Regulatory overview of health supplements

Understand the requirements to import, manufacture or sell health supplements in Singapore.

What is a health supplement

A health supplement is a product that is used to supplement a diet and to support or maintain, enhance and improve the healthy functions of the human body. It cannot be an injectable or a preparation that needs to be sterile, such as injections and eyedrops. It cannot be an item of a meal or diet.

A health supplement must also contain one or more, or a combination of the following ingredients:

a. Vitamins, minerals, amino acid, fatty acids, enzymes, probiotics and other bioactive substances;

b. Substances derived from natural sources, including animal, mineral and botanical materials in the forms of extracts, isolates, concentrates; and

c. Synthetic sources of ingredients mentioned in (a) and (b).

A health supplement must be administered in small unit doses in dosage forms such as the following:

  • Capsules
  • Softgels
  • Tablets
  • Liquids
  • Syrups

Products used on animals, as well as products presented in the form of food and beverages, such as biscuits, cookies, coffee, and juice are not health supplements.

Food and supplements of food nature come under the purview of the Singapore Food Agency (SFA). View the interactive Food-Health Product Classification Tree1517 KB for more information.
