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.

Pop, flip & supp
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 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.

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.
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.
Food supplements should not be used as a substitute for a varied, balanced diet and healthy lifestyle.
