Supplemented food and dietary supplements

What supplemented food and dietary supplements are, and the rules for labelling and selling them.

Supplemented food

Supplemented products have been represented as food but have been modified or had substances added to perform a physiological role. They provide more than simple nutrition. For example, a supplemented product could be milk or yoghurt that has added folic acid.

Requirements for producing supplemented food

The New Zealand Food (Supplemented Food) Standard 2016 sets out what parts of the Food Standards Code do not apply to supplemented food.

Supplemented food incorporates most of the rules for general foods

Most of the regulatory requirements that apply to food under the Australia New Zealand Food Standards Code also apply to supplemented food.

Applying labelling and composition requirements

Supplemented food is different to food in that:

  • substances can be added to food so long as they are safe and suitable, and have not been restricted or banned (for example, vitamins and minerals)
  • The label must say "supplemented food".

They must not:

  • be specifically formulated for children under the age of 4
  • contain substances that are classified under the Medicines Act 1981. These are substances that have a therapeutic effect, or claim to have one.
