What Is Zantrex and How It Works to Help You Lose Weight?


Zantrex is an over-the-counter fat burner formula marketed to assist in body sculpting, rapidly and healthily losing weight to people who plan balanced meals and exercise regularly.

This botanical formula heavy on stimulants is also claimed to control appetite, trigger thermogenesis, boost metabolism, provide the energy necessary to stay focused, and consistently endure long strenuous workouts to achieve weight loss goals faster.

Zantrex is also said to initiate lipolysis and help the body release fat cells more efficiently.

Zantrex Ingredients

Citrus Fruit Extract

This active fat burner compound can help your body break down the stored fat for energy more efficiently and feel fuller for longer, enabling you to eat less and enhancing fat loss.

The citrus fruit extract is also rich in flavonoids, which help fight harmful free radicals and bring various other health benefits.

Guarana Fruit Extract

This active energy compound with strong stimulative effects helps increase your energy levels and metabolic rate, improving your focus, keeping you alert, helping overcome fatigue, and burning calories critical for losing weight.

Besides caffeine and other stimulants, Guarana extract contains alkaloids theobromine and theophylline that may suppress appetite, too.

Coffee Bean Extract

Coffee beans extract is another natural source of caffeine commonly found in fat burners, which works as an energy booster.

Moreover, coffee bean extract also contains chlorogenic acid studies have shown to reduce the absorption of carbohydrates, promoting more rapid weight loss [1].

Kola Seed Extract

Kola is a plant from the cocoa family usually grown in Africa, Central and South America.

Kola seed extract contains large amounts of caffeine typically used in fat burners to assist in reducing hunger, providing an energy kick and mental alertness [2].

It is also believed to stimulate the production of gastric acid, improving digestion and even fat oxidation.

Green Tea Leaf Extract

Green tea extract, a common ingredient in many supplements for losing weight, is rich in Epigallocatechin Gallate (EGCG) and other catechins (polyphenols with strong antioxidative properties).

Besides various health benefits, studies say that these substances, in combination with caffeine and green tea extract, may contribute to weight loss [3].

Paired with the guarana extract and other natural ingredients blended in this formula, the unfermented green tea leaf may also work as an appetite suppressant and fat burner stimulating thermogenesis.

It may assist in shedding excess fat by raising your body temperature and providing sufficient energy levels, increasing your body’s efficiency at exercising harder, and burning additional calories even at rest.

Kelp Powder

Kelp is a seaweed that grows on cold ocean floors and provides Iodine and many other beneficial minerals and vitamins that may support your vigorous weight loss exercise regime and enhance post-workout body healing.

This natural fiber might also slow down body fat absorption.

Fennel Seed Powder

Fennel seeds also contain plenty of minerals and vitamins with powerful antioxidant effects necessary to help replenish the lost energy after physical and mental stress [4] [5].

Besides reducing oxidative stress, anti-inflammatory, anti-cancer properties, and mental and heart health benefits, fennel essential oil anethole might help suppress appetite, but the scientific evidence is conflicting.

Alpha Lipoic Acid

Another type of naturally occurring compounds this formula contains is Alpha Lipoic Acid. It’s rich in antioxidants critical for maintaining overall health, especially fighting free radical damage and enhancing the conversion of carbs into energy [6].

This compound is commonly found in brewer’s yeast, spinach, broccoli, peas, Brussels sprouts, tomatoes, and many other veggies.

Zantrex Shortfalls: Possible Side Effects

Some customers have complained of side effects from Zantrex ingredients they noticed while using these weight loss pills.

Potential side effects you can expect the stimulants in Zantrex pills to cause may include

headaches, nausea, abdominal discomfort and pain, jitteriness, rapid heartbeat, irritability, and difficulty sleeping.

This fat burner isn’t suitable for minors, pregnant or breastfeeding women, vegans, or vegetarians.

My Experience With Zantrex

While testing the Zantrex weight loss pill, besides a sudden energy rush, I felt restless and had insomnia (due to its harsh stimulative effect).

