The best fibre supplements 2026 – tried and tested

If fibre isn’t something you actively think about, you’re not alone. Most adults in the UK fall well short of the recommended 30g per day, despite its importance. Found naturally in wholegrains, fruit, vegetables, beans and pulses, fibre plays a key role in digestion, helping to keep bowel movements regular and support overall gut health.

Different types of fibre work in different ways. Soluble fibre absorbs water to form a gel-like substance that can help soften stools, regulate blood sugar and support cholesterol levels, while insoluble fibre adds bulk and helps food move through the digestive system. Some fibres are also fermentable, acting as prebiotics that feed beneficial gut bacteria.

While it’s best to get fibre from whole foods, supplements can be useful when diet alone isn’t enough. Fibre supplements are available in powders, capsules and tablets, with psyllium husk and glucomannan among the most commonly used. A gradual increase is recommended, along with plenty of fluids, to minimise digestive discomfort.

Safe, affordable and widely available, fibre supplements can help bridge the gap between what we eat and what our bodies need. Whether you’re aiming to improve regularity, support gut health or manage appetite, they can be a practical addition to a balanced diet. Read on to discover the best fibre supplements, tailored to meet a variety of health and lifestyle needs.

How we tested fibre supplements

To put together our edit of the best fibre supplements, we combined expert advice with hands-on testing. Nutritionist Kerry Torrens helped guide the process, sharing her insight into how different types of fibre work in the body, which forms are most effective for digestive health, and what to look for in terms of safe and tolerable dosing.

All supplements were tested in the same way: we only reviewed fibre capsules, rather than powders or gummies. Each capsule was taken according to the manufacturer’s instructions, and observations were recorded using our in-depth testing criteria.

The Good Food team included samples from a variety of brands, covering different price points and formulations to suit different budgets. The key areas we assessed were:

• Ease of use: how easy are the capsules to take and incorporate into a daily routine?
• Fibre content: how much fibre is provided per daily dose, and how does this contribute towards recommended daily intake?
• Additives: does the product contain unnecessary additives such as preservatives, artificial sweeteners or colourings?
• Dietary requirements: does the product meet specific dietary needs, for example, is it suitable for vegetarians or vegans?
• Value for money: how does it compare to similar products on a cost-per-day basis?

Best fibre supplements to buy in 2026

Zipvit Psyllium Husk 1400mg

Available from Zipvit (£11.99)

Best high-strength option

Star rating: 5/5

If you want a simple, high-potency product, Zipvit is a must for your supplement stack. These capsules are soluble, gel-forming fibre for regularity and fullness. They are easy to swallow, neutral in taste and deliver a good amount of fibre without the need for powders or mixing. The price feels fair for the quantity provided, and the bottle size suits regular use. There are no added extras here, but that simplicity will appeal if you’re looking for something straightforward and effective rather than a more complex blend.

Available from:

• Zipvit (£11.99)

New Leaf Psyllium Husk Fibre with Acidophilus Capsules

Available from New Leaf Products (£14.95)

Best psyllium and probiotic combo

Star rating: 5/5

These capsules are small, neutral in taste and easy to take, making them simple to use every day. New Leaf's offering is a soluble, gel-forming fibre that supports bowel and gut bacteria. The addition of friendly bacteria provides an extra layer of help without complicating the formula. I noticed that the bottle provides a generous number of servings for the price, and the clear instructions make taking these capsules easy. Overall, New Leaf's product is an effective option that delivers more than basic fibre alone.

Available from:

• New Leaf Products (£14.95)

Cytoplan Psyllium Husk Capsules

Available from Cytoplan (£20.64)

Best clean capsules

Star rating: 5/5

I've been using Cytoplan products for years as I really rate the brand for its simplicity and consistency. These are a soluble, gel-forming fibre to help with digestion and stool regulation. They’re completely tasteless, easy to swallow and fit into a daily routine. Each serving delivers a decent amount of fibre without any unnecessary ingredients, making them a strong choice for regular use. The packaging feels sturdy and is clearly labelled, so everything about this product feels carefully considered. While they’re more expensive than some alternatives, I find that the quality and ease of use make them feel worth the investment.

Available from:

• Cytoplan (£20.64)

NOW Foods Psyllium Husk Caps

Available from iHerb (£9.89)

Best budget option

Star rating: 4.5/5

NOW Foods is another brand I have been using for years, and their soluble, gel-forming fibre capsules impress me for their value. Despite the low price, they deliver reliable ingredients and are suitable for long-term use. The capsules are slightly larger than some others, but still easy enough to swallow with water. There’s no taste or unpleasant texture, and the large bottle size means fewer repeat purchases. While the packaging is basic, the product itself performs reliably and offers excellent value compared with higher-priced options.

