Zantrex Black Overview
Zantrex is a very popular, yet controversial weight loss supplement made by Zoller Labs.
First there was the original Zantrex 3 in the red bottle, which we’ve actually tested.
The side effects of the red bottle were just too much for some, and here’s just a sample of some of them that were left on our site back in 2015.
Then there was Zantrex 3 Blue which was the company’s answer to complaints of side effects caused by original.
The blue bottle is a GREAT fat burner, and is actually one of the best fat burners for women we’ve ever tested.
Now there’s Zantrex Black, the Accelerated Rapid Release Formula.
All three of the products in the line have the same stated goals, which are to:
- Burn fat
- Decrease appetite
- Give you energy
- Help you lose weight
But they each approach it in a different way.
We’ve reviewed Red and Blue in the past.We’ve even compared them.
So this time, we’re primarily dealing with Zantrex Black.

Zantrex Black, as stated above, is the option for people who want a fast acting weight loss supplement that they can use in conjunction with any sensible weight loss product.
The focus is on the quickness of both the initial energy boost, and the weight loss.
So if you’re looking for instant gratification, Zantrex Black is the one to choose.
Zantrex Black Ingredients and How They Work
Of course, the most important factor in whether or not a supplement works is the formula, so let’s get right to it.
Here’s a quick look at the label:
TheZantrex Blackformula includes:
- Niacinwhich increases blood flow.
It’s actually known to sometimes cause a warm “niacin fliush” where your skin gets a little red and tingly from the blood rushing through the blood vessels.
- Protein: I’m not even sure why they included this as an ingredient in Zantrex Black, mainly because it only contains 0.5 grams. This dose is nowhere close to making any sort of reasonable difference.
The Zantrex Black Proprietary Blend which provides several sources of caffeine including:
- Green Tea which also provides fat burning, antioxidant ECGCs which have been shown to burn fat.
- Guarana Seed Extract: Commonly found in many other fat burners like Slim Trim and 1 M.R., Guarana is basically a stimulant that contains chemicals similar to caffeine.
- Yerba Mate Leaf Extract: Another stimulant which is actually rich in antioxidants due to its high concentration of polyphenols.
- Black Tea Leaf Extract
- Kola Seed Extract
- Trimethylxanthine (which is the chemical name for pure caffeine).
And other ingredients including:
- Maca Root Extractwhich increases the release of dopamine from the brain.
This improves mood and motivation to curb emotional eating.
- Asian Ginseng Root which also improves blood flow to supply more nutrients and oxygen to your muscles while working out.
- Damiana Leaf Extract which elevates mood and suppresses appetite.
It may also inhibit the conversion of testosterone to estrogen.
- Schizonepeta Flower Extract which is commonly used for colds and sore throats, but doesn’t seem to have a connection with weight loss that I’ve been able to find.
- Black Pepperwhich helps increase thermogenic activity in the body.
- Rhodiola Crenulata Root Extract which relieves anxiety and helps burn fat.
- Cacao Seed Extract which can reduce the production of fat cells.
Clearly, the formula is very caffeine heavy, but because it’s all couched within a proprietary blend, we don’t know any real numbers or actual amounts.
The whole blend totals 1,160 mg, and about half the ingredients are basically caffeine, but since they don’t reveal the amounts, we don’t know how much caffeine they’re putting in Zantrex Black.
Given that this is a Zantrex product, famous for being pretty speedy, my guess is it’s a lot.
How To Take Zantrex Black
The recommended dose is 2 softgels taken about 15 minutes before main meals.
You can take 1 or 2 as needed for energy, but it is not recommended that you take more than 6 in one day.
There is also a recommendation that you avoid additional caffeine when taking Zantrex Black.
I would also add another caution against taking Zantrex Blacktoo close to bedtime.
I would imagine it would interfere with a good night’s sleep.
Zantrex Black Reviews
Next to the formula, which we now know is extremely stimulant-heavy, the second most important factor in determining whether or not Zantrex Black is any good is what kind of feedback it gets from actual customers.
We’ve actually had about 40 people leave reviews of Zantrex Black on our site.
On the one had you have the positive experiences, like this one:
And this one:
And on the other hand, you have the NEGATIVE experiences that some have encountered:
And this one:
The positive Zantrex Black reviews outweigh the negative ones at about a 10:1 ratio, but I mean come on…
