Dangerous and Problematic Weight Loss Ingredients
Not all supplement ingredients are created equal. Some are merely ineffective, while others can cause serious health problems. Here's what to watch for.
Outright Dangerous Ingredients
DMAA (1,3-dimethylamylamine): Banned by FDA but still appearing in some products. Linked to heart attacks, strokes, and deaths. Also sold as methylhexaneamine or geranium extract.
DNP (2,4-dinitrophenol): An industrial chemical illegally sold online for weight loss. Has caused numerous deaths. Never take this substance.
Ephedra/Ephedrine: Banned in the US for weight loss products due to heart-related deaths. May still appear in products from overseas.
Sibutramine: A prescription drug removed from market due to cardiovascular risks. Still found in some imported supplements.
Problematic Stimulants
Synephrine (Bitter Orange): Often marketed as an ephedra alternative. Can raise blood pressure and heart rate, especially when combined with caffeine.
High-dose Caffeine: While moderate caffeine is generally safe, some supplements contain 300-500mg+ per serving, risking heart issues and anxiety.
Yohimbine: Can cause anxiety, rapid heart rate, and blood pressure spikes. Particularly risky for those with anxiety disorders or heart conditions.

Raspberry Ketones: Almost no human research; popularity driven by media appearances, not science.
