I just started taking zantrex 3 and I feel that is working well. I am in a new stage in my life and have not been motivated to do anything.

I started taking zantrex 3 to lose wieght but in fact, I have become motivated and happy.

I have read a few reviews and found numerous negative comments on the product. I believe that people do not take the product as recommended. The bottle states to drink 8-10 ounces per pill and to eat 30 minutes after taking it. The product states that you have to eat in order for the pill to work correctly.

When I first used the product I did not drink enough water nor did I eat because I figured I would lose more wieght if I did not eat.

I was wrong and with healthly foods and exercise this product will work. Before you take any diet pill make sure you read CAREFULLY on how to use the product.

I took Zantrex-3 for 6 months and lost 15 kg (33 lbs.)

The first month it did not work at all, then I started working out and began losing 2 pounds per month. Then I started eating only vegetables at night, and I started losing 1 kg (2 lbs) every week.

So to lose weight, you MUST workout 4 times a week for 1 hour, and eat vegges or low calorie foods at night.

Side Effects:
1) Jittery and nervousness: caused accident while I was driving. 2) Paranoia: I thought my boss is going to fire me. I became very sensitive to what people said to or about me. 3) Knees: my knees dried up along with my skin, I had pain in my knees when I walked and ran and I had to hydrate my skin a lot.

Finally, would I use it again? Yes, because this is the only thing that works!

I took this pill earlier this week. I was driving with my 2 year old in the car and had to pull over and call 911.

I started to sweat, got blurred vision, my hands got tingly and I had difficulty breathing. I was rushed to the hospital, and had these symptoms all day long.

The doctors were concerned about my heart and are continuing to run tests on me. I would STRONGLY discourage anyone from taking this pill.

I have taken just about every diet pill made and this is the only one that gave me an attack like that.

I've been taking this for the last 3 years and I am determined to stop taking the pill since we are planning for a new baby.

I've been off the pill for only 1 week & have had a headache ever since (caffeine withdrawal).

I also notice that I feel so so tired now. It did help boost my energy level - especially to exercise daily so NOW it is extremely hard to stop using the product.

Good luck if you are thinking about starting this pill!

With walking for 40 minutes every weekday as well as doing 20 minutes of cardio training daily, I went from a fat size of 280 lbs. to 190 lbs. in 9 months using Zantrez 3.

I never experienced any side efects.

I took two a day - one in the morning and one before dinner. A few nights I couldn't sleep right away, but eventually it got better.

I took this and had bad side effects. I got so sick to my stomach and had bad sweats. I do like it though, because I am less hungry and have more energy.

I took Zantrex-3 at 9 pm and now it's almost 3 am and I can't sleep. I've got a stomach ache and feel like throwing up.

This has never happened to me before until I started taking these pills. Today was my first day. and I'm not taking Zantrex-3 ever again. I'd recommend not to take this product because it has severe side effects. My stomach is on fire and my ears are itching now.

All diet pills, including Zantrex-3 are not miracle pills. They are accommodations to your diet and exercise program. If you combine all three together you should lose weight.

I am a 24 year old male and went from 245 to 185 in 8 months. Yes, I felt jittery, and yes I had panic attacks.

Do not take it 5 hours before you sleep.

Remember, weight loss is all about mindset too, you have to change your lifestyle to lose weight.

I am probably the biggest hypochondriac in the world, and I had all the negative effects on these pills and once I realized that a lot of it was in my head, I could take the jitteriness and extra energy. Mind over matter.

And don't let some peoples' testimonials scare you from taking it, everyone is different, you never know till you try.

I have been using Zantrex for a while and have seen an energy boost, as well as a slight bump in weight loss from what I was getting with good exercise and diet.

I take only one before meals, not two, and I make sure to drink the eight to ten glasses of water the bottle recommends. I don't recommend taking it if you aren't going to exercise regularly, because if you don't burn off some of that extra energy, I could see how it would give you the jitters.

Good product, but, not for those who are not suited to caffeine.

