Where D-Mannose Comes From
D-Mannose is a monosaccharide — a simple sugar in the same chemical family as glucose and fructose. It is found in relatively small amounts in cranberries, apples, peaches, oranges and blueberries. It is also present naturally in the human body, where it is involved in glycoprotein synthesis — the process by which proteins are modified with sugar molecules. The D-Mannose used in this supplement is produced to pharmaceutical purity standards and is the natural D-form, not a synthetic analogue.
Making It Part of Your Routine
D-Mannose is typically taken with water or unsweetened juice. The standard approach is 3 capsules (1500mg) per serving, with 1–3 servings per day depending on your preference and the guidance of a healthcare practitioner. As a food supplement with no specific daily upper limit established, dosing is adjusted according to individual use. The 90-capsule bottle provides 30 servings at 3 capsules per serving (1 serving per day), or fewer servings when used at higher daily frequency. Store in a cool, dry place and keep out of reach of children.
D-Mannose in Context
D-Mannose is one of the most researched single-ingredient supplements in women's nutritional health. Published research has focused on its behaviour in the urinary tract, where it is not metabolised in the same way as glucose but passes through the body relatively intact. It has no approved health effect on the GB nutrition register. It is a food supplement offered for those who have researched D-Mannose and are looking for a reliable, clean-formula source.

Frequently Asked Questions
Is Precision D-Mannose suitable for vegans?
Yes. All ingredients are plant-based. The HPMC capsule shell contains no animal-derived ingredients and the D-Mannose is produced through fermentation, not from animal sources.
Can people with diabetes or blood sugar concerns take D-Mannose?
D-Mannose is a simple sugar but is metabolised differently from glucose — it is largely excreted unchanged. However, if you have diabetes or a blood sugar-related condition, consult your doctor before use as any sugar-based supplement warrants medical consideration.
How many capsules should I take and when?
Three capsules (1500mg) per serving, taken 1–3 times daily with water or unsweetened juice. Do not exceed the recommended amount without guidance from a healthcare practitioner. The 90-capsule bottle provides 30 servings at 3 capsules per serving.
Is there a difference between D-Mannose powder and capsules?
The active ingredient is the same. Capsules offer convenience — pre-measured doses, no taste, easy to take anywhere — whereas powder may offer flexibility in dosing. Both forms are equally valid; the choice is personal preference.
Can I take D-Mannose alongside other supplements?
D-Mannose is a simple sugar with no known interactions with most supplements. If you are taking medication, speak to your healthcare practitioner before adding any new supplement to your routine.
