Dietary fibre consists of plant-based food components that are not fully digested in the small intestine and reach the large intestine. It occurs naturally in foods such as fruit, vegetables, pulses, nuts and whole grains.

A varied diet should be the main source of fibre. However, there are fibre supplements that can be used to supplement the diet in certain circumstances.

Fibre plays various roles within a balanced diet. Depending on the type of fibre and its characteristics, it can contribute to normal bowel function and help increase stool bulk.

Furthermore, certain types of fibre have specific properties. Therefore, when choosing a product, it is advisable to check which ingredients it contains and what purpose the manufacturer states it serves.

Dietary fibre can be broadly classified as soluble and insoluble fibre. Many foods and supplements contain a combination of both.

Soluble fibre

Soluble fibre has the ability to absorb water and can form gel-like substances during digestion. It occurs naturally in various fruits, vegetables, pulses and cereals.

Ingredients such as psyllium and glucomannan are sources of soluble fibre commonly used in food supplements.

Insoluble fibre

Insoluble fibre is found particularly in whole grains, bran, nuts and certain vegetables. It helps to increase stool bulk and forms part of a diet designed to maintain healthy bowel function.

Fibre supplements for bowel function can be an option for increasing fibre intake when an adequate amount cannot be obtained through diet alone.

It is important to drink plenty of fluids when taking fibre and always to follow the specific product instructions. An excessively rapid increase in fibre intake can cause digestive discomfort such as flatulence or abdominal bloating in some people.

Psyllium is a source of soluble fibre obtained from the seeds of species of the genus Plantago. It has the ability to absorb water and increase in volume, which is why it is used in various preparations designed to support bowel function.

Products containing psyllium fibre should be taken with a sufficient amount of liquid and in accordance with the manufacturer’s instructions.

Glucomannan is a soluble fibre derived from konjac which can be found in various food supplements. It has a high capacity to absorb water.

As part of a calorie-restricted diet and under the conditions of use set out for this claim, glucomannan contributes to weight loss. This does not mean that a glucomannan supplement alone causes a reduction in body weight.

It must be taken with plenty of water and in strict accordance with the product instructions, particularly for people who have difficulty swallowing.

Fibre-rich foods can form part of a healthy diet aimed at weight management. However, fibre supplements for weight loss are not a substitute for a balanced diet, nor do they guarantee weight loss on their own.

If the aim is to lose weight, it is more appropriate to adopt a comprehensive strategy based on a diet tailored to individual needs, physical activity and sustainable habits. Where necessary, a dietitian-nutritionist or healthcare professional can draw up personalised guidelines.

How you take a fibre supplement depends on its composition and form. Some products come as a powder to be dissolved in water, whilst others are available in sachets, capsules or tablets.

In all cases, it is important to:

• Stick to the recommended daily amount.
• Follow the recommended preparation instructions.
• Drink plenty of fluids.
• Do not exceed the recommended dose.
• Introduce the fibre gradually where appropriate.
• Check the specific warnings for the product.

The best time to take fibre supplements will depend on the type of product and its intended use. Follow the manufacturer’s instructions regarding timing, preparation and the amount of liquid required.

If you are taking medication, consult your doctor or pharmacist about whether you should take fibre supplements at a different time, as some products may affect the absorption of certain medicines.

A rapid increase in dietary fibre intake may temporarily cause wind, a feeling of bloating or changes in bowel habits. For this reason, it may be advisable to increase your intake gradually and ensure you stay well hydrated.

If the discomfort is severe, persistent or other digestive symptoms appear, consult a healthcare professional.
