| 5 Best Fiber Supplements for Hemorrhoid Relief |
Last Updated: June 2026 | Medically Reviewed | Based on Clinical Research
Hemorrhoids are more common than most people think. In fact, nearly half of all adults will deal with them at some point in their lives.
They can cause itching, burning, bleeding, and real pain — and they have a way of making even the most ordinary daily tasks feel unbearable.
One of the most effective ways to find relief is also one of the simplest: eating more fiber.
Fiber helps soften your stools and makes them easier to pass.
When you strain less during bowel movements, there is less pressure on the veins in and around your rectum — and that is exactly what hemorrhoids need to calm down and heal.
Research has shown that fiber supplementation can cut the risk of hemorrhoid bleeding by as much as 50%.
That is a big number for something you can buy off a shelf.
If you struggle to get enough fiber from food alone, a supplement can make a real difference.
This article walks you through the five best fiber supplements available on Amazon — all well-reviewed, easy to find, and backed by science.
Why Fiber Helps With Hemorrhoids
Hemorrhoids form when the veins in and around your rectum come under too much pressure.
One of the most common reasons for that pressure is constipation — specifically, the straining that comes with trying to pass hard, dry stools.
Fiber works in two main ways.
- Soluble fiber absorbs water and forms a soft, gel-like substance in your gut, which makes stools softer and easier to move through your body.
- Insoluble fiber adds bulk to your stool, which helps it move more quickly through your digestive system.
Most adults need around 25 to 38 grams of fiber per day, but the average person gets only about half that.
A fiber supplement fills in that gap. Just remember:
You always need to drink plenty of water — at least 8 cups a day — when taking fiber.
Without enough water, fiber can actually make constipation worse.
The 5 Best Fiber Supplements for Hemorrhoids on Amazon
1. Metamucil Psyllium Husk Powder
Best Overall Pick
Metamucil is the most well-known fiber supplement on the market, and for good reason.
It is made from psyllium husk, a natural plant-based fiber that is widely recommended by doctors for hemorrhoid relief.
Psyllium is unique because it contains both soluble and insoluble fiber — about 70% soluble and 30% insoluble — which means it softens stools while also adding bulk, giving you the best of both worlds.
Metamucil has tens of thousands of reviews on Amazon and holds strong ratings across its powder and capsule forms.
Users regularly report softer stools, fewer straining episodes, and noticeable improvement in hemorrhoid symptoms within a few days of consistent use.
It comes in flavored powder (mix with water), unflavored powder, and capsule form, so you can choose what works best for you.
How to use it: Mix one serving in a full glass of water (at least 8 oz) and drink it right away.
Start with one serving per day and work up to more if needed.
Always follow with extra water throughout the day.
Things to keep in mind: Some people experience mild gas or bloating at first, especially if they jump to a high dose too quickly. Start low and go slow.
Metamucil 4-in-1 Psyllium Fiber Supplement
114 servings · 23.3 oz · Unflavored powder · No added sweeteners · Digestive health · Heart health · Blood sugar support
⭐ America's #1 fiber brand · 114 teaspoon servings
Metamucil is America's #1 fiber brand — and this unflavored psyllium powder does more than prevent constipation. Its 4-in-1 formula supports digestive health, appetite control, heart health by lowering cholesterol, and healthy blood sugar levels. For hemorrhoid sufferers, the daily fiber keeps stools soft and regular, drastically reducing the straining that causes and worsens flare-ups. 114 servings per canister with no added sweeteners.

2. Benefiber Prebiotic Fiber Supplement
Best for Sensitive Stomachs
If Metamucil causes you too much gas or bloating, Benefiber is often the next recommendation from doctors.
It is made from wheat dextrin, a type of soluble fiber that is gentle, fully dissolves in water, and is completely tasteless and clear.
You can stir it into water, coffee, juice, or even soup — and you will never know it is there.
Benefiber does not form a thick gel the way psyllium does, which makes it much less likely to cause the gassy feeling that some people get from other supplements.
It also works as a prebiotic, meaning it helps feed the good bacteria in your gut, which can improve your overall digestive health over time.
It has thousands of strong reviews on Amazon, with many users praising how easy it is to take consistently without any discomfort.
How to use it: Stir 2 teaspoons into 8 oz of any non-carbonated drink up to three times per day. Do not mix with carbonated drinks.
Things to keep in mind: Benefiber is not gluten-free (it is wheat-based), so it is not suitable for people with celiac disease or gluten intolerance.
Benefiber Prebiotic Fiber Supplement Powder
250 teaspoons · 17.6 oz (500g) · Sugar-free · Taste-free · Plant-based fiber · Nourishes good bacteria
⭐ Highly rated on Amazon · Haleon trusted brand
Benefiber goes beyond basic fiber — it's a prebiotic fiber that not only softens stools to reduce straining, but also nourishes the good bacteria in your gut for better long-term digestive health. Completely taste-free and sugar-free, it dissolves clear in any liquid without changing the texture or flavor. 250 servings per canister makes it one of the longest-lasting fiber supplements available. A great daily habit for preventing hemorrhoid flare-ups.

