QuadraLean Review - Does this Fat Burner Work?
No joke – over 50% of diet products simply don’t work. So what about QuadraLean? We took a hard look at the ingredients, side effects, scientific research and customer service. We then concentrated on hundreds of dieter comments and reviews. Furthermore, we took the details, then condensed and refined to give you the info you need.
What is QuadraLean?
First off, QuadraLean is a fat burner that also available in a stimulant-free formula.The ingredients include raspberry ketones , Clarinol conjugated linoleic acid , garcinia cambogia, acetyl-l-carnitine, propionyl-l-carnitine and carnitine tartrate. The suggested dose is three capsules, twice per day. Supposedly it promotes weight-loss by boosting metabolism and increasing energy levels. Ease of use is one positive.
The parent company of QuadraLean, RSP Nutrition, was founded in 2009. You can purchase the supplement through the official website as well as trusted retailers. We do like that there are some favorable and the use of a few natural ingredients, but read on…
QuadraLean Side Effects – “Feeling Bad?”
The first concern we had was QuadraLean side effects. “When dieters take fat burners, results are expected as positives not negatives,” says our Research Editor. “If consumers say the supplement affects them in an unfavorable way, this is not good.” 
“After about 20 minutes my throat itched a little and I got a few red rash patches on my hands. This lasted for a good 30 minutes,” voiced a consumer.
“Made me tired. Felt a little nauseous,” commented a user. 
We did manage to find some buyers who didn’t feel the same. One dieter said, “No health issue regarding upset stomach like others in the past.”
For some the only side effect was less hunger, “I noticed my appetite was a little suppressed but not much.”
Ineffective – “No Weight-Loss”
According to several customers, RSP QuadraLean is ineffective. The formula is supposed to help you lose more, but dieters paint a different picture. “Bought this product and took 6 pills/day (as directed). I did this in conjunction with a healthy diet and regular exercise, product did nothing,” said one user.
“Even with a caloric deficit diet and 40 minutes of cardio 5 times a week, this product did not help,” voiced a dieter.
“No energy boost and didn’t curb appetite,” reports a customer. 
Despite the fact that some of the experiences were lacking, others saw a slight benefit. A dieter reports, “By the 30 mins I felt that I did not have as big of appetite as I normally do in the mornings.”
Some didn’t lose any weight, but they did benefit from the formula. As one buyer comments, “These give me energy but I didn’t lose.” 
Our research shows a single concern, like ineffectiveness, can inhibit long-term success. If QuadraLean doesn’t assist in weight-loss, that’s a big concern.
The Science – “Valid Claims?”
The official QuadraLean website says the product is “scientifically formulated” to support weight-loss. We couldn’t find any clinical studies backing the claims and RSP Nutrition does not give links. For us at DietSpotlight, finding scientific research is critical. If there is no science, why bother purchasing the supplement?
The Bottom Line – Does QuadraLean Work?
Do I have your full attention? We’ve got something to say about this one. After taking a comprehensive look at QuadraLean, we’ve reached a verdict. The positives include a few favorable consumer comments and reasonable price, but we still have some reservations about it because of the lack of published scientific studies supporting weight-loss claims and reported side effects. Plus, we’re concerned about “fad” supplements containing ingredients such as raspberry ketones with no real backing. 
If you’d like to rock your best body, we recommend going with a cost-effective product with clinically proven ingredients and no known harmful side effects.
Among the best products we’ve seen this year is one called Leptigen. The four-ingredient, proprietary blend has been shown in published clinical research to improve metabolism and stimulate fat loss. Dieters aren’t mentioning negative side effects and the word on the web is that consumers are seeing amazing results.
Also, the manufacturers of Leptigen have confidence in the supplement, so they’re offering a Special Trial Offer, a smart choice.
Previous QuadraLean Review (Updated March 20, 2014):
What You Should Know About QuadraleanQuadralean is so named because there are four ingredients in the formula. These four ingredients are supposed to promote fat loss, fat conversion to energy and appetite control. None of the ingredients will work as claimed and Quadralean does not attempt to prove claims with clinical research.
Quadralean: The List of IngredientsClarinol, garcinia cambogia, raspberry ketones, acetyl-l-carnitine, propionyl-l-carnitine and carnitine tartrate.
