What is Sinetrol?

To start, Sinetrol is an ingredient, comprised of citrus polyphenolic extracts of red orange, grapefruit, and orange. [1] Supposedly, the extract works by inhibiting the PDE enzyme and stimulates lipolytic activty. [2] In essence, it enhances the fat-burning process. There are also claims it may help boost metabolism and speed up fat loss.

Sinetrol was introduced by France-based company NB Consulting. Throughout the official website, there’s information relating to use, research and applications. We like that we found some favorable reviews and that it contains a few natural ingredients, but read on…

Minimal Results – “Concerning?”

One issue we have is with minimal weight-loss results. “There are numerous user comments and reviews posted online regarding results from Sinetrol ingredients,” said our Research Editor. “But, the science behind it paints a different picture.”

One customer stated, “I noticed no noticeable weight-loss or effect from the product.”

However, a different person commented, “It reduces my appetite and I think I’m losing some weight.”

The opposite was found in other reviews of Sinetrol.

According to the International Journal of Food Sciences and Nutrition, “they received daily for a 12-week period 900 mg of a Citrus-based polyphenol extract, Sinetrol…the efficacy of the supplement improve both overweight process and correlated skeletal muscle mass metabolism.” [3]

Reviews of Sinetrol – “Discouraging?”

Unfortunately, there are quite a few discouraging user comments posted online for Sinetrol. For example, one person said, “Not sure about it. I have been on them for 2 weeks and I have not seen any results at all.”

But, a different customer revealed, “Did the research and haven’t found where anyone lost weight.”

As is the case most of the time, there are positive reviews of Sinetrol.

Another posted, “I read that it offers antioxidant support, so that’s a good thing.” [4]

The research we’ve conducted has revealed that if there’s a certain aspect of a weight-loss ingredient or diet product that is quite difficult or bothersome (minimal results, discouraging user comments, side effects) the likelihood of long-term success is slim. Therefore, if Sinetrol does fail to produce real effects in a lot of people, this could be a major dilemma.

The Science – “Find Any Evidence?”

We at DietSpotlight look for solid science used to support any applicable weight-loss claims. Regarding Sinetrol, there are studies relating to the use of citrus extracts and improved cardiovascular health, fat loss and burning. [5][6][7] The only concern was the amount and the time-frame to see results. While we like that there are some studies, the results are mixed.

What Users Are Saying

"These capsules work amazingly well for my seasonal allergies. Relieve post nasal drip, congestion, & itchy eyes with no noticeable side effects, such as drowsiness."

"Doctor suggested I take this for sinus/colds/allergies and it seems to help for the first day or two then it stops. It did not work for me but the doctor seemed to be big on suggesting it."

"Sinetrol capsules don’t seem to be doing anything for sinus."

The Bottom Line – Does Sinetrol Work?

Will Sinetrol help you lose weight? Well, we like that it contains natural ingredients and that there are some studies relating to efficacy, but the lack of concrete evidence showing users will burn fat and improve long-term weight-loss leaves us concerned . There’s also the issue of consumers no seeing results and the presence of discouraging reviews.

If your’re looking to lose those extra pounds, we suggest going with a product containing ingredients backed by science and connected to positive dieter reviews.

Among the best products we’ve seen this year is one called Dietspotlight Burn. The supplement contains four clinically-tested ingredients, which have been shown to help boost fat loss and elevate metabolism. There’s no mention of harmful side effects and users are talking about seeing great results.

The makers of Dietspotlight Burn are so confident in their product, that they’re offering customers a Special Trial Offer.

We looked into Sinetrol ingredients so we could give you the information you want.

Blood Orange Extract

This extract is derived from the blood orange fruit. The liquid is often used to flavor bakery goods. However, some companies have determined the compound to be beneficial for general health, which is why it can be found in some herbal supplements and medications.

What is it Supposed to Do?

The blood orange fruit contains anthocyanin, vitamin C, dietary fiber, folate, calcium, and thiamine, all of which are essential to the diet and can promote well-being and overall health when consumed in the right amounts. Anthocyanin is considered an antioxidant, which can prove to be beneficial to health as well.

Clinical Research

According to research published in the International Journal of Obesity, blood orange could slow fat accumulation in mice. However, the conclusion derived from this study is not supported by other research studies.

Grapefruit Extract

Grapefruit extract stems from the pulp and seeds of the citrus fruit. It contains compounds like vitamin C, pectin, potassium, and fiber.

What is it Supposed to Do?

Grapefruit extract is consumed to treat various ailments, including different kinds of infections. It is also an important component in natural pesticides, soaps, cosmetics, cleaners, first-aid treatments, and mouthwash.

Clinical Research

A study published in the Journal of Alternative and Complementary Medicine (New York, N.Y.) found that grapefruit extract was effective as an antibacterial agent in humans, something that may be beneficial those wanting more natural treatment options [1].

Sweet Orange Extract

The sweet orange extract is derived from its juice and peel. The compound contains significant amounts of vitamin C and potassium, which may be the reason it is proposed to have many health benefits for the body.

What is it Supposed to Do?

When consumed medically, the sweet orange extract is used to treat acid indigestion, colds, kidney stones, high blood pressure, high appetite, high cholesterol, and even cancer.

Clinical Research

Unfortunately, a significant amount of research testing the effects of sweet orange extract does not exist. However, one study published in Animal Science Journal found that the compound may have a beneficial effect on the immune response for broiler chickens. Another study, published in Molecular Nutrition and Food Research, found that certain chemicals within the extract may potentially play a role in lung cancer prevention in humans [2].

