What is Glabrinex?

To start with, Glabrinex is a dietary supplement that “suppresses the formation of visceral fat” with licorice flavonoid oil. [1] [2] You take three capsules every evening and that’s supposed to slim down your midsection. Unless you’re out and about in the evening, you don’t have to take them with you.

The supplement, released by Vitamin Research Products sometime after 1979 when the business started, uses only natural ingredients, a good choice. Purchases can be made on the official website and through third-party retailers. We like that the company has been around for more than 30 years and there are some supportive comments, but read on…

Lack of Results – “Just Doesn’t Work?”

The first worry we had is in regards to Glabrinex ingredients. “This is a simple product that makes extraordinary claims,” said our Research Editor. “The formula says a lot about the chance of you losing belly fat and so do consumers.”

“Well…three months and 540 capsules later I recorded a total weight loss of zero, nada, nilch pounds and reduced my belly size by 1/2″ to 39-1/2″,” said one user.

“I’m using it now for about 4 weeks, without any changes in activity and eating habits (I’m a diabetic and used to a strict feeding regimen) and I have lost exactly 0 (zero) grams,” offers a dieter.

Still another says, “Further to my earlier comments: I have used it now for ten straight weeks and my weight has not changed one milligram.”

High Price – “I Paid What for Glabrinex?”

Glabrinex is offered for $64.95 on the official website, but that’s not what dieters claim they paid. “No results at all after paying a large fee to the mail order company. Dr. Jones, Canada, has lost credibility in my estimation,” a buyer explains.

“Gabrinex, like many other “miracle” products is a total ripoff and was an expensive $150 lesson for me,” claims a user.

One customer puts it simply, “I paid a fortune for these pills.”

Our research links one negative, like lack of results, to reduced long-term success. If Glabrinex doesn’t melt away stomach fat, the company claims are invalid.

Is There Any Science?

There is a clinical study listed on the Glabrinex official website. At first the research looks like it supports weight-loss claims, but when you reach the bottom you see it for what it’s really worth. According to the authors, “Ingestion of 300 mg/day of [licorice flavonoid oil] significantly suppressed body weight gain in overweight subjects.” That’s nowhere near the same thing as helping the dieter lose more. At DietSpotlight, words like “could” and “probably” do not signify proof. Without science to back up statements, a supplement can’t be trusted.

What Users Are Saying

“I was 195 #’S now I’m 165…it works for me but exercise while taking increases quicker results ~”

“quick shipping but as for the results I have been taking these for about a week and have not seen any results.”

“I was told that this stuff helps get rid of belly flab, but honestly so far i can’t tell. I haven’t taken the entire bottle yet, so I’ll just keep taking it and see what happens. Not that impressed so far.”

The Bottom Line – Does Glabrinex Work?

So, our curiosity about Glabrinex was satiated easily enough. We like that Vitamin Research Products has been around for more than three decades and the BBB rating is an “A+”, but we are hesitant to recommend a supplement that just doesn’t work, based on consumer reviews. We’re also concerned that the clinical study doesn’t prove weight-loss associated with regular use.

If it’s time to jump start your weight-loss, we suggest going with a blend of ingredients clinically proven to help you lose more. It’s also important that the supplement is affordable.

Among the best products we’ve found this year is our called Burn HD. This formula is a four-ingredient blend, clinically-tested with results often located in studies found in The American Journal of Clinical Nutrition.

Also, we’re so confident that you’ll love our supplement that we’re offering a 2-Week Sample, an amazing bonus.

Glabrinex Ingredients

Glabrinex is a supplement from Vitamin Research Products. The "patent-pending ingredient" is supposed to "reduce visceral fat." There is some research that shows the active ingredient can play a difference in fat loss when taken for a minimum of eight weeks. The participant pool was too small for the results to be considered clinically significant.

We dove into the Glabrinex ingredients to give you the details you need.

Licorice Flavonoid Oil

Licorice is a root found in Europe and Asia that has a sweet taste. It can be extracted and used for things such as flavoring tobacco or medicines.

What is it Supposed to Do?

