SlimVits Review

SlimVits is a weight loss supplement that has its own dedicated website. The retailer claims that the product is prescription strength and can help you to lose weight quickly and easily. A list of five ingredients is provided on the SlimVits website, but it is not clear if this is the full ingredients list and no ingredient quantities are disclosed.

The product is manufactured in China and can be purchased from several websites. It is said to suppress the appetite and boost the metabolism. Whilst some of the ingredients mentioned in the product have been clinically studied, none have been scientifically proven to work in these ways.

SlimVits Claimed weight loss benefits

The main claims about SlimVits made on the official product website are that it can suppress the appetite and boost the metabolism. Precisely how the supplement achieves these effects is not made clear. The ‘How it Works’ section of the website states that the green coffee extract present in SlimVits is the active ingredient; it is claimed that this ingredient has effects similar to ephedrine. The green coffee extract is said to act as an appetite suppressant and to increase blood pressure and heart rate, supposedly increasing the metabolism. There is no mention of how any of the other ingredients are supposed to work or why they have been added to the supplement.

How SlimVits Works


The product website states that SlimVits can stop cravings and suppress the appetite as well as having a positive effect on the metabolic rate, helping you to lose weight fast and ‘feel like the old you’. SlimVits is therefore claimed to target two of the five key areas of weight loss: appetite suppression and metabolism boosting. There is a ‘How it Works’ section on the official product website, but there are numerous mistakes in the text, making it difficult to read. The description also only pertains to the claimed effects of one ingredient, despite the manufacturers naming four other active ingredients in the supplement.

How Each Ingredient Works

Green Coffee Extract

Green coffee extract is the main ingredient in this product and has been said to target four of the five key areas of weight loss: fat burning, metabolism boosting, carbohydrate blocking, and appetite suppression.

It is the caffeine in green coffee beans that is believed to have a weight loss effect. Caffeine is a stimulant and as such, it acts on the central nervous system. By triggering the ‘fight or flight’ response, caffeine is believed to give the body more energy and heighten alertness. The stimulant is also said to help to boost the metabolism and increase the process of fat burning. It is thought to achieve these effects by increasing the rate at which energy sources are broken down and improving the efficiency of enzymes involved in the fat burning process. Caffeine has also been associated with the appetite in the past and there has been some suggestion that the ingredient can increase satiety and prevent cravings.

Other sources have also suggested that the chlorogenic acid in green coffee beans can induce weight loss by the process of carbohydrate blocking. It is thought that this substance can block the enzymes involved in the breakdown of carbohydrates, meaning that the molecules consumed in meals remain too large to pass through the digestive tract into the body. As such, the carbohydrates are thought to be excreted from the body without contributing extra calories.

Oriental Water Plantain

Oriental water plantain is a herbal ingredient that is commonly found in traditional Chinese medicines but is not well-known in the weight loss market. The ingredient is rarely added to weight loss supplements, though there has been some suggestion that it might be able to help with weight-related problems such as high cholesterol in the past. Oriental water plantain has been said to act as a diuretic; the ingredient might, therefore, cause weight loss in the short term due to reduced water weight. This weight will, however, be due to increased urination rather than fat loss. Overall, there is very little reliable information on the potential weight loss effects of this ingredient.


Amylum, more commonly listed as medical amylum, is rarely used in weight loss supplements. Amylum is a more technical term for starch – a form of carbohydrate. Though not made clear, it seems as though this ingredient has been added to this weight loss supplement for its claimed effects as an appetite suppressant. Unreliable sources have stated that, when combined with water (as is the case in the stomach), amylum expands in size. It is said to work in a similar way to fibre, helping the digestive tract to feel fuller for longer. By expanding in the stomach, amylum supposedly prevents cravings and increases feelings of satiety.

Cassia Seed Extracts

Cassia seed extract is also an ingredient that can be found in traditional Chinese herbal medicines, but is not all that common to weight loss supplements. This ingredient is believed to act as a laxative and diuretic. As with oriental water plantain, cassia seed extract might therefore, give the user an illusion of weight loss. The number of the scales might go down with the consumption of cassia seed extract, but this is likely to be because you are losing water from your body rather than fat; the effect will therefore only be temporary.

Job’s Tears Extracts

There is little suggestion that job’s tears extract might actually help to increase weight loss. The ingrediet has been associated with improvements in parameters associated with body weight, such as cholesterol and blood lipid levels. These potential effects might be beneficial to the general health of those who are looking to lose weight, but are unlikely to have any direct effect on body weight or fat levels.

Key SlimVits Ingredients

molecular 538

It is not made entirely clear on the official website what ingredients are present in SlimVits. Under the FAQ ‘what ingredients can be found in SlimVits?’ five ingredients are listed. It is stated that green coffee extract is the main ingredient in the product, which, so it says, should help to suppress the appetite and increase the metabolism. A full ingredients list is not provided and no ingredient quantities are listed. Some of the ingredients have an associated with weight loss, but none have been proven to be effective weight loss aids.

Active Ingredients

Green Coffee Extract

Green coffee extract is an active ingredient that is taken from the bean of the coffee plant. In its raw state, coffee beans are green in colour – hence the ingredient name. Green coffee beans are said to be high in chologenic acid – a compound that is believed to have an array of health benefits. The ingredient has been said to be beneficial for the treatment of conditions like high blood pressure, bacterial infections, diabetes, and Alzheimer’s disease, as well as obesity.

Oriental Water Plantain

Oriental water plantain is the name of a plant that is often used in traditional Chinese medicines. It is the root of the plant that is thought to have medicinal properties and as such, this is where the extract is usually taken from. There is very little information available regarding the oriental water plantain, but its extract has been used in the past for the treatment of bladders and urinary tract conditions. There has been suggestion that the ingredient can act as a diuretic.


Amylum is more commonly known as starch – a large number of glucose molecules joined together to form a carbohydrate. Starch is present in most green plants and is commonly consumed in the human diet. There is suggestion that starch consumption might help with weight loss because medical amylium might expand in the stomach upon contact with water, causing the ingredient to swell and better fill the space in the stomach. This reaction is thought to help to suppress the appetite.

Cassia Seed Extracts

Precisely what this ingredient is, is unclear. Cassia is the name of a genus of plants that once included senna. Accordingly, some traditional medicines that include cassia in their ingredients list are actually referring to extract taken from senna plants. Cassia and senna are both believed to have laxative properties, though senna is better studied than cassia. Cassia is thought to have the potential to reduce cholesterol and blood lipid levels, but evidence in support of these claims is very weak.

Job’s Tears Extracts

Job’s tears refers to a type of grass that is native to parts of Asia. It its seeds that give this plant its name, since they are described as tear-shaped. Extract from the seeds has been used in traditional Asian medicine for the treatment of a range of conditions. Some examples include: respiratory tract infections, cancer, high cholesterol, arthritis, warts, and hayfever, amongst others. It is believed to have an antioxidant effect that can improve general health, though scientific evidence in support of its health claims is largely lacking.

Clinical Studies

Clinical Researcher 538

There is no mention on the official product website of any clinical studies that have been performed on SlimVits; a review of the literature does not reveal any scientific studies that have been performed on a product of this name. Only one of the ingredients in SlimVits, green coffee bean extract, has been subject to any clinical study, the others have not been tested at all for any potential weight loss effects.

A clinical trial is a study performed by scientists to test a hypothesis with regards to a substance or product. Clinical studies are undertaken under controlled conditions, usually using a treatment group and a placebo group to ensure that results are as reliable as possible.

Clinical Studies On Each Ingredient

Clinical Studies on Green Coffee Extract

In contrast to all of the other ingredients mentioned on the official SlimVits website, green coffee extract (which is stated as the key ingredient in the product) has been subject to a number of clinical studies with regards to its potential weight loss effects. It is important to note however, that most of these studies are of poor quality and so no firm conclusions can be drawn yet. It is also difficult to compare the results of these studies to any potential effects of SlimVits since there is no mention of how much green coffee extract is present in the supplement.

The majority of studies on green coffee extract to date have been undertaken using animal subjects. One such trial was published in 2006. This study tested the effects of green coffee bean extract on fat and body weight gain using mice as subejcts. The mice were given a standardised diet supplemented with green coffee bean extract, including chlorogenic acid and caffeine, for a test period of two weeks. A number of measurements were taken throughout the study to check fat absorption, fat gain and body weight gain.