3. Citrucel Methylcellulose Fiber Caplets
Best for Minimal Gas and Bloating
Citrucel is made from methylcellulose, a type of synthetic soluble fiber that does something most fiber supplements do not: it does not ferment in your gut.
Fermentation is what causes gas and bloating with some fiber products. Because methylcellulose skips that process entirely, Citrucel is often considered the most gentle option on this list.
This makes it a great choice for people who have tried other supplements and found them too uncomfortable.
It is also very easy to take — just swallow the caplets with water. No mixing, no powder, no taste to deal with.
Citrucel has a loyal customer base on Amazon and consistently earns strong reviews from people who could not tolerate other fiber supplements but found relief with this one.
How to use it: Take 2 caplets with at least 8 oz of water up to 6 times per day. Always drink extra water throughout the day.
Things to keep in mind: The caplets are fairly large. If you have difficulty swallowing pills, Citrucel also comes in an orange-flavored powder.
Citrucel Methylcellulose Fiber Therapy Caplets
100 fiber caplets · Methylcellulose fiber · No excess gas · Clinically proven · Easy flip top cap
⭐ Highly rated on Amazon · Clinically proven effective
Citrucel uses methylcellulose fiber — a non-fermentable fiber that won't cause the excess gas and bloating that some people experience with psyllium-based products. Clinically proven gentle and effective for relieving occasional constipation and irregularity. For hemorrhoid sufferers who need reliable daily fiber but have a sensitive digestive system, Citrucel is often the smarter choice.

4. NOW Supplements Psyllium Husk Powder
Best Budget-Friendly Option
NOW Supplements is a trusted name in the health world, known for making clean, affordable, no-frills supplements. Their psyllium husk powder delivers the same core fiber — the same type found in Metamucil — at a noticeably lower price per serving.
If you want the benefits of psyllium without paying a premium brand price, NOW Supplements is an excellent choice. It is pure psyllium husk with no added sugar, no artificial colors, and no unnecessary ingredients. It is also non-GMO and comes in a large container that can last several months.
Many Amazon customers note how well it works for keeping stools soft and reducing the need to strain, with several specifically mentioning improvement in hemorrhoid symptoms.
How to use it: Mix 1 teaspoon in a full glass of water (8–12 oz) and drink quickly before it thickens. Follow immediately with another full glass of water.
Things to keep in mind: Plain psyllium powder has a slightly earthy taste and can thicken quickly in water. Drink it fast and chase it with more water.
NOW Foods Psyllium Husk Powder — 24 oz
24 oz (680g) · Soluble fiber powder · Non-GMO verified · Vegetarian/Vegan · Resealable bag
⭐ Highly rated on Amazon · NOW Foods trusted brand
The best bulk psyllium husk powder option on this list — 24 oz of pure soluble fiber from NOW Foods, one of the most trusted supplement brands in the USA.

5. Garden of Life Raw Organic Fiber
Best for Clean, Whole-Food Ingredients
For people who prefer a more natural, organic approach, Garden of Life Raw Organic Fiber is a top choice. Rather than isolating a single fiber type, this supplement uses a blend of over 15 sprouted seeds, grains, and legumes to deliver both soluble and insoluble fiber in a form that feels closer to eating real food.
It is certified USDA organic, non-GMO, gluten-free, vegan, and free from artificial additives. It also contains digestive enzymes and probiotics, which can help your gut work more comfortably as your body adjusts to more fiber.
This is a great option if you are dealing with hemorrhoids and also want to support your overall gut health at the same time. It has a loyal following on Amazon among health-conscious users.
How to use it: Mix 1 scoop with 8–12 oz of water or your favorite smoothie once daily. Adjust as needed.
Things to keep in mind: This supplement has a stronger earthy flavor than some others. It blends best in a smoothie. It is also a bit pricier than the other options on this list.

Tips for Getting the Most Out of Your Fiber Supplement
Drink plenty of water. This is not optional. Fiber needs water to do its job. Without enough fluid, fiber can actually make constipation worse and may even cause choking in some cases.
Start with a small dose. If you jump straight to a full serving, you may experience gas, bloating, or stomach cramps. Start with half the recommended dose for the first week, then slowly increase.
Be consistent. Fiber supplements are not a one-time fix. They work best when taken every day as part of your routine.
Take them at the right time. Taking fiber supplements at least one hour before or two hours after any medications can help prevent the fiber from interfering with how your body absorbs the medicine.
Combine with other healthy habits. Fiber supplements work best alongside a diet rich in fruits, vegetables, and whole grains, regular physical activity, and avoiding sitting for long periods.
When Fiber Is Not Enough
Fiber supplements work very well for mild hemorrhoids (Grade 1) and can significantly reduce symptoms like bleeding and discomfort. However, if your hemorrhoids are more advanced — Grade 2, 3, or 4 — fiber alone may not be enough to shrink them. In those cases, you may need to talk to a doctor about other treatment options, ranging from minor in-office procedures to minimally invasive treatments.
If you notice persistent rectal bleeding, severe pain, or your symptoms do not improve after a few weeks of increased fiber intake, please see a healthcare provider. Rectal bleeding is always worth checking out.
Conclusion
Hemorrhoids are painful and frustrating, but they do not have to be a permanent part of your life.
Simply adding a fiber supplement to your daily routine — along with drinking more water and eating well — can make a real, measurable difference.
Research backs this up: people who take fiber supplements regularly have a much lower risk of bleeding and other uncomfortable symptoms.
Of the options on this list, Metamucil is the strongest all-around choice for most people. But if your stomach is sensitive, Benefiber or Citrucel may suit you better. And if budget or organic sourcing matters to you, NOW Psyllium Husk or Garden of Life are both solid picks.
The best fiber supplement is the one you will actually take every day. Choose the one that fits your lifestyle, drink your water, and give it a few days. Relief may be closer than you think.
