. The fiber in SunFiber is known as partially hydrolyzed guar gum (PHGG). Research shows that when consumed regularly, PHGG can improve the stool form for people with constipation and diarrhea, plus increase the amount of healthy gut bacteria.

 It’s worth noting that other brands — including ones on our list — use SunFiber in their fiber products as well.

One of the biggest benefits of this formula is that it doesn’t change the consistency of whatever you mix it into. Some fiber supplements thicken the food or liquid that you add it to, and some may add a gritty texture. SunFiber’s formula dissolves completely, making it easier to swallow and consume regularly.
The prebiotics in SunFiber’s formula ferment slowly to limit gas and bloating, which may be helpful for people with irritable bowel syndrome (IBS) or sensitive stomachs. Prebiotics help feed the healthy bacteria in your gut to support healthy digestion and immune health.

The formula is also gluten-free, dairy-free, and certified organic. Tomorrow’s Nutrition SunFiber supplements are third-party tested by LGC Assure and have Informed Ingredient Certification that confirms the supplements are free of impurities and substances banned in sports nutrition products.

Best for Weight Loss

Viva Naturals Organic Psyllium Husk Powder

$18.49 at Walmart
$16.83Now -10% Off

Pros

  • Helps manage hunger and feeling of fullness
  • Gluten-free, paleo, keto-friendly
  • Mixes well into smoothies, baked goods, or cereals
  • Can be used to thicken drinks or soups
  • Non-GMO, organic

Cons

  • May be less palatable with plain drinks like water
  • Slight earthy flavor

Key Specs

  • Fiber type: Psyllium
  • Fiber per serving: 4 g
  • Form: Powder
  • Serving size: 1 tsp
  • Third-party tested: Yes
When you’re trying to lose weight, consuming fiber can help manage hunger and maintain that feeling of fullness can help you stick with your eating plan. The two types of fiber are soluble and insoluble fiber. Soluble fiber dissolves in water and often can be fermented by gut bacteria to form short-chain fatty acids that support healthy gut bacteria. Insoluble fibers are usually found in the outer skin of plant foods. They’re not digested, so they help bulk up stool and promote regular bowel movements.

Psyllium is a type of soluble fiber that absorbs water to form a gel that can help slow digestion, which could help you feel full longer. Research suggests psyllium could also help with managing blood sugar and cholesterol levels.

Viva Naturals Organic Psyllium Husk Powder is a good option for mixing into your food or drinks to support weight management. It’s friendly to different diet types, including paleo, keto, gluten-free, and vegan diets. Viva Natural’s powder is milled to create a smooth texture that’s easy to mix into smoothies, oatmeal, or baked goods. Pairing it with carbs may help prevent spikes in energy from blood sugar changes because of psyllium's effects on digestion.

It’s worth noting that it thickens whatever liquid you mix it into, so it may not be best with plain liquids where the consistency could be unpleasant or even unsafe for people who have trouble swallowing. On the other hand, the thickening effect could work in smoothies or soups. Viva Natural’s fiber supplements are third-party tested to ensure the quality and purity of ingredients.

Best for Daily Use

NOW Foods Psyllium Husk Powder

$16.55 at Amazon
$22.99Now 28% Off

Pros

  • Well tolerated in daily use and helps meet your daily fiber needs
  • CGMP-certified
  • Participates in packaging recycling program

Cons

  • Could cause digestive discomfort if you're not drinking enough water
  • Harder to mix

Key Specs

  • Fiber type: Psyllium
  • Fiber per serving: 7 g
  • Form: Powder
  • Serving size: 1 tbsp
  • Third-party tested: Yes
“Psyllium husk powder has been found to help with constipation, diarrhea, and other gastrointestinal issues,” says Lindsay Fencl, RD, who practices in Green Bay, Wisconsin. “In addition, it can support stable blood sugar and cholesterol levels.”

 Psyllium husk is a great option for daily use because it supports regularity and stool form for both constipation and diarrhea and offers the other health benefits listed above.
One tablespoon provides 7 g of fiber. “The recommended daily intake for fiber is 25 g for women and 35 g for men,” explains Fencl, “so this psyllium husk powder gets you around one-quarter of the way there with just one tablespoon.”

It’s recommended to vigorously mix 1 tablespoon with 12 ounces (oz) of water and drink immediately. Because soluble fiber absorbs water, it could lead to tolerance issues, such as bloating, gas, and abdominal discomfort, if you’re not drinking enough water. “Drink an extra 20-24 oz of water to ensure that bowel movements are able to sufficiently pass and prevent buildup,” says Fencl. NOW Foods Psyllium Husk Powder is also third-party tested and CGMP-certified.

