Zantrex Red Review: Does it REALLY Work?


  • Contains some ingredients that are effective for weight loss (e.g. Green Tea Extract)
  • Can help boost your energy levels


  • A bit overpriced – $39.99 on the official website for a jar with 2-week supply
  • Uses a proprietary blend
  • Lacks some of the core ingredients for weight loss

Zantrex Red Review at a Glance: Zantrex Red is a dietary supplement that comes in a form of capsules, with 56 capsules per container. That is enough to provide you with a 2-week supply. Considering that, they’re a bit overpriced, starting at $19.99 per jar in Walmart, and $39.99 on the official website. If you want to feel more energized, these capsules use caffeine, which can help you with boosting your energy levels. Zantrex Red also uses 964 mg of a proprietary blend per serving, which means that the exact dosage of all the ingredients included in the blend is unknown. So, the effectiveness of all of these ingredients will remain a mystery until the manufacturer decides to be more transparent! Some of the ingredients are unnecessary and won’t help with fat-burning. We don’t think Zantrex Red will leave you delighted when it comes to weight loss. You might achieve some results in the long run if you’re consistent, alongside a calorie-restricted diet, but that won’t be anything significant. You should skip Zantrex Red if you’re serious about weight loss.

About Zantrex Red

  • Reducing your BMI

Are these all just hopeful claims, or does Zantrex Red really work? Will it help you achieve your weight goals, and burn all that unwanted fat? There’s only one way to find out. We’re going to analyze the ingredients in its formula to see how effective they are when it comes to cutting pounds. We’re also going to check how safe this supplement is. Let’s get into more details!

Zantrex Red Ingredient Analysis

Zantrex Red Ingredients

We don’t like to start on a bad note, but when we first looked at Zantrex Red’s ingredient formula, we immediately noticed that it uses a proprietary blend. That is always a bad sign when it comes to fat-burning supplements. You may wonder, why is that?

A proprietary blend means that all of the ingredients contained in the formula are mixed together in that blend, and you can’t know the exact dosage of each of those ingredients. That means that the effectiveness of each ingredient in the formula will remain unknown. For example, the dosage of some high-quality ingredients for weight loss included in the blend could be as low as 1mg per serving.

There’s 964mg of a proprietary blend per serving in Zantrex Red. Also, the manufacturer stated that there’s about 200mg of caffeine and caffeine-like stimulants per serving in this supplement. Let’s break down all the ingredients included in this blend!

Citrus (fruit) Extract

The manufacturer didn’t provide information on which citrus fruit exactly is being used in the ingredient formula. However, citrus fruits, in general, can have some metabolic boosting effects, but when it comes to weight loss, evidence shows the results aren’t significant.

Guarana (fruit) Extract

Guarana is a fruit common in Brazil. Guarana seeds contain more caffeine than there is in coffee beans. So, this ingredient can help you boost your energy levels. Because of the caffeine, guarana can also boost your metabolism. That means that your body may eventually burn more calories, providing some effects in the long run when it comes to weight loss, when paired with a healthy diet. However, these effects won’t be anything drastic, don’t expect magic with this ingredient when it comes to fat-burning.

Coffee Bean Extract

Green Coffee Bean is an excellent choice. It is an unroasted coffee bean with very little caffeine but more of something that it called Chlorogenic acid. This compound can help improve the digestion of carbohydrates, it can help regulate blood sugar, and even aid weight loss slightly. The dosage of this ingredient is unknown in Zantrex Red, so its true effectiveness is questionable. More on the science behind coffee bean extract can be found here: (

Kola (seed) Extract

Kola extract can help improve your digestion, boost your metabolism and boost your energy levels because of the caffeine content included. When it comes to weight loss, it can help slightly by reducing your appetite. This ingredient is considered unsafe when used in higher doses because it can have an impact on your heart rate and it can cause side effects such as insomnia, nausea, and vomiting. The dosage in Zantrex Red is unknown.