I am 16 years old and am trying to lose my last 15 pounds that diet and exercise simply will not allow me to lose. I decided to try Hoodia/Green tea pills first because they are mild, but they didn't do much, and now I am taking Zantrex 3.

When I first took them, I got very jittery and hyper, but those are the only side effects the pills have had on me. I feel more motivated to workout due to the energy and I definitely think these will be the boost I need! I would recommend them to anyone needing to lose more than 10 pounds!

Editor's Comments: Rachael, we recommend reading the warning label... these products are not recommended for people under 18 years of age.

Zantrex did help me lose 10 pounds in two weeks.I'm now a pound lighter than I was before I got pregnant with my son who is now a year old. But am I the only one who always feels hungry now that I'm not taking the pill?

I usually do not have a good appetite because of stress and all but now that I stopped taking Zantrex-3, I want to eat all the time!

I feel like im pregnant again but I'm not! I went back on them today.

Today is my first day using this pill. Everything was fine, until right now. It's 4:22am and I can't sleep. I'm trembling and my heart is beating fast and it hurts. I'm really scared. After reading these reviews i think I'm going to end up in the hospital. I'm only 16 years of age also. If I make it through the night, I might try to take only 1 pill instead of 2.

Other than the side effects this pill works. I took it while I was extremely hungry, then when it became dinner time, I ate very little.

Editor's Comments: Product warning labels are there for a reason. As well as containing a ton of caffeine, these products are not recommended for individuals under 18 years old.

I have been trying several different types of diet pills for almost 8 years, with Xenedrine w/ Ephedra being the best of them all. With Xenedrine no longer available, I've been trying others.

Zantrex-3 has been the worst. I have never experienced so many negative side effects. Still haven't finished the first bottle of 112 capsules. I started taking 1 in the morning, and 1 before my afternoon workout.

First time, I got itchy palms. Yes, I drank a full 20 oz bottle of water with it...and ate breakfast within 30 minutes after taking it. After the first dose, no side effects until today. I later increased to the 2 capsules, twice daily.

I have approximately 20 capsules left after taking 2 this morning with 20 oz of water and a serving of oatmeal 20 minutes later. I have never felt so uncomfortable in my life (child birth is right up there). I started feeling jittery, then my face started burning - like a sharp tingling effect all over my cheeks, chin, forehead, and my palms were very itchy again. The back of my neck was a little tingly and very itchy for about 10 minutes.

I have not lost weight. It does give me that burst of energy when I need that cup of coffee or to get motivated for the gym. No addiction here, cause I forget to take it over the weekends.

Good product if you're looking for energy, but after today's effects.... no more for me.

I tried Zantrex 3 years ago and will never forget that horrific rainy night. This happened the week between Christmas and New Years of that year.

I was working the graveyard shift and took a couple Zantrex pills at around 8PM.

At 9:30 PM I began to feel strange and decided to lie down on a couch in our office. After a couple minutes I got up because I had to continue working on my project.

The feelings grew worse and by 10PM I decided to leave the office and drive home. It was pouring rain outside so that made the drive difficult enough, but the side effects I was feeling from the pills magnified the horror.

My throat closed up, I opened the windows for air, and then I began to vomit uncontrollably out the window of the car. I pulled over and continued vomiting out the door.

It was a miracle how I finally piloted myself home, but as soon as I got to my garage, I began to vomit once again. I got out of the car and started to walk towards the elevator of my condo and my knees buckled and I could hardly walk.

I thought I was having a stroke or a heart attack. When I got upstairs, I called 911 and an ambulance arrived at my home and took me to the emergency room.

At the ER they took many blood tests and after awhile I had severe diarrhea in a bed pan.

By 4:00 a.m. I was feeling much better and they sent me home by cab.

I would seriously advise against taking this product or any diet product. It's not worth the horrid side effects, because I thought I was having a heart attack or stroke and was going to die. The physical response to the drug was amazing, and not in a good way.

I have used zantrex 3 for a couple months and yes the 1st time I tried it (only one pill a day), I felt jittery for a couple hours. I found out that if I took 1 zantrex 3 with 1 Relicore (also a weight loss pill) it evened out the side effects (Relicore also helps with anxiety and stress).

