AGROLAB POLSKA together with AGROLAB LUFA offer vitamin, mineral and trace element analysis in food supplements to ensure that your product complies with the recommendations. It is also important to check the composition at the end of the minimum shelf life, as vitamins are sensitive and may degrade over time. Some producers tend to compensate for these losses by an overdosing which bears the risk to exceed the maximum levels.
