Shop Fibre Supplements at Myprotein
Fibre supplements are one of the most practical additions to any daily routine — and one of the most overlooked. Whether you're not hitting your fibre targets through food alone or simply want a more convenient way to top up your intake, this range covers everything from prebiotic powders and soluble fibre supplements to high-fibre gummies, oats, and gut-focused capsules. Whatever format fits your lifestyle, there's a straightforward option here.
Every product in this range is developed by Myprotein's expert nutritionists, with a focus on clean, effective formulations. Chicory inulin, oat beta-glucan, and other established fibre sources sit at the core of the range — each chosen for their nutritional profile and versatility. If you've been looking for the best fibre supplements to complement a balanced diet, this is a solid place to start.
Who Fibre Supplements Are For
Most people in the UK fall short of the recommended 30g of fibre per day. These products are built for anyone who wants to close that gap without overhauling their diet — whether you're a committed gym-goer, someone eating on the go, or simply someone who knows their diet could do with a bit more balance. Fibre isn't just a concern for one type of person; it's a universal nutritional need.
Athletes and active individuals will find options that sit naturally alongside a performance-focused diet — oats and flapjacks that bring fibre alongside protein and carbohydrates, or a prebiotic powder that mixes into an existing shake. If you're newer to fibre supplementation, gummies and capsules offer a low-barrier entry point that doesn't require any recipe adjustments at all.
When to Use Fibre Supplements
Timing is flexible with most fibre supplements, but consistency matters more than the clock. Many people find it easiest to take a fibre powder or capsule at the same point each day — with breakfast, alongside a meal, or mixed into a post-workout shake. Prebiotic options like chicory inulin powder work well stirred into coffee, yoghurt, or smoothies with minimal impact on taste or texture.
Food-based fibre sources like oats and flapjacks slot naturally into mealtimes — pre-training for slow-release carbohydrates, or as a snack to round out the day. Gummies are easy to take at any time and need no preparation at all. The key is finding a format and time that you'll actually stick to.

Chicory inulin is a naturally sourced prebiotic fibre that contributes to normal bowel function by increasing stool frequency1. It's found across several products in this range — including dedicated inulin powder and high-fibre gummies — making it easy to incorporate at a level that works for you.
Multiple Formats for Every Routine
From powders and capsules to gummies, oats, and flapjacks, this range covers a broad spectrum of formats. That variety makes it straightforward to find a fibre supplement that fits around your existing habits rather than requiring you to build new ones.

FAQs
Why do I need fibre?
Fibre is an essential part of a balanced diet, yet most adults in the UK don't consume enough of it. Unlike other carbohydrates, fibre isn't fully digested by the body and plays an important role in digestive health. Certain fibres, such as chicory inulin, also act as prebiotics, providing nourishment for beneficial gut bacteria. While fruits, vegetables, wholegrains, legumes, nuts, and seeds are all natural sources of fibre, supplements can help bridge the gap when daily intake falls short.
What different types of fibre are there?
Dietary fibre is generally grouped into two main categories: soluble and insoluble fibre.
Soluble fibre dissolves in water to form a gel-like substance in the digestive tract. Sources include oats, barley, and chicory root inulin. Certain soluble fibres also act as prebiotics, helping support beneficial gut bacteria.
Insoluble fibre does not dissolve in water and adds bulk to stool as it passes through the digestive system. It's commonly found in wholegrains, nuts, seeds, and vegetable skins.
Most fibre-rich foods contain a mixture of both types, and a varied diet typically provides a combination of each.
What is GLP-1?
GLP-1 (Glucagon-Like Peptide-1) is a naturally occurring hormone released in the gut after eating. It plays a role in appetite regulation and digestion and has become widely recognised due to the popularity of GLP-1 receptor agonist medications.
People following a GLP-1-focused nutrition approach often prioritise nutrients such as protein and fibre, as these can be more challenging to consume in sufficient amounts when overall food intake is reduced. Fibre supplements can provide a convenient way to support daily intake goals alongside a balanced diet.
Why might I need additional fibre or protein?
Protein and fibre are two nutrients that many people struggle to consume consistently in optimal amounts. Busy lifestyles, restrictive diets, reduced appetite, or simply not eating enough fibre-rich foods can make it difficult to meet recommended intakes.
Supplementing with fibre or protein can help fill nutritional gaps without requiring major dietary changes. Fibre supplements can help increase overall fibre intake, while protein supplements offer a convenient source of high-quality protein to support daily nutrition goals. They are designed to complement a healthy diet, not replace whole foods.
How much fibre do I need per day?
According to NHS guidelines, adults should aim for around 30g of fibre per day. However, average intake in the UK is significantly lower than this recommendation.
The amount of fibre provided by supplements varies by product. For example, a serving of Prebiotic Inulin Fibre Powder provides 12g of fibre, while High Fibre Gummies provide 3g per serving. Checking nutrition information can help you understand how a product contributes towards your daily target.
What fibre product should I choose?
The best fibre supplement depends on your preferences and routine. Prebiotic Inulin Fibre Powder is ideal if you want a high-strength, versatile fibre source that can be mixed into drinks, smoothies, yoghurt, or porridge.
High Fibre Gummies offer a convenient, no-preparation option that's easy to take on the go.
Synbiotic Gut Health Capsules combine prebiotics and probiotics in a simple capsule format.
100% Instant Oats, Protein Oatbakes, and Oat Protein Flapjacks provide fibre alongside carbohydrates and protein, making them suitable as part of a meal or snack.
If you're looking to increase your fibre intake with minimal disruption to your routine, choose the format you'll find easiest to use consistently.
