Vitamins + Minerals: Permitted Substances

Permitted substances in the EU + EEA according to COMMISSION REGULATION (EC) No 1170/2009 of 30 November 2009

Vitamins A-E are by no means uniform substances. In the case of vitamin B12, for example, there are at least 4 substances that act in the same way in the body, can be partially converted into each other and can therefore all be referred to as "B12".
Minerals cannot be taken in pure form, most people know from chemistry lessons, for example, what happens if you take potassium pure or combine it with water. See here: https://www.youtube.com/watch?v=i8DiLjGc3pA, so you should not try to cover your potassium needs with pure potassium! Therefore, minerals or trace elements must always be taken in the form of chemical compounds that are harmless to the body and from which the body can then extract the substances by digestion or transformation.
There is therefore a very wide range of chemical compounds that manufacturers of food supplements and medicines can use to enrich their products with vitamins and minerals.

Some of them are better utilised, some worse. Some are allowed in the EU, others can only be obtained from abroad because they are not allowed here, mostly because of safety concerns.

>In the past, many very good compounds were not permitted in Germany; the new EU Regulation No. 1170/2009 has brought significant improvements here. Important substances with a very high value, such as methylcobalamin or iron bisglycinate, were banned until then, now they are allowed, much to the benefit of consumers.

In our online shop you will only find selected products that contain substances with the highest availability. This distinguishes our range from the usual supermarket, drugstore and pharmacy products.
