Zantrex 3 Review: Does This Natural Fat Burner Work? My Results!

by Joe Costello, CNC | Men's Fat Burners

Zantrex 3 Fat Burner Zantrex 3 is perhaps one of the most overrated at burners on the market today. It’s popular because it is available in GNC stores, but the truth is it has a weak supplement facts panel and lacks potency in my opinion as a Nutrition Coach. Plus, I personally tried Zantrex, and it did nothing for me whatsoever.

Read this Zantrex 3 review to learn why we do not recommend this fat burner. By the way, there are plenty of other fat burners that we strongly recommend. To discover the best ones, go to our Top 10 Best Natural Fat Burners page. I’ll also talk about my favorite one below!

Zantrex Review by a NASM-Certified Nutrition Coach: Does It Work?

This is an easy one for me. It’s part of my job to be able to look at the supplement facts panel of any given product and be able to give an opinion on it. The other day, I was at my local GNC, and I’ll be honest…I took one look at the Zantrex 3 nutrition facts and almost laughed out loud. This fat burner is just a 1300 milligram proprietary blend. That’s a very low overall potency when you compare it next to the top shelf fat burners…BUT, I bought the product anyways to test it out for you guys, and here’s what happened…

My Zantrex 3 Results And Personal Experience

I’m fully aware I already said some negative things about Zantrex 3 based on my analysis of the nutrition facts, but as a Nutrition Coach, I always feel obligated to personally test the supplements I review. I just don’t feel comfortable recommending or not recommending a particular supplement unless I have personal experience with it, especially if it’a s super popular product like Zantrex 3. So, I went to GNC, bought a bottle, and took it for 30 days…

In my experience with Zantrex 3, I noticed a grand total of one benefit: an energy boost. It doesn’t take a rocket science to figure out why a person might get an energy boost from this product…the second highest dosed ingredient is caffeine. So basically, Zantrex is just a super overpriced cup of coffee. An energy boost is great, but I expect a heck of a lot more benefits from fat burner. If all I wanted was an energy boost, I’d drink some coffee for 1/40th of the price.

The energy boost did help me out in the gym in terms of my endurance and strength, but again, that’s just not enough of a benefit for the supplement to be worth the money. When I buy fat burner, I’m looking for it to help me burn fat…my end goal is weight loss, and that is NOT what I got with Zantrex 3. I didn’t lose a single pound after 30 days of taking it…yikes.

Bottom Line: Based on the combination of my analysis of the supplement facts as well as my very negative personal results (or lack thereof) with Zantrex 3, I would never recommend this product to anyone.

What Is Zantrex 3?

Zantrex 3 is a fat burner that has recently been receiving significant attention. Our job is to analyze this product and determine whether or not it deserves all of the attention its been getting, and we hope this fact-based Zantrex 3 review accomplishes this.

Every time a product becomes popular, it is our objective to help you decide whether or not that product is popular for good reason. In other words, is Zantrex 3 truly an effective fat burner, or a dud? Read on to find out the answer to this question and learn exactly why we didn’t rank it on our list of the top 10 best natural fat burners.

How Does Zantrex 3 Work?

In general, fat burners are formulated using natural ingredients that have the ability to put your body into a “fat burning state” and deplete your fat stores. The truly effective ones are able to do exactly that and much more.

The idea is to find a fat burner that not only has the ability to eliminate the fat stores you already have built up, but also prevent you from gaining any more fat (this is what we call putting your body into a fat burning state).

The top-notch fat burners will do this by containing not only fat burning ingredients, but also ingredients that have the ability to boost your metabolism and put your body into a thermogenic state (great for burning fat).

However, we do not believe Zantrex 3 has the ability to accomplish these things…at least not as effectively as our top ranked fat burner. Check out Instant Knockout under our Fat Burners Section.

We have determined both of these products to be top-notch, highly effective, and last but not least, relatively inexpensive. Read their reviews or watch the review videos on their respective pages to find out what makes them two of the best fat burners on the market.

