Science & evidence

D-Mannose is a simple sugar that is naturally found in some fruits. When ingested, it is absorbed slowly and largely excreted in the urine, rather than being metabolised by the body. This unique pathway allows D-Mannose to interact directly with bacteria in the urinary tract, which could help prevent them from adhering to the bladder walls.

By supporting the natural cleansing process, D-Mannose provides a non-antibiotic approach to maintaining urinary tract health.

Our high-strength D-Mannose capsules deliver a concentrated serving of this naturally occurring simple sugar. When consumed, D-Mannose passes through your body largely unchanged, reaching the urinary tract where it can help support the natural flushing process. This unique mechanism helps to maintain a healthy and balanced urinary environment.

Whether you’re looking for daily proactive support or a natural way to address urinary discomfort, D-Mannose is a smart daily choice for confident urinary tract health.

What's inside our D-Mannose supplement?

D-Mannose

D-Mannose is a naturally occurring simple sugar, structurally related to glucose, that is found in small amounts in various fruits and vegetables. It is absorbed into the bloodstream and then primarily excreted via the kidneys into the urinary tract, where it helps support the removal of bacteria.

Magnesium Stearate

Used as an anti-caking agent, which helps stop the powder from clumping, to ensure smooth production and a consistent dosage in every capsule.

HPMC Capsule Shell

Hydroxypropyl Methylcellulose (HPMC) is a plant-derived, vegan-friendly capsule material used as an alternative to gelatine.

Ingredient list

What is D-Mannose?

D-Mannose is a naturally occurring simple sugar, similar to glucose, but with a unique pathway in the body. Unlike other sugars, it is not extensively metabolised for energy. Instead, when consumed, it is absorbed and then largely filtered by the kidneys before passing into urine.

This specific metabolic route means D-Mannose can reach the urinary tract, where it may interact with certain bacteria, helping to support the body’s natural cleansing process and maintain urinary comfort.

Our capsules provide a convenient, concentrated way to include D-Mannose as part of your daily wellness routine.

FAQs

How does D-Mannose work?

D-Mannose is thought to bind to certain bacteria in the urinary tract, which may help reduce their ability to attach to the bladder walls. This allows them to be carried out naturally during urination, supporting the body’s normal cleansing process.

Can I take D-Mannose alongside other supplements?

Yes. D-Mannose is generally safe to take with other food supplements. However, if you are pregnant, breastfeeding, have a medical condition, or take prescription medication, we recommend checking with your GP before starting any new supplement.

Is D-Mannose suitable for long-term use?

D-Mannose is a naturally occurring substance and is generally considered safe for long-term use for urinary tract support. As with any supplement, consistency is key for best results. Always follow the recommended dosage.

What are the common sources of D-Mannose in food?

D-Mannose is found in small amounts in various fruits such as cranberries, blueberries, peaches, apples, and oranges, as well as some vegetables like green beans and broccoli. Our supplement provides a concentrated dose for targeted support.

D-Mannose: Scientific Resources & Clinical Studies

D-Mannose as a possible alternative for acute uncomplicated UTIs

A post hoc analysis of a non-interventional study found that D-mannose monotherapy produced symptom resolution rates similar to antibiotics in women with acute, uncomplicated UTIs.

Potential complementary role for recurrent UTIs

This narrative review suggests that D-mannose supplementation could help reduce recurrence of UTIs by inhibiting E. coli from adhering to the urinary tract lining.

Read study

 

D-Mannose doesn’t impact E. coli growth or antibiotic effectiveness

Laboratory tests showed that even at high concentrations, D‑mannose didn’t alter bacterial growth, metabolism, or susceptibility to antibiotics—and it didn’t affect the function of the FimH adhesin on E. coli. Overall, these results support D‑mannose as a neutral yet viable option in managing urinary tract infections in terms of safety and lack of interference.