Best Powder

Thorne FiberMend

$42 at Amazon

Pros

  • Powder dissolves quickly, with smooth consistency
  • Contains prebiotics to support a healthy gut
  • Formulated to limit excess bloating, cramping, gas
  • Unflavored

Cons

  • Priciest on our list
  • Product settles in the container

Key Specs

  • Fiber type: Guar gum, rice bran, pectin
  • Fiber per serving: 7 g
  • Form: Powder
  • Serving size: 1 scoop
  • Third-party tested: Yes
Thorne FiberMend is a prebiotic fiber powder meant to help maintain regularity and support a healthy gut. This formula uses a blend of SunFiber, rice bran, larch arabinogalactan, apple pectin, and green tea phytosome. The unique components work together to support regularity and balanced gut flora. Research suggests rice bran supplements contain phenolics that can support a healthy gut and rice bran to protect against cancer, vascular diseases, and type 2 diabetes.

Larch arabinogalactan is a type of dietary fiber that ferments in the intestine and can help support a healthy gut microbiome and immune health.

Apple pectin is another type of fiber that acts as a prebiotic. Pectin is broken down into short-chain fatty acids (SCFAs) in the digestive tract to support good gut bacteria and immune health.

Green tea contains polyphenols that act as antioxidants and can be used by gut bacteria to support the growth of good bacteria.

 The unflavored blend has a fine, soft texture that dissolves easily, so you can add it to foods or drinks.

Note: The powder can settle and become more compact. It’s suggested to “fluff” the powder or you could get fewer servings per container.

As you may have noticed from this list, it’s more common for fiber supplements to come in powder form. In general, powder fiber supplements tend to provide a higher concentration of fiber per serving than capsules. In addition, powders may be more convenient for people who don’t like swallowing pills.

Metamucil Fiber Gummies

Best Gummy

Best Gummy: Metamucil Fiber Gummies

Pros

  • Easier format for people who don’t like powders
  • Contains prebiotic
  • No added sugars
  • Natural orange flavor

Cons

  • Contains xylitol, a sugar alcohol
  • Orange flavor may not appeal to all
  • 3 gummies per serving

Key Specs

  • Fiber type: Inulin, corn fiber
  • Fiber per serving: 5 g
  • Form: Gummy
  • Serving size: 3 gummies
  • Third-party tested: No
While powders can be an easy way to add fiber to foods or drinks, not everyone likes the consistency of dissolved powders or the taste. Gummies can be a good alternative when you’re looking to add fiber to your diet. Metamucil Fiber Gummies contains a blend of inulin and soluble corn fiber called Fibersol. Fibersol is a type of maltodextrin fiber that helps improve frequency of bowel movement as well as stool volume and consistency.

Not all types of fiber produce the same effects in the body; inulin works differently from the bulk and gel-forming types of fiber. Inulin is a soluble fiber that acts as a prebiotic to support beneficial gut bacteria. It works by stimulating the growth of these good bacteria and offers other health benefits like help to support weight loss, blood sugar levels, and lower inflammation.

There is no added sugar in these gummies, but it does contain a natural sugar alcohol called xylitol. Xylitol is generally well tolerated, but some people may experience digestive discomfort, like gas, bloating, or diarrhea when consuming it. If you have kids at home, be sure to store these gummies out of their reach so that they don’t take more than a recommended serving size.

Best Gluten-Free

Anthony’s Organic Psyllium Husk Powder

$20.99 at Amazon

Pros

  • Batch-tested, verified gluten-free
  • Non-GMO
  • Certified organic, vegan friendly
  • Finely ground powder mixes smoothly

Cons

  • Lower fiber per serving
  • Must drink quickly

Key Specs

  • Fiber type: Psyllium
  • Fiber per serving: 3 g
  • Form: Powder
  • Serving size: 1 tsp
  • Third-party tested: Yes

Anthony’s Organic Psyllium Husk Powder is batch-tested and verified gluten-free. It may help to promote regularity, improve constipation, and support overall digestion. The powder can be mixed with water or smoothies for a boost of fiber. Just note the packaging suggests drinking the supplement right after mixing because it will thicken and form a gel when it’s allowed to sit.

Psyllium husk is naturally gluten free, but sometimes even products that are naturally gluten free could have cross-contamination when processed in facilities that manufacture gluten containing products or have other ingredients with gluten. The only ingredient is psyllium husk, so if you need to avoid gluten, you can be sure this product is safe.

