Fibre supplements stocked in Ireland and dispatched next-day from our Dublin base. Inulin, psyllium husk, partially hydrolysed guar gum (PHGG) and prebiotic fibre, as powders and capsules.
Dietary fibre is a group of carbohydrates that the body does not fully digest. It is found naturally in wholegrains, fruit, vegetables, pulses, nuts and seeds. Fibre supplements provide a specific type of fibre in a measured amount, in a powder, capsule or sachet, for people who prefer to add a known quantity of a single fibre to their day.
How much fibre do adults need? The European Food Safety Authority (EFSA) sets the adequate intake for adults at 25 g of fibre per day. Dietary fibre comes from food first; a supplement adds a measured amount of one specific fibre on top of the diet.
Not sure which fibre is right for you? Our guide to fibre supplements in Ireland explains the 25 g/day target, soluble versus insoluble fibre, how inulin, psyllium and PHGG differ, and how to start without discomfort.
Types of fibre supplement
-
Inulin. A soluble prebiotic fibre, usually extracted from chicory root. Sold as an unflavoured powder.
-
Psyllium husk. A soluble, gel-forming fibre from the seed husk of Plantago ovata. Sold as capsules or powder.
-
Partially hydrolysed guar gum (PHGG). A soluble prebiotic fibre, often sold under the Sunfiber name. A low-viscosity powder that dissolves clear.
-
Resistant maltodextrin. A soluble, digestion-resistant fibre (for example Fibersol). A neutral-tasting powder.
-
Probiotic plus prebiotic fibre. Combination products that pair live cultures with a prebiotic fibre in one capsule.
Soluble and insoluble fibre
Fibre is broadly split into two types. Soluble fibre dissolves in water and forms a gel; inulin, psyllium, PHGG and resistant maltodextrin are all soluble fibres. Insoluble fibre does not dissolve and adds bulk; it is found mainly in wholegrains, bran and vegetables. Most fibre supplement powders sold here are soluble fibres. A varied diet provides both types.
Some specific fibres carry authorised EU health claims at defined daily amounts. Where that applies to a product, it is stated on that product's own page, not here.
Frequently Asked Questions
What is a fibre supplement?
A fibre supplement provides a specific type of dietary fibre in a measured amount, as a powder, capsule or sachet. Common forms include inulin, psyllium husk, partially hydrolysed guar gum and resistant maltodextrin. They are food supplements, not medicines.
How much fibre do adults need per day?
The European Food Safety Authority (EFSA) sets the adequate intake for adults at 25 g of fibre per day. Most of this should come from food. A supplement adds a measured amount of one specific fibre on top of a varied diet.
What is the difference between soluble and insoluble fibre?
Soluble fibre dissolves in water and forms a gel; inulin, psyllium, PHGG and resistant maltodextrin are soluble fibres. Insoluble fibre does not dissolve and adds bulk, and is found mainly in wholegrains and vegetables. A balanced diet includes both.
What types of fibre supplement do you stock?
Inulin (chicory), psyllium husk (Plantago ovata), partially hydrolysed guar gum (PHGG, sold as Sunfiber), resistant maltodextrin (Fibersol), and combination products that pair a prebiotic fibre with live cultures. Each product page lists the fibre type and the amount per serving.
Are fibre supplements suitable for vegans?
Most fibre powders are plant-derived and suitable for vegans. Capsule products depend on the capsule shell, which may be vegetarian hypromellose or gelatine. Check the capsule type and ingredients on the individual product page.
Can I take a fibre supplement every day?
Fibre is a normal part of the daily diet. If you are adding a supplement, it is sensible to start with a smaller amount, take it with plenty of water, and build up gradually. Follow the directions on the product label. If you are pregnant, taking medication or under medical care, check with your GP or pharmacist first.
