There’s a bit of curiosity surrounding Jadera, so we took a deep look into the ingredients, side effects, clinical research and customer service. Furthermore, we scrutinized hundreds of user comments and reviews. Then, we condensed and refined to give you the info you need.

Jadera Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What is Jadera?

First off, Jadera ingredients are bitter orange, cassia seed, Job’s tears seed and mulberry leaf. The supplement promotes weight-loss by boosting metabolism, burning fat and suppressing appetite.  The recommended serving is two capsules per day. One bottle lasts a month. The small bottle makes it easy to take on-the-go.

Jadera USA is the company behind Jadera. The company has been around since 2010. You can buy it on the official website and through Amazon.com. We like that we found some favorable customer comments and that it seems affordable, but read on…

Side Effects – Not the Greatest Feeling

The first issue we’re concerned about is Jadera side effects. “Dieters look for supplements to help them lose weight,” said our Research Editor. “Based on this profile, you may want to think about potential adverse reactions.”

“I started having shortness of breath. It was scary, so I stopped taking Jadera,” reported a dieter.

“I have been taking Jadera for just 2 days. I already feel the rapid heartrate,” stated a customer.

Based on customer comments, side effects aren’t necessarily negative. “Definitely felt the energy boost,” commented a user.

FDA Alert – “Concerned?”

The company behind Jadera was contacted by the Food and Drug Administration in October of 2011 related to an undisclosed ingredient. The result was a public notice from the FDA about the supplement containing sibutramine. This prescription medication was removed from the approved list in 2010 due to potentially serious side effects. This was the second time the business received the warning. The same issue arose in 2013.

Lack of Results – “Losing Weight?”

The lack of results from Jadera ingredients was a concern mentioned by customers. “I have finished my first bottle and haven’t lost one pound,” a user says.

“I have been taking Jadera for 2 months now I haven’t noticed any weight change,” another dieter reports.

According to some dieters, they noticed results while using this one. “Lost a few pounds. Not what I expected, but better than nothing,” said a customer.

Another stated, “Curbed appetite and lost weight. Not so bad.”

Based on our research, something as simple as lack of results is enough to offset chances of long-term success. If Jadera ingredients don’t work to help you lose weight, there’s a chance you’re taking the wrong supplement.

The Science – “Backed by Research?”

You can find all sorts of information on Jadera, but you won’t find any mention of clinical studies connecting the ingredients to weight-loss. Both synephrine and sibutramine are associated with some negative side effects. At DietSpotlight, research is essential to the review process. But, when studies show a formula is connected to adverse reactions, this is concerning.

The Bottom Line – Does Jadera Work?

So, what’s the final take on Jadera? Well, we like we found a few positive comments and that it’s relatively inexpensive, but we’re skeptical about this one because there’s no connection between the ingredients and side effects. Also, FDA warnings, negative side effects and lack of results reported by customers leaves us concerned.

If you’re stoked to lose weight now, we suggest going with a supplement containing ingredients proven to work and not connected to harmful side effects.

Among the best supplements we’ve found in 2016 is one called Leptigen. The formula is packed with four clinically-tested ingredients shown to spark metabolism and jump start fat loss. There’s no talk of harmful side effects, but we found plenty of dieters reporting some fantastic results.

Also, the makers of Leptigen have enough confidence in their product to offer a Special Trial Offer – impressive.

Previous Jadera Review (Updated March 14, 2014):

What You Should Know

Jadera claims to be a powerful weight loss supplement, that offers to help you lose up to 38 pounds in one month. Safe, healthy weight loss is no more than two pounds a week, so this seems to be a highly exaggerated claim. Still, we will take a closer look at the ingredients to see what the fuss is all about.

List of Ingredients

Jadera does not provide a full list of ingredients, but there are a limited number of ingredients available from third party reviews. These ingredients include: bitter orange fruit extract (synephrine), cassia seed extract, mulberry leaf extract, jobstears seed, and medical starch.

Product Features

Bitter Orange fruit extract, also known as synepherine, is a natural cousin to ephedra. It is thought to produce the same fat burning benefits, without all the harsh side effects. Cassia seed extract is a natural laxative designed to help regulate the bowels. Mulberry leaf extract is thought to be able to help control blood sugar levels, and is a natural diuretic to help remove water weight from the body. Jobstears seed is another natural laxative. Medical starch, claims to be able to reduce the amount of fat your body absorbs from your foods, but there is not any medical evidence or research to support the claims.


  • Bitter orange is proven to help burn fat.