With all that said, we don’t simply want to tell you, “No, it doesn’t work” and leave you without an explanation. That’s not what we do. The following section analyzes the quality and amounts of the ingredients in Zantrex 3 in order to explain exactly why we don’t believe it to be among the elite in terms of fat burners.

Zantrex 3 Ingredients and Supplement Facts

Zantrex 3 Ingredients

What makes a supplement effective or ineffective? It’s simple…the ingredients. When a supplement contains the right ingredients, you can be sure it’s going to work. When a supplement contains sufficient amounts of the right ingredients, that’s when it becomes top notch.

The problem is that most people don’t know what the “right ingredients” are, and that’s what we are here for. The following section takes an in depth look at the Zantrex 3 supplement facts.

The primary issue we have with this fat burner is its use of a proprietary blend. As I said before, supplements are top notch when they contain sufficient amounts of the right ingredients. The use of a proprietary blend allows the manufacturer to leave the amounts of the ingredients undisclosed.

If you are unable to see the amounts of each ingredient, how can you know for sure whether the supplement is effective or not? The answer is you can’t, and that is our primary issue with this product. With that said, we can still go over each of the primary ingredients.

Zantrex 3 contains yerba mate, guarana, damiana, trimethylxanthine (essentially caffeine), and guarana extract. These ingredients are for the most part very effective and are considered by most experts to be great fat burning ingredients. So what’s the problem?

Well, as said before, we don’t know if there is enough of each ingredient for the product to actually be effective. There must be a certain amount for the ingredient to truly work, and we are unable to tell whether there is enough.

In addition, there are several other more effective fat burning ingredients that could have been included and would have made this a better supplement. Overall though, it is a good supplement.

Zantrex 3 Blue Bottle Vs. Red Bottle – Is One Better Than The Other?

We aren’t going to bore you with the details, but to simplify a complicated explanation, the blue bottle is better overall. While we wouldn’t necessarily recommend either of these products, the blue one is going to be more effective than the red one.

We have observed several reviews based on customer’s personal use, and have determined that the blue bottle produces better results and causes less side effects than the red bottle. Check out the following sections for more details.

Other Zantrex 3 Fat Burner Reviews – The Blue Bottle

Based on the reviews we read from people who have personally used the product, it does provide a significant increase in energy levels. It also appears to be effective in reducing cravings and appetite. Several users reported minor weight loss in their reviews.

Overall, the reviews were fairly positive with the exception of some side effects that were reported. It is worth noting as well that these side effects were reportedly much worse for users who tried the red bottle (this is one of the reasons we recommend the blue bottle over the red bottle). Check out the next section to learn more about Zantrex 3 side effects.

Zantrex 3 Side Effects

There were a significant amount of side effects reported for both the blue bottle and the red bottle of Zantrex 3. However, the red bottle appears to have much worse side effects than the blue bottle.

If you are still considering Zantrex 3, hopefully at this point you have decided against the red bottle. We will go ahead and elaborate on only the blue bottle since it is the better of the two.

According to people who tried the product, side effects for the Zantrex 3 blue bottle include but are not limited to the following: insomnia, dizziness, nausea, dizziness, vomiting, and problems with appetite. Obviously you’re going to want to avoid these side effects, which is why we have provided you with our recommendation at the bottom of this page.

The Pros

  • Users seem to have experienced results
  • The product has recently become fairly popular
  • Zantrex 3 is pretty inexpensive
  • It contains some proven fat burning ingredients

The Cons

  • It appears to cause some unwanted side effects
  • The product uses a proprietary blend
  • Zantrex 3 did not make our top 5 fat burners

Zantrex 3 Conclusion & Our Recommendation

Overall, Zantrex 3 appears to be a fairly average fat burner. Based on the reviews we read, it produces results, but also produces some side effects. Our main issue with the product is the use of a proprietary blend, as well as my very negative personal experience with it.

When all is said and done, this is not a bad product, but we simply would not feel comfortable recommending it. Our recommendation for those in search of a fat burner is Prime Shred. After analyzing more fat burners than you can imagine, we determined this to be the absolute best fat burner on the market.
