01 / THE DETAILS

What’s inside this formula?

NOW Foods’s D-Mannose — 500 mg is listed here in the d-mannose collection. This article looks at the selected 120 veg capsules; 40 servings pack, then puts its ingredients into context.

FROM THE MANUFACTURER’S LABEL

The manufacturer lists 1,500 mg D-mannose per three capsules, equivalent to 500 mg per capsule. The selected pack contains 120 capsules. D-mannose is a sugar, not an antibiotic.

D-mannose is a sugar promoted for urinary health because of a proposed effect on bacterial attachment. That mechanism has not translated into reliable prevention benefit in a large community trial. A clear product description should distinguish the biological theory from the outcomes people actually care about, such as fewer symptomatic infections.

The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.

02 / BENEFITS, IN PERSPECTIVE

Where might it be useful?

01

A researched mechanism

D-mannose has been investigated for interfering with attachment of some urinary bacteria.

02

No established routine prevention benefit

A large randomized trial did not show a meaningful reduction in medically attended recurrent UTIs.

THE EVIDENCE LENS

What the research can — and cannot — tell us

The 2024 placebo-controlled trial in women with recurrent UTIs did not support routine D-mannose prevention in primary care. Earlier small positive studies should be considered in that context. This is not evidence of treating an active infection, and a new branded formulation cannot inherit an unproven benefit.

03 / A CLOSER LOOK

What deserves your attention?

This is not a treatment for an active urinary tract infection. A large 2024 trial of D-mannose did not prevent recurrent UTIs in women; that study did not test this specific product. Do not delay medical care for urinary symptoms. Check suitability with a clinician during pregnancy, with kidney disease or when using medicines.

Suitability comes before strength

Do not delay assessment or prescribed treatment for urinary symptoms. Fever, flank pain or symptoms in pregnancy need prompt advice. Review supplement use with a clinician when managing diabetes or recurrent infections.

Dietary details for this product

Vegan The official page identifies the formula as vegan/vegetarian and lists a hypromellose capsule with vegetable-source stearic acid and magnesium stearate.

A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