  • There is no money back guarantee.
  • At $50 a bottle, this product is expensive and does not have quality ingredients to match.
  • We cannot see how much of each ingredient is in the formula, so we don't know if there is enough to produce results.
  • The Bitter Orange and natural laxatives made lead to negative side effects including: nausea, diarrhea, loose stools, headaches, jitters, insomnia, and anxiety.
  • They do not disclose a full ingredient list. Without the full ingredients list, it seems like the company is trying to hide something.
  • They do not disclose the ingredient amounts. Without the full amounts of the ingredients, we cannot really tell if the product is safe or not.


Due to the lack of full information about the product's ingredients and ingredient amounts, combined with the exaggerated weight loss claims, we do not recommend you use this product. If you choose to use this product anyway, do so with caution, following the directions on the label. Instead, we recommend you continue your research to find a product you know contains proven amounts of proven ingredients for weight loss including a combination of appetite suppressants and fat burners. Then, for the best possible weight loss results, follow a balanced diet full of fruits, vegetables, and whole grains. Combine the balanced diet with a balanced exercise program, and drink more water.

Jadera Side Effects:

Although JaDera is generally considered a safe weight-loss supplement, it is known to cause some side effects. While this doesn’t necessarily mean that you will have issues, it’s wise to exercise caution.

Rapid Heart Rate

Also known as tachycardia, rapid heart rate is a condition in which your heart beats at an abnormally high speed. This can be dangerous for you. A fast beat means that not enough blood gets to your body. Thus, your organs and tissues are left without the blood they need to work properly.  You can often feel your heart beating too quickly. You may also experience shortness of breath, light-headedness, chest pain, and fainting.

What causes rapid heart rate?

Tachycardia is the result of your heart’s natural electrical impulses being interrupted. Some of the most common conditions that provoke rapid heart rate are fever, overactive thyroid, and high blood pressure. [1]

Dry Mouth

Dry mouth can be extremely irritating. It’s when you don’t have enough saliva in your mouth. As a result, your mouth gets dry and sticky. Because you don’t have enough saliva, it’s not uncommon for dry mouth to lead to bad breath, gum irritation, and chapped lips.

What causes dry mouth?

Dehydrations is among the chief causes of dry mouth. There are also many medications that cause dry mouth, especially those used for treating depression and inflammation.


When you’re nauseous, you feel like you have to vomit. You experience malaise, bloating, sweating, and stomach pain. You may even have mild abdominal contractions.

What causes nausea?

Many people suffer from nausea as a result of motion sickness, which happens when you’re on a boat, plane, car, or amusement park ride. Nausea is also a direct result of infection from stomach viruses and bacteria. Other causes of nausea are ulcers, gallbladder disease, and some forms of cancer. [2]

Shortness of Breath

This is when you have a hard time breathing properly. Breathing becomes hard and uncomfortable. You feel like you can’t get enough air, or you can’t breathe quickly enough.

What causes shortness of breath?

Lung and heart disorders cause shortness of breath. These disorders include asthma, pneumonia, and chronic obstructive pulmonary disease.  Shortness of breath may also be a sign of heart attack. JaDera is normally free of side effects. If you’re worried about how your body might react to the ingredients, talk with your doctor.

I started with Jadera in the purple label then the white label and lot 25 lb. My Co worker has lost 30 and another lost 90 lb make sure it’s the original.


How many did you take per day to get those results?


I’m just curious.. A year ago I’ve started out taken Jadera (regular) and lost weight. I decided to start up again but decided to go for the stronger dosage of Jadera. I’ve been taken for 2 months now and notice no change in weight. Why?

Hi Mel. There’s really no way to determine if a supplement will work the same way twice in a row. Maybe they changed the formula??

Hi, Rachelle. We have a few concerns with this product; namely the supposed poor results, side effects and legal trouble that dieters report.


Is it possible for your palms to itch? While on jadera

Ive been taking Jadera for a week now and have gained 2 pounds. No side effects. Am I doing something wrong?

Arnold (Editor)

Hi Mary, it could be that these pills are simply not taking effect for you. Try improving your workout or diet regimen. If still nothing browse our reviews for alternatives.


I’ve been taking Jadera for about 3 weeks I was having trouble losing the weight I was going up and down with my weight from 298-310. Now I weight 282. I know it’s not a lot but it is a start. the only side effects I encounter is dry mouth and insomnia but that is my fault for taking the pill a bit late since my work hours vary. I do get the energy I need. I do recommend to drink plenty of water Through out the day. The bottle of jadera I have it does give me the ingredients and mg contains. the best part of these pills I do not crave sweets or sugars. It works for me and I am in love with this product I will be taking it for about 7 more weeks. I will keep and update to see how much weight I lost. Good luck to everyone on this journey if I can do it I am sure you can too.