Available from:

• iHerb (£9.89)

Dr Vegan Fibre Complex

Available from Dr Vegan (£39.99)

Best premium fibre blend

Star rating: 4.5/5

I've always found that Dr Vegan capsules are easy to swallow and the packaging is handy for travelling with. The Fibre Complex capsules are made with mixed plant fibres that can support with digestion and satiety. It’s more expensive than some of the others listed, but if you’re looking for something more advanced and are happy to pay more, this is a strong contender. The formulation is carefully designed and the on-pack information is clear. Dr Vegan, as the name suggests, is also the perfect choice for anyone following a plant-based diet, and is regularly used by my vegan professional athlete friends.

• Dr Vegan (£39.99)

Kiki Health Organic Psyllium Husks

Available from Kiki Health (£22)

Best organic fibre

Star rating: 4/5

Kiki Health's offering is a super-clean and premium soluble, gel-forming fibre for bowel and gentle digestion support. The brand sources its organic psyllium husks from plantago seeds grown without pesticides or herbicides on sustainable farms. So these capsules prioritise convenience and purity, which makes them easy to use every day with very little effort. They’re completely tasteless when swallowed and the tub is compact, so stores well. A little bit more pricy, but I rate them as a solid option if you want a reliable, organic psyllium product.

Available from:

• Kiki Health (£22)

Roundway Supplements Akkermansia and Inulin Capsules

Available from Healf (£12.59)

Best synbiotic for gut support

Star rating: 4/5

These soluble, fermentable fibre capsules are designed to feed beneficial gut bacteria. So if you are looking for a product that leans more on gut balance than fibre alone, Roundway is a smart option. They’re small, tasteless and easy to take, making them simple to include in a routine. The price feels reasonable for what’s included, although the fibre content is lower than some other options in this list. This makes them better suited to general gut support rather than significantly increasing fibre intake, but they’re still a useful addition for the right person.

Available from:

• Healf (£12.59)

Terranova Microflora Complex

Available from Bodykind (£25.69)

Best probiotic blend

Star rating: 4/5

As a prebiotic fibre blend that supports gut microbial balance, Terranova leans more towards digestive balance than fibre intake. The capsules are easy to swallow and clearly labelled, but the price is high compared with simpler fibre products. It’s best viewed as a specialist option rather than an everyday fibre supplement. If gut comfort is your main concern, it may be worth considering, but it’s less cost-effective if fibre is your primary goal.

Available from:

• Bodykind (£25.69)

Higher Nature ColoClear Extra

Available from Higher Nature (£24.18)

Best advanced colon support

Star rating: 4/5

Higher Nature's offering is a quality blend of ground flax seeds, aloe vera, probiotic and digestive herbs fenugreek and fennel. Its mixed fibre and herbs make this a good option if you are looking to support normal bowel movement, help with bloat and ease discomfort. I'd say this is an ideal daily support for feeling lighter. The capsules are easy to take and the instructions are clear, but the price reflects the supplement's more specialist positioning. It may suit those dealing with ongoing digestive discomfort, though it feels less necessary if you’re simply looking to increase daily fibre intake.

Available from:

• Higher Nature (£24.18)

GP Nutrition Fibre Capsules

Available from GP Nutrition (£16)

Best for simple ingredients

Star rating: 4/5

A soluble, gel-forming fibre designed for regularity and simple fibre support, GP Nutrition's capsules offer a straightforward approach with no added extras. They’re easy to swallow, and simple to store as they are in a packet rather than a bottle, making them easy to use every day and travel with. The price sits comfortably in the middle of the range, and the packet lasts a reasonable length of time. I would recommend GP Nutrition if you want something uncomplicated that does the job without paying for premium blends.

Available from:

• GP Nutrition (£16)

Colon Broom Colon Cleanse Capsules

Available from Colon Broom (£24.99)

Best for feeling lighter

Star rating: 3.5/5

Colon Broom's formula includes psyllium husk, probiotics (5 billion CFU), senna leaf extract, aloe vera leaf extract, magnesium citrate and ginger root extract. It is a soluble, gel-forming plus laxative fibre for quick bowel relief; a combination designed to support digestion and help you feel lighter.

While this isn’t the simplest fibre blend on the market, each ingredient serves a clear purpose, particularly when it comes to easing bloating and promoting regularity. I did notice it worked fairly quickly, which makes it appealing if you’re looking for short-term relief.

However, the price is noticeably higher than many similar products that deliver comparable results. For me, it does what it claims in terms of quick relief and digestion support, but it is pricier.

