D-mannose is a natural monosaccharide, a simple sugar, that is chemically classified as a hexose, specifically an aldohexose. This means that it has six carbon atoms and contains an aldehyde group.

D-mannose is a close relative of glucose, but differs in the arrangement of its atoms, resulting in different physiological behavior in the body.

This structural difference means that D-mannose is only minimally involved in energy metabolism like classic sugars - most of it is not consumed by the body as an energy source, but is excreted in the urine.

In nature, D-mannose is found in small amounts in fruits, especially cranberries, apples, pears, peaches, oranges, and some berries. It is also a component of some plant polysaccharides and glycoproteins in both plants and animals.

From a technological point of view, for the production of dietary supplements, it is usually obtained from corn glucose through an enzymatic process that allows the separation and stabilization of the pure form of D-mannose in powder. This powder is then filled into capsules that allow for practical and precise dosing.

In the human body, D-mannose is particularly interesting because it is a component of some glycoproteins found on the surface of cells. Glycoproteins play an important role in intercellular communication, in the recognition of molecules, or in the protection of cells from external influences.

For example, in cell membranes, D-mannose can be part of so-called mannose residues, which are involved in various biological interactions. Its specific adhesion to certain structures is being studied in connection with the functions of the urinary tract, where it naturally occurs in urine, and it is there that it is believed to play an interesting physiological role.

In the production of nutritional supplements, D-mannose is most often obtained from glucose by an enzymatic process, the goal being to achieve maximum purity and biological stability of the substance. In our case, we use modern SmartPure® technology , which represents an advanced production process aimed at gentle processing of the raw material without unnecessary chemical additives.

SmartPure® ensures high purity of D-mannose without residues and contaminants, which is important for preserving its natural structure and biological integrity. This technology also helps to achieve better absorbability and reduce the occurrence of undesirable substances, thereby supporting a high standard of quality of the resulting product.

D-mannose in capsule form is thus produced in a pure and stable powder state, which is enclosed in gelatin or vegetable capsules for easy use. This method of dosing ensures accuracy and convenience, while eliminating the need for artificial sweeteners, colors or preservatives. Thanks to SmartPure® technology, the resulting product is extremely pure, making it suitable even for more demanding consumers who value quality and naturalness.

After ingestion, it is rapidly absorbed in the upper part of the small intestine, without causing a significant increase in blood sugar levels. This means that it does not represent a significant glycemic load. After absorption, it enters the bloodstream and from there travels directly to the kidneys, where it is filtered into the urine. Since the body does not use it as glucose, its presence in the urine is relatively rapid and unchanged.
