OPTIFIBRE TIN

What Is OptiFibre Tin — a Soluble Fibre Supplement?

Getting enough fibre from food alone can be genuinely difficult. Whether it's a busy lifestyle, a restricted diet, or a digestive condition making things complicated, many people in the UK simply don't hit the recommended 30 g of fibre per day. OptiFibre Tin is a soluble fibre supplement designed to bridge that gap — quietly, conveniently, and without altering the taste of your food or drink. It contains partially hydrolysed guar gum (PHGG), a well-studied plant-derived fibre that dissolves completely in liquid, leaving no texture or flavour behind.

Bowel irregularity affects a significant proportion of the UK population at any given time. If you're looking for gentle, everyday support for your digestive system, OptiFibre is worth understanding properly. You can also explore our wider range of vitamins and supplements if you're building a broader wellness routine alongside your fibre intake.

How Does OptiFibre Work to Support Your Gut?

OptiFibre works through the action of partially hydrolysed guar gum, a soluble dietary fibre derived from guar beans. Unlike insoluble fibre, which adds bulk to stools, PHGG dissolves fully in water and acts in a more nuanced way throughout the digestive tract. Here's what happens when you take it:

• PHGG dissolves in liquid and passes into the small intestine largely intact.
• In the large intestine, gut bacteria ferment the PHGG, producing short-chain fatty acids (SCFAs) that nourish the gut lining.
• This fermentation process supports the growth of beneficial bacteria such as Bifidobacterium and Lactobacillus.
• The gel-forming properties of PHGG help regulate stool consistency — softening hard stools and firming loose ones.
• Gut transit time is normalised, reducing both constipation and diarrhoea symptoms over time.

This dual-action effect on stool consistency is one of the reasons PHGG is used in clinical nutrition settings as well as everyday supplementation.

Who Should Consider Using OptiFibre Tin?

OptiFibre is suitable for a broad range of people. It's particularly useful if you struggle to meet daily fibre requirements through diet alone, or if you have a digestive condition that makes high-fibre foods uncomfortable. It's tasteless and odourless, which makes it easy to incorporate into almost any meal or drink without noticing it's there.

OptiFibre may be appropriate for you if you:

• Experience occasional or chronic constipation and want a gentle, non-stimulant option.
• Have been diagnosed with irritable bowel syndrome (IBS) and need a low-FODMAP-compatible fibre source.
• Are recovering from illness or surgery and need to restore bowel regularity gradually.
• Are an older adult whose dietary fibre intake has declined.
• Are a parent looking for a fibre supplement suitable for children over three years of age.

If you're managing IBS alongside constipation, our IBS and cramps collection may also have relevant products to support your overall digestive health plan.

How Does OptiFibre Compare to Other Fibre Supplements?

Is OptiFibre Tin Suitable for Long-Term Use and How Should It Be Stored?

OptiFibre Tin can be used as part of a long-term dietary strategy to maintain bowel regularity. Because it works by supplementing dietary fibre rather than stimulating the bowel artificially, it does not carry the dependency risks associated with stimulant laxatives. That said, if you're using it to manage a specific condition, it's worth reviewing your approach with a pharmacist or GP periodically.

Store the tin below 25°C in a dry place, away from direct sunlight. Always keep the lid tightly closed after use to prevent moisture from affecting the powder. Do not use after the expiry date printed on the base of the tin. If you're also managing constipation with other products, our constipation collection offers a range of complementary options.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is OptiFibre Tin and What Is It Used For?

OptiFibre Tin is a dietary fibre supplement containing partially hydrolysed guar gum (PHGG) as its sole active ingredient. It is used to increase daily fibre intake in people who cannot meet their requirements through diet alone. Clinically, it is used to support bowel regularity in both constipation and loose stools, making it one of the few fibre supplements with a genuinely bidirectional effect on gut transit. It is also used in clinical nutrition to support patients with IBS, post-surgical bowel recovery, and age-related reductions in dietary fibre intake.

Because PHGG is fully soluble and tasteless, it can be stirred into water, juice, tea, soup, or soft foods such as yoghurt without altering flavour or texture. This makes it particularly practical for older adults, children over three, and anyone who finds high-fibre foods difficult to tolerate.

What Do You Need to Know Before Using OptiFibre Tin?

OptiFibre is generally well tolerated, but there are some important considerations before you start. Always read the label carefully and speak to your pharmacist if you are unsure whether this product is right for you.

Do not use OptiFibre if you:

• Have galactosaemia (a rare inherited metabolic disorder).
• Have a known allergy or hypersensitivity to guar gum or any other ingredient in the product.
• Have difficulty swallowing or a known oesophageal obstruction — always mix thoroughly in adequate liquid.
• Are experiencing sudden, unexplained changes in bowel habit lasting more than two weeks without a confirmed diagnosis — see your GP first.

Use with caution and speak to your pharmacist or GP if you:

• Are pregnant or breastfeeding — while dietary fibre is generally considered safe, always seek professional advice.
• Have a history of bowel obstruction or severe gastrointestinal narrowing.
• Are taking other medicines, particularly those with a narrow therapeutic index.

Drug interactions:

• Soluble fibre may slow the absorption of some oral medications if taken simultaneously. As a precaution, take other medicines at least one hour before or two hours after OptiFibre.
• No specific clinically significant drug interactions have been established for PHGG at standard doses.

How Should You Use OptiFibre Tin?

OptiFibre is straightforward to use, but getting the preparation right matters — particularly ensuring you drink enough fluid alongside it. Start with a lower dose and build up gradually over the first week to allow your digestive system to adjust.

1. Measure one scoop (approximately 5 g) of OptiFibre powder using the scoop provided.
2. Stir the powder into at least 150 ml of water, juice, or another suitable liquid until fully dissolved.
3. Drink immediately — do not allow the mixture to stand, as it may thicken slightly over time.
4. Alternatively, stir into soft food such as yoghurt, porridge, or soup.
5. Drink at least 6–8 glasses of fluid throughout the day to support the fibre's action.
6. Increase the dose gradually if needed, up to the maximum recommended daily amount.

If you are also managing diarrhoea alongside your fibre intake, our diarrhoea collection includes additional products that may complement your treatment plan.

What Are the Possible Side Effects of OptiFibre Tin?

Like all fibre supplements, OptiFibre can cause some digestive side effects, particularly when you first start taking it or increase the dose too quickly. Most side effects are mild and resolve within a few days as your gut adjusts.

Common side effects:

• Bloating
• Flatulence (wind)
• Mild abdominal discomfort or cramping

Less common side effects:

• Loose stools or mild diarrhoea if the dose is increased too rapidly
• Nausea (rare, usually associated with insufficient fluid intake)
• Allergic reaction — seek immediate medical attention if you develop rash, swelling, or difficulty breathing

To minimise side effects, always start with the lowest recommended dose and increase gradually. Drinking plenty of water throughout the day is essential.

How Should You Store OptiFibre Tin?

Correct storage keeps the powder effective and safe to use throughout its shelf life. Follow these instructions:

• Store below 25°C in a cool, dry place.
• Keep away from direct sunlight and sources of heat or moisture.
• Always replace the lid firmly after each use.
• Do not use after the expiry date printed on the base of the tin.
• Keep out of the reach and sight of children.
• Do not store in the bathroom or near a sink — humidity can affect the powder.

If you're building a broader digestive health routine, our indigestion collection includes products that may work alongside OptiFibre to support overall gut comfort.