Available from:

• Colon Broom (£24.99)

Protein Works Hunger Killa

Available from The Protein Works (£9.99)

Best appetite-support fibre

Star rating: 3.5/5

Hunger Killa is a less-concentrated fibre product containing soluble, gel-forming glucomannan, along with ginger extract, chromium, and inositol. Protein Works’ formula is more focused on supporting feelings of fullness than on providing a large amount of fibre.

While the capsules are easy to swallow and convenient, and the fibre content is relatively modest. It may be useful as part of a diet plan, but it is not intended as a primary fibre supplement. Think of this as a supporting product rather than a core fibre option.

Available from:

• The Protein Works (£9.99)

Why do we need fibre supplements?

According to nutritionist Kerry Torrens, we don’t actually need fibre supplements. However, when dietary fibre intake consistently falls below the recommended 30g per day for adults, supplements may be useful as a top-up. They can help manage certain issues such as constipation, high cholesterol, appetite regulation and weight control.

It’s important to distinguish between fibre from whole foods and fibre supplements. Whole foods naturally contain different types of intrinsic fibre from plant sources such as legumes, wholegrains, fruit and vegetables. Fibre supplements, by contrast, are typically isolated or extracted fibres.

There are many ways to increase fibre intake without supplements, including swapping refined grains for wholegrains, adding ground flaxseed to porridge or smoothies, and including more beans and pulses in meals. Most evidence linking fibre to health benefits is based on diets rich in a wide variety of fibrous whole foods, while there is less clinical evidence for fibre supplements alone.

Anyone considering a fibre supplement should speak to their GP if they have a diagnosed digestive condition such as diverticulitis, inflammatory bowel disease or Crohn’s disease, or if they are taking prescription medication.

What is the difference between soluble and insoluble fibre?

Soluble fibre dissolves in water and may become viscous or gel-like. This makes it gentler on the digestive system and helps slow digestion, which can support blood sugar control and cholesterol management.

Insoluble fibre is often referred to as ‘roughage’ – it adds bulk to stools, supports regular bowel movements and helps prevent constipation.

When considering supplements, this distinction needs to go further. Fibres are also categorised by whether they are fermentable by gut bacteria and whether they form a gel. These properties determine how a fibre behaves in the body and which benefits it offers.

Some fibres primarily act as laxatives, others feed beneficial gut bacteria (prebiotics), while gel-forming fibres slow nutrient absorption and promote fullness. Not all fibre works in the same way – for example, only viscous, gel-forming soluble fibres have been shown to support blood sugar management.

What are the different types of fibre supplements?

Fibre supplements generally fall into one of four categories based on their properties: whether they are soluble or insoluble, fermentable or non-fermentable, and whether they form a gel.

These characteristics determine what the supplement is best suited for, such as relieving constipation, supporting gut health, managing cholesterol or helping regulate appetite. Highlighting these differences is important, as not all fibre supplements deliver the same outcomes.

Supplements are available in several formats, including powders, syrups, capsules, tablets and gummies. While the format may affect convenience or tolerance, the fibre’s properties are what ultimately determine its effect.

When should you take fibre supplements?

Fibre supplements should generally be taken away from prescription medications and other supplements, as high fibre intakes can interfere with absorption. Products designed to support bowel regularity are often recommended in the evening or before bedtime, but guidance can vary depending on the product.

It’s important to follow label instructions and introduce fibre gradually to minimise digestive discomfort.

Fibre supplements vs probiotic supplements

Fibre supplements provide non-digestible carbohydrates that support digestion and, in some cases, act as prebiotics – a food source for beneficial gut bacteria. This can help improve gut diversity and overall digestive health.

Probiotic supplements, on the other hand, contain live bacteria intended to support or rebalance the gut microbiome. While prebiotics and probiotics work well together, they serve different functions.

You may also see the term synbiotic, which refers to supplements that contain both prebiotic fibre and probiotic bacteria.

What happens if we don’t consume enough fibre?

Consistently low fibre intake can have both short- and long-term health implications. Over time, it may increase the risk of digestive conditions such as diverticular disease and potentially bowel cancer. Other effects include blood sugar fluctuations, increased hunger after meals, difficulties with weight management, poorly controlled cholesterol and hormonal imbalance.

Many of the well-established health benefits of fibre come from diets rich in fibrous whole foods. Much of this evidence predates the widespread use of synthetic and extracted fibres, reinforcing the importance of prioritising fibre from a balanced, varied diet wherever possible.

If you are unsure about how much fibre you are consuming, it is worth using a tracking app like Nutracheck to make sure that you are getting enough from food sources.
