Our mission

For more than 20 years, we have been specifically looking for substances in food that are beneficial for health in general and mental health in particular.

Over the years, we have realised that vitamins are important micronutrients in a balanced and healthy diet. But there are still some pieces missing in this complicated puzzle to explain the effect of a balanced diet on the health of the human organism.

Only by combining the expertise of our multinational team has it been possible, after 20 years of intensive scientific research, to discover an important new substance in the human food chain:

Vitamin A5, the first newly discovered vitamin in over 80 years.

Vitamin A5 is a very important component of a balanced and healthy diet.
