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 with benefits beyond those of normal nutrients, and to support or maintain 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:
- Vitamins, minerals, or amino acids (both natural and synthetic).
- Substances derived from natural sources, including non-human, animal and botanical materials in the forms of extracts, isolates, concentrates.
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.
If you are unsure of your product's classification, you can check using our Complementary Health Products (CHP) Classification Tool to assist you in the classification of common CHP.