The combo is perfect - good energy, good mood, and I also didn't feel hungry.

So start with one dose each day (together in the morning) and when you feel ready move up to taking the second dosage. Drink plenty of water and try to work out at least 3 times a week and you will be in good shape!

Okay. I thought there was something wrong with me. I took the pills as directed. Ate correctly and drank plenty of water. I fell asleep that night feeling fine at about 11:30 pm and an hour later woke up.

The next five hours were pure torture. I had severe depression, panic attacks, and nausea. Every time I about drifted to sleep the panic gripped my stomach again. I was terrified that I was going to die.

I was so scared to turn on a light or open my eyes because I believed something terrible was going to happen. I've found out that if I take one or two pills a day this doesn't happen.

I would recommend starting out this way (with 1-2 pills per day) and increasing to the directed amount over time.

I have no history of any of these symptoms and even had to look them up. Unless you want to have a terrible night or paranoia and panic attacks, be careful how you use Zantrez 3! There should be a better warning on the label!

Well I have lost another 3 pounds for a total of 6. I haven't even used the entire bottle yet. I have had NO SIDE EFFECTS at all but caffeine doesn't bother me.

I have been taking 3 pills a day and usually don't take them at all on the weekend. I do make sure that I eat right, drink lots of water and I have been going to the gym. The Zantrex has really helped me get over the points when I am stuck on my weight loss.

It does make you, as another user said, tinkle quite a bit. I am sure that it is water weight but saying that I having been doing this off an on for a little over a month with no weight gain, it just continues to go down.

My suggestion is to try it. The Zantrex is like anything else out there - it might work for you it might not. We are all different so you will just have to try it and see if it works for you.

I've Had Zantrex-3 for a day and have had no bad side effects. I've had to use that bathroom a lot more, only to tinkle though, probably from the increased intake of water. Jitters and a hyper feeling also but it's helped me stay awake and alert.

From what I can see though, it really depends on a persons lifestyle. I'm used to drinking about 3-4 cups on coffee with loads of sugar a day along with a few Monsters, also going to bed late and waking up early.

I also eat fruit and oats when taking Zantrex, two at a time 15 before eating. I've already lost 4 pounds! I would recomend it to people you are used to LOTS of caffine. Anyone who takes it easy on caffine should watch out.

This product REALLY works! I just left a post on another website because I want everyone to see. I am 26, Asian, 5'2" and 125 lbs and want to lose about 15-20lbs for a vacation in 8 weeks.

I began taking Zantrex-3 last Thursday and yesterday (Tuesday), I weighed myself and had lost 5lbs! Amazing!

Editor's Comments: What Gina has lost is mostly water weight -- not fat. Please see this blog post to learn how to properly assess success (or failure) with any diet or fat burner. (End of editor's comments)

No amount or cardio has given me such results in as short a time. This product may be dehydrating, so PLEASE drink plenty of water throughout the day. I run to the restroom to *tinkle* about 15 times a day. The food suppressing part really worked for me, and I feel full after a small meal, but get hungry again after about 3 hrs. That's a good thing, though! Then you could have 5 small meals or snacks throughout the day, keep your metabolism running, and feel full.

This is my first time taking diet pills, so I was nervous about taking them. I started off slow by taking 1 pill before breakfast and 1 later in the afternoon before my evening workout. The first 3 days were uncomfortable with the jitters, felt flushed and hot, and had trouble sleeping at night. Now, I don't experience any of that.

I have so much energy throughout the day and during my workouts (which I do about 3x a week) and don't have any trouble sleeping at night or waking in the morning.

I'm happy with my results after taking only 2 pills a day! Good luck everyone! I hope this review helps.

I started using Zantrax 3 last week. I lost 3 lbs the first week. I had no side effects at all. I started with 1 pill in the morning and 1 before lunch.

This week I started with 2 pills at a time and still have no side effects. You really need to read this bottle, if coffee or tea give you a caffeine jolt than maybe you shouldn't take this pill.

