Shop Glucomannan at Holland & Barrett

Glucomannan is a natural fibre. Here you’ll find a dedicated range of glucomannan supplements, so you can choose the format that fits easily into your day and works with your lifestyle.

What is glucomannan?

Glucomannan comes from the konjac plant, a root traditionally used in parts of Asia. The fibre from this root absorbs water and forms a gel‑like texture. Many people choose glucomannan as one part of a wider wellbeing plan, alongside movement, mindful eating, and quality sleep.

Glucomannan supplements: formats to fit your day

Our glucomannan range is designed to give you options. You’ll typically find:

• Easy-to-take capsules – a popular choice if you prefer something quick and simple with a glass of water. Glucomannan capsules can be a convenient way to include this fibre in your day, especially if you’re often on the go.
• Powders and drink mixes – ideal if you like to sip your supplements. These can be mixed with water to create a drink you can take before meals, fitting around your schedule.

Each product will have its own directions on the label, so it’s always worth checking the packaging before use.