Licorice can be used to treat itchy scalp, heartburn, and it is said that it can help promote weight-loss.

Clinical Research

There was a study done by the North American Journal of Medical Sciences that proves Licorice helps with weight-loss. They started off by saying, “Human and animal studies have shown that glabridin from licorice flavonoids has a beneficial effect on body weight control.” Then continued on by saying, “KK-Ay mice aged 6 weeks were assigned to 5 groups, and fed a high-fat diet containing 0, 0.5%, 1% or 2% of licorice flavonoids, or 0.5% CLA for 4 weeks. Compared with the control group, body weight gain and weights of abdominal adipose tissues were suppressed in 2% licorice flavonoids group, and blood glucose levels after 2 and 4 weeks were decreased in all three licorice flavonoids groups.”

Medium-Chain Triglycerides

A Medium-Chain Triglyceride is a chemical bond with aliphatic tail of 6-12 carbons.

What is it Supposed to Do?

Medium-Chain Triglycerides are used to prevent muscle breakdown, prevent seizures, or help with weight-loss for people with AIDS.

Clinical Research

There are many studies that have proved that Medium-Chain Triglycerides promote weight-loss. For example, one published in the American Journal of Clinical Nutrition stated that, “MCT (Medium-Chain Triacylglycerols) oil consumption resulted in lower endpoint body weight than did olive oil…Consumption of MCT oil as part of a weight-loss plan improves weight-loss compared with olive oil and can thus be successfully included in a weight-loss diet.”

There was another study in the Journal of the American Dietetic Association that said, “Compared with LCTs (Long-Chain Triglycerides), MCTs (Medium-Chain Triglycerides) decreased body weight; waist circumference, hip circumference, total body fat, total subcutaneous fat, and visceral fat…Replacement of LCTs with MCTs in the diet could potentially induce modest reductions in body weight and composition without adversely affecting lipid profiles.”

Food Starch

Food Starch is a chalky carbohydrate made from glucose in plants. It is found in foods such as potatoes, wheat, rice, etc.

What is it Supposed to Do?

Starch is said to help increase blood glucose levels.

Clinical Research

Though there aren’t many studies proving the relationship between Starch and weight-loss in humans, there has been a study that proved the relationship with rats. A study done by the Critical Reviews in Food Science and Nutrition Journal first said that, “…there is strong evidence demonstrating that RS lowers whole body and visceral adiposity. The magnitude of these changes in adiposity are very large and sufficient to independently improve insulin sensitivity, and reduce the risk of diabetes, CVD, and certain cancers.”

But, when they are talking about humans, they say, “Human data corresponds well with that from rats. RS (Resistant starch), in comparison to DS (digestible starch), does not seem to have any impact on body weight… There is data from mice and humans to demonstrate that RS changes the microbiota in the gut which has been shown to influence energy absorption and the development of obesity.”

Vegetable Glycerol

Glycerol is a clear, sweet substance found in lipids that is used as a sweetener in certain foods.

What is it Supposed to Do?

Glycerol is supposed to help treat constipation, weight-loss, and athletic performance.


Beeswax is a waxy substance made from honey bees. When the bees make it, they use the wax to make cells to holy honey or larvae.

What is it Supposed to Do?

Beeswax is said to help with hemorrhoids, fungal infections, and diarrhea.

Glabrinex Scientific Abstracts

Licorice Flavonoid Oil

Moderately overweight subjects were used for this randomized, double-blind, placebo-controlled study. Total fat mass and visceral fat areas were measured after administration of 300, 600, or 900 mg of Licorice Flavonoid Oil. Body weight, body mass index and blood samples were evaluated at baseline and following 4 and 8 weeks of treatment. Caloric intake was similar, however, total fat mass reduced substantially in the groups ingesting the Licorice Flavonoid Oil, while 900 mg per day resulted in substantial reductions from baseline levels in visceral fat, body weight, and LDL cholesterol. There were no negative effects noticed throughout the study. [1]

