Hidden drugs in diet pills
Hidden Drugs in Weight-Loss Pills: What the FDA Warns and How to Protect Yourself
The FDA warns that many products sold as diet pills, fat-burning pills or weight loss supplements are likely contaminated with dangerous hidden ingredients, which it calls health fraud. One example is sibutramine, a drug removed from the US market in October 2010 for safety reasons. We found no FDA notice naming Trimoryn, and we do not suggest it contains any hidden drug.

The warning01
What does the FDA warn about weight-loss pills?
The FDA says many products sold as diet pills or weight loss supplements are likely contaminated with dangerous hidden ingredients, and it calls this health fraud 1.
Some makers add drug ingredients to avoid FDA review. The agency's example is a weight loss product that contains sibutramine, a banned weight loss drug, yet is called an all-natural supplement 2. Such products often have many positive reviews and are shared on social media, and they can cause severe illness and hospitalization. That is why a happy review is not a safety check.
We found no FDA notice that names Trimoryn, and we do not say or imply that it contains a hidden drug. Our aim is general: how to protect yourself with any product of this kind.
Sibutramine02
What is sibutramine?
Sibutramine is a prescription weight loss drug that the FDA removed from the US market in October 2010 for safety reasons 3.
It is known to substantially raise blood pressure and heart rate in some people and is a risk for people with a history of coronary artery disease, heart failure, arrhythmia or stroke. FDA laboratory analysis of some products found it, and also phenolphthalein, a laxative ingredient. Neither belongs in a supplement, and neither would be on a label if hidden. If you take a product and your heart pounds, you feel faint or have chest pain, stop and call 911.
| Fact | What FDA says |
|---|---|
| Name | Sibutramine, a banned weight loss drug |
| Removed from US market | October 2010, for safety |
| Risks | Raises blood pressure and heart rate in some people |

Red flags03
What are the red flags in a diet pill ad?
Red flags are claims that seem too good to be true, words like all natural, and many rave reviews 2.
- Promises of big, fast changes with no effort.
- Words such as natural, herbal or a proof claim with no study named 4.
- Famous names or doctors with no real link 5.
- Many glowing reviews and no way to check them 6.
- No maker named, or a label that hides amounts in a blend.
- A lot of urgency: timers, last-bottle banners and free gifts.
Trimoryn prints an amount for every line and no blend, which is better on one point. It still has soft claims, no study of the product and no named maker, so keep the checks above in mind.
Check04
How can you check a product?
Search the FDA's tainted-product notices by the product name, read the label and ask a pharmacist.
The FDA lists weight loss products with hidden ingredients and notifies the public of ones it finds 1. A missing notice does not prove a product is clean, because the agency tests only some products. A pharmacist can look at the whole label and your medicines, and can spot ingredients that do not belong. Also buy from sources that identify the maker, and keep the order email in case of a recall.

See packsThe rule05
What is the rule for supplements before sale?
The FDA does not approve dietary supplements for safety and effectiveness before they are sold 7.
Firms are responsible for the safety and labeling of their products, and the FDA acts afterward if problems appear 8. That is why hidden drugs can reach shelves. It is also why you should never read the words FDA registered facility as FDA approval. See the quality page.
If unwell06
What should you do if you feel unwell?
Stop the product, call a clinician and, if you have chest pain, trouble breathing or fainting, call 911.

Sources: case report 9, NCCIH on cassia cinnamon 10, MSK on alpha lipoic acid 11, and FDA on sibutramine 3. This list is not complete, and a supplement is never a reason to wait.