My appetite seemed slightly reduced, but I didn’t lose weight, probably because I didn’t use it long enough.

Where Can You Buy Zantrex Weight Loss Supplements?


Similar to many other Zantrex alternatives, you can buy this weight loss supplement from various retailers across the country or online.

However, to make a secure, confident purchase for the best price, it’s always advisable to get any dietary supplements or similar products directly from the manufacturer’s official website.

In such a case, the Zantrex fat burner comes with a 30-day money-back guarantee.

If you’re not satisfied with the product, just send a valid proof of purchase, and the manufacturer promises you a prompt, hassle-free refund (excluding shipping and handling costs).

Zantrex Customer Reviews

Our unbiased Zantrex review would be incomplete if we didn’t check many other online user reviews before making a final judgment on the effectiveness and safety of this fat-burning product.

In short, the experiences of Zantrex buyers are rather mixed, with seemingly more disappointed than satisfied customers.

Some consumers stated that it helped them diminish hunger cravings and gave them an almost immediate energy boost, whereas others said they didn’t lose weight despite feeling more energized.

Some people consider it a waste of money and just another pill making false promises, claiming they didn’t feel the product made any difference, positive or negative.

Some users even claimed that this supplement didn’t reduce their appetite and help them lose weight but made them gain weight.

There were also consumers who lost a few pounds but complained of experiencing headaches, nausea, dizziness, and some harsh adverse reactions.


How Should I Take Zantrex?

You should take Zantrex according to the manufacturer’s directions for use - two capsules in the morning and two more capsules with your main meal with a full glass of water.

Sensitive people should start with one pill before two main meals to test their tolerance to stimulants.

Make sure you take this fat burner in combination with a healthy diet and a strict exercise program for maximized fat loss benefits.

What Is The Maximum Daily Amount of Zantrex I Can Take?

The maximum amount of Zantrex you can take in a day is four capsules within 24 hours. The manufacturer strongly advises users to avoid exceeding this maximum recommended daily dosage.

Does Zantrex Interact With Other Medicines?

Since it’s loaded with potent stimulants, Zantrex can interact with other prescription and over-the-counter medicines, so you’d better speak to a healthcare provider before you start using it to avoid any risks.

Can I Still Consume Caffeine While Using Zantrex?

Even though you can still consume caffeine while using Zantrex, the manufacturer strongly suggests that you limit your caffeine intake to minimize the risk of adverse effects because this fat burner supplement already contains large amounts of it and other stimulants.

Is Zantrex Dangerous?

If used strictly as directed, Zantrex should be safe for most healthy adults. Still, individuals sensitive to stimulants may experience some side effects.

People with pre-existing medical conditions, taking medications, pregnant or nursing women shouldn’t use it.

Which Is the Best Zantrex for Weight Loss?

Zantrex-3 High Energy Fat Burner is the best suited Zantrex diet pill for weight loss.

Does Zantrex Really Work for Weight Loss?

Zantrex might help individuals who already eat healthily and exercise regularly, but it’s very unlikely to work without a vigorous diet and exercise routine.

If you’d rather play it safe and opt for a widely approved fat burner with high-quality, all-natural ingredients in transparent dosages backed by clinical studies, manufactured by a renowned company, and covered by a 60-day refund guarantee, I’d suggest trying PhenQ instead.

Not only does it burn stored body fat, curb hunger, improve mood, and boost energy, but it contains ingredients that prevent new adipose tissue formation.

Order yours today, and see for yourself why numerous glowing user reviews also speak in its favor.

Is It Really Effective For Weight Loss?

  1. PhenQ has always been my first choice, but Zantrex Red sounds promising!

  2. Zantrex Red is the best weight loss supplement I have ever tried. I have tried many of them before but none have worked as well as Zantrex. The capsules are easy to swallow and it’s not hard on my stomach at all. The price point is way better than most other supplements on the market too which made me switch to this brand.