Caffeine really has no effect on me at all. I am trying to lose 15 pounds. I will keep you updated but so far so good.

I took the product for three days. The first day I was very jittery, just as I had expected I would be.

I had an energizing work out, very little sleep, but overall it seemed fine. The next day I took it exactly the same, drinking tons of water and eating about 20 minutes after each dose.

I noticed I had major mood-swings and was extremely irritable. Very little sleep the next night. On the third day, I was completely lacking concentration, moody and emotional and was up the entire night anxious and thinking having very negative/depressive thoughts.

I flushed all the pills down the toilet and will never take them again. I feel "normal" again and am positive the negative effects I was experiencing was from this product.

I have taken Zantrex-3. I agree if you are not used to coffee then a lower dose is required. At first I did get the jitters because I started off with 2 caps. When I lowered it, I felt better. I increased it over time. I did lose weight and I recommended it to people who also told me they lost weight.

I do agree it may not be for some people. I states on the bottle that it work better with food. Some of us take it and decide not to eat but the bottle does not say that. You still should eat something.

Yes, if you do not eat within an hour or two you may feel some discomfort. I took it before every meal and I felt find after a couple of days because I was trying to get the most maximum result but 2 caps was not for me.

We all have to face it DIET PILLS are not for everyone.

I took Zantrex 3 for the first time today and it had me feeling like a million bucks. I dont get how all the people had a bunch of side effects, but different strokes for different folks. Maybe its because I bought mine at the local Safeway grocery store and not walmart or walgreens.

There are a lot of good things about this product. Although it has a high niacin content, I have never had so much energy!

I have almost no appetite, and it think it kinda works as a laxative, because everytime I take it before a meal, I go almost instantly!

Once in a while, my back will spaz out. But other than that, I think its a pretty good product. I'm kinda scared about what will happen when I stop taking it though. The withdrawl and stuff.

I just read all the reviews and I would have to agree It does make you pretty jittery at times.

I had all the side effect with the heart palpitations, jittery-ness, dizziness, upset stomach, vomiting, at first.

After going through it for a couple days I kept the dose low to 1 cap twice a day and I'm feeling pretty great.

I'm 5'2 -- went from 129 to 118 in 2 and a half weeks. As other people said, it does depend on your body and how you react to caffeine.

Overall, I feel zantrex 3 does work....

I've been taking Zantrex 3 off and on for the last year and a half and I have lost some weight. I have experienced some bad and very scary side effects at times but I am determined to lose this weight.

I'm living with an UNDER ACTIVE THYROID and even with my meds I'm still tired alot of the time. This is where Zantrex3 helps me -- energy.

Side effects for me are: itchy red rash, lots of flushing in face and neck, and not so much cutting my appetite all the time, heart racing --I've even stopped taking it at times because I felt like it affected my eyesight (given me blurred vision).

Like I said I'm determined to lose the weight so I just keep on, while hoping everything's gonna be alright.

Editor's comments: Diet pills can exhibit side effects, some of which are certainly dangerous for sensitive individuals. Tammy should definitely stop taking this product, and investigate other options.

I have taken Zantrex 3 for almost 4 years on and off. I only stopped taking it due to a pregnancy. I use this product with portion control and exercise. I only allow myself a serving of food during meals and I take walks daily as family time with my children.

I love the energy it gives you. When you first start taking it there is some "jitteriness" you will experience but it lessens the more you take it. I don't have a problem with panic attacks normally and don't drink coffee.

I have never had a fear or need to go to the hospital after taking it. If you take it with a meal you should be fine. I love the extreme energy it gives you.

I have recommended Zantrex to a lot of friends and family. Some loved it and some didn't. I assume it is not for everyone. After a few months of taking it others were commenting that I had lost weight but I didn't weigh myself until about 6 months after taking it. When I did weigh myself I had lost about 50 pounds.

After that I continued using it to lose weight. After 2 years of taking it I have lost 137 pounds. I went from a size 28 to a size 13. During my pregnancy I gained 42 pounds. I waited until my child was 2 months old before I started taking them again, and I've lost 48 pounds since his birth.

