However, in this article, we are going to focus on Xenadrine Core, which is a very popular product used by dieters and bodybuilders. Xenadrine Core claims to be a powerful weight loss dietary supplement that uses a hardcore thermogenic formula to burn down your fats and transform them into energy. It claims to bring unrivaled sensory and energy to your body, which, in turn, allow you to exercise more effectively, further enhancing your weight loss and bodybuilding progress.

You should start with just one capsule per day; you can start taking two capsules per day on the third day since the start of your diet.

On the other hand, Zantrex 3 is also a weight loss dietary supplement that has recently become trending. It is one of the most popular products from the Zantrex brand. It is coming with quite a bold claim. It says that it brings 546% more weight loss than the leading ephedra-based diet pill. It claims to give rapid weight loss and extreme energy to the user. A serving equals to two capsules, but you can choose to take just one if you think two capsules are too much for you. Take a serving 15 minutes before every main meal, but you should not exceed six capsules per day.

Xenadrine vs. Zantrex 3: What Are The Ingredients?

Xenadrine Core is packed with the Xenadrine NeuroAMP Blend, which contains green coffee bean extract, caffeine anhydrous, L-theanine, yohimbe bark extract, perilla seed extract, caraway seed extract, coleus root extract, gotu kola extract, white kidney bean seed extract, and mangosten pericarp powder. Of course, it contains caffeine. The total amount of caffeine in the product is approximately 150 mg. Caffeine is a well-known substance that has been scientifically proven to induce weight loss by becoming a thermogenic agent. Caffeine causes the body to burn fats more quickly, thus producing more energy. Caffeine also increases your mental alertness and wakefulness. The other ingredients have been used in many other weight loss products, too, though their effectiveness is seemingly not as great as caffeine.


On the other hand, Zantrex 3 is armed with a proprietary blend, featuring various extracts, such as yerba mate, guarana seed, trimethylxanthine, damiana leaf, green tea, kola seed, schizonepeta, rhodiola crenulata root, black pepper, Asian ginseng, maca root, cacao seed, and black tea. It also contains 30 mg niacin a.k.a. vitamin B3, which is beneficial for reducing bad LDL cholesterol and triglycerides levels in the body and increasing good HDL cholesterol level. A serving (two capsules) of Zantrex 3 contains approximately 300 mg of caffeine.

Xenadrine vs. Zantrex 3: How Effective Are They?

You can already forecast their effectiveness based on the caffeine amounts. Generally, such weight loss products rely primarily on caffeine for the results. With a lower amount of caffeine, Xenadrine may give slower, less drastic results. Some users have reported that Xenadrine takes about a full year before it shows any noticeable result. Due to the slow effect, some people have thought that it is not effective and thus stopped using it. Still, if you consume it regularly and exercise properly, you can expect good results after some time.

On the other hand, Zantrex 3 has been praised by many people because the effects it brings are indeed more immediate. After starting consuming it, you will full faster, and you will notice significantly increased energy. Thus, Zantrex 3 can be used a pre-workout supplement as well. You can expect results within two weeks.

Xenadrine vs. Zantrex 3: What Are The Side Effects?

We should note that a more potent drug usually would have more severe side effects. Xenadrine, with the smaller amount of caffeine, has less adverse side effects. Many people don’t get noticeable side effects from it, but there are also some reports about dizziness, irritability, and jitteriness, all of which are related to the caffeine content.

Zantrex 3

Zantrex 3 seems to cause more intense side effects on some people, especially those who are not tolerant to caffeine. The side effects may include dizziness, irritability, jitteriness, nausea, and rapid heartbeat. You should not take both Xenadrine and Zantrex 3 when you are going to sleep within a few hours because they will make it difficult for you to sleep. You should know that the caffeine limit for most people is about 400 mg, which is roughly equal to four cups of brewed coffee. Zantrex 3 can bring you pass the limit more easily if you also consume other caffeinated beverages such as coffee and energy drinks, and you simply pass the limit if you take more than two capsules in a day.


If you really need to cut down your weight loss within a short period of time, Zantrex 3 is your best bet. It has a more potent formula that can quickly reduce your body weight. However, if you do choose Zantrex 3, be careful not to exceed the daily caffeine limit, especially if your body does not tolerate caffeine well. It can bring significant side effects such as dizziness, irritability, rapid heartbeat, and nausea. If you are not in a hurry, Xenadrine Core would be a relatively safer and healthier solution. Xenadrine Core takes more time, but is also effective given the time and commitment.