This supplement has a smaller amount of fiber per serving, partially because it’s a smaller serving size of only 1 teaspoon (tsp). This can be a great option for people who experience some digestive discomfort with fiber supplements. If you want more fiber to get closer to the daily recommended fiber intake, it’s easier to take this supplement a couple of times throughout the day to spread your fiber intake throughout the day so it’s not going through your digestive system at one time.

Best for Irritable Bowel Syndrome

Nature’s Nutrition Psyllium Fiber

$9.22 at Walmart
$10.42Now 12% Off

Pros

  • Gentle formula for those with gastrointestinal issues
  • Gluten-free, non-GMO
  • Vegan capsules
  • CGMP certified
  • Third-party tested

Cons

  • Lower in total grams of fiber
  • 3 capsules per serving

Key Specs

  • Fiber type: Psyllium
  • Fiber per serving: 1 g
  • Form: Capsules
  • Serving size: 3 capsules
  • Third-party tested: Yes
Irritable bowel syndrome (IBS) is a gastrointestinal disorder with symptoms like abdominal pain, bloating, gas, constipation, and diarrhea.

 Research suggests that psyllium extracted from the plant P. ovata can help reduce those painful symptoms and normalize bowel movements.

Nature’s Nutrition Psyllium Fiber capsules contain 1,500 milligrams (mg) of psyllium husk powder per serving, which provides about 1 g of dietary fiber. This supplement is also free from sugar, gluten, GMO, and artificial colors or dyes.

If you’re looking for a fiber supplement to help you reach the daily recommended fiber intake, this isn’t the best option, since there’s only 1 g of dietary fiber per serving. But for people with IBS, this low dietary fiber option could be helpful. Some of the dietary fibers that feed healthy gut bacteria ferment, which for people with IBS symptoms can lead to extra gas, bloating, diarrhea, and abdominal discomfort. Psyllium husk is considered a non-fermenting soluble fiber.

Best Budget-Friendly

Benefiber Daily Prebiotic Fiber Supplement

$13.48 at Walmart
$12.94Now -4% Off

Pros

  • Most affordable on our list
  • Unflavored
  • Sugar-free
  • Won’t affect texture when mixed with food or drinks

Cons

  • Not third-party tested
  • Not suitable for people with celiac disease

Key Specs

  • Type of fiber: Wheat dextrin
  • Fiber per serving: 3 g
  • Form: Powder
  • Serving size: 2 tsp
  • Third-party tested: No
The Benefiber Daily Prebiotic Fiber supplements cost less than 25 cents per serving, making it a budget-friendly fiber supplement. It’s made with wheat dextrin, which is a soluble fiber that comes from wheat starch. Unlike psyllium, wheat dextrin doesn’t form a gel or hold onto water. It can be fermented by gut bacteria to support a healthy gut microbiome.

Benefiber supplements dissolve in hot or cold liquids. It’s tasteless, and won’t thicken your drinks like other fiber supplements. While Benefiber is considered “gluten-free” because it contains less than 20 parts per million (ppm) of gluten, it’s still best to check with your doctor if you have a gluten intolerance or celiac disease.

Best for Indigestion

Love Wellness Sparkle Fiber

$12.89 at Walmart
$35.99Now 64% Off

Pros

  • Contains digestive enzymes to break down food
  • Dairy-free, gluten-free, vegan
  • No artificial fragrances, dyes, or flavors
  • Vegetable fiber blend

Cons

  • Lower total fiber per serving
  • Serving size is 3 capsules

Key Specs

  • Fiber type: Psyllium husk, vegetable fiber blend
  • Fiber per serving: 1.5 g
  • Form: Capsules
  • Serving size: 3 capsules
  • Third-party tested: Yes
Indigestion is a general name for a group of digestive symptoms that occur together, such as pain or discomfort, burning sensation, feeling full quickly, and feeling uncomfortably full after eating. It can be caused by lifestyle, medicines, health problems, or digestive diseases, and sometimes it’s idiopathic, meaning the cause is unknown.

One potential factor for frequent indigestion is simply not producing enough digestive enzymes. Your body needs digestive enzymes to break down foods efficiently. Research suggests supplements with digestive enzymes can help to improve symptoms of abdominal discomfort and ingestion.

Love Wellness Sparkle Fiber supplements provide both a fiber blend and digestive enzymes, making this supplement a good option to help support gut health and reduce symptoms of indigestion. This supplement contains both psyllium husk and a powder fiber blend made with broccoli, spinach, celery seed, chia sea, flaxseed, and kale. A blend of different types of fiber can be helpful; it’s a way to get a variety of micronutrients.

