HSA Updates on Adulterated Health Products Found Overseas (Nov-Dec 2017)

The Health Sciences Authority (HSA) would like to update the public on adulterated health products found overseas between November and December 2017. This information is provided to increase awareness on safety issues of health products found overseas, which may impact the local population. Please refer to Annex A and Annex B of the pdf version for the list of adulterated health products and the possible side effects of the undeclared potent ingredients. 

Local Situation

2    To-date, these products are not detected to be sold in Singapore, but it is noted that some of these products may have been obtained from overseas sources by consumers.

HSA’s Advisory

3    Members of the public are advised to:

  • Stop consuming the products if you have purchased or are consuming any of them, and consult a doctor if you are feeling unwell.
  • Avoid buying any of these products when abroad.
  • Be wary of products that promise quick and miraculous results or carry exaggerated claims like “100% safe”, “no side effects” or “scientifically proven”. Consumers should also be cautious of products that produce unexpected quick recovery of medical conditions. Consult your doctor or pharmacist if you need help for the management of your acute and chronic medical symptoms and conditions (e.g. diabetes, hypertension, eczema).
  • Exercise caution when purchasing health products online or from sources (either local or overseas) which you may not be familiar with, even if well-meaning friends or relatives have recommended them. You cannot be certain where and how these products were made. They may be illegal, counterfeit or substandard, and may contain undeclared ingredients which can harm your health. If buying health products online, we encourage you to buy them from websites with an established retail presence in Singapore.

4    Additionally, members of the public are encouraged to visit to learn more about the dangers of buying health products from dubious sources.

5    Members of the public who come across the sale and supply of these adulterated products or other illegal products in Singapore may contact HSA's Enforcement Branch at Tel: 6866-3485 during office hours (Monday to Friday) or email:
