What You Should Know

View Our Top Choice Today!

Synedrex is a pill form diet supplement that is advertised to help dieters shed fat and water weight by controlling food cravings. This diet pill is also supposed to give dieters an endless supply of energy, block carbohydrates and help to curb food cravings.

Synedrex is manufactured and marketed by the company Metabolic Nutrition. Looking at the ingredients one can see that there are some fat burners on the list; both green tea and garcinia cambogia are well known fat burners that have been shown in some studies to produce results. There does seem to be some disparity among websites that claim this product does not work as well due to insufficient amounts of these fat burners.

List of Ingredients

Chromium, caffeine anhydrous, green tea extract, garcinia cambogia, l-tyrosine, l-carnitine, HPMC, cocoa extract, 5-HTP, and jojoba bean.

Product Features

Synedrex is a diet pill that is advertised to give energy, block carbohydrates, raise metabolism and help dieters to lose extra pounds. Dieters are instructed to take one or two capsules twice daily. On average the product carries a hefty price tag of $50 or more for a bottle of 90 capsules. If an individual two capsules twice daily as the label suggests the 90 capsules will last less than a month.

Advantages

  • Synedrex does have added vitamins and minerals in addition to the fat burning ingredients.
  • The website has nutritional information and other diet related information as well as supplements.
  • The website also contains customer reviews and testimonials.

Disadvantages

  • Synedrex contains copious amounts of caffeine with over 350 mg per dose. This large amount has been known to cause serious jitters, agitation and dehydration when taken over time.
  • At over $50 per bottle on average, this is one of the more expensive diet pills on the market.
  • There is no real diet plan or exercise plan included, just the pills to be taken along with a health and fitness plan of the dieter’s choosing.
  • Once dieters stop taking the pills, there is the chance that weight could return since there was not a learned modification to eating and lifestyle habits.

Conclusion

Synedrex does have many customer reviews and seems to help some dieters to achieve results. It is suggested, as with all diet pills, that users follow a sensible eating and exercise plan to achieve the best results. Overall this looks to be an average diet pill with a very large amount of caffeine in addition to other energy substances. Synedrex is almost like an energy drink in pill form and as such will pose the risks of the same side effects such as agitation, jitters and insomnia as well as dehydration. While the product may provide results it is important to remember that there are much less expensive ways to get caffeine.

    Started Synedrex on Monday and decided to take every other day. So, I’m on my fifth day,have only taken 3 pills thus far and am down 4lbs.

    I am taking every other morning on an empty stomach. First day was very jittery and could feel the energy tingle out my fingers within the hour of taking. With each pill, the jitters have subsided a bit and by 3rd pill there were no tingly feelings.
    I noticed absolutely no hunger pains or cravings the days I take the pill and very little on the days not taking it. I am now very thirsty and drink tons of water.
    I have not worked out yet but plan to start doing so next week.

    I’ve been taking it for abt a month now & I’ve lost 34 lbs. I didn’t get nausea, but I am so thirsty, like I can’t drink enough water. I do an hour cardio 4 times a week. I also notice I have started biting the inside of my jaws n grit my teeth. I didn’t before using the product. ..has anyone else experienced this?

    I have been on synedrex for exactly one week now. So far, I’ve lost 4.5 lbs. I am a fitness instructor on the side and get plenty of cardio in, lift weights as well 2-3 X week. I am amazed at how my body looks! I have a cruise coming up and want to look crazy good in my swimsuit.
    I started off with 1/2 a capsule mixed in some juice. Felt awake and ready to go. Definitely get jittery if I don’t eat a little with it. Very strong appetite suppressant, I had to force myself to eat lunch most of this week. I have moved on to one whole capsule within 45 minutes of waking. I do find myself having a hard time falling asleep, but when I do, I’m out!
    My day job has me sitting at a desk mostly all day and I have found that now I stand a lot at my desk and move around more because I feel the need to just move.
    STAY HYDRATED!!! Make yes to drink lots of fluids or yoi’ll find yourself with headaches and body aches.

    Is it safe to do cardio on this pill? I took it for the first time today. I went running and it took me nearly an hour just to get my heart rate back down and I had only ran 2 blocks. I also feel a little nauseous, but I know that’s common for the first two days.

    Im on my second bottle and have been using Hydravax with it. I run and weight train and have noticed a VERY BIG change. I have dropped about 22 pounds from taking both of these products. I have abs and the “ripped” look. I would recommend this product to anyone, in fact I recommended it to several people I work with and they love it!

    Can I take Synedrex while on high blood pressure medicine?

    [Reply]

    Anonymous

    Synedrex is an upper it can have some adverse side effects if you have high blood pressure it can be very hazardous if I remember correctly it even says so on the bottle. In my opinion no I would not take it until I talked to my dr if I was in your situation.

    My pills were in a bag during travel, and some of the pills broke open and have a crack which allows me to see the powder inside that can spill out(if i tried to dump the powder out) Also, they were in the heat and some had melted a little and are softer now, is that okay to still take these pills?

    I am 28 years old and in good athletic condition. I work out regularly and have taken a few supplements in the process to help me out. I started using Synedrex last Sunday. It was working great;it gave me plenty of energy and curbed my appetite to where I didnt even get hungry and had to force myself to eat. On the fifth day I started getting horrible nausea and tingling in my extremities especially in my hands and my heart felt like it was constantly beating out of my chest. I used the prescribed dose only one pill a day after breakfast. I never had any trouble until the fifth day. I took it the same way on the sixth and within 3 or 4 hours I was having bad side effects. My pulse was raising from low 80′s to 130′s suddenly and my blood pressure was shooting up at the same time. It would come and go. It got to where I couldn’t breathe and was unable to stand up. I even passed out a few times. I was taken to the emergency room just for to be cautious. Everything is fine now that I am off of it. It worked great in the beginning but unfortunately its not for me. So please just be careful and if you do start feeling any side effects then please stop using it. My situation could have turned out much worse had I not been around people that knew what to do.

    i’m having similar effects. only i get horrible nausea, a little bit of tingling, and i get really hot and dizzy. it helps if i keep cool or get something to eat. i don’t know if its the same issue but its pretty scary.

    I had the exact same side effects. I eat before I take it, and I tried taking a day off in between. I stopped taking it, my husband is taking the rest of my supply and hasn’t experienced any of those problems. I think it just isn’t for some people. I am now taking Crash also suggested by my trainer I take it before bed and it helps burn more calories when sleeping, no side effects from this one. I see this is older, did you continue taking and if so did the side effects subside?

    I started taking Synedrex 6 days ago and I am down 7 lbs. I’ve gone to the gym 5 days out of the 6. I had severe jitters the first day but then decided to eat first the next day and try it and it made a huge difference. Protein shake with 2 boiled eggs then the pill and the jitters are gone. Hope this helps!

    Yeah, if you don’t eat within 15 minutes you will get really sick. I found that a bowl of oatmeal and a pear worked great. I started this on a Wednesday and by the following Tuesday I had lost 16 lbs while doing a heavy workout ( low reps, high weight) every day. When I began to do an extensive cardio workout daily that also boosted more loss.

    You have to eat something with it…not just one piece of toast. Big breakfast. Medium lunch. Light dinner.

    I am on my 3rd day using synedrex. I take these in the morning before breakfast….maybe 15mins before. The first day was really bad in the sense of jitters and a crazy caffeine overdose feeling, 2nd day better, still pretty strong, though today 6 hours after taking the tablet I feel really light headed and not as motivated as the first 2 days. I didnt have a problem sleeping the last 2 nights.

    Actually you only take up to two a day I have been using synedrex from about 3weeks and have lost over 20 pounds I only take one pill a day and if you buy from suppliment ware house myou can get it for like 30 for a 45 days supply if you use the price compare to a sketchy website that has a rediculously low price this is my second cycle and I would suggest anyone looking to lose weight use this product also the jitters disappeared after a week or so my rating is a 5/5

    Im in my third day, but i had a question. Do you have to take it everyday or just the days you go to the gym? because i was planning on taking it only on gym days…

    [Reply]

    Ken

    I would take it everyday, but after two months of taking it take a month to two month break from taking it at all.

    That way you keep your body guessing, but keep going to the gym regular schedule and keep your diet the same. DIET DIET DIET. It’s not just the pill doing the job for you. ITS YOU!

    My trainer recommended this product to me, and it’s a great product!

    Sue

    I have been on Synedrex for 4 weeks now I have lost only 8 pounds. I eat less than 1,000 calories a day and I walk for about 45 minutes everyday. Other people comment that they have lost over 20 pounds – what I am doing wrong?

    You’re slowing your metabolism down to shit. Eat 1500 calories a day, evenly over 8 hours and take in no solid food after 6PM. Ephasize lean protiens, leafy greens, and health fats and you’ll shed it. If you want abs stay away from a.b.s. Alchohol. Bread. Sugar

    Valerie

    Wow, Alan. Kinda harsh.
    It is true though, eating less calories wont promote weight loss. I have been on Synedrex for 2 bottles now, with a month break in between and I have had great results. Eat well, keep walking. You need good calories, that’s it. Keep at it. It takes 4 weeks to notice a dfference in yourself, 8 weeks for your spouse to notice and 12 for your friends to notice. Keep it up!

    Anonymous

    you are not eating enough, your body is in survival mode and will not let go of fat stores.

    Anonymous

    Eat more you should be at approx 1800 calories a day.
    By eating clean a proper diet will increase your metabolism. 5 meals a day. Pills will only give you a slight advantage. Keep up your workouts. Weight loss occurs over months. Don’t get discouraged.

    Juan Pla

    Not enough food, too much cardio, and not enough emphasis on weight training. You need to sit with a professional to figure out your specific caloric needs as well as the proper training program for your goals. Blind caloric recommendations will not do.

    Joshua

    I’m willing to bet that you’re not doing anything wrong and that your body and synedrex don’t cooperate with each other.

    i dont think some of yall have tried using syndrex… ive been on it for about 2.5 weeks or so and have lost 15lbs. When you are taking syndrex if you eat more than 1000 calories in a day you feel bloated as crap. I usually only take in around 750 on days I take it and that includes drinking cranberry juice. Seriously, how do yall figure 45 minutes of WALKING is TOO MUCH cardio?!? I go to the gym 4 times a week, lift weights for about 1.5 hours and do 30-45 minutes of running on the eliptical. Lastly, I usually take the pill m-f and take off on the weekends and eat a nice meal on saturday and sunday. This will make you gain a couple lbs from the water your body is now retaining since syndrex eliminates water weight, also will promote speeding up metabolism. So basically I have been losing about 5-7 lbs from m-w then start to level off, gain about 2-3 lbs over the weekend, then 5-7 again m-w so avg around 3-5 loss per week. been working for me so far. ALSO note, weight loss is always going to depend on eating habits, exercise, how overweight you already are or arent. I plan on only taking until I finish the bottle to speed up weight loss to where I want to be and then just maintaining weight.
