Gut health supplements are products designed to support digestion, digestive function or the gut microbiome. Common types include probiotics, prebiotics, digestive enzymes and fibre supplements.

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Different probiotic supplements can contain different species and strains, so their formulations aren't interchangeable.

Prebiotics are substances that are selectively utilised by microorganisms in the body and provide a health benefit. Certain fibres and carbohydrates can function as prebiotics.

The simplest distinction is that probiotics contain beneficial live microorganisms, whereas prebiotics provide compounds that certain microorganisms can use. Some products combine both approaches.

Digestive enzymes are substances that help break food down into smaller components during digestion. Different enzymes act on different nutrients, including protein, carbohydrates and fat.

Yes. Dietary fibre is an important part of a healthy diet and helps support normal bowel function. Fibre-rich foods should generally form the foundation, while supplements can provide additional fibre when required.

It depends on the product. Probiotics, digestive enzymes, prebiotics and fibre supplements can have different directions for use, so follow the instructions provided with the individual supplement.

Many gut health supplements are formulated for regular use, but suitability depends on the specific product, ingredients and serving size. Follow the manufacturer's directions and avoid unnecessarily doubling up on similar ingredients.