The digestive enzyme blend in this supplement includes amylase, bromelain, papain, protease, cellulase, and lipase. Digestive enzymes break down food into smaller molecules, which is necessary for your body to fully digest and absorb the nutrients in food.

 The total serving size is 3 capsules, but the company recommends starting with one capsule because some people experience discomfort if they start with the full recommended serving size daily.
Metamucil 4-in-1 sugar free fiber powder

Best for Constipation

Metamucil 4-in-1 Fiber

Pros

  • More effective than other types of fiber in relieving constipation
  • Orange flavor
  • Sugar-free
  • Mixes well into liquids
  • Gluten-free

Cons

  • Contains artificial flavoring, dyes
  • Contains aspartame
  • Not third-party tested

Constipation can be uncomfortable with its symptoms like infrequent bowel movement (three or fewer per week), hard stools, straining or discomfort when passing stool, abdominal pain, bloating, feeling of fullness, loss of appetite, and hemorrhoids.

 A fiber supplement, especially one with psyllium could help. Metamucil 4-in-1 fiber supplement contains psyllium husk which can help to improve your regularity. Psyllium is 3.4 times more effective at relieving constipation than wheat bran and psyllium fiber doses of at least 10 g per day for at least four weeks can help improve chronic constipation symptoms. Chronic constipation is typically described in studies as three or fewer bowel movements for at least three to six months.

Metamucil 4-in-1 formula is sugar-free; it contains the artificial sweetener aspartame. Some people may not tolerate aspartame and experience symptoms like indigestion, headache, nausea, or insomnia, and high doses of aspartame have been associated with increased cancer risk.

What to Look for in a Fiber Supplement

Types of Fiber

When buying a fiber supplement, it’s helpful to look at the different types of fiber.

Soluble Fiber This type of fiber absorbs water to form a gel-like consistency that softens stool and encourages regularity. It’s found in fruits (such as apples, oranges, strawberries), grains (oats, bran, barley), and vegetables (beans, carrots, sweet potato).

Insoluble Fiber This fiber isn’t digested and moves through your digestive system whole, adding bulk to stool. Food sources of insoluble fiber include fruits (pears, bananas, prunes), vegetables (leafy greens, broccoli), whole grains (brown rice, quinoa), legumes (beans, lentils), and nuts and seeds.

Both types of fiber provide benefits for digestion and health. Insoluble fiber promotes regularity of bowel movements and a healthy digestive tract. This type of fiber can be good for alleviating constipation because it has a laxative effect.

Soluble fibers help slow down digestion which increases feelings of fullness and may decrease appetite. Because soluble fiber absorbs water, it can help improve diarrhea. Soluble fibers also bind and hold to different materials in your digestive tract (such as bile salts). This binding effect limits how much your body can reabsorb which may help manage cholesterol and glucose levels.

Examples of soluble fiber in supplements include psyllium husk, wheat dextrin, and inulin while insoluble fiber includes cellulose and lignin. But often foods and supplements with fiber will contain some of both types of fiber, for example, psyllium husk does contain a little bit of insoluble fiber.

Health Goal

When selecting a fiber supplement, you also want to consider what you’re trying to achieve by taking the supplement. If you find it challenging to reach the recommended daily fiber intake, you’ll probably want to consider one of the fiber supplements with more grams of fiber per serving.

But if you’re looking because of a specific health issue, you’ll want to pick up a fiber supplement created for that concern. That could be helping with blood sugar, cholesterol levels, or digestive concerns like constipation, diarrhea, or indigestion.

Third-Party Testing

Nutrition supplements are not regulated by the U.S. Food and Drug Administration (FDA), but supplement companies can choose to have their products third-party tested to verify ingredient quality and purity. It’s generally recommended to try to pick supplements that have been third-party tested. Some products also undergo other certifications like the Certified Gluten Free, Non-GMO, or Vegan.

FAQs

How much fiber do I need in a day?
The U.S. Department of Agriculture’s (USDA) Dietary Guidelines for Americans recommends the following amounts of daily fiber, depending on age and gender. Women (age 50 and below) need 25–28 g per day, while men (age 50 and below) require 31 to 34 g per day. Women (age 50 and older) should aim for 22 g daily, while men (age 51 and older) should consume around 28 g daily.
Both soluble and insoluble fiber provide health benefits. Insoluble fiber helps with regular bowel movements. Soluble fibers help absorb water to form a gel-like texture and may help with blood sugar and cholesterol management.
Consuming fiber supplements may lead to side effects like bloating and gas, so it’s recommended to take them with plenty of water and drink 6–8 glasses of water throughout the day to prevent constipation.
