In Singapore, health supplements fall under the scope of "complementary health products" and are regulated as "health products". A health supplement is a product that is used to supplement the diet, and to support or maintain the healthy functions of the human body. It cannot be an injectable/a preparation that needs to be sterile, such as injections and eyedrops; or any type of general food.
A health supplement must also contain one or more, or a combination of the following ingredients, and it must be administered in small unit doses in dosage forms such as capsules, softgels, tablets, liquids, syrups.
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.
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.

What's more, instead of the pre-market approval, HSA will conduct post-market surveillance to monitor the safety of health supplements and to initiate timely product recalls - This includes random sampling of products in the market and adverse reaction monitoring, which draws on HSA's network of healthcare professionals and international regulatory partners to pick up signals of adverse reactions to products. Products found to be unsafe will be withdrawn from the market.
