If a supplement causes a harmful reaction, you can report it three ways: tell your health care provider, notify the FDA (by phone at 1-800-FDA-1088 or through its online Safety Reporting Portal), and tell the manufacturer using the contact information on the label. Reporting helps the FDA spot dangerous products, since supplements are not approved before sale.

Key Takeaways

  • Because supplements aren't approved before sale, the FDA relies on after-the-fact reports to catch problems.
  • Report a reaction three ways: your clinician, the FDA, and the manufacturer.
  • The FDA's MedWatch line is 1-800-FDA-1088, with an online Safety Reporting Portal as well.
  • Include the product name, lot number, dose, duration, and your symptoms — and keep the bottle.
  • For a severe reaction call 911; for a suspected poisoning call Poison Control at 1-800-222-1222.

Why reporting matters

Dietary supplements are not reviewed by the FDA before they go on sale, so the agency depends heavily on after-the-fact reports to catch dangerous or contaminated products [1]. When you report a reaction, you add a data point that can help the FDA detect a pattern and act — exactly how several tainted or mislabeled products have been pulled in the past. (For the bigger picture, see how the FDA regulates supplements.)

What counts as an adverse event

An adverse event is any harmful or unexpected reaction you associate with a supplement — for example a rash, racing heart, stomach problems, dizziness, or signs of liver trouble. You do not need to be certain the supplement was the cause; suspected reactions are worth reporting.

Three ways to report

1. Tell your health care provider. They can evaluate you, manage the reaction, and submit a report on your behalf. The NIH Office of Dietary Supplements advises letting your provider know about any problem [1].

2. Report to the FDA directly. Call 1-800-FDA-1088 (the MedWatch line) or file online through the FDA's Safety Reporting Portal [2]. MedWatch is the FDA's adverse-event reporting program.

3. Tell the manufacturer. Use the contact details on the product label; companies are required to forward serious adverse-event reports to the FDA.

What to include

  • The exact product name, brand, and (if possible) the lot or batch number.
  • The dose you took and how long you had been taking it.
  • The symptoms, when they started, and how they progressed.
  • Other supplements and medicines you take, since interactions matter.

Keep the bottle if you can — the label and lot number are valuable for any investigation.

When it is an emergency

Reporting is for surveillance, not emergencies. For a severe reaction — trouble breathing, swelling, fainting, or other urgent symptoms — call 911. For a suspected poisoning, contact Poison Control at 1-800-222-1222.

Frequently Asked Questions

Do I have to be sure the supplement caused my reaction to report it?

No. Suspected reactions are worth reporting even if you are not certain of the cause. The FDA looks for patterns across many reports, so your submission is useful even when the link is not definite. Reporting is about flagging a possible problem, not proving it.

How do I report a supplement problem to the FDA?

Call the MedWatch line at 1-800-FDA-1088 or file a report through the FDA's online Safety Reporting Portal. You can also ask your health care provider to submit a report, and you should notify the manufacturer using the contact details on the label.

What information should I have ready?

The product name and brand, the lot or batch number from the label, the dose and how long you took it, a description of your symptoms and their timing, and a list of your other supplements and medicines. Keeping the actual bottle is very helpful.

What should I do in an emergency?

Reporting systems are for surveillance, not urgent care. If you have a severe reaction such as trouble breathing, swelling, or fainting, call 911. For a suspected poisoning, including a child swallowing supplements, call Poison Control at 1-800-222-1222 right away.