Some due to my diet and exercise I'm sure but I'm continuing to lose due to Zantrex 3. I would love to contact the makers of this medication simply to thank them for a wonderful product.

I recently started taking Zantrex-3 and I started getting really nauseated especially in the mornings before breakfast.

When I took my second dose before lunch I felt like I was going to vomit all day, I couldn't take my 3rd dose. The second day I woke without having to take any and felt the same way I felt yesterday without the Zantrex.

Needless to say after 3 days of taking the medicine it took me another 3 to lose the side effects. I wouldn't recommend this medication to anyone -- unless they like feeling nauseous, restless, paranoid, and enjoy panic attacks.

I have only been taking this pill for 3 days and I feel awful.

The first day that I took the pill, I followed the directions to a T and I ended up going to the hospital because I thought that I was having a heart attack.

I have anxiety and I just suffered from a major panic attack. I haven't had one in a long time.

When I read the reviews and see that other people are feeling the same way I am, I am decided to stop taking this pill. I feel so sick after taking this pill and from the looks of it, so do a lot of other people.

I would not recommend this to anyone. I'm sure not taking it anymore.

I took Zantrex 3 on and off for about 8 months. I ended up losing about 80 lbs on it, probably a good 30 lbs in the first 2 months.

It gave me a bit of an active bowel, and some jitters, but it didn't phase me too much -- obviously -- for me to be on it for so long.

One very bad thing is once you go off of Zantrex 3, you'll never be able to do what you used to do when on it.

It was hard keeping up the same energetic schedule when I went off of the pills.

Anyway, the choice is yours.

I have taken Zantrex on and off again for 7 or 8 months and I love the results.

However I have experienced extreme paranoia which has almost resulted in panic attacks. Once in awhile I'll get really bad stomach cramps about 15 minutes after taking the pill. It feels like menstrual cramps only worse. They'll usually last until I get in some sort of comfortable position to ease the pain and eat something.

I'm a coffee drinker but Zantrex contains too much caffeine -- it does really help get things done though. I do get very "jittery" and I can't sit still for long. But I really can't argue with the effects, they're great.

I decided to try Zantrex a few days ago.. I'd heard a few good things about it and wanted to give it a try.

I took the first dosage in the morning, before breakfast. It definitely suppressed my appetite. I couldn't eat breakfast. Good right? Not exactly. By the time I realized I WAS hungry, my blood sugar was so low I was shaking. I figured I just needed to have some lunch, but took the 2nd dosage before lunch. It didn't suppress my appetite.

I felt extremely sick from the caffeine. Keep in mind I am someone who consumes 2-3 energy drinks or cups of coffee in a day... and had only one cup of coffee that morning.

I went home and tried to take a nap.. I felt like I was going to throw up all day. It was a terrible feeling.

Unfortunately, I can't take them again. I am not even sensitive to caffeine, but these pills made me feel horrible. I didn't have a panic attack or need to go to the hospital, but I could hardly function.

I hope my review helps someone else...

I took these pills for about a month and I did notice increased energy right away. I didn't lose any weight, but didn't gain any either. I did feel jittery for about half hour after taking them, but that was to be expected.

I would like to tell everyone not to take them close to your bedtime, because sleeping is out of the question when you have just taken Zantrex 3.

However, I feel these can work with proper diet and exercise. I'm actually going to go and get some tomorrow. Wal-Mart has them for $19.99 for an 84 count bottle.

I took Zantrex 3 a few years ago and went from 150lbs to 122lbs in 3 months (right before I got married). I'm on them again after having a baby since it's the only thing, besides ephedra, that works for me.

I have had a few issues with it, but they are the exception and not the rule and usually are experienced if I either don't eat after my dose or take the doses too close together. I've experienced:

~mild hives (twice)
~jitters and/or hyper (after breakfast dose)
~racing heart (few times and only if I don't eat)
~panic attack (once)
~moodiness (occasional)

I have similar reactions if I drink too much coffee.

