Phentermine versus Proactol diet pills

Which diet pill is safer in the long run?

The number of weight loss aids that appear on the market almost every day is huge. Out of all these products only a small number of them will have some kind of medical approval in the form of medical studies or doctors endorsing the products.

Phentermine is probably one of the most popular weight loss drugs that ever existed. Manufactured in 1959, Phentermine is prescription only weight loss aid that has helped many individuals in the past. That's why we wanted to dig deeper and compare Phentermine side by side to Proactol diet pill and see which one is better and why.

What is Proactol Plus?

Originally known as Proactol, this natural fat binder contains 100% herbal ingredient called NeOpuntia, proven to contain excellent fat binding properties.

When NeOpuntia comes into contact with dietary fats in your stomach, it binds to them and makes them too big to be digested by your system. Those fats that can't be absorbed have to be eliminated via natural processes (bowel movements).

It is said that Proactol can bind about 28% of the fats from your diet. Besides fat binding, Proactol is believed to also help you suppress your appetite and may lower blood cholesterol levels in certain individuals. No side effects have been reported by consumers.

What is Phentermine?

Phentermine is powerful synthetic drug that directly influences workings of your nervous system. It makes your brain release large amounts of neurotransmitter norepinephrine, which puts your body into "fight or flight" mode. One of the consequences of this process is suppression of appetite.

We have to say that we were impressed by results that some people had with Phentermine but at the same time we were shocked to learn how this drug worked. And this need to be understood by more people – Phentermine is a drug; it is not a supplement. Structurally it is very similar to Amphetamines.

Side effects - main problem of Phentermine

Dig deeper into Phentermine substance and you will discover that besides losing weight, many people have reported side effects, from mild to more serious: fast heart rate, high anxiety levels, irritability, dry mouth, fatigue, diarrhea, and constipation. Some of the more serious side effects that can arise are: being hostile and aggressive towards others, seizures, fever, mania, hallucinations, mood swings, being hyperactive etc.

Another interesting fact: in 1997 a diet pill called Fen-Phen (contained Phentermine as its main ingredient) was shown to be the main cause in 24 cases of heart valve disease reported by users. Soon after Fen-Phen was removed from the market and Phentermine became controlled substance. Today you can only get Phentermine with prescription.

Our rating

Proactol – our preferred choice

When we put Phentermine and Proactol side by side, the obvious choice for us was Proactol.

One of the main advantages of Proactol is the fact that it doesn't cause any side effects, compared to the numerous side effects of Phentermine.

Another convenient benefit is that you can take Proactol for as long as you want. With Phentermine you can take it only for up to 12 weeks and under close supervision of your doctor. However, Proactol doesn't have shelf life and is completely safe for long-term use.


While Phentermine really can be very effective, there are many more negative sides than positive ones. We simply cannot ignore all the possible side effects and risks that this drug carries with it. Also with Phentermine people can easily get addicted so that they need these pills just to feel normal. Proactol is the obvious winner here!