We’ve been keeping an eye on a product that offers four clinically tested ingredients; Dietspotlight Burn.


Sinetrol Scientific Abstracts

Sinetrol is known to have 2.1 more activity than guarana 12% caffeine all while possessing 3 times less the amount of caffeine. There were two groups of participants (10 individuals in each group) with a body mass index high enough to be considered overweight were observed throughout a 4 and 12 week study where they ingested 1.4 g per day Sinetrol as well as placebo. Participants in the Sinetrol group experienced a decrease of body fat percentage with a substantial difference of 5.53% and 15.6% respectively, following the 4 and 12 weeks. Body weight of the participants reduced with a large difference (2.2 and 5.2 kg respectively) following the 4th and the 12th week. The effects of weight-loss were attributed to Sinetrol polyphenolic composition and its synergistic activity. Sinetrol was found to be a powerful trigger of PDE (cAMP- phosphodiesterase) at 97% in comparison to narangin , cyanidin-3 glycoside and caffeine. In conclusion, it has been indicated that that Sinetrol contains powerful lipolytic properties which are controlled by cAMP-PDE inhibition. Sinetrol was found to prevent obesity by reducing body mass index. [1]

A randomized, controlled, double-blind study was carried out for a period of 12 weeks. Sinetrol-XPur was administered to overweight participants two times per day along with each meal in one group (N=47) compared to a placebo group (N=48). Hip and waist circumference along with belly fat were reduced in the tested group in comparison to the placebo group (p < 0.0001) (-5.71% versus -1.56% for waist circumference, -4.71% versus -1.35% for hip circumference and -9.73% versus -3.18% for fat). Inflammatory markers were then noticed to decrease. There was a notable reduction of oxidative stress as noticed by the decrease of malondialdehyde (-14.03% versus 2.76%) as well as an elevation of glutathione and superoxide dismutase (4.63% versus -2.36% and 17.38% versus 2.19%, p < 0.01). There were no adverse reactions noticed within the study. Results suggest Sinetrol-XPur is a useful tool for decreasing abdominal fat and reducing waist and hip circumference while enhancing inflammatory and oxidative status in overweight human subjects. [2]

Overweight male participants in a randomized, double-blind trial were observed following consumption of 900 mg citrus-based polyphenol extract (Sinetrol XPur) per day for 12 weeks. Before and following the intervention period, body composition, blood and anthropometric parameters were closely observed. Following the 12 weeks, metabolic framework was substantially improved with a suppression of skeletal muscle catabolism. The results of the trial indicate that over a 12 week period of time, the effectiveness of the Sinetrol XPur supplement correlated skeletal muscle mass metabolism and improved both overweight process.

What You Should Know about Sinetrol

Sinetrol is more likely to be added to other weight loss supplements than found for sale as a standalone product. Created by NB Consulting, a French company, Sinetrol is a fat burning ingredient that can be purchased by supplement companies for use in their products. Sinetrol is derived from fruits and claims to be a 100% food product. There are no stimulants in the fat burning ingredient, which is uncommon for a fat burner. When searching for Sinetrol, we could not find any product listing this ingredient. Information on the official website was last updated in 2008.

List of Sinetrol Ingredients

Extracts of red orange, grapefruit and citrus.

Product Features

Sinetrol is a relatively unknown ingredient in the weight loss world. The ingredient claims to have fat burning potential, but there are no stimulants to increase heart rate. Stimulants are commonly used as fat burners because increased heart rate leads to calorie deficit which means the body will burn more calories stored as fat. If Sinetrol does have fat burning capabilities, they would not reside in this theory. Interestingly enough, the name Sinetrol is not far off from synephrine. Synephrine is derived from the bitter orange tree and is a fat burning ingredient in many weight loss products. Synephrine is a stimulant, however, and in some cases can cause health issues in dieters who use the product for extended periods of time. Whether Sinetrol and synephrine is the same product, we cannot be sure. The Sinetrol website offers no information on the exact make-up of the ingredient. No products are listed that contain the ingredient either. What is offered is a list of product companies that offer Sinetrol for sale. None of these companies are based in the United States and none currently sell weight loss supplements containing the ingredient. There is no pricing information available for Sinetrol as it cannot be purchased by an individual for home use.

Advantages of Sinetrol

  • All natural sources.
  • The official website offers a list of retailers selling Sinetrol.

Disadvantages of Sinetrol

  • There are no known weight loss supplements using the ingredient.
  • Sinetrol may be a brand name for synephrine.
  • Sinetrol cannot be purchased by dieters directly.
  • The official website was updated more than two years ago.

Conclusion

If Sinetrol was a good fat burning ingredient, weight loss companies would not need to include stimulants in their formulas. There is no known way of increasing fat burn without increasing heart rate. Stimulants increase heart rate and Sinetrol does not contain any stimulants. Dieters wanting to try Sinetrol to increase fat burn may have difficulty locating a supplement using the ingredient. We could find no supplements listing Sinetrol on their ingredient lists and the official website offers no leads in this regard.

      It could be your body is adjusting to the formula, as we’ve encountered with some dieters. However you must make sure the formula is safe for you. Did you ask your doctor about the symptoms? If it isn’t safe for you, than try another product that is, for example Dietspotlight Burn is a good option that is clinically proven to deliver results.
