What FDA Warning Letters Are and Why You Should Know About Them

December 8, 2025 Category: Consumer Safety / Healthcare Fraud

Hello everyone! So far we've talked a lot about medications that the FDA approves. But what happens with those that it does not approve and that, nevertheless, someone tries to sell you?

Today we explore a lesser-known but vital section of the FDA website: the list of Advisory Letters. This is, basically, the "wall of shame" for companies that market illegal products promising to cure serious diseases without any scientific proof.

What are these letters?

Imagine that a company starts selling a supplement on the internet saying that it "cures cancer" or "eliminates diabetes". The FDA monitors this and, when it detects these dangerous claims, it sends a notification.

If the company doesn't correct its behavior or doesn't remove those false claims, it ends up on this public list. The objective is clear: to protect you.

What we're seeing in 2025

When reviewing the current list, we see a concerning trend that you should be aware of:

• "Miraculous" Kits: Companies selling supplement packages for complex conditions like autism, autoimmune diseases or parasites (recent examples include HerbBaby, Inc. or Quit Kit, LLC).

• Patches and Drops: Topical products that promise to detoxify lungs or treat addictions without any real medical basis.

• "Natural" Cures: Many of these products hide under the label of "natural" or "herbal", but making claims that they cure serious diseases (like Parkinson's or heart problems) is illegal and dangerous if it leads patients to abandon their real treatments.

Why is it important to review this?

For patients and family members, this list is a verification tool. If you see an ad on social media for a product that sounds too good to be true, a quick search in this database could save you from a scam or harm to your health.

For doctors, it's a valuable resource to alert patients about trendy products that could interact with their prescription medications.

The final message

Not everything that glitters on the internet is medical gold. The FDA keeps this list updated so we can distinguish between real science and deceptive marketing. Before you buy that "miraculous remedy", take a look at the official warnings.