Results from the study displayed visceral fat, waist circumference measurements and waist-to-hip ratio substantially reduced in participants who took Licorice Flavonoid Oil in comparison to those on the placebo at the 12th week. Side effects of Licorice Flavonoid Oil were similar to placebo and no adverse effects were reported or trends in toxicology differences in haematology, vital signs or physical exams were linked to the Licorice Flavonoid Oil. The results suggest that Licorice Flavonoid Oil is safe for human consumption as a food ingredient for the prevention of metabolic syndrome. <b.[2]

Medium Chain Triglycerides

Two out of the three participants in the medium chain triglycerides (MCT) group who showed evidence of metabolic syndrome at the start of the study did not show metabolic syndrome at the endpoint. In those in the olive oil group, six participants showed metabolic syndrome at the start while two subjects no longer had metabolic syndrome at endpoint. In conclusion, the results indicate that medium chain triglyceride oil could be added in to a weight-loss regimen without seriously effecting metabolic risk factors. There should be a distinction made on chain length when thinking about the effects of saturated fats on metabolic risk factors. [3]

Food Starch

Commercially used resistant starch is readily available to consumers and could be a helpful addition to food for reducing caloric intake and improving organoleptic and textural characteristics. It may also help with elevating amounts of dietary fiber. Resistant starch has very unique functional properties and could be greatly beneficial to health. These beneficial effects of resistant starch include control of fasting plasma cholesterol and triglyceride levels, glycemic control and mineral absorption. [4]


A 6 week study was carried out, administering a 25% solution consisting of either 7.5 g glucose (placebo) or 7.5 g glycerol to participants of a commercial weight-loss club. Results displayed no substantial extra weight-loss in those on a hypocaloric weight-loss diet relating to glycerol use. The participants ingesting glycerol experienced a mean weight-loss of 4.1 kg and the placebo group 3.2 kg throughout the 6 weeks. In conclusion, the study is in support of smaller studies that came before, using glycerol on a smaller number of participants. [5]

What You Should Know about Glabrinex

Glabrinex is a supplement that claims to reduce visceral fat or fat around the midsection (belly). The official website for Vitamin Research Products, the creators of Glabrinex, lists a research study completed on humans that support their claims of fat loss. Some users may be impressed by the research study, but there are some problems with how the data was collected that could make the results less significant.

List of Glabrinex Ingredients

Licorice Flavonoid Oil.

Product Features

The only ingredient in Glabrinex is licorice flavonoid oil. There are some animal studies out there linking licorice flavonoid oil to weight loss, but all but one has been completed on animals. While this is where most supplement companies start, the effects of supplements and specific ingredients on rodents is not comparable to the effect on humans. Weight gain and weight loss is much more complicated in higher minded species, like humans. Rodents do not typically emotionally eat or go out on a Friday night with friends for drinks and pizza. For this reason, we tend to look for a human study and luckily Glabrinex lists a human-based study for us to peruse.

The human study that is supposed to support the claims of abdominal fat loss made by Glabrinex does nothing but cause more questions. There were no calorie controls used in the study, so the effects of the supplement, reported after the study, are useless. Some of the participants could have significantly reduced caloric intake and that could have caused loss of abdominal fat. On the other hand, the participants could have changed the foods they ate or decided to take up a walk after dinner. These all could have reduced visceral fat.

Vitamin Research Products sells Glabrinex for $49.95. This is far too expensive for a supplement that is not proven to help humans lose belly fat.

Advantages of Glabrinex

  • Some animal studies support the claims of lost belly fat.

Disadvantages of Glabrinex

  • The price is too high for a supplement that is not proven to work.
  • Animal studies do not mean humans will have the same effect.
  • The human study support Glabrinex lacked control.


Weight loss with all-natural products does not have to be a hit or miss situation. Glabrinex lists a human study so dieters can see the proven effects of the supplement, but the human study did not control caloric intake. Dieters were left free reign to change calorie intake and adjust it for weight loss if they so desired. This means the human study is worthless, but animal studies did show some weight loss and fat loss benefits. It is possible that Glabrinex is a great supplement, but they will have to do more research to prove this to dieters who want proven weight loss ingredients.
