Dangerous Weight Loss Ingredients

Ma Huang

Also known as ephedra, yellow horse, or yellow astringent this shrubby plant is common in traditional Chinese medicine. The first known reference of Ma Huang‘s medicinal uses dates back to about 100 AD. Ancient uses included including perspiration in order to treat asthma, influenza, and colds. And in recent times, many dietary supplement companies promote it for weight loss.

Although the plant does seem to treat bronchial asthma, recent legal liability questions have arisen from weight loss use. Apparently it Ma Huang has been linked to adverse cardiovascular effects. So basically, if you have heart issues or are prone to any issues related to circulation, you should stay far away from this ingredient. In fact, there are so many better weight loss ingredients you can use, that you can simply cross this one off your list.


Fenproporex is known as the Brazilian Diet Pill, and even has the word ‘amphetamine’ attached to it. Since it was developed in the 60s as a treatment for obesity, researchers soon discovered the many detrimental problems with this drug. Although it’s illegal in the US, many countries around the world still prescribe it for weight loss. And sometimes it’s even combined with benzodiazepines, which include highly addictive tranquilizers.

This stimulant drug has never been approved by the US FDA, because it’s simply not effective and it’s definitely not safe. Just like other stimulants, it affects the central nervous system and suppresses the appetite. However, this is about as far as it goes to help you lose weight. And overtime, it can seriously mess up the dopamine receptors in the brain, leading to chemical addiction. Some other side effects include fever, sweating, digestive issues, headaches, blurred vision, insomnia, shaking, and cardiovascular issues, including sudden death.


Also known as Meridia, this oral anorexiant was prescribed to treat obesity. And it was often touted as a miracle pill for weight loss. However, Sibutramine has been banned due to increased risk of heart attack and stroke. Some other side effects include flu-like symptoms, high blood pressure, shortness of breath, seizure, depression, insomnia, and overall body pain. It really seems like weight loss with Sibutramine simply isn’t worth the risk.

It works by altering neurotransmitters in the brain. But it only works in tangent with a low-calorie diet – that is, if you’re healthy enough to withstand the numerous life-threatening side effects of the pill. Plus, it has so many interactions with other types of medications, that almost anyone who would need a weight loss miracle like this simply isn’t healthy enough to sustain the damage.

Bitter orange/synephrine

Think that natural ingredients are safer than the artificially made alternative? Think again. Bitter orange is a type of plant that is used for many different things – some safer than others. In fact, when applied topically, it can successfully treat fungal infections. However, when bitter orange is taken internally it’s a different story.

This plant is confusing because it’s used to improve the appetite, but it’s also used for weight loss. In fact, it is often combined with stimulants, which creates an unideal concoction of danger. Basically, it increases the risk of high blood pressures, shortness of breath, fainting, stroke, and other very severe side effects – including death.