The first time I took Zantrex-3 I took two pills before breakfast. It made me kind of race and gave me tons of energy. The only side effects I got were "jitteriness" being hyper and lots of energy.

The only time I had a bad reaction was when I took it without a meal. I got really sick and real shaky. Other than that i think its good for energy.

You just need to take it with water and a meal. I've been on it for 2-3 weeks and I'm doing fine. Guess it depends on the person.

I always saw this on TV and wanted to try it. So I bought some and I took this about 3 years ago for the first time.

Not too long after taking two pills I broke out in cold sweat and didn't feel too well, an hour or so later later my skin started to itch, soon my whole body began to itch. I felt large bumps all over so I took a closer look and noticed I had huge bumpy red rashes all over my body. I had a fever and I was disgusted by my rashes and couldn't stop scratching for two or three days straight until the rashes went away, this was the worst thing that I've ever taken!

I was trying to find reviews but couldn't find any back then until now. I guess I'm not the only one who got nasty rashes.

I took zantrex 3 the first time and within 20 minutes, I thought I was going to pass out. I got all itchy and turned red.

I took some benadryl and felt better. I tried another dose the next day and the same thing happened. I later found out that it was a reaction to the serious amounts of niacin in Zantrex 3.

My advice? Don't bother... too many bad reviews to even try it!

I just started taking Zantrex 3 today and I feel fine. I'm a little jittery and restless but no other side effects. I'm drinking a ton of water just to be on the safe side though.

I'm looking forward to seeing if I actually lose any weight. I'll be sure to keep you updated.

This stuff threw me into a horrible panic attack. I would have had to go to the hospital but fortunately I had Some Xanax to take.

Like everyone else wrote, DONT TAKE THIS PRODUCT! I will never take another diet pill again, that's how bad it was!

I took 2 pills 15 minutes before eating breakfast and about an hour later I felt like I was going to keel over! My heart was racing. I was sweating profusely. I felt very sick to my stomach. I felt like if I were to sit down, I would vibrate right off of my chair because I was so jittery. It really scared me.

Someone made the comment that this type of reaction is due to a sensitivity to caffeine. I disagree. Although I don't drink coffee, I love my Mountain Dew and Rock Star, which are both high in caffeine.

I have NEVER experienced anything like this from consuming caffeine. It should also be noted that I did not consume ANY other caffeine on the morning that I took the Zantrex 3.

I'm throwing the rest of my bottle away. If any of my friends/family were to consider taking this, I would STRONGLY recommend against it.

Today I took 2 pills as directed right before a meal, and maybe 10 minutes later I was sweating, nauseous and had a terrible headache.

The worst part is it lasted for a few hours. I couldn't even drive because I felt so sick. I WILL NEVER TRY IT AGAIN.

I was totally surprised to read the above comments. I took Zantex 3 and experienced similar problems.

Never having been allergic to anything in my life, I could not understand why I was experiencing this awful flushing and itching. I ended up at the Dr.'s office for a shot. I didn't relate this to the Zantrex 3 since I had been taken the lowest suggested dose and had been doing so for a couple of weeks. Today it happened again.

I determined it was taking it with a multiple vitamin with something in it for high cholesterol. Although the symptoms were not as severe as the first time, I can't believe something like this is over-the-counter. THIS STUFF SHOULD BE REMOVED FROM THE SHELVES.

So if you feel like you need to lose weight, start with your doctor and a nutritionist. Some insurance policies will cover a nutritionist. After all, what good is being thinner if you're dead.

I want a refund because Zantrex-3 is making me very sick. About 45 minutes after taking the product My stomach starts cramping and I feel like throwing-up.

I also can barely walk. I don't start feeling better for many hours. No meds should make anyone feel this way. I've been on these for a few days and realize they are not for me. Please refund this for me.

Editor's comments: Tani, you'll need to contact your retailer for this. We do not sell or fulfill any products and have no affiliation with either the retailers or manufacturers of Zantrex-3.

I just bought Zantrex-3 and im very scared to use it. I've been researching it and I heard a lot of negative things. But I've also heard a few good things. I've tried everything to lose wieght and it just isn't happening.

