Absolute Fuel Review - 6 Things You Need to Know


In the weeks that led to this review, I figured out whether Absolute Fuel actually works. We at DietSpotlight conducted a thorough investigation, focusing closely on the ingredients, side effects, customer service and scientific studies. We also looked at countless user comments from around the web. Finally, we summed up all of the facts and feedback we found in order to give you the bottom line.

What is Absolute Fuel?

First of all, Absolute Fuel is boasted as a high energy fat burner for women and men. Put simply, this diet supplement is supposed to help support natural weight-loss, suppress appetite, enhance mood and increase energy levels. It contains chromium, cordyceps sinensis, white willow bark, cinnamon, citrus aurantium, hoodia gordonii, theobromine, taurine, caffeine anhydrous, guggulsterone, irvingia gabonensis, alpha lipoic acid and piperine. You simply take two capsules, twice each day. However, it’s not recommended to take this formula in the evenings, because it contains stimulants.

From what we can tell, Absolute Fuel has been on the market since at least 2012. This diet supplement is made by Bio-Science Institute Inc. This company is located in Palm Beach Gardens, FL. Also, there are some positive user comments for this product, posted online, but read on…

Concerning Ingredients – “An Issue?”

One concern we have is with the Absolute Fuel ingredients. “This weight-loss supplement contains both citrus aurantium (bitter orange) and caffeine anhydrous. When combined, these ingredients can lead to adverse effects,” says our Research Editor.

WebMD states, “Bitter orange, particularly when taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for [side effects].”

On the other hand, one user stated, “I did experience a slight headache with this. But, it does give me more energy as well.”

Another posted, “I like this product okay. It’s a good appetite suppressant for me.”

Side Effects – “Something to Consider”

Another drawback is Absolute Fuel side effects. For example, one customer reported, “Gave me a terrible headache. I will never use Absolute Fuel again.”

However, a different user said, “If you combine this with diet and exercise, it helps you slim down. I did not have any bad reactions to Absolute Fuel.”

“I used it for a while. Didn’t really see a ton of difference, but it did make me eat a little less,” revealed another.

According to our research, if there is a certain facet of a weight-loss supplement that is bothersome, like irritating side effects, the chances of lasting results are not very good. So, if Absolute Fuel does in fact cause unwanted reactions in a lot of people, this could be a serious dilemma.

The Science – “Is Any Presented?”

We did not find any clinical studies that pertain directly to Absolute Fuel capsules. However, this supplement does contain some stimulants. Therefore, it may help elevate metabolism and boost energy levels. Just be aware that certain ingredients may lead to adverse reactions. It’s wise to speak with a doctor before taking this formula.

What Users Are Saying

"”I’ve been taking this product for a little over a month know and it is outstanding! I have been able to drop 8 pounds while on it and can definitely notice more tone in my body overall. I did this by taking the pill about a half hour prior to working out and then combining a workout of cardio and then a strength training workout.”"

"”It works ok but is better for a pre-workout than a fat burner. It sometimes makes me feel kinda strange, so I just stick to one a day. The price is pretty low so it’s okay considering what you pay for it.”"

"”It made my heart feel like it was coming through my chest!”"

The Bottom Line – Does Absolute Fuel Work?

So, should you run out and buy Absolute Fuel? Well, we like that this supplement is easy to use anywhere. It’s also good to see that some positive comments are posted online. But we have some reservations about this diet product because it contains a dangerous ingredient blend. Also, we’re concerned about the side effects some users have reported.

If you’d like to get started shedding pounds, then we suggest you go with a product that contains safe ingredients, does not lead to any harsh adverse effects and is backed by solid research.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement contains four key ingredients., which have been clinically tested and are shown to help increase fat loss and spark metabolism. Also, we can’t find any negative user reviews. Furthermore, the comments around the web indicate people are seeing excellent results.

The makers of Dietspotlight Burn are so excited about their product they’re offering a special trial offer, which is very reassuring.

What You Should Know

The name Absolute Fuel immediately caused images of caffeine pills and stimulants, but the picture on the supplement bottle is of a stellar set of abs, thus Abs-olute Fuel. However, the fat burner is packed with every day ingredients with no mention of slimming the dieter’s abs. Had the company chosen to claim the supplement focused on just one part of the body we would have shot that idea down anyway, but we are curious as to why the company chose a picture of a man’s abdominal section when the fat burner is for weight loss or fat loss.

List of Ingredients

  • Cordyceps Sinesis
  • Taurine
  • Caffeine Anhydrous
  • Irvingia Gabonensis
  • Guggulsterones
  • Citrus Aurantium
  • Theobromine
  • White Willow Bark
  • Cinnamon Bark
  • Hoodia Gordonii
  • Piperine
  • Alpha Lipoic Acid
  • Vanadyl Sulfate
  • Chromium Picolinate

Product Features

The ingredient list for Absolute Fuel is not the best we’ve come across, but it certainly has a foothold in weight loss science. There are two ingredients proven to help keep blood glucose levels in check. We’re lucky to find one in most supplements so finding both chromium and vanadyl sulfate is a pleasure. The hoodia added to Absolute Fuel is worthless as clinical studies have dismissed this ingredient as ineffective. Cinnamon bark and piperine are safe ingredients with some clinical support. Cinnamon may naturally boost fat burn and piperine helps all the ingredients in Absolute Fuel absorb more quickly. We wish there were more positive things to say about this fat burner. Synephrine is a dangerous stimulant with side effect comparable to ephedra. We don’t know just how much is added, but any is more than enough to cause increased heart rate and jitters. Caffeine, typically a safe and effective fat burner, is also added to the formula. This should be a positive thing, but the dieter is not told how much caffeine they are consuming with each dose. Too much caffeine can lead to terrible anxiety, shakes and headaches. Nausea and vomiting may also be a problem at extreme doses. Theobromine is another source of caffeine so that’s two sources of caffeine and no indication of total caffeine dose.


  • The ingredient list for Absolute Fuel is published in the product description.
  • We love the addition of two appetite suppressants.


  • Dieters are expected to take a caffeinated supplement without knowing how much caffeine they are taking.
  • Multiple stimulant sources are used in the Absolute Fuel formula.


Absolute Fuel is not a safe fat burner. There is little doubt this product would be effective for some dieters, but the risk of taking a supplement without full knowledge of caffeine dose is a bad idea. There are proven weight loss supplements with safe and effective ingredients available on the market. Choosing a supplement from a company that lists all ingredients, total caffeine dose and testimonials from real dieters like you is a better option.
