Liposoluble (fat-soluble) vitamins

Vitamin A

Vitamin A is essential for good vision, particularly in low light situations. It also helps to keep the skin and mucosal membranes in good condition, and has an effect on the immune system and on cell differentiation and growth.
Consumption of the first three groups of foods however (the richest in vitamin A) must remain within reason.
This vitamin is sensitive to oxygen and to light. Foods rich in vitamin A should preferably be stored for only short periods and packaging resealed firmly where applicable.

Vitamin D

Vitamin D plays two essential roles. Firstly it ensures optimal bone mineralisation during growth, and also throughout life for bone renewal. Secondly, it regulates the intestinal absorption of calcium and contributes to the stability of calcium concentrations in blood and tissues.
Some of our needs are covered by regular moderate exposure of the skin to sunlight.
To protect it correctly it is recommended that foods rich in vitamin D only be stored for short periods of time and always away from light. In addition, packaging must be resealed firmly where applicable.

Vitamin E

Vitamin E has anti-oxidant properties. It acts in particular on cell membranes and lipoproteins. This vitamin is sensitive to light. Foods rich in vitamin E should preferably be stored away from light.

Vitamin K

Vitamin K is essential for blood coagulation and promotes the binding of calcium onto the protein matrix of bone.
It is sensitive to oxygen and, in particular, to light. To best preserve it, foods rich in vitamin K should preferably be stored for only short periods of time and always away from light.
