A diet product’s worth depends on whether it actually helps people lose weight. Let’s find out if Synedrex really works. We needed to learn as much as possible about the ingredients, side effects, clinical support and customer service. We also took a long, hard look at customer experiences. We processed and condensed to give you the info you need.
What You Need to Know
Let’s start with the fact that Synedrex is a “thermogenic” supplement with B vitamins, caffeine, sulbutiamine, yohimbine extract and other ingredients. You can take up to two capsules a day, though you may want to start with one according to the directions. The small container means there’s no trouble taking them on the go.
The start date of Metabolic Nutrition, the company behind Synedrex, is not listed on the official website, but we know the business started online in 1997. That’s quite a while to be on the supplement market. We like that the ingredients are available for the dieter and the BBB rating for several locations is good, but read on…
I think I may need to get a little more used to it before I can use it as a pre work out.
Side Effects – “Do You Need to Worry?”
The first negative we found was with Synedrex side effects. “No dieter wants to feel shaky and jittery after taking a product,” says our Research Editor. “You can have increased energy and metabolism without the problems.”
As one dieter puts it, “The side effects while on it included excessive sweating, jitters and insomnia.”
Another user reports even more Synedrex side effects, ”It gave good energy, but it was too much. It made my heart feel racy.”
During our research, we did stumble on a few dieters who didn’t have the same problem. One said, “The first day I started I got incredibly hot and enough energy to last a week, had a little trouble sleeping but by day 2 that pretty much went away.”
A customer shared, “I haven’t had any of the side effects listed in any of these reviews.”
Scroll below for one of the best products we’ve seen over the last year.
Ineffective – “Frequent Complaint”
Probably one of the biggest issues with a weight-loss supplement like this is effectiveness. According to some, Synedrex ingredients do nothing to help you lose. “II didn’t lose any weight. I will look for a better fat burner,” a user reports.
Another dieter with the same problem says, ”There was no change in my weight at all.”
We did read some supportive comments along the way. As one user said, “Keeps me going. Makes me sweat.”
Another commented, “I only take one pill per day, in the morning and feel it helps sustain my energy all day.”
You only need one negative, like a negative reaction, to ruin your chance of long-term weight-loss success. In the case of Synedrex, if the side effects are as harsh as dieters report, that’s a bad sign.
The Science – “Is There Proof?”
We visited the Science Center portion of the Metabolic Nutrition website to see if there was any support for the weight-loss product. We found articles about supplements and exercise, but no research. The most important parts are caffeine and yohimbe, two stimulants. We know these ingredients boost energy and promote a stronger metabolism, but too much can do more harm than good. Based on the side effects there may be too much in Synedrex. At DietSpotlight, we need proven facts to support claims. If there’s none out there, or if the formula may cause issues, that’s not a good sign.

The Bottom Line – Does Synedrex Work?
Yeah, so what’s our final take on this one? The business has been around for 20 years and some dieters do report positive results, but we feel uncomfortable giving our support because of the lack of clinical support and potential for side effects. Plus, it bothers us that the bottle only contains 22.5 servings.
If the time has come to shed off the extra weight, our suggestion is to find a supplement that contains clinically supported ingredients, with no known side effects offered at a price you can afford.
Among the best products we’ve found in 2016 is one called Leptigen. The ingredients are a proprietary blend with published scientific research to spur metabolism and boost fat loss. Dieter’s aren’t talking about negative side effects and users report seeing great results.
Also, the company that makes Leptigen is so confident in the formula they’re offering a Special Trial Offer, which we like.

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. The company unfortunately has an unpleasing BBB rating
. 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.
Synedrex is a diet pill that is advertised to give energy, block carbohydrates, raise metabolism and help dieters to lose extra pounds. Identical claims are made by Plexus Block
. 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.

- The website has nutritional information and other diet related information as well as supplements.
- The website also contains customer reviews and testimonials.
- 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 on their official site, 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.
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.

. Similar side effects are often reported with uncertain doses of stimulants like with Adaptogen
or Absolute Nutrition Garcinia Cambogia
. While the product may provide results it is important to remember that there are much less expensive ways to get caffeine.

We researched Synedrex ingredients in order to give you the information you need.
Methylxanthine, also known as xanthine, is a chemical found naturally in body tissues and fluids.
What Is It Supposed To Do?
The main purpose of methylxanthine is increasing alertness in the nervous system, although it may also help asthma.
According to a study published in Canadian Journal of Applied Physiology, “The effects of ephedrine, in conjunction with methylxanthines and aspirin, in humans appear unequivocal but include various cardiovascular side effects. None of these compounds have been tested for their effectiveness or safety over prolonged periods of time.”
You may want to try Leptigen, which has clinically tested ingredients.
Sulbutiamine is a chemical containing two thiamine molecules. It is thought to be found in the brain.
What Is It Supposed To Do?
Not to be confused with sibutramine, an appetite suppressant, sulbutiamine is a compound used for memory, fatigue, and the health of the nervous system.
According to information published by the American Society of Health System Pharmacists, “Although thiamine has not been shown by well-controlled trials to have any therapeutic value, the drug has been used for the management of poor appetite, ulcerative colitis, chronic diarrhea, other GI disorders, and the cerebella syndrome.”
Also known as East Indian sandalwood, the sandalwood tree, where the sandalwood extract is derived from, is not easy to grow due to the specific conditions it needs for proper cultivation.
What Is It Supposed To Do?
Sandalwood extract is used traditionally for aromatherapy, spiritual use, and commercially for perfumes.
In a study published Phytotherapy Research, researchers concluded about sandalwood extract that, “However, until further studies are conducted to determine safety regarding internal use, this herb warrants caution with use.”
Yohimbe is a tree found in Africa. The bark is used to make medicines.
What Is It Supposed To Do?
Yohimbe has been used for a wide variety of treatment, including erectile dysfunction, depression, athletic performance, weight-loss, high blood pressure, and much more.
In a study published in Research in Sports Medicine, researchers studied the effects of yohimbe on athletes. In conclusion, “Nonetheless, yohimbine supplementation appears to be suitable as a fat loss strategy in elite athletes.” This does not hold promising results for those who are not at this level of exercise.