Green Tea (leaf) Extract

Green Tea Extract is a decent ingredient when it comes to weight loss. It contains “catechins” which is a chemical that can make your body burn more calories. It also contains caffeine, which can promote weight loss and suppress your appetite.

Kelp Powder

Kelp is high in antioxidants and minerals such as iodine and zinc that can help with cardiovascular health. When it comes to fat-burning, it isn’t a reliable ingredient.

Fennel (seed) Powder

Some of the benefits of fennel seed powder include: improving digestion, regulating blood pressure, preventing cancer, reducing asthma, bronchitis, and coughs. When it comes to losing pounds, fennel might help because it’s high in fiber, which can make you feel fuller for a longer period of time and reduce your cravings. That way, you might consume fewer calories, leading to some results in the long run. But, don’t think that this particular ingredient will do anything drastic.

Alpha lipoic acid

Alpha-lipoic acid is found in your body, but it can also be found in various foods. This ingredient is an antioxidant that can help protect against cardiovascular diseases and liver diseases. It helps break down carbs and turn glucose into energy. It is moderately effective when used in higher doses (300-700mg) when it comes to weight loss, but it is known to cause negative side effects for a lot of people. ALA is best avoided if you suffer from heavy metal toxicity as improper use can redistribute mercury around your body and make the symptoms worse. When we look at the 964mg of the proprietary blend, it’s easy to conclude that the dosage of alpha-lipoic acid is probably very low in Zantrex Red. And we believe it is for the better!

Our Commentary on Zantrex-3 Red’s Formula

Zantrex Red didn’t blow us away, mostly because of the proprietary blend. It also uses some of the unnecessary ingredients for weight loss, which could have been replaced with some potent ones such as chromium or cayenne pepper extract. This supplement might help you achieve some slight results in the long run if you’re consistent, but we wouldn’t expect anything significant. If you’re serious about losing weight, we recommend searching for a better alternative.

How to Use Zantrex Red

As for the dosage, the manufacturer recommends using 2 capsules of Zantrex-3 Red in the morning, and 2 capsules with the main meal. That is a total of 4 capsules of Zantrex Red per day. Do not exceed the recommended dosage, ever!

Side Effects

As for the side effects, Zantrex Red should be safe for you if you follow the recommended dosage and if you’re a healthy person. However, because of the xanthine mixture it uses (caffeine and stimulants similar to caffeine) of 200mg per serving, side effects such as insomnia, faster heart rate, headaches, or dizziness might occur if you exceed the recommended dosage. These are extremely rare, however. It would be best to consult with your doctor before taking Zantrex Red or any other supplement for the first time. Do not consume these capsules if you’re on medication or if you have a condition.

Testimonials & Reviews

Zantrex Red received mostly positive reviews on Amazon. However, some users weren’t satisfied with the results of this supplement. Here are the comments that they left:

This product gave me horrible headaches. I’ve been taking 1 a day since I received it and I was getting headaches and feeling really exhausted. Stopped taking them today and I’ve been feeling like myself. Probably why they don’t offer a return policy on this product. – Lacey

Have not seen any evidence of weight loss with this product. But I have seen a distinct drop in appetite and improved energy levels with it. Buying again. – Dana

Unfortunately, this did not work for me. I didn’t lose weight and I would not recommend this product. – Amazon Customer

Pricing, Availability, and Other Things to Consider

Zantrex Red is currently not available on Amazon or Walgreens, but you can buy it on the official Zantrex website for the price of $39.99 per jar. It is also available in Walmart for the price of $19.99 per jar, which is way cheaper. When we consider that these capsules would last you for only 2 weeks, we think they’re a bit overpriced.


Zantrex Red hasn’t left an overly positive impression. It uses a proprietary blend which is an immediate red flag when you look at the supplement’s ingredient profile. It uses some decent ingredients for weight loss, but the ingredients’ exact dosage is unknown. It also uses some of the pointless ingredients, which could have been replaced with some that are more effective for fat-burning. You might feel more energized with this supplement because it contains some caffeine, but if weight loss is something you’re going for, there are better products available on sale right now.
