Advantra Z Review - Does This Weight-Loss Ingredient Really Work? Are adverse effects and user complaints deal breakers?

Advantra Z Review

This review is what happened after I obsessed for weeks over Advantra Z. We at DietSpotlight took the time to really investigate, examining the ingredients, side effects, clinical studies and level of customer service. We additionally sorted through countless dieter comments posted on the internet. Lastly, we summarized and condensed the data we collected to give you the important facts you need.


What You Need To Know

First off, Advantra Z is a patented weight-loss ingredient that is made by Nutratech Inc. This substance is also known as citrus aurantium, bitter orange or synephrine. It is a key ingredient in numerous products that are available over-the-counter. It is intended to help increase the breakdown of fat cells and boost thermogenesis. It actually mimics the effects of ephedra, which is a banned weight-loss ingredient.

From what we can tell, Advantra Z has been around since the 1990s. This ingredient is natural and there are some positive comments posted online. Also, the supplements are pretty easy to come by, but read on…

Adverse Effects – “Is This Ingredient Safe?”

The first concern we had was with Advantra Z side effects. “Some people have complained of nausea, headache, heart palpitations, jitteriness and high blood pressure after taking it,” says our Research Editor.

According to WebMD, “Bitter orange, particularly when taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for high blood pressure, fainting, heart attack, stroke, and other severe side effects.”

One customer commented, “This stuff is not safe! Makes my heart pound like crazy!”

User Complaints – “Not a Positive”

We also noticed quite a few customer complaints posted online for Advantra Z products. One person revealed, “Way too many side effects from this stuff. No thanks. It’s not worth it.”

“My doctor told me this product is not safe, so I can’t really use it for weight-loss,” said another individual.

Our extensive research has revealed that if there is a certain aspect of a weight-loss pill or diet program that is very troublesome (adverse reactions, user complaints, unpleasant taste) the real probability of lasting results is low. So, if Advantra Z does in fact cause side effects in a number of people, this could be a big problem.

The Science – “Solid?”

For us at DietSpotlight, we need to see some clinical research that actually supports the product we’re investigating. Fortunately, we did locate some clinical studies that support the effects of Advantra Z in regards to weight-loss. This ingredient does appear to boost thermogenesis, especially when combined with stimulants such as caffeine. However, on the downside, adding the two stimulants together can increase the risk of side effects.

The Bottom Line – Does Advantra Z Work?

So, should you run out and buy Advantra Z? Well, first of all, we like that there are some clinical studies that support this citrus extract for weight-loss. But we have some reservations because it can lead to harsh side effects. Also, we’re concerned about the negative customer comments we found posted online.

If you’d like to drop more weight, then we encourage you to choose a product that does not lead to any harsh side effects, contains clinically proven ingredients for weight-loss and is backed by numerous positive user reviews.

Among the best products we’ve seen in 2016 is one called Leptigen. This product contains a blend of four key ingredients, which have been shown in documented clinical studies to help accelerate fat loss and elevate metabolism. We can’t find any negative comments about harmful side effects and user feedback posted on the web reveals people are seeing excellent results.

The makers of Leptigen are so sure about their product they’re offering a Special Trial Offer, which is a positive sign.

What You Should Know

Advantra Z is a patented ingredient that is present in a number of weight loss supplements. The company that manufactures Advantra Z is Nutretech. One of the major active ingredients in Advantra Z is bitter orange extract, which is also known as Citrus Aurantium. Advantra Z can be found in weight loss products such as Miracle Burn and Nuphedrine. The manufacturers of Advantra Z say that it is the only patented thermogenic ingredient for sale today.


The ingredients in Advantra Z are: Bitter Orange Extract, Protein, Carbohydrate, Omega 3 and 6, Sodium, and Vitamin A and C.

Product Features

Advantra Z is not for sale as a stand alone supplement, so if you want to use it as part of your weight loss program you will have to buy one of the weight loss products for sale which contain this ingredient. Two such products are Miracle Burn and Ephedrine. Both of these products contain Advantra Z, as well as Hoodia Gordonni. Hoodi Gordonni is derived from a cactus that is said to have appetite suppressing qualities and can be found in the South African and Namibian deserts. There is an import ban on products containing Hoodia in Australia, so if you live in Australia you will not be able to order Hoodia-based weight loss supplements like Miracle Burn or Nuphedrine.

The manufacturers of Advantra Z say that it is a safe alternative to the now-banned Ephedrine, which was previously present in a number of thermogenic weight loss products. However, a number of dieticians have mixed feelings about Bitter Orange Extract, which is one of the major ingredients in Advantra Z. They say that the chemical components in Bitter Orange Extract, namely Synephrine and Octapamine, can lead to problems with high blood pressure and heart complications. It would seem advisable, therefore, that anyone with pre existing blood pressure or heart problems should not take Advantra Z.

There are testimonials available online for both Miracle Burn and Nuphedrine, which are both products that feature Advantra Z as a key active ingredient. Some say these products have helped them lose weight, while others say that they have had to stop taking it due to side effects such as headaches, dizziness and shakiness. Of course, it is unclear whether Advantra Z was the ingredient responsible for the negative health complications that resulted from taking these weight loss supplements.

At the end of the day there do seem to be some safety concerns regarding Advantra Z, and therefore we would prefer not to recommend products such as Miracle Burn or Nuphedrine which contain this component. Once we have seen the results of controlled standardized tests relating to the safety and to effectiveness of Advantra Z as an ingredient, we'll begin to consider it. Often, when a new "miracle" ingredient makes its debut in weight loss supplement formulas, we like to wait several years to see if what kind of long-term effects (positive and negative) this ingredient has.
