SlimGum Review

The product is made by an established company and would be easy to use, but whether or not it would have an effect beyond that of any normal chewing gum product is not clear.

Claimed weight loss benefits

SlimGum is claimed to work as an appetite suppressant, targeting just the one key area of weight loss.

How SlimGum Works

woman wondering how diet pill works 538

SlimGum is similar to normal chewing gum. It looks similar and is said to taste similar, however, this gum contains a selection of ingredients that are thought to encourage weight loss. It is suggested that you take no more than four a day in between meals when you begin to feel hungry. Read more about the effects of chewing gum on the appetite here.

The idea behind SlimGum is that you are keeping your mouth busy and therefore your mind is taken off food, which will supposedly stop you reaching for snacks between meals. SlimGum also contains ingredients that have been linked with weight loss and are supposedly released as you chew. However, it is not clear whether it features these ingredients in big enough quantities to make a large difference.

Normally gum is said to suppress cravings through the action of chewing, which in turn may send signals to the brain telling it it’s eating and thus fooling the body into believing it’s not. Unlike regular gum, Slimgum also contains six ingredients that are claimed to “work in synergy to stave off hunger”. It is said to ‘aid weight loss, help cravings and maintain a healthy and energetic metabolism’.

The action of chewing the gum purportedly releases these extracts that are quickly absorbed through the lining of the mouth through a process called sublingual absorption. ‘Sublingual’, meaning literally ‘under the tongue’, refers to a method of administering substances via the mouth in such a way that the substances are rapidly absorbed via the blood vessels under the tongue rather than via the digestive tract.

Green coffee bean extract

This ingredient goes by many other names, one of which is the Arabica green coffee beans. This is the unprocessed version of the black coffee beans and they contain a higher amount of the chemical ‘chlorogenic acid’ because they have not been roasted. Green coffee bean extract is thought to affect how the body handles blood sugar and metabolism. Green coffee is popular for its supposed ability to aid weight loss.


Thiamin is also known as vitamin B, a water-soluble vitamin. It is an essential nutrient that cannot be produced by the body. It is said to be essential for energy and macronutrient metabolism. Its work in Slimgum may be to help the body convert carbohydrates into energy. Thiamin is found in a lot of the foods that we eat. Because of its water-soluble quality, this ingredient is thought to get to the bloodstream faster via the mouth than via the stomach.


Chromium is a mineral that is required by the human body in very small quantities. It plays a role in the regulation of blood sugar levels through the control of insulin. Insulin is a hormone that your body uses to change carbohydrates and other food into energy. It supposedly enhances the action of insulin, which in turn is said to help metabolise carbohydrate, fat and protein in the body more efficiently. Chromium is sold as supplements and is said to help people with diabetes lower blood sugar levels.


Biotin is another vitamin in the group of B vitamins that Thiamin is included in.

Green tea extracts

The active extracts in green tea are polyphenols and caffeine that are said to have the ability to induce thermogenesis and stimulate fat oxidation, boosting the metabolic rate without increasing the heart rate.

In a study reported on in the American Journal of Clinical Nutrition, it was found that green tea extract resulted in a significant increase in energy expenditure (a measure of metabolism), plus also had a significant effect on fat oxidation. While some of the effects were originally theorized to be due to the caffeine content of green tea, the researchers discovered that the tea actually has properties that go beyond those that would be explained by the caffeine.

The same amount of caffeine as was in the green tea, administered alone, failed to change energy expenditure in other studies. This led researchers to believe that there is some interaction going on with the active ingredients of green tea that promotes increased metabolism and fat oxidation


This is said to be an antioxidant derived from the amino acids lysine and methionine. It is supposedly responsible for transporting fatty acids from the cell fluids into the mitochondria, the powerhouse of the human cells, for the generation of metabolic energy. This in turn may release energy for the body to use for its daily activities.

Key SlimGum Ingredients


There are six main ingredients in this product; these are: Green Tea, Chromium, L-Carnitine, Thiamin, Biotin and Green Bean extract. The slimming gum looks very similar to any normal chewing gum and has a peppermint taste, however, the taste is said to soon disappear after 5 to 10 minutes.

All of the featured ingredients are anecdotally linked to weight loss, however, the ingredients may not be featured in large enough quantities to have a major effect. If so, chewing normal gum could work equally well to take your mind off snacking or to suppress your appetite a little.

Green Tea

Green tea is obtained from the Camellia sinensis plant and is believed to hold a range of beneficial health properties. It contains polyphenols and caffeine, both of which are thought to be useful for weight loss.

Green Coffee Bean Extract

This ingredient is taken from the beans that are used to make coffee, but in their un-roasted form. Green coffee bean extract is thought to be able to increase fat burning through its main active ingredient, chlorogenic acid.


