Great product

By Dennis Whaley, North Carolina, Verified Reviewer

I don't recommend this to anyone sensitive to energy blends or caffeine, but I recommend it to anyone else. Zantrex keeps your insulin levels lowered and increases fat burn during the 4-hour window it is active.

I have been using this product for years and it helps with my lifestyle choices. I do Lean-gains 16/8 protocol, and this is an extremely beneficial product to use. Anyone who has a thing for energy or adrenaline should use this product also. If you are super sensitive, then I don't recommend it (again).

Bottom Line: Yes, I would recommend this to a friend

Do not take this diet pill!

By Amy Susco, Freeport, NY, Verified Reviewer

I purchased Zantrex Black because it was on sale and I wanted to try a diet pill. I took one pill and a little while later I couldn't think straight. I got so confused. My tongue felt like it was swollen and I couldn't pronounce my words. I felt like I was having a stroke. Please be aware of side effects that are not listed.

I needed to give it a one-star rating for this review to be posted.

First time user

By Patty, Texas, Verified Reviewer

I started taking Zantrex Black at the beginning of January. My weight loss goal is 40-45 pounds. I did a lot of research on diet and weight loss pills. I think it’s all a scam, to be honest.

Anyway, I took two capsules before lunch on a Wednesday, and it did give me a boost of energy and curved my appetite. I don’t believe you need diet pills or supplements to lose weight. I believe that if you stop eating fast food and junk food like sweets, candy, fried foods, and “crap food” as my husband calls it, and add an exercise program, you will lose the weight.

I didn’t have any negative results other than just one. The capsules gave me so much energy that I couldn’t sleep. I’ve been awake for over 24 hours, and I’m still not tired. This is nuts. I’ve read reviews where people have had hot flashes, rapid heart racing, even where in some instances they had to be rushed to the hospital. Take it at your own risk!

Bottom Line: No, I would not recommend this to a friend

Beware!

By Jason , Branson, Mo

I just took the recommended dosage and I am having a severe allergic reaction. I'm on my way to get an antihistamine. My skin is red all over, itching and on fire. I'm developing hives, I have bronchitis which my breathing ironically has improved so no worries on anaphylaxis. I am a medic so I'm not worried, but it is very uncomfortable and came as a shock as I am not allergic to anything. Take caution if you use this and DO NOT take more than it says. This could've been worse.

Zantrex Black is no good.

Do not waste your money!

By Jennifer K., Pittsburgh, PA, Verified Reviewer

Though this product kept me wakeful, it also turned me into an insomniac. Though it curbed my appetite perfectly, I lost only ONE pound in one month, AND I was not eating any unhealthy foods NOR WAS I in excess of 2000 calories a day.

This product made me itch all over my body within 20 minutes before I ate. Try something else. This company is only trying a different scheme to make money off of the hopeful.

Bottom Line: No, I would not recommend this to a friend

Horrible, please choose a less harmful dietary supplement

By Catherine , New York

Please do not take this product. They are not clear on the symptoms and mine were very severe. Obviously diet pills make you shake but the way it made me shake was uncontrollable. The very time I took these pills, my skin began feeling tingly and red. I went to the ER thinking it was an allergic reaction but the doctor said this specific diet pill has an insane amount of caffeine in it that my body couldn't handle and my heart rate and blood pressure were through the roof.

Bottom Line: No, I would not recommend this to a friend

Undecided

By Amanda Bruner, New Albany, IN, Verified Reviewer

I just started taking Zantrex Black today. I took it at 4:50, and it's now 7:40 and I'm not sure if my stomach is supposed to feel like this. I feel hungry but sick at the same time. I feel nauseous and tired. I had a burst of energy to where my sister could barely understand me when I talked. I was just wandering if anyone else had these symptoms and if it went away after a few uses? I want to lose weight but being healthy and exercise alone doesn't work for me. I need an extra boost.

Indecisive on product claims

By Kelly, Ohio, Verified Reviewer

I started Zantrex Black yesterday. I felt perfectly fine all evening besides not really being able to sleep and was extremely dehydrated even after drinking five bottles of water, which from what I have been reading seems to be normal.

I woke up this morning and took two pills on an empty stomach. Twenty minutes later I felt really hot and flushed like I was going to pass out, then I was extremely nauseous with bad cramping pains and my cheeks and nose are beet red. After it subsided, I felt fine for about three more hours, but then to my surprise, it happened all over again.

I'm pretty sure it is the Niacin in it that is making people feel this way. It is meant to flush out your system quickly and make you sweat out toxins. As far as weight loss goes, I do feel lighter, but I think it may be from the extra water intake and cutting out high calorie caffeinated drinks. I only recommend this product to individuals who actually eat three times a day, otherwise, you will be dealing with some nasty side effects.

Will never take it again!

By Danielle, Mississippi, Verified Reviewer

I would not recommend this to anybody. The headache is not worth it, OMG, I just took some Tylenol and it eased away within 20 minutes. Don't take this unless you want a BAD headache. I felt shaky, it didn't give me any energy, it decreased my hunger, but heck, that probably gave me a bad headache too. I don't think anything on the market is safe. The hospital said that weight loss pills don't work, they just give you bad side effects, and to me, if you gotta deal with crap like that, it ain't worth it.

Bad experience

By Linda Barber , Orlando fl

I have always struggled with weight and always believed that this "next one" is going to work. To say the least, within 2 days my face was red and blotchy and my kidneys were in a lot of pain, so much that I am seeing a doctor this morning. I drink lots of water and don't understand what this side effect is. Never have I had such pain in the stomach area and kidneys.

Will keep you updated but would not recommend this product.

Hives, rapid heart rate, lightheaded

By Sherry W., Virginia, Verified Reviewer

I just bought these today and I took two this evening before dinner...within 10 minutes of taking them I felt like I was on fire! My face was blood red, my arms and my chest were broke out in hives, my blood felt like it was pounding through my body and I was on fire. It has been about an hour and a half and it is eased up some now. I still feel like my heart is racing but the redness has gone away, however, I will definitely not be finishing the rest of my bottle and I would not recommend this to anyone else, as typically I have no allergies to anything and this is the first time I’ve ever had a reaction like this to any pills.

Bottom Line: No, I would not recommend this to a friend
