Dexaprine Review - Does This All-Day Thermogenic Really Work? Are questionable ingredients and side effects deal breakers?

Dexaprine Review

No joke – over 50% of diet products simply don’t work. So what about Dexaprine? We did some serious research and created a detailed review, examining the side effects, ingredients, scientific studies and customer service quality. We additionally read through tons of dieter responses from around the web. Finally, we summed up and condensed all of the facts and specifics to give you the information you need.

EDITOR'S TIP: Click here to substitute Dexaprine with a proven fat burner such as Leptigen for better results.

What is Dexaprine?

First off, Dexaprine is advertised as an all-day thermogenic fat-burning powerhouse. The ingredients are acacia rigidula extract, citrus aurantium, caffeine anhydrous, green tea, isopropyloctopamine and rauwolfia serpentina. This product is made by IForce Nutrition, which is located in Vista, CA. You only need to take one capsule each day. According to the website, Dexaprine helps minimize hunger pangs, elevate mood, target fat and provide extended energy all day long.

Dexaprine has been available since 2012 and can be used by women and men alike. It’s convenient that this supplement only has to be taken once each day and it can be acquired online for $28.99, but read on…

Questionable Ingredients – “Look Out?”

The first consideration with Dexaprine ingredients is the risk of side effects. According to our Research Editor, “Dexaprine contains synephrine, which is known as a cousin to ephedra. It may cause rapid heartbeat, increased blood pressure or jitters.”

One customer commented, “I took one full capsule today morning on empty stomach and the result was too bad. I had irregular heart race and felt restless.”

“I literally felt like my heart was going to explode any second. My sitting heart race was insanely fast, I was scared to even check my pulse for the fear of panicking and making my pulse go up even more,” said another user.

Side Effects – “Be Careful”

We have noticed a lot of complaints regarding Dexaprine side effects. In fact, one customer complained, “I just felt really horrible and couldn’t stop my heart from racing and felt like puking my brains out.”

Another user said, “This is a totally horrible product. I took it threw up within in an hour. My heart started racing, I got nauseated while I was taking a shower, vomited several times. Made my hands shake and then I broke into a brief sweat took several hours to feel its effects go away.”

The research we’ve done has shown that if there is a certain facet of a fat-burner pill or diet program that is very burdensome (a painful/difficult exercise routine, dangerous ingredients, serious side effects) the probability of extended weight-loss is low. In other words, if Dexaprine does cause adverse reactions in a lot of users, this could be quite problematic.

The Science – “Legitimate?”

While there is a thorough explanation of the ingredients used in Dexaprine provided on the official website, we did not locate any real science. Unfortunately for this company, at DietSpotlight we need to see actual clinical research that supports the product relating to weight-loss. Here we see a big red flag.

The Bottom Line – Does Dexaprine Work?

You want to know if this one is a keeper, right? Some people will appreciate that Dexaprine is boasted as a hardcore fat burner, but you need to keep in mind the negative customer reviews posted online. It’s clear that this supplement contains a potent ingredient blend, but the adverse effects people have experienced are quite frightening. Therefore we have doubts about recommending Dexaprine as a safe weight-loss solution.

Dieters that wish to shed pounds of fat more quickly, we encourage you to try a diet supplement that contains safe ingredients, does not cause adverse effects and is backed by real clinical studies.

Among the best products we’ve seen in 2016 is one called Leptigen. This diet pill contains a proprietary blend of four ingredients, which have been proven in documented clinical studies to help increase fat loss and elevate metabolism. Moreover, we were unable to find any talk of unpleasant side effects and user feedback found online shows people are seeing significant results.

Also, the makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a good sign.

What You Should Know

Dexaprine is an extreme fat burner from iForce Nutrition. The product description reads like most bodybuilding supplement descriptions. There are graphs and big words combined with creative language and a clear push to try the supplement because you've never felt anything like this in your life. THIS is the supplement you've been looking for, according to iForce Nutrition. We agree, if you've been looking for a supplement to increase blood pressure, cause heart palpitations and cause you to feel nauseous due to caffeine overload.

List of Ingredients

  • Citrus Aurantium
  • 1, 3 Dimethylamylamine
  • Caffeine Anhydrous
  • Green Tea Extract
  • 3, 3' Diiodo L Thyronine
  • 3, 5 Diiodo L Thyronine

Product Features

Citrus aurantium is a source of synephrine commonly added to fat burners that once contained ephedra. When ephedra was pulled from the market, synephrine stepped in claiming it could give the dieter all the same positive benefits without the negative side effects. Synephrine has never been proven to have the same benefits as ephedra, but it does carry some of the same side effects. 1, 3 dimethylamylamine is associated with heart palpitations. Simply put, dieters should not take this ingredient unless they have the okay from their doctor. Patients with kidney disease, liver disease, heart disease, diabetes and a huge list of other medical conditions, should not take 1, 3 dimethylamylamine. Caffeine anhydrous is powdered caffeine. It will increase energy and decrease hunger while promoting a healthy metabolism. But, in large quantities caffeine can cause negative symptoms similar to a heart attack. Green tea extract is another proven ingredient. We can't give Dexaprine credit for including green tea because they don't bother to list how much is in the formula. The remaining two ingredients are supposed to support thyroid function and increase fat metabolization. There are some clinical studies supporting these claims, but they are only available in animal studies, particularly mice.

  • Ingredients are listed online.
  • Contains two proven ingredients - green tea and caffeine.


  • Contains dangerous ingredients that may cause negative side effects.
  • Dexaprine is not the safest fat burner.
  • Not safe for dieters with health conditions or those taking prescription medications.


Dexaprine may have a great website with tons of scientific graphs and literature, but that does not change the fact that the ingredient list is not packed with the best ingredients on the market. How much caffeine is in the supplement? How much green tea does the company include? Why is a stimulant included that causes heart palpitations? When a dieter has more questions than answers it's time to choose another supplement.

    Sounds like nobody listened to the bottle when it said take HALF A PILL TO FIND YOUR TOLERANCE. Have taken and works great for me… if half a pill is too much for you then okay, this product is not for you.. but anyone taking a whole pill your first time you were asking for it…

    Hopefully this stops at least one person from making the mistake I did of trying a sample poll of dexadrine xr I got in the mail from a different purchase. I take stimulants and preworkouts and other fat burners all the time and am very tolerant and this pill was a like a punch in the face.I took a pill of dexadrine on an empty stomach in the morning like it said, and a half hour later I literally felt like my heart was going to explode any second. My sitting heart race was insanely fast I was scared to even check my pulse for the fear of panicking and making my pulse go up even more. And the worst part is I didn’t even feel focused at all like caffeine gives me, I just felt really horrible and couldn’t stop my heart from racing and felt like puking my brains out. I took it at nine this morning it is now midnight and I still feel the effects and am still shaky. This is the worst supplement I’ve ever taken, if you read this do not buy or even try this product because you will regret it. I’m healthy and go to the gym six days a week, and I’ve tried almost every supplement on the shelves and I’ve never had this bad of an experience with any product. I wish I could meet the creator of dexadrine and kick him in the balls for making me feel how I felt today. Screw you dexadrine!!!!!!!!!!!!



    Exactly what jrod said. DO NOT TAKE IT
    It’s shit