Product FeaturesClarinol is nothing more than conjugated linoleic acid or CLA. CLA is commonly used as a fat burner. There have been supplements containing just CLA, often in the form of Tonalin, making the same claims as Quadralean. Unfortunately, these fat loss claims are not supported with research. The research completed on CLA proves a movement of weight from fat to lean muscle when taken by people who are already fit. There is no weight loss as the amount of weight lost in fat is regained in lean muscle. Garcinia cambogia is supposed to suppress your appetite and enhance your mood. There is no evidence this Quadralean ingredient has any effect on either. Garcinia cambogia has been included in supplements being investigated for harmful side effects, including liver damage. There is no proof that garcinia cambogia was associated with the side effects, but there’s no evidence to the contrary either. Raspberry ketones in Quadralean are a hoax and nothing more. When promoted on television by Dr. Oz the worth went crazy for the supplement. There is absolutely no evidence that raspberry ketones have any effect on weight loss or fat loss. The remaining ingredients in Quadralean are carnitines. Carnitines are used by the body in the process of using fat for energy. The body uses carnitines consumed in food for the process. More carnitine is not going to boost the effect. There are some claims that carnitine will promote athletic prowess, but these claims are not substantiated with research.
Advantages of Quadralean
- Ingredients for Quadralean are found online.
Disadvantages of Quadralean
- There are no ingredients to promote fat loss in the supplement.
- Garcinia cambogia may be associated with negative side effects.
ConclusionQuadralean falls in with the thousands of weight loss supplements that simply do not work as claimed. Because the Food and Drug Administration does not regulate supplements, they can make some extraordinary claims. Quadralean didn’t even bother to include proven, stimulant-free ingredients like green tea extract and chromium. Sure, the name would have to be changed but at least there would be some beneficial ingredients.
QuadraLean Questions & Answers:
We boiled down hundreds of user comments about Quadralean into this helpful FAQ.

QuadraLean Scientific Abstracts:
Most of the studies performed on humans have been carried out on small samples and typically in short term. None of the studies have displayed an answer for why these effects persist beyond 12 weeks of intervention. Thus, very little evidence supports the possible efficacy and long-term benefits of G. cambogia. Except for rare situations, regarding the toxicity and safety of G. cambogia, there have been no reports of increased mortality and significant toxicity in animal studies. Additionally, at the doses of which G. cambogia is given, there have been no differences noted in terms of side effects in human trials versus controls. 
There were 63 participants who completed the trial (CLA, n = 30). Following the 12th weeks, when compared to baseline, the body weight, subcutaneous fat mass, body mass index, total fat mass, waist-to-hip ratio, and fat percentage had dropped in the CLA subjects (P < 0.05).The CLA group was classified by body mass index and gender. The body weight, subcutaneous fat mass, body mass index, and waist-to-hip ratio had dropped in 27 participants with body mass index ≥ 27, these measurements were lower in females (with the exception of subcutaneous fat mass). The total cholesterol, low-density lipoprotein, triacylglycerol, and plasma fasting glucose levels had elevated, where subjects with high-density lipoprotein had reduced following 3 months of CLA treatment. It was thus concluded that 12 weeks of CLA supplementation in overweight and obese Chinese subjects had provided lower obesity results with no negative effects. 
The meta-analysis results from eligible studies had showed individuals who were administered carnitine had lost noticeably more weight (MD: −1.33 kg; 95% CI: −2.09 to −0.57) and displayed a reduction in body mass index (MD: −0.47 kg m−2; 95% CI: −0.88 to −0.05) in comparison to the control group. The findings of meta-regression analysis had concluded the magnitude of weight-loss due to the administration of carnitine had greatly reduced over time (p = 0.002). Receiving carnitine had resulted in weight-loss.
Raspberry ketones had stopped high-fat diet-induced raises in body weight and liver weight, as well as visceral adipose tissues (retroperitoneal, epididymal, and mesenteric). Raspberry ketones had also reduced these weights and hepatic triacylglycerol following an increase via a high-fat diet. Raspberry ketones had elevated norepinephrine-induced lipolysis. In conclusion, raspberry ketones were found to prevent and improve obesity as well as fatty liver. The effects seem to derive from the action of raspberry ketones in transforming lipid metabolism and raisingnorepinephrine-induced lipolysis in white adipocytes.

QuadraLean Side Effects:
In the world of weight-loss supplements, natural solutions are not synonymous with safety. There is the potential for negative reactions with every formula. Though QuadraLean side effects are relatively rare, that doesn’t mean they don’t exist for some users.
Gas encompasses a variety of different symptoms, like voluntary and involuntary passing of gases out of the body, pains and cramps in the abdomen, a “knotted” feeling in the gastrointestinal system, and bloating . It can last for a long time, but excessive pain can be a sign of something more serious.
What causes gas?
Gas can be caused by food intolerances, artificial sweeteners, constipation, exterior health conditions, and simply swallowing air. Consuming foods high in fiber is also a very common cause of this.
