What is D Mannose?
D Mannose is a simple sugar that belongs to the monosaccharide group. It is closely related to glucose and has a similar chemical structure, but with a small difference in the arrangement of the molecule.
These subtle structural differences mean that D Mannose is considered a distinct type of sugar. In nature, it occurs as part of more complex carbohydrates, such as polysaccharides and glycoproteins.
Where does D Mannose occur naturally?
D Mannose occurs in small amounts in various foods. It is found in certain fruits, including cranberries, apples and peaches.
D Mannose is also found in plant structures, where it forms part of more complex carbohydrates. Microorganisms and certain plants can also contain D Mannose.
The amount of D Mannose in food is generally relatively low and can vary depending on factors such as the product's origin, ripeness and processing.
What is the difference between D Mannose and other sugars?
Although D Mannose belongs to the same group as sugars such as glucose and fructose, there are clear differences in structure and properties.
D Mannose is what is known as an epimer of glucose. This means that its molecular structure is largely the same, but differs at one point. This small structural difference means that D Mannose is considered a separate sugar.
D Mannose also differs slightly in taste. It has a mildly sweet taste, but is often perceived as less sweet than table sugar, for example.
In foods and supplements, D Mannose is therefore not used as a standard sweetener, but as a specific, distinct form of carbohydrate.
What forms of D Mannose are available?
D Mannose is available in various supplement forms and is often combined with other ingredients in multi-ingredient formulas.
You will find several D Mannose products in our range. These include a formula with cranberry concentrate and D Mannose from Pure Encapsulations, which uses a carefully processed whole cranberry concentrate combined with a clearly specified dose of D Mannose.
There is also a liquid formula from Nature’s Answer, which combines D Mannose with cranberry and bearberry leaf. This liquid version offers an alternative way to take it and contains a concentrated blend of several ingredients.
