Click Here To See Our Highest Rated Review

Ultra Strength Xenadrine EFX has only been around for a short time but thousands have rushed forward to buy this product. The manufacturer claims that you can benefit from substantial and quick weight loss that has reportedly been clinically proven to work. Following in the footsteps of the manufacturer’s first weight loss supplement, Xenadrine EFX, this product contains all of the same ingredients plus an added special compound which is reportedly used to speed up the weight loss process even more. Bearing in mind that this same manufacturer, Cytodyne, got into a fair bit of trouble with the first product not working, perhaps the new Xenadrine ultra strength version has been modified to meet higher standards.

Bold statements have been made with regards to Ultra Strength Xenadrine EFX and the effects that it can have when using it with hopes of weight loss. These statements have been backed by client testimonials but with the regular Xenadrine EFX, these testimonials were faked and paid for by the company, so perhaps it’s best that you make up your own mind about this product.

Ingredients

The ingredients for Ultra Strength Xenadrine EFX are the same as the old version of the product, but with an added compound that is not listed or well explained. The main ingredients are: Green tea extract, Grape seed extract, L-Tyrosine, Cocoa extract, Yerba Mate, Guarana, Calcium Tribasic, DI-Methionine, L-Theanine, and DMAE. Guarana is a South American version of caffeine, of sorts, and the extracts are pretty self explanatory. L-Theanine is an amino acid which is a byproduct of green tea, and Yerba Mate is similar to caffeine and may give users a stimulant effect.

Product Features

As with many other weight loss supplements, this product claims to be all natural and with less side effects than others. However, although it contains green tea which has been reported to boost the metabolism within the body, these ingredients have not yet been clinically proven to a degree where a positive link can be made between them and weight loss itself.

,p>Guarana and Yerba Mate are stimulants which speed up the central nervous system and may work as thermogenic compounds. While they may help you burn off a little fat, many people don’t like the jittery feeling they may get from them.

Advantages

  • Ultra Strength Xenadrine EFX contains green tea which is a well known anti-oxidant.
  • This product is fairly cheap. You can usually get 90 tablets for under $30.

Disadvantages

  • The manufacturer, Cytodyne, has been in some legal trouble due to false testimonials.
  • This product contains numerous stimulants which may not appeal to some people.
  • Product may cause jitters and insomnia. (See reader comments.)
  • We can’t seem to find an official website for this product at the time of this review.

Conclusion

All natural weight loss supplements definitely hold a powerful place in today’s market. People are somewhat leery of having a lot of synthetic ingredients which may have side effects. This product, while all natural, is full of stimulants which may produce a jittery feeling or keep you up all night and the manufacturer has a terrible reputation. We can’t recommend Ultra Strength Xenadrine EFX at this time but if the manufacturer concentrates on dumping some of the stimulants and adding an appetite suppressant, we will definitely give it another shot.

    Remember to increase your fluid intake and if high blood pressure is a problem for you do not take any diet pills they constrict your vessels increasing your BP even more.

    This stuff works awesome, at first got jittery and had heart palpitations when I had four at once…. So don’t do that and follow instructions carefully. I have been taking 2 in the morning and exercising right away for 15min then only have piece of toast even though you will no longer feel hungry. :) 10/10 for weightless and a 6/10 for how you feel taking it.

    This is my fourth day on this, and I haven’t lost any weight. I have also followed the direction that was given on the bottle. It has also kept me up most of the night. I will continue with the product though.

    This stuff works, but it still has a lot of caffeine in it. 1 pill= 1 cup of coffee, which means if you take the prescribed dosage (2 pills, 3 times a day) it’s the equivalent of drinking 6 cups of coffee a day. So if you already drink a lot of coffee/soda, I wouldn’t recommend taking Xenadrine on top of that.

    So today was my first day taking & boy did I get the jitters! But I’m blaming that on the fact that I don’t intake any soda, coffee or anything else that contains caffeine. However, I loved the boost! Instead of goin to the gym today I worked out w Jillian Michaels ‘problem areas’ On-Demand & WHOA my body is on fire & has definitely calmed down since.. Just a little somethin 2 get used to but definitely will try it a bit longer to se results :)

    I’ve taken it for a couple weeks now and I’ve lost 10 lbs! It makes me feel more energized to work out and eat less during dinner hours. I do feel jittery, but I have high anxiety anyways and working out helps relax the jitterness. Also the longer you take it the better you can handle it.

    I have used this product for almost a year now. I dont have any of the side effects. I just use it as directed (meaning I read the labels and directions on the box and do my regular work out routine. I usually work out 3 to 4 times a week, 30/40 minutes of cardio, and some calisthenics (total of 1 hour workout). I used to weigh 163 and now im 124. I feel like I have more energy during the day and I feel great

    Today will make a week I’ve been on this product, and I have lost 4 pounds, and love the energy it gives me. The only side effect I felt was a slight headache that went away very quickly. My sleeping is ok I can go to bed okay, I just don’t sleep or too long, and for some reason it calms my nerves

    I’m 20 and not very active. I want to loose weight and have that slim and sexy core. I’ve never been one to turn to dietary supplements but I’m desperate. Manily because they either cause a stroke or you have to keep purchasing the pills to keep the weight off. I heard about xenadrine ultra, bought them at cvs and have yet to take it because I’m scared of some of the side effects. I don’t care about not being able to sleep and I can deal with the jitters. What I want to know is, if I take the pills like recommended and then reach my goal weight, could I stop taking the pills without worrying about purchasing more? Also, I don’t always eat 3 meals a day, so is it possible for the pills the counteract if u skip a meal?