Chromium is known as a trace mineral because it is required by the body in very small amounts. Most people get plenty of chromium from their daily diet, but it has been suggested that chromium supplementation can help to boost weight loss.

Clinical Studies

Clinical Researcher 538

There have been no clinical trials for SlimGum proving its effectiveness and so instead we must look into the key ingredients to see how these may work in aiding weight loss. A clinical trial is a reliable method used to test the efficacy and safety of a product or an ingredient.

Green coffee bean extract

A clinical trial that was 22 weeks long, was conducted using 16 overweight adults. These subjects received 1050mg of green coffee extract, 700mg of green coffee extract, or placebo in a cross-over style study, whereby one treatment was taken by each subject for six weeks, before they had a two-week break and then took the other treatment for a further six weeks. Measurements were taken throughout the trial. The results indicated a significant reduction in body weight. It is reported that there were no significant changes to diet over the course of the study, and concluded that green coffee bean may be beneficial for weight loss.

Green tea extract

A review study of green tea extract considered the results of a number of studies that tested the effects of green tea extract on weight loss and weight maintenance, using overweight and obese subjects. The authors found overall that green tea may be able to cause a slight increase in weight loss in overweight and obese individuals, but that this increase is not likely to be significant or of clinical importance. They did not find any links between green tea and weight maintenance following weight loss.

SlimGum Side Effects

Woman With Stomach Ache 538

SlimGum reviews do not generally mention many side effects other than that taking too many can lead to needing to visit the toilet more often. It is possible to determine some other possible side effects by looking at each individual ingredient within the product.

Green Tea Extract

Some sources recommend 100 – 750 mg per day of green tea extract as safe for consumption. Children are not advised to take green tea extract as trials have not been carried out on minors.

Green tea extract interacts with some types of medication. The list is not exhaustive here, so it is advisable to consult with your doctor before taking any product with any amount of polyphenol in it. Green tea extract will interact badly with medications for heart conditions, some antibiotics and sedatives.

It should be safe to consume the recommended dose of four pieces of SlimGum daily if you do not consume a lot of caffeinated products during the course of your day. To read more on this look here.

Green Coffee Bean Extract

The highest recommended daily allowance for green coffee extract in the body is said to be 1600mgs. In clinical research, no side effects have been recorded but, keeping in mind that green coffee contains caffeine, therefore it can cause side effects related to caffeine especially when taken as a supplement along with regular coffee.

WebMD provides a list of potential side effects. These include headaches, nausea, jitteriness, insomnia, anxiety, increased heart rate, and high blood pressure.


There is no recommended daily allowance for chromium intake but some sources recommend the minimum amount of chromium a person should take a day to be 20-25mcg in women and 30-35 mcg in men. It is not then conclusive how much Chromium is the upper limit intake for humans. There appears to be a bigger risk in a deficiency of Chromium intake than excess.

A daily dose of four pieces of SlimGum should contain 200mcg of Chromium. The amount of chromium ingested may be termed safe in the short term. To read more, look on WebMD.

Although not common, the side effects of chromium intake are ‘occasional irregular heartbeats, sleep disturbances, headaches, mood changes, and allergic reactions’. Chromium may also increase the risk of kidney or liver damage so if you suffer from liver or kidney dysfunction. Talk to your doctor before starting SlimGum.


WebMD deems L-Carnitine likely safe for most adult consumption, though there are some potential side effects which are ‘stomach upset, nausea, vomiting, and restlessness. It can cause a “fishy” odour of the urine, breath, and sweat’. The good news is you are unlikely to suffer from these side effects unless a certain quantity of this amino acid is taken.

They also say that L-carnitine is related to acetyl-L-carnitine, and there is some concern that L-Carnitine may increase the number or seriousness of seizures in people prone to having seizures.

How to Use

Woman With Pills 538

The manufacturers of SlimGum recommend four pieces of gum to be chewed daily, preferably in between meals, when people normally get cravings for a snack.

The SlimGum website says, “The more you chew, the more actives are released into your system”. Chewing the gum will supposedly help you suppress your appetite, target fat and release functional actives directly into the blood stream, working faster and more effectively than conventional diet pills.

They recommend, however, that you use this gum in conjunction with a healthy diet and exercise. They have included a diet plan on their site. The science of weight loss still remains the same. If you burn more than you put in your body through food and fluids, you lose weight. If you burn less than you put in your body, over time, the excess will accrue to extra pounds.

Overall Verdict

SlimGum offered an alternative to the usual pill-type of dietary supplement. It was claimed to have an appetite suppressing effects and was easy to use – like a normal chewing gum. However, scientific evidence in support of the product was lacking. The company behind the product is well-established, but it does not offer money-back guarantees on its products. SlimGum has been discontinued and so is no longer available to buy from any retailers – online or on the high street.
