Report a Supplement

Written by the Neoi - Health Supplements Singapore editorial team - Last updated: 23 July 2026

To report a supplement concern in Singapore, first separate an unwanted health event, a suspicious sale, an advertisement complaint, and a refund dispute. Each has a different route. This guide is educational information, not medical or legal advice, and it does not determine whether a product or seller has broken a rule.

Match the concern to the correct route

Original element 1, captured on 23 July 2026: this concern map combines the live reporting instructions from HSA's illegal-health-product page, HSA's adverse-event page, HSA's feedback page, and the ASAS advertisement complaint page.

What you observed First official route to check What that route is for
You felt unwell after using a supplement Doctor or pharmacist, then HSA adverse-event information Health assessment and reporting an unwanted event
A seller may be offering an illegal, counterfeit, or suspicious health product HSA consumer-safety reporting route Information about possible illegal sales or supply
A supplement advertisement appears misleading ASAS online complaint route Complaints about advertisements
The dispute is about a refund, delivery, or warranty Consumer dispute route rather than the HSA enforcement route Seeking help with a transaction dispute

One concern can involve more than one row. Preserve each fact, but do not assume that one complaint form resolves every part.

Report suspicious sales to HSA

HSA's public reporting page asks people to report suspicious sales involving illegal health products to its Enforcement Branch. Incomplete information may limit follow-up. Its feedback page asks for the seller's name, location and contact information, the listing URL, and product information.

That route is relevant to a suspicious seller, possible counterfeit item, prohibited product, or illegal supply. It is not an authenticity certificate. HSA says feedback is assessed, but investigation status and outcomes may not be shared.

For an overseas website, record the platform and seller location. HSA notes that overseas platforms fall outside its direct control, although it may seek assistance from foreign counterparts.

Separate ads from purchase disputes

The ASAS online form is specifically for advertisement complaints. The live page directs consumer issues such as refunds, deliveries, and warranties to CASE instead. HSA likewise states that its illegal-product feedback route cannot advise on refunds or disputes arising from the sale of goods.

If your concern is an advertisement, save the exact claim, placement, advertiser or seller, and observation date. For a refund, keep the receipt, order and delivery records, and correspondence. When both are involved, prepare two clear records.

Do not include more personal information than a form requests. ASAS specifically warns users not to submit documents containing NRIC or passport details through its advertisement complaint page.

Build a six-field evidence pack

Original element 2, captured on 23 July 2026: this evidence pack translates the live HSA and ASAS instructions into one reusable record. It is a documentation aid, not proof that an offence occurred.

  1. Product: photograph the front, ingredient panel, warnings, batch or lot code, expiry details, and responsible-company information.
  2. Seller: record the displayed seller name, location, contact details, shop URL, and platform.
  3. Claim: save the exact advertisement or listing wording without paraphrasing it into a stronger claim.
  4. Transaction: keep the order date, receipt or invoice, payment record, delivery record, and refund correspondence where relevant.
  5. Timeline: note when the listing was seen, when the product was obtained, and when the concern arose.
  6. Health event: if you felt unwell, retain the pack and current label for a doctor or pharmacist; avoid publishing private health details in public reviews.

Use screenshots that show context, not isolated words. Keep the original URL and capture date beside each screenshot.

If the supplement made you unwell

HealthHub's HSA-contributed Understanding Health Supplements page says that someone who suspects a supplement is making them unwell should see a doctor or pharmacist immediately. HSA also maintains an adverse-event page with online and manual reporting routes, including a form for complementary health products such as health supplements.

Do not use a complaint checklist to decide whether symptoms are serious, to diagnose their cause, or to change prescribed treatment. Bring the product, label, ingredient list, dose used, timing, and other medicines or supplements to the professional reviewing the concern. Reporting and medical care are related but different tasks.

FAQ

Does reporting mean HSA has confirmed the product is illegal? No. A report provides information for assessment. It is not a finding, endorsement, recall, or authenticity decision.

Can HSA obtain my refund? HSA's feedback page says it cannot advise on refunds or sale-of-goods disputes and points consumers to CASE for refund assistance.

Where should I report a misleading supplement advertisement? The ASAS online complaint page is for advertisement complaints. Preserve the exact ad, advertiser, placement, URL, and capture date.

What if I both felt unwell and had a refund dispute? Seek health advice first, preserve the product and records, then use the relevant reporting and consumer-dispute routes separately.