I'm not sure whether to take it or not. My friend wants to use it too. What should we do?

Editor's comments: The problems most people have with Zantrex are a result of its extremely high caffeine content. If you are sensitive to the effects of caffeine, or you are not used to consuming caffeine, this may not be a product worth experimenting with. Otherwise, you may wish to start out experimenting with the lowest possible dose, while removing all other stimulants from your diet. In other words, if you normally start off your day with a coffee, you may not want to do that the morning you try Zantrex for the first time.

I have been taking Zantrex for about a week now.

I have an eliptical at home and I was very surprised to stay on for about an hour opposed to my usual 15-20min. And when I stopped it was only because my children needed to get to bed.

Otherwise I would have ran along all night. So since then I've been taking 2-3 daily 1 with each meal. I am very sensitive to diet pills and could never stay on them due to all the side effects, however I am a big coffee drinker so I wonder if thats why I am not having any problems.

I do want to say that some of these stories I am reading here are horrible, but I think if your first dose puts you in the hospital or makes you faint there is probaby some other issues going on with your body.

I can say that niacin is pretty powerful and if you're not used to taking alot of vitamins then you might want to stick with 1 a day. So far I really like it and I have cut back on my caffeine as well. I think I' ll work out tonight!

Sara

I am on Zantrex 3 right now, and so far I have gone from a size 16 to a snug size 12 in a little over a month.

Sometimes I get a little bit jittery, but my stomach never bothers me, and it really does help with eating.

But I gain my weight from "snacking" - other than that I lead an active life, so this diet pill helps remind me not to snack, and it gives me a boost.

I like it, and I would at least try it. But it DOES have a lot of energy stuff in it, and I drink about 60 oz's of water a day.

I've tried Zantrex 3 now for about a month. I take only one or one and half pills before eating.. otherwise I get too nauseous.

It does subdue my appetite and give me lots of energy but I'm also losing a lot of sleep and I feel really jittery. I haven't noticeably lost any weight.

Yesterday I decided to stop taking them. I literally had the worst head-ache I've had in all my life. I'm also immensely tired. If I were to lie down right now, I would sleep for hours on end.

I don't recommend Zantrex.

Editor's comments: Severe headaches can be a sign of caffeine withdrawl. Considering the amount of caffeine in Zantrex 3, this is not a surprising side effect.

I think that anyone who is going to try a new product should proceed with caution. There are no two bodies alike.

I tried Zantrex-3 and felt jittery, but had unbelievable energy, mental acuity and a general all-around good feeling. In fear of the effects on my heart, I cut the dosage in half and I don't take it everyday.

I take it before I exercise in the morning and I put in a great workout! It works for me and I am pretty pleased with the outcome. The product gives me the energy and the incentive to be more physical and it does reduce my appetite somewhat, and therefore I have lost weight.

People have to use their common sense when trying anything new. No one knows your body like you!

I've read these comments, and wander why a person who is NOT overweight would even think of taking a diet pill. I have taken it, but I am aware of my body and know that...

I am overweight, so effects are sometimes worth it, but mainly that I know my body can handle the pill to the point where there are not any side effects for me.

My suggestion: make sure you know your body and know how it reacts to normal things in life, like coffee. If you can't drink but two cups and feel nervious, then maybe you should not be taking a diet pill.

This is my second time on Zantrex 3, for the simple reason that I am on my second bottle. I love this product! As a college student, I often have long hours of studying and not a lot of time to work out. With Zantrex 3, I get the energy I need to complete the grueling study hours and I'm still losing the weight I need!

I will admit, on occasion I feel an increased heart rate, but that's really the only side effect I feel and it's not a painful feeling, more like an adrenaline rush.

So, for everyone giving you their advice not to take it, I say it's worth a try. Perhaps you'll feel the uncomfort they feel, or perhaps you'll get the amazing results I have gotten.

For the record, I have just taken the pills(2) approximately 15 minutes ago, finished my 8oz glass of water and I'm ready to eat. AND I FEEL PERFECTLY FINE.
