Food Supplements


Food supplements are considered to be foodstuffs, even if they have some specificities, such as dosage form and are intended to complement or supplement a normal diet. They are not medicinal products and therefore cannot claim prophylactic properties, prevent or cure diseases, nor refer to such properties.


In accordance with Decree-Law no. 118/2015 of 23 june, which amends Decree-Law no. 136/2003, food supplements may only be made available to the final consumer in the form of a pre-packaged product.

They are intended to complement and / or supplement the normal diet and should not be used as a substitute for a varied diet.

They are concentrated sources of certain nutrients or other nutritional or physiological substances, on their own or in combination.

They may contain a wide range of nutrients and other ingredients, namely vitamins, minerals, amino acids, essential fatty acids, fiber and various plants and herbal extracts.

At Community level, only vitamins and minerals that can be incorporated into food supplements, which are discriminated in REG. (EC) no. 1170/2009, of the Commission of 30 November.

In addition to a list of authorized vitamins and minerals (Annex I), this diploma also contains a list of the ways in which nutrients can be incorporated as ingredients in food supplements (Annex II).

Substances other than vitamins and minerals, to be used as food supplement ingredients, must meet the requirements of REG.  (UE) No 2015/2283, concerning novel foods and novel food ingredients. It should therefore be possible to establish a significant food consumption history in the European Union before 15 May 1997 (the date of entry into force of that Regulation).

In the absence of any valid reference to the consumption of a particular food or ingredient in this context, it is considered that if a novel food or food ingredient is present and its marketing in the EU depends on a safety assessment carried out by EFSA and subsequent approval by the Commission.

It is the responsibility of the trader to ensure that the ingredients in food supplements are not novel foods. For more information on novel foods, see the DGAV page on this subject [Novel Foods]. 

In order to better protect consumer safety, the European Commission, at the request of a MS, may decide to include a substance or an ingredient in a list of prohibited substances, restricted substances or a list of substances under Community control, in accordance with the provisions of REG (EC) No. 1925/2006.

However, to date, only the species of Ephedra and Pausinystalia yohimbe have been harmonized: REG. (EU) No. 2015/403 of 11 March, amending Annex III to the Reg. (EC) No. 1925/2006 of the European Parliament and of the Council as regards the species of Ephedra and the Red-bellied Woodpecker [Pausinystalia yohimbe (K. Schum) Pierre ex Beille].
Ephedra species have been included in Part A of Annex III to Regulation (EC) No. 1925/2006 (Prohibited Substances) and Part C of that Annex, Pausinystalia yohimbe.

Products classified as medicinal products for human use as defined in Decree-Law No. 176/2006  of August 30, are not food supplements.

(EU) No. 1169/2011, Regarding the Information to the Consumer and REG. (EC) No. 1170/2009, on the addition of vitamins and minerals.
