Dietary Supplement Testing

Importance of dietary supplements

 

Dietary supplements are foods that serve to supplement one’s diet. These are usually offered in the form of tablets or capsules. In this way, the body can be supplied with additional vitamins or minerals which it does not receive through diet, due to lifestyle or individual diet needs. For example, pregnant women often take folic acid in the form of a dietary supplement. Vegans supplement their diet with vitamin B12, and people who spend little or no time outdoors supplement with vitamin D.

Dietary supplements have become increasingly important in recent years. In Germany, about one in three people consumes dietary supplements. In the USA, it is one in two.

The most popular dietary supplements include magnesium, vitamin C, vitamin B12, calcium and iron supplements. Currently, there is no EU-wide regulation for the maximum amount of vitamins, minerals or other substances with a nutritional effect in food supplements.

Legal requirements for dietary supplements

1. Food Information Regulation (FIC)

 

EU: Regulation (EU) No. 1169/2011 contains the general labeling requirements for all foods and therefore also food supplements. Thus, the mandatory information such as a list of ingredients, the best-before date, the filling quantity and the name of the manufacturer must also be provided. However, the mandatory declaration of nutritional values according to Article 29-35 does not apply to food supplements.

USA: Title 21 CFR 101 Part A contains the general labeling requirements for all foods and therefore also food supplements. Thus, the mandatory information such as the statement of identity (name of the dietary supplement), the net quantity of contents statement (amount of the dietary supplement), the nutrition labeling, the ingredient list, and the name and place of business of the manufacturer, packer, or distributor. However, some elements/requirements listed are specific to food and some are specific to supplements.

 

2.  Directive 2002/46/EC of the European Parliament and of the Council

 

EU: Directive 2002/46/EC specifies which vitamins and minerals may be used in food supplements. However, according to Article 6 of the regulation, other nutrients such as amino acids, essential fatty acids, dietary fiber, and plant and herbal extracts are also permitted as ingredients. However, these are not yet regulated here.

USA: There are no specific requirements for vitamins, however for additives in general:

  • Title 21 CFR 170 covers all regulations for additives used in food and dietary supplements.However, only non-dietary ingredients added to a dietary supplement must be used in accordance with a food additive regulation or be GRAS for their intended use.The Food Drug and Cosmetic Act (See Section 413(d) of the FD&C Act, 21 U.S.C. 350b(d).) specifies that any manufacturer wishing to use “new dietary ingredients” (ingredients not in use prior to October 15, 1994) must notify the FDA of such ingredients.

 

3. Regulation on nutrition and health claims

 

EU: Regulation (EC) No. 1924/2006 lists the nutrition and health claims that may be made on the packaging of a product under food law. A health claim is a claim that establishes a relationship between a food product and health.

USA: Regulation on nutrition content claims and health claims

  • Title 21 CFR 101 Part D & Elists the nutrition content and health claims that may be made on the packaging of a product under food law. A health claim is any claim […] that expressly or by implication […] characterizes the relationship of any substance to a disease or health-related condition.

 

4. Regulation setting maximum levels for contaminants

 

EU: Regulation (EC) No. 1881/2006 sets maximum levels for certain contaminants in food. This ensures that food supplements do not contain undesirable concentrations of e.g. heavy metals.

USA: There are no specific regulations regarding maximum amounts, only Good Manufacturing Process Guidelines and Compliance Policy Guidelines (CPGs)

  • Current Good Manufacturing Practice in Manufacturing, Packaging, Labeling, or Holding Operations for Dietary Supplements
  • Dietary Supplement Health and Education Act of 1994 (DSHEA)
