Zantrex Black Buying Guide: Just How Hardcore Is This Fat Burner?

Zantrex Black Buying Guide Review and Results:

Editor’s rating:

Zantrex is a well-known brand that makes fat burner supplements, and they offer several different formulas for different preferences and goals. The Zantrex Black is billed as the “hardcore” diet pill in their lineup, and that’s because it doesn’t just help you lose weight. This helps you lose weight fast.

Or at least, that’s what it’s supposed to do. Hopefully there isn’t another scandal like the Snooki-Zantrex lawsuit.

What’s Zantrex Black?

Zantrex Black is a new supplement that’s a bit different from the other color-coded earlier Zantrex formulas. In the product description, you get words like “accelerated rapid release formula”, “high velocity weight loss”, and “extreme energy fast”. You should get the idea right away that it’s all about how quickly you can lose weight with this.

This comes in soft gel capsules, and you’re supposed to take 2 softgels 15 minutes before your main meals. You should only take up to 4 capsules per day (from the time you wake up to the time you sleep), and only up to 6 capsules for any 24-hour period.

You just need to keep in mind, however, that this is a supplement—so you need a low-calorie diet plan plus a high-intensity workout plan so you can really lose weight.


The expert reviews on Zantrex Black range from cautious acceptance to downright hostility. On, the reviewers like the price and the natural ingredients, but they do mention the massive amount of caffeine. Similarly, the review thinks it can help as long as you have realistic expectations, but warns off those who are sensitive to caffeine.

On the other hand, the review says to “avoid it like the plague”. That quote is actually on the title! It questions the validity of all the Zantrex claims on its benefits because of the low dosage and the stained rep of the brand due to the lawsuit. All it is good for, the review says, is to get a quick jolt of energy.


If you do check the customer reviews on (click to see buying options and reviews), it seems like the people who liked it and the people who said it didn’t work are equal in number. It only has an average rating of 3.3 stars.

Check out the comments:

  • Does a decent job of appetite suppressant. Lots of long lasting energy. I haven’t lost any weight, but I got mainly to stop munching on junk at work while staying awake.” Rick E, verified purchase,
  • I take 2 at 9am and have energy throughout the day. Seems to be helping curb my usual cravings.” Shella, verified purchase,
  • I feel absolutely terrible within minutes of taking this product. I’ll be throwing it all away.” Al, verified purchase,

As you can see, that caffeine sure does have a kick.


This contains a half gram of protein, a gram of fat, 30 mg of Niacin, and a 1.16-gram proprietary blend of various well-known weight loss natural extracts. It’s not specified how much of each ingredient you get, but Zantrex has revealed that it contains up to 300 mg of caffeine and similar stimulants—per serving. That’s like the equivalent of 2 cups of coffee at once, and so you may end up taking the equivalent of 4 cups of coffee a day.

What this means is that if you’re a coffee drinker, then you have to stop being one. If you don’t, you’ll OD on caffeine and you won’t be able to sleep properly. If you’re not a coffee drinker, then you may be very sensitive to it and you may experience side effects like the jitters, palpitations, and insomnia. The massive amount of caffeine means that you can’t take more capsules to increase the dosage of the other ingredients.

Where to Buy

This is available at the official Zantrex-3 website and it sells for $39.99 for each bottle of 84 capsules. You have to remember, however, that the bottle is only good for up to 21 days with 4 capsules a day. Still, you can buy one bottle a month automatically and the price goes down to $31.99 which already includes shipping.

It’s also available on, where somehow its price is noticeably lower, last time we checked (click here to see buying options on Amazon). Order 2 bottles and the shipping is even free. However, it’s not exactly sure how many are in stock. So if you’re interested, this is your go-to online retail store.


Despite the low price on Amazon, you have to wonder about so many things when it comes to Zantrex Black. It’s not good that they’ve been hit with a suit. The amount of the caffeine seems too much, while there isn’t much for the other ingredients. There’s a proprietary blend. The low average rating on Amazon is also worrisome.

Taking this is certainly a gamble on so many levels. If you don’t want to gamble with your money and your health, then perhaps you may want a more reputable fat burner that won’t give you the jitters.
