Zantrex Black promotes rapid weight loss by expediting the body’s natural metabolic process. They claim this is fulfilled by suppressing hunger and giving the user extra energy. Even with extra energy, it seems maintaining this high level of energy would be difficult if the product is suppressing hunger at the same time.

Some studies conclude a positive correlation between decreased appetite and increases in energy level, which raised our curiosity even more on the efficacy of this product. Our research team has refined their findings to give you the following information.

Zantrex Black can be purchased through their Official Site.

What is Zantrex Black?

Zantrex Black is a dietary supplement manufactured in the US for promoting weight-loss and providing increased energy. It is a liquid pill designed to curb hunger while allowing you to lose- weight, and it gives you the power to continue with your exercise plans and diet.

Though it contains the same formula as the original Zantrex 3, it promises an increased level of potency which maximizes its weight-loss benefits.

Zantrex is not only a fat-burning supplement that aids in weight-loss. It is also energy-boosting due to its caffeine content. The caffeine content is equivalent to consuming three to four cups of coffee per day. Caffeine (as everyone knows) causes severe side effects.

What Users Are Saying

“This product didn’t do anything. I take very good care of myself, workout at a weight lifting gym, have a very clean diet and drink nothing but water. My trainer is a ranked body builder and I asked her about these pills. She told me to throw the bottle out and I did. These kind of pills do nothing but make your heart beat too fast. I took her advice and ordered a CLA supplement and a digestive enzyme supplement. Wow, got the results that I’ve wanted. I’ve lost weight and feel great!”

“I like it but weight comes off slow unless you put effort with it and diet also.”

“The best supplement for weight loss. No jitters after taking it. Love it.”

20 Zantrex Black Reviews

  • Nicole (Verified Purchase)

    Left me with headaches from the minute i woke up till i went to sleep. Stomach pains and gained ten lb!!!!! Even with added exercise and diet in check.

  • It works !
    Chochies (Verified Purchase)

    I have been taking zantrex black for almost a month now. Yes it does creat a sence or urgency and also high energy. Depending on what a persons daily activity may be or work wise as well. I work in fast food so im always on the go. When i take my 2 pills a morning be fore work, I have energy for the whole day. Also the one thing i have to say that is a negative for me. Is that lack of appetite. There will be times that i have to remember to eat . but then again eating fast food on a daily basis is not good or healthy. I believe this product works depending on the person. I also have tried the zantrex 3 and saw results. I can also now wear my 2xl manager shirts that have no give what so ever, and feel confortable. My 3xl shirts are big on me so are my pants but the results are good for me in my eyes. Like i said tho depending on the person and his or her daily and work activity will depend on how a person feels.

  • Connie

    I started using this product 3 weeks ago. So far so good. I’m not having any of the side effects mentioned in the previous comments from others. I will say that you MUST drink plenty of water as this is a rapid release type of formula! I started at 180 pounds and today I’m at 166.8. I completely cut out carbs, fried foods, juice, soda, candy…..anything sugary. I workout 5 days out of the week and 1 day out of those 5 days I swim. Mind you, I have to squeeze this in because I work two jobs but all of my sacrifice and hard work is paying off. I will come back and do another update. HINT: Food prep helped out a lot!

    • Montana (Editor)

      Hi Connie. We’re glad you’ve found success with Zantrex Black! You might want to consider adding another supplement to the mix, one called Dietspotlight Burn. It has natural ingredients and is backed by clinical research.

  • Joyve

    The people giving bad reviews are a little off or something because if they read the directions it said very clear: to test your tolerance you should take 1 pill first, then increase the number, of course they gonna feel a lot of crazy side effects if it was the first time taking the pills… And second, if they read the directions, it also say that you should take the pills 15 minutes BEFORE main meals, I think that you ain’t gonna feel nothing if you take them after your main meals… I recommend everybody that want to buy weight loss supplements to read before buying them. 🙂 🙂 🙂

  • Dee

    Had a bad allergic reaction to Zantrex Black. Face got hot and turned bright red on face, neck and arms. Pretty scary!!

    • Holli Dreher

      Thats because of the B3 (niacin) That is common with this Vitamin.


      This is happening to me right now. Except my whole body is bright red, I feel swollen and sick.

      • Sofie

        I took one Zantrex Black and was ignoring burning and itching all over my body for 15 mins or so…mostly face. I just went to restroom wondering if something was up and saw I’m currently having a moderate to severe allergic reaction. Took Benadryl and hoping it doesn’t get worse. 🙁 I guess I’ll be tired now.

    I took the recommended dose in the a.m. and within fifteen minutes my brain was heating up, face went red like I had a sunburn then my skin turned red and then a rash appeared all over my body.

    • Holli Dreher

    • Ranee

      Same thing happened to me !

    • Montana (Editor)

      Hello Queen Bee. We recommend discontinuing Zantrex Black and consulting your physician about these side effects. You may also want to consider trying a different weight loss supplement, like Dietspotlight Burn.

    • Anonymous

    Karen (Verified Purchase)

    Extreme overall rash, tingling/burning and skin hot to the touch within 15-20 minutes of taking it. If I could give a negative rating I would. Waste of hard earned money. I had to throw it out.