We’re not talking about people just saying things like:
- It didn’t work for me
- I didn’t feel any effects
- Doesn’t work
Instead we’re seeing things about blood pressure skyrocketing and near death experiences.
Since Zantrex Black is sold at Amazon.com, there are dozens of reviews to look at, and the opinions are widely varied when compared to the reviews on our site.
There are almost as many 1-star reviews as there are 5-star ones.
First here are a couple of the raves, all from verified purchases:
And here’s some of the feedback from unhappy customers:
As mentioned earlier, we actually have about40 customer reviews posted below, and the vast majority reflect those on Amazon.
Something important to make note of in the reviews is that even people that like Zantrex Black mention the side effects.
It’s mainly a matter of degree of tolerability that determines whether or not the reviews are good or bad.
There seems to be little question that Zantrex Black can increase your energy, and that’s the primary benefit users talk about.
But for some, the side effects are too much.
Zantrex Black Side Effects
There’s a lot of caffeine in Zantrex Black, so anyone who’s sensitive to the stuff should beware.
If you want to avoid jitters, a racing heartbeat, and sleeplessness, you may want to start out with just one pill at first.
That way, any side effects you do face will be mild and hopefully won’t last as long.
You’ll also want to stay away from additional sources of caffeine, such as coffee and soda.
The other common side effect is known as “The Niacin Flush”, which we talked about earlier.
The Zantrex Black formula has 30 mg, which is 150% of the daily recommended amount.
This much niacin often makes your skin red and makes you feel like your skin is burning up.
The feeling should only last a few minutes, but it can be very unpleasant, and even a little scary for some people.
Some users expect it, and just let it happen, knowing it will pass. For others, it’s too uncomfortable and turns them away from the product altogether.
Zantrex Black Pros and Cons
Advantages of Zantrex Black
- It’s affordable.
- Just about every Zantrex Blackreview from a customer that I’ve seen says it works as a great appetite suppressant.
Most people say it practically eliminates their appetites.
Disadvantages of Zantrex Black
- It’s got a boatload of caffeine, though we don’t know exactly how much because each of its caffeine sources are included in the proprietary blend that doesn’t offer amounts.
- Lots of people get side effects like stomach aches, headaches, and dizziness.
- You need to eliminate other sources of caffeine while you’re taking it.
Zantrex Black Compared With Zantrex Red and Zantrex Blue
Almost nobody questions whether or not each of these products woks for energy and appetite suppression. They all work. So we move on to side effects.
People who are sensitive to stimulants will have about an equal (and not pleasant) reaction to the Red and the Black. And they both work very well.
Zantrex Blue works as well, but seems to come with fewer problems.
Where to Buy
You can buy Zantrex Black in stores like Walmart, Target, and CVS or online directly through the product site or through sites like Amazon.com.
A bottle of 84 softgels sells for about $25 or less depending on where you go.
This is pretty low compared to similar products, but if that deters you, it shouldn’t necessarily because it is pretty effective in the short term.
Prices don’t vary too much so where you choose will come down to a matter of convenience.
Zantrex Black works.But anyone who doesn’t react well to caffeine or isn’t fond of the jittery feeling that certain stimulants cause will not feel good takingZantrex Black.
Even for people who don’t mind the feeling, I would recommend you treat Zantrex Black as a short term supplement to boost your efforts or push you through a stubborn plateau.
It’s not the kind of supplement you want to be taking month after month.
The heavy stimulant effects will probably keep you from wanting to take it month after month anyway, that is.
And if you do decide to try it, do so with caution.
Start with just one pill so you can experience any side effects more mildly. Be prepared for the Niacin Flush.
Drink a good amount of water and wait it out.
It shouldn’t be long, then you’ll be left with the energy and appetite suppression you’re looking for.

Does the job!
WATER is the key to dispensing with the nasty side effects of face flushing, heart palpitations and tummy ache. you must take each softgel with at least 8 ounces of water. I take one softgel with 16 ounces of water and have no side effects with each dose. My appetite is well controlled and I find I have an abundant amount of energy for each workout. Using this to lose those final 15 pounds which are the hardest. Love this product!

