Zantrex Review: Energy & Weight Loss Supplement?

Updated on July 14, 2020

Zantrex is another product in the weight loss market that claims to be a premium weight loss supplement. But its reputation as being more of a stimulant than a weight loss formula precedes it. Also, it seems to have no evidence regarding its ingredients supporting fat burn.

Does it really aid in weight loss or just work as an energy booster? 

We put our teams to work to find out the truth and if it is a safe supplement for you to use. Here’s all you need to know about Zantrex. 


Zantrex Review: Brand Overview

A natural diet supplement, Zantrex claims to aid in weight loss and increases energy. The caffeine-rich ingredients do give the user an energy boost and make them alert. But it doesn’t do much good as a weight loss formula.

The ingredients aren’t very promising for a fat burner supplement. They are not specific to weight loss which makes the Zantrex formula weak. They do not suppress the appetite nor stimulate thermogenesis effectively to burn the fat. 

We believe there are better supplements that you should check out. We have even suggested an alternative below. You can read about it and decide for yourself. 

Zantrex Pros and Cons

As a dietary supplement, Zantrex has been in the market for decades now. We will be reviewing to understand all its potency as a weight loss formula.

Let’s start with the pros and cons:


  • Boosts energy
  • Uses natural ingredients
  • May improve alertness and focus
  • May boost metabolic rates 


  • Contains a high amount of caffeine and stimulants
  • Potential side effects
  • Unlikely to curb appetite
  • Ingredient amount not specified
  • Only 30 days money-back guarantee

What is Zantrex: Is it Legit?

Zantrex is a dietary supplement that helps in weight loss and gives you an energy boost. 

It is manufactured by Zoller Laboratories that is based in Utah, USA. Zoller has been in the market for around two decades now. It is an alternative to ephedra-based diet pills that was banned. 

The supplement formula contains herbs and stimulants. It is to be taken in combination with a healthy diet and workout routine. 

Zantrex offers three capsule supplements out of which we are reviewing Zantrex-3 High energy fat burner. You can check out the other products on their website. 

To avoid any confusion, it is the one that has a red bottle packaging. According to the manufacturer, it is the ultimate thermogenic fat burning pill.

It is suitable to be used by both men and women. It is to be taken as per the recommended dosage. You need to follow a strict diet and workout routine to get maximum benefits. 

Individuals below the age of 18 years are recommended not to use Zantrex. If you are pregnant or nursing your baby, do not take this supplement.

Zantrex Side Effects

Zantrex-3 has some side effects that you should know about before using. Due to the high concentration of stimulants, you may experience:

  • Headache
  • Jitters
  • Irritability
  • Nausea
  • Diarrhea
  • Increased heartbeat
  • Sleeplessness
  • Mood swings

Though the ingredients used are mostly natural, one might be allergic to them. Do check them before making the purchase.

Better Alternative Available?


Despite being around for about two decades now, Zantrex still is under speculations of being a potent weight loss formula. To be honest, you cannot expect a significant loss in weight with it. 

The ingredients used in the Zantrex-3 do not support fat burn as such. Apart from an increase in energy and improved focus, you may not experience any benefits.

The side effects are really serious and make us doubt the supplement. They can disrupt the normal functions of your body. Also, the customer reviews for the product are mixed. But our research made us clear about the supplement.

It has only a 30 days money-back guarantee which, we feel is quite less. It doesn’t give the user enough time to try out the supplement and come to a decision. 

There are other alternatives in the market that you can try out. Personally, we would like to suggest you PhenQ

PhenQ is one of the finest fat burners out there. It is manufactured by Wolfson Berg Ltd, a leading producer of diet supplements. The company has been in the supplement business for over 10 years now. 

With its high-quality ingredients, it is the most recommended weight loss supplement. PhenQ pills are to be taken twice a day with breakfast and noon or whatever time works for you. 

You need to follow a healthy diet and workout routine to get maximum benefits. 

The clinical trials have verified that the addition of a-Lacy in the PhenQ formula supports weight loss and fat burn. It can also help you gain some lean muscle mass for bulking and cuts. 

The study was done in comparison with Placebo where people using PhenQ lost 7% body fat, 3% body weight, and gained 4% lean mass. We picked up these figures from their official website. Check the full review here.


Here are the ingredients of PhenQ that make it an effective weight loss formula:

A-Lacy Reset:

This ingredient suppresses your appetite and reduces your calorie intake. a-lacy Reset supports the effective burning of fat, increases your energy, and helps the body to recover after the workout sessions. It reduces fatigue and elevates your mood. 

Capsimax Powder:  

This is a thermogenic blend consisting of caffeine, piperine, niacin, capsicum, and vitamin B3. It uses thermogenesis to burn down your body fat effectively. Piperine helps in enhancing the effects of other ingredients in the supplement. 

L Carnitine Fumarate:  

It is a naturally occurring amino acid that is found in red meats, green vegetables, and nuts. It converts the fat into energy so you can burn it out during exercise. Also, it combats the tiredness caused by dieting. 

Chromium Picolinate: 

Chromium is an essential mineral that regulates your sugar and suppresses your carb cravings. When you eat sugar-rich foods, sugar gets absorbed in your body and is further used by the cells to generate energy. Chromium lets you absorb as much sugar as possible so you don’t crave for more. Sugar adds fat in your body and this ingredient prevents it.


Nopal cactus has a high fiber content that controls your hunger. It is rich in amino acids and gives you an energy boost. It flushes fluids from the tissues to your bloodstream through fluid retention. This helps in reducing weight and overcoming flatulence. 


It is a common ingredient in many weight loss supplements. Caffeine acts as a stimulant that keeps you alert and improves focus. Along with reducing tiredness, it also manages your cravings. 

Through the process of thermogenesis, it burns the fat in the body and gives you sufficient energy to workout. 

PhenQ has all the necessary fat burning ingredients that make its formula powerful and effective. All these ingredients are easily absorbed in your body to deliver desired results.

This temperature rise burns down the excess fats and thereby aids in weight loss.

  • Suppresses your appetite: Curbing of appetite is the best way to keep your weight in check. PhenQ has fiber-rich ingredients like Nopal that control your cravings. It makes you fuller so you don’t crave for more food. 
  • Regulates your sugar cravings: Excess sugar increases the concentration of fat in your body. Your blood sugar level needs to be right to lose weight. Chromium Picolinate in PhenQ maintains your blood sugar and keeps your sugar cravings in check.

Side Effects

PhenQ has some minor side effects that you should be aware of. The caffeine in the ingredients might cause the following: 

  • Irritability
  • Jitters
  • Migraine headaches
  • Diarrhea

If you have a pre-existing health condition, speak to your doctor before taking the supplement. Diabetic people should take the supplement only if their doctor approves it. 

Refund Policy

PhenQ has a money-back guarantee of 60 days as compared to Zantrex’s 30 days. They also give your extra one week of return shipping in the guarantee days which makes it a total of 67 days.   

They even take the empty bottles back along with the sealed ones and then refund you for the entire order.

Conclusion: What Should You Choose?


Yes, absolutely. PhenQ is a far better alternative than Zantrex-3. The weak formula of Zantrex makes it an inept weight loss supplement. The side effects are serious and nobody wants to experiment with their body just to lose a few pounds.

Whereas PhenQ has clinically proven ingredients that make it an effective dietary supplement. The customer reviews speak highly of the supplement’s benefits.

You can bid adieu to that excess fat with PhenQ by your side. It takes you one step closer to your desired body goals. If you need to know more about the supplement, you can visit their website