    Well i’ve only been taking it for two days now and i’m a little eerie on taking it again.. i didn’t realize there were harmful side effects to it, i should’ve known there might be but i’ve been told to be careful with these kinds of products and that is starting to get to my head.. i knew it increases your heart rate.. but i didn’t know about the shakiness, being lightheaded.. i like the fact it gives me alot of energy though and puts me in a better mood but i am scared of what everyone is warning me about.. please tell me if i should continue taking this product..

    So, I bought this at Wal-Mart today and so far so good. I can already feel a difference in my appetite. i couldnt barely eat my lunch because i had that feeling that i was stuffed. i have a good stream of energy and i feel happy and not tired and cranky. im 18 and wanted to take this to boost my weight loss goals. im 125 now so it was to loose that hard belly fat workouts cant get rid of. i like it so far!

    Extremely Upset

    I started taking this and it really suppressed my appetite. I was eating next to nothing, working out 5 days a week doing aerobics and after one week I had gained 4 pounds. It made me nauseous and, worse than simply not working, had the opposite effect. A weight loss pill should NOT make you gain weight. I cannot reccommend this product.

    [Reply]

    Tom

    Your body naturaly increases and decreases throughout the day. Duhh. After eating it goes up. After pooping it goes down, after drinking up after peeing up. 4 pounds gain or lose in a short period of time doesnt mean anything. the only way to see if you lost weight is to weigh yourself every day in the morning after a good poop average that out and thats your weight for that week. Ps the only weight lose pill that worked great for me was mega mens taken with a mega mens vitamin supp i lost a pound a day for an actual 7 pounds lost a week. this is with eating 3 meals and the supper was good large portions with the pill i worked out 2 times a day because it made me feel great and made me want to took all my appitite away for snacking. i only ate when i was actualy hungry.

    Just me

    I have lost 4 lbs and I have been using it for 2 weeks. BUT I have been walking a mile once or twice during the week. I do feel jitters at times but they go away. I have been able to go to sleep with no problems. And I also have not been able to eat as much as I normally would. Even when I want to eat I cant. I love it so far

    [Reply]

    mike

    how can you say it doesn’t work after one day? This supplement is a thermogenic (sp?) it raises your bp which you had an adverse reaction to.

    This will undoubtedly give you some insomnia and make you jittery when you start taking it, give it a few days and you the side effects should start to ware off.

    I am very uneasy about diet supplements..but I tried this one. Im not a coffee drinker so caffeine really effects me. I was affraid i waould get to jittery so i stuck with 1 pill 2 times a day. I took it with a 16 oz glass of water both times and waited 20 minutes before eating. I didnt work out, but i counted my calories 1450.00 per day. I had more energy and lost 20lbs in 2 months. I started getting lazy, and decided to go off of it because i reached my goal weight.. i didnt gain it back like everyone says. if you continue to count your calories youll be fine.. but this product helped me to speed up my metabolism..oh and for added info. i had a baby and worked out for 1 year. couldn’t lose the last 20 lbs. after my son was 2 my hubby did research and had me try this. I tried slimquick and hated it. I am not a paid FAKE fan..this really worked for me. It may just depend on how your body reacts to this.

    Lost 3 lbs the first day. Decided to eat after 6pm the next day and remained at the lower weight. And the next day ate at like 8 pm and gained all of it back lol – goof. Anyways, do not get off track once you see results. And the pills do affect your sleep until you get used to them. I’m a little relieved that there is no ephedrine in them.

    [Reply]

    will

    Eat 5 times a day all in smaller portions. Eating once a day in a sense you leave your body with no nutrition most of the day. It should really help

    Hi everyone. I have been taking these type of supplements for many years. A couple of points. Take it in the morning on an empty stomach with a full glass of water. Try to hold off breakfast for 45-60 minutes. Take another dose (2)late afternoon. Say 4:00. If u take it sooner it will cause you to snack b4 dinner. Take it no later than 5:00 or u won’t sleep. For improved weight loss, either do a workout in the evening or go for a brisk walk after dinner. These products do work but you have to do the rest.

    This stuff greatly reduces my appetite.. but I haven’t checked my weekly weight yet, so I’m not sure. I check tomorrow, so I’ll let everyone know if it worked on me. Oh and this does make me jittery and give me insomnia.. but so did the original stacker 2, and the worked a miracle on me. I was eating all t he fattening stuff in the world, and still lost 60lbs… I miss ephedra :/

    [Reply]

    Isaac

    Definitely not safe. This stuff technically raises your BP, so it might be alright until you have a high BP attack. Funny thing is, most people I know with high BP have faster metabolisms… you should probably just cut down your daily calories.

    i took one pill last night and have taken 3 for today (breakfast,lunch,supper) i have not felt jittery which is surprising for me because medications tend to affect me quite a bit. maybe if you try to not think about it so much you wont feel so jittery.. also i took my pill yesterday at around 5 and was asleep by around 130 am which is fairly normal for me.

    well,depends on what time you took at did you let it free? take it around 4 and head to the gym,do a 45 minutes cardio and you’ll be good;)

    is the ultra xenadrine the powder you put in your drink? I don’t like anything that gives anxiety, I took a diet pill once and felt so wierd, I almost called 911, I think it might have been a panic attack, but I’m on anxiety meds now, ativan and klonopin. Now I love coffee. Anyways I have several different types of weight control pills and don’t know what to use. I havecellular research formula, but that’s just for colon cleansing.

    I believe this prodcut will work. I’m still in the early stages, only been on for a few days. I’ve noticed a reduced appetite already. The energy boost is outstanding. I have noticed some side effects, but those are to be expected. Jitters at times, rapid bp. No problems sleeping. I’ll post in about a week for another update.