Only on day two
After reading all of the horrible reviews I was skeptical if to actually give them a go. But since I'm a hardhead I bought them and tried them the next day. I drank about 8 oz before drinking the pills (2 softgels) and about 10 more ounces after drinking them. Within 20 minutes I have loads of energy and it controls my appetite. One thing though, I only take a dose a day. I couldn't imagine taking 6 pills in 24 hours. And yes I've lost weight overnight. Literally 5 lbs gone overnight. I was shocked. Even thought my scale was broken so I bought another lol. Yes it was true 5 lbs gone. And my stomach even looks different 🙂 super pleased with this product. I'll update again by the end of week one 🙂

I've only been taking it for 5 days and I've lost 10 pounds already. My schedule doesn't allow much time for exercising right now so I needed the strongest version for now. The jitters have decreased daily and I find myself eating as a necessity, by that I mean I have to remind myself to eat, instead of eating as a hobby. I wish I had found these pills sooner!!

Works for humans like nitrous works on cars!
This product is to humans as nitrous works on cars. Too much and you'll blow your engine. I recommend taking only one pill at a time. Two pills is too much to start out at if your body is sensitive to caffeine. Do not take more than 5 a day though. 2-3 pills taken at different times of the day are good enough if you're in need of it. But the itchiness is really only temporarily, unless you take more than one at a time. Take one at a time! Otherwise you'll end up like these poor guys in these other reviews. And make sure you need to take the pill, because that much caffeine will keep you alert for a good while!

It really does work!
I have been taking Xantrex black for a couple months. I take two pills first thing in the morning with plenty of water. That's it. I have so.much energy. And have lost about 35 pounds already. My appetite has significantly decreased, I don't snack anymore, any all around feel great. I might get the niacin flush a couple days a week which is no biggie. No other side effects for me. It's a fantastic product. I will definitely keep taking it!

I have been taking for about 3 months I love it I have lost 40 pounds and keeping on
10 out of 10 people found this review helpful.
I've been taking this for about 3 months now and I absolutely love it! I take 2 in the morning 2 at dinner and 2 at night! I was at 155 due to some steroids because of a bad back injury and 3 months later I'm back to my normal weight 124. These pills are amazing and if you work out with them or even just going to work, cleaning or just moving I think that give you more rapid results as well!

Happy with results!
I am 57 years old and have low blood pressure and am in good health. Since 50, I have not been able to get my weight down and can't eat any less or exercise any more. I tried Xantrex and went from 132 to 129 in one day without diet or exercise. I felt fantastic and appreciated the energy boost. I don't expect to keep that weight loss up each day but even a little help is a gift from God if you, like me, are in good health and don't have the blood pressure issues that some of these other ratings have. I can also see someone who is much younger getting shakes from the caffeine as I would have done in my 20s. However, as I said, at 57, this product is a blessing. Hope this helps.
Zantrex black good and bad
I like it for the most part. It is effective for energy and weight loss, however at times I do experience vertigo while using it.

i took the first dose of Zantrex black which is 2 pills 15min before breakfast. I experienced the flushing, but that went away. Now I'm feeling terrible nausea. When will that feeling stop? And what should I do about it? Please help. -Ashley
Zantrex pills are very strong. Try taking one pill at a time instead of two, and make sure you drink plenty of water. If you still feel nauseous, you should discontinue use.- Rob

Cut your dose in half, take it with a meal, and make sure you continue to drink plenty of water. If that doesn't change things, you may have to switch to something with fewer stimulants.- Rob

I made the mistakYe of taking 2 around noon then another 2 at 6pm. It's now the next morning and I feel like I'm tripping out. My pupils are super small, I'm dizzy, nauseous, spacey, almost a hangover/very drunk like feeling making even water difficult to swallow without it trying to come back up. I slept almost not at all and had the worst heartburn last night. I've had niacin before and most all of these other ingredients. When does this drugged sick feeling go away? I only took 1 this morning thinking it might help balance what I'm feeling. -Jennifer
When you're feeling like this, discontinue use, drink plenty of water (as much as you can) and get as much rest as you can. Once you're feeling better, after a couple days, try just one pill and see how you handle it. If that works for you, stick with the one pill at a time. If not, I don't know what ingredient is causing it, but I'd say Zantrex Black isn't for you.- Rob
