This review is what happened after I obsessed for weeks over Advantra Z. We put the spotlight on side effects, ingredients, and clinical studies. We took in hundreds of dieter comments and reviews. Then, we summarized and condensed the info to give you the facts you need.
What is Advantra Z?
First off, Advantra Z is a stimulant derived from the bitter orange plant. There are hundreds of supplement lines that sell this brand-name synephrine or citrus aurantium. The ingredients vary by brand but may include p-synephrine, n-methyltyramine, hordenine, octopamine and tyramine. It promotes weight-loss by increasing the breakdown of fat cells and boosting thermogenesis. You can find it listed as an ingredient in over-the-counter dietary supplements. 
Advantra Z was touted as the “next generation ingredient” when it was introduced in 1996 by Nutritech. It’s sold through supplement stores and at local retailers. We like that it’s easy to locate and that we found some positive customer comments, but read on…
Adverse Effects – “Safety First”
The first concern we had was with Advantra Z side effects. “The ingredients in this one act similar to several stimulants on the market,” said our Research Editor. “Some people have complained of nausea, headache, heart palpitations, jitteriness and high blood pressure after taking it.” 
According to WebMD, “When taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for high blood pressure, fainting, and other severe side effects.” 
One customer commented, “This stuff is not safe! Makes my heart pound like crazy!”
We found some users that didn’t notice negative side effects while using Advantra Z. 
“No headaches, anxiety or irritability,” commented a dieter.
Advantra Z User Complaints – “Not a Positive”
The comments posted about Advantra Z weren’t always positive. One person said, “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.
On the other hand, some users shared their positive experiences using it. “It gives me the boost I need in the morning. I remember not to drink any coffee though,” reported a customer. 
“It’s cheap and effective. That’s all I care about,” stated another.
Our extensive research has revealed that if there is a certain aspect of a weight-loss pill that’s concerning, like negative customer comments, long-term success could be reduced. If customers aren’t happy after using Advantra Z, there’s a problem.
The Science – “Solid?”
For us at DietSpotlight, we need to see some clinical research that 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, we like that there are some clinical studies connecting the herb to weight-loss, but we’re concerned about this one because the same research shows it causes harmful side effects. We’re also a bit skeptical about it because of the negative customer comments and reviews posted online.
If you’d like to drop more weight, then we suggest going with a supplement not connected to harmful side effects, contains clinically proven ingredients promoting weight-loss and is backed by positive user reviews.
Among the best products we’ve seen this year is one called Dietspotlight Burn. This product promotes weight-loss by offering a blend of four key ingredients, which have been shown to help accelerate fat loss and elevate metabolism. We can’t find any comments about harmful side effects and user feedback reveals people see excellent results.
The makers of Dietspotlight Burn are so confident about their product; they’re offering a special trial offer, which is a positive sign.

What You Should Know About Advantra Z
Advantra Z is a patented ingredient that is present in some 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 of Advantra Z
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 some thermogenic weight loss products. However, some 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.
Advantages of Advantra Z
- Products containing Advantra Z are available for sale on line
- There are testimonials available written by those who have already tried various products containing Advantra Z.
- There is an ingredient list available for Advantra Z.
Disadvantages of Advantra Z
- There have been some reported side effects related to products containing Advantra Z.
- Advantra Z cannot be purchased as a stand-alone supplement.
- Those with heart or blood pressure problems should not take products containing Advantra Z.
- There have been no controlled standardized tests carried out that we could find focusing on products containing Advantra Z.
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 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.
