A diet product’s worth depends on whether it helps people lose weight. Let’s find out if Synedrex works. We needed to learn as much as possible about the ingredients, side effects, and clinical support. We also took a long, hard look at customer experiences. We broke it all down and condensed it to give you the info you need.
What is Synedrex?
- Methylpentane Citrate
- Sandalwood Extract
Other ingredients include alpha lipoic acid, and poly-thyronine. The company recommends not taking more than two capsules per day. The small container means there’s no trouble taking them on the go. 
The company behind Synedrex, Metabolic Nutrition, started the business online in 1997. Trusted retailers and the official website sell the supplement. We like that the ingredients are available for the dieter and that we found some positive comments, but read on…

Synedrex Side Effects – “Do You Need to Worry?”
The first negative we found was with Synedrex side effects, which could be associated with methylxanthine.  “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.”
Ineffective – “Frequent Complaint”
Probably one of the biggest issues with a weight-loss supplement like this is effectiveness. Clinically speaking, there are some energy boosters in there that could increase metabolism enough to affect calorie burn, but no two dieters will react the same. According to some, Synedrex ingredients do nothing to help you lose. “I 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 an adverse 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, not matter if quality research doesn’t report such issues in most participants, 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 yohimbine,  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 . At DietSpotlight, we need to see facts to support claims. If there’s none out there, or if the formula may cause issues, that’s not a good sign.
What Users Are Saying
“I have taken different types of fat burners, but this product is great as it does not give you jitters like most fat burners. Have not had any side effects other than lots of energy throughout the day. Wouldn’t recommend taking this product late in the day, because you will not be able to sleep. Have seen a great improvement in weight loss.”

“I’m sure this works for some people, but I took this for the first time with food as directed. Not even an hour later I was running to the bathroom throwing up and continued to throw up for the next two hours.”
The Bottom Line – Does Synedrex Work?
So, will Synedrex help you lose weight? 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. Plus, it bothers us that dieters reported side effects and lack of results.
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 this year is one called Burn HD. The proprietary blend is a combination of ingredients shown in 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 Burn HD is so confident in the formula they’re offering a 2-Week Sample, which we like.Learn More About Burn HD »
