One single production may be divided in a variety of smaller operations, for instance in cases where the product is available in several countries or in different box sizes. With some products there may be different rules, so two identical products end up as either a food supplement in one country or a medical drug in another.
For this reason, all products are manufactured in accordance with the highest standard. A product that is manufactured as a medical drug can easily be sold as a food supplement. This is not the case the other way around.