Headaches are pains felt in the head, ears, temple, and other areas of the body. There are also many different kinds, like migraines, tension, and cluster headaches. Symptoms of headaches include pain, sleeping issues, fatigue, irritability, concentration problems, and muscle aches .
What causes headaches?
Some causes of headaches include stress, environmental factors, colds, fever, and physical activity. Scientifically, they are supposed to be caused by changes in blood vessels from brain activity.
Burping is gas expelled from the stomach through the mouth. Unfortunately, excessive burping can cause involuntary vomiting, which can be extremely uncomfortable.
What causes burping?
Burping is usually caused by involuntarily swallowing air. Other causes may include consuming certain foods, eating or drinking too quickly, carbonated beverages, anxiety, medication, and some medical conditions like lactose intolerance or gastritis.
An increased appetite is especially common for growing children whose bodies require more energy to grow. Other mental or biological issues can attribute to this as well. Additionally, this symptom can lead to weight gain if some individual eats more than the body requires.
What causes increased appetite?
Stress, anxiety, depression, pregnancy, mental illnesses, diabetes, herbal supplements, and prescription medications can lead to an increased appetite. This symptom very rarely means there is a bigger issue at hand.
Although it isn’t guaranteed that individuals will suffer from QuadraLean side effects, there have been reports of gas, headaches, burping, and increased appetite, just to name a few. To protect yourself from potential problems, it is always the best idea to consult with your physician before taking any supplement, especially if you’re taking prescription medications, are under 18, have a medical condition of any kind or are pregnant or nursing.
Quadralean is a stimulant-free supplement that’s supposed to help you burn more fat and lose weight. Without the ingredients like caffeine, we often find side effects to be rare. That is the case this time around, but there are a few reported by customers.
“Gave me bad gas problems.” Jessica
“This makes u burp alot.” Jose
“Didn’t do anything except make me burp.” Mat
“I got headaches for the first few days and did not lose fat any quicker than regular diet and exercise.” Kari
“Waste of time. If anything it made me want to eat more.” Jay
“I have never bought a fat burner that actually made me want to binge eat until this one.” Matthew
“Quadralean seemed to make my cravings worse.” Sam
“I got very irritable and snappy.” Sara
“It gave me a headache.” Jose
“I maintained weight. Gave me heartburn.” Michael
When it comes to side effects, Leptigen is one of those supplements that comes with very few, based on customer reviews. That’s one reason why we like the formula.
Quadralean is an appetite suppressant and energy and metabolism booster from RSP Nutrition. There are no stimulants in the formula, so you won't get that kick that comes with caffeine. When looking at the ingredient list, there are a few good ones in there, but as a whole we'd hoped for more.

We went through Quadralean ingredients in order to give you the scoop on this supplement.
CLA, or conjugated linoleic acid, is a chemical found in certain fatty acids. It has become a popular ingredient in many weight-loss supplements.
What Is It Supposed To Do?
CLA is thought to help treat cancer, obesity, and allergies. It is also used by some bodybuilders to increase muscle mass.
According to a study published in the Journal of Obesity, “Overall, it appears as though that CLA helps to reduce BFM [body fat mass] and SAD [sagittal abdominal diameter] in patients, but minimal effect on BMI [participant body weight] or body weight.”
Garcinia cambogia is a fruit that naturally grows in Southeast Asia. It contains hydroxycitric acid, which is the primary source of its health benefits. It became popular after Dr. Oz featured the ingredient on his show, mentioning its ability to help one lose weight.
What Is It Supposed To Do?
Garcinia cambogia is consumed to treat poor exercise performance, joint pain, constipation, and obesity.
One study, published in Evidence-Based Complementary and Alternative Medicine, concluded about garcinia cambogia, “…definitive conclusions that Garcinia/HCA supplements are efficient tools against various health problems especially obesity remain to be proven in larger-scale and longer-term clinical trials, despite substantial public interest in such supplements.”
L-carnitine is an amino acid that can be either produced naturally in the human body or synthetically for various supplements. It can be converted to other amino acids, depending on what the body needs.
What Is It Supposed To Do?
L-carnitine, when consumed through supplements, is used to treat infertility, diabetes, anorexia, fatigue, seizures, attention deficit disorder, heart attacks, chest pains, and more.
According to the International Journal for Vitamin and Nutrition Research, “L-carnitine supplementation does not promote weight loss in ovariectomized rats despite endurance exercise.”
Research published in peer-reviewed journals are important when choosing a weight-loss supplement. Leptigen, which contains tested ingredients like Meratrim and ChromeMate, is the strongest we’ve found this year.