At 0.5 and 1%, green coffee bean extract was found to reduce fat content and body weight. The results suggested that caffeine and chlorogenic acid might help to reduce there measurements. At 100mg/kg and 200mg/kg per day for 13 days, green coffee bean extract was also seen to reduce triglyceride levels. The authors therefore concluded that the ingredient might be beneficial for the prevention of weight and fat gain, and that these effects are achieved through preventing fat absorption and triggering the breakdown of fats in the liver.

A second animal study was published in the Asian Pacific Journal of Tropical Medicine in 2016. As with the previous study, mice were used in this trial to investigate the effects of green coffee bean extract on obesity-related parameters. The mice in this study were obese due to the administration of a high-fat diet for four weeks. The subjects were then divided to receive either a high fat diet on its own, or a high fat diet with different quantities of green coffee bean extract (50, 100, or 200mg/kg). Measurements were taken to look at fatty acid synthesis and body fat levels throughout.

The results suggested that green coffee bean extract treatment, when taken by obese mice, could reduce body weight gain and fat mass. It was also noted that the ingredient could help with the regulation of hormones involved in fat breakdown. It was concluded from this investigation that green coffee bean extract might be useful as an anti-obesity agent. It seemed to have an impact on decreasing the accumulation of body fat through the control of the creation of new fat cells and genes associated with fat metabolism.

A 2014 study was undertaken to test whether or not decaffeinated green coffee bean extract could help to prevent obesity and related factors. This study also involved mice as subjects; the mice were in the case split into six different groups. The first group received a chow diet, the second a high fat diet, and the other four a high fat diet with 0.1%, 0.3% or 0.9% decaffeinated green coffee bean extract, or 0.15% chlorogenic acid. The authors reported that at doses of 0.3% or higher, green coffee bean extract had the potential to reduce body weight gain caused by a high fat diet. It was also noted that the green coffee bean extract seemed to prevent increases in insulin resistance.

One study could be found that looked at the impacts of green coffee bean extract on body weight and associated parameters using human subjects. Twleve healthy volunteers took part in this clinical study. The participants were given different coffee products with glucose. It is reported that instant coffee supplemented with chlorogenic acid (found in green coffee bean extract) helped to reduce glucose absorption significantly compared to a control. These effects were not however, documented for the normal or decaffeinated instant coffee. For a second arm of the same study, thirty overweight study participants took part in a 12-week randomised, double-blind trial. Here, volunteers were given instant coffee with chlorogenic acid or instant coffee without chlorogenic acid. Results suggested that the addition of chlorogenic acid could significantly aid weight loss.

Finally, a group of authors undertook a systematic review and meta-analysis on the topic of green coffee bean extract for weight loss. Without any restrictions on time or language, the authors searched all relevant scientific literature databases for studies that tested the effects of green coffee bean extract on weight loss using human subjects. Five trial were uncovered, three of which were utilised in the analysis. It was made clear however, that all trials had a high risk of bias, so the results could not been deemed entirely reliable. When the results of these trials were combined and statistically tested, a significant difference could be seen in the effects of green coffee bean extract when compared to a placebo. It was concluded that whilst the results may seem positive, all of the trials were poor quality and so more reliable studies are required before a conclusion can be drawn with regards to the potential of green coffee bean extract in weight loss.

SlimVits Side Effects

Woman With Stomach Ache  538

The official website does not list any potential side effects associated with the SlimVits supplement. In fact, in the FAQ section of the website, it is stated that SlimVits is created using natural ingredients that do not cause side effects. This statement simply is not true; just because an ingredient is natural does not mean that it is safe for consumption and will not cause side effects; there are side effects associated with every one of the listed ingredients in SlimVits, some of which are severe. It is mentioned on the SlimVits website that if you have any concerns, you should talk to a doctor before taking the product.

Side Effects Associated With Each Ingredient

Side Effects associated with Green Coffee Extract

Green coffee beans are thought to be ‘possibly safe’ for consumption in doses up to 480mg per day for a period of 12 weeks. The longer term effects of green coffee extract are not known, nor are those of larger doses. Precisely how much green coffee extract is present in SlimVits is not disclosed and, as such, its safety and potential side effects cannot be stated with any certainty.

Green coffee contains caffeine and as such, can cause related side effects. Caffeine-related side effects include, for example, increased heart and breathing rate, difficulty sleeping, headaches, nausea, stomach upset, nervousness, anxiety, and ringing in the ears. We would recommend avoiding this ingredient if you are pregnant, breastfeeding, or under the age of 18. If you have any pre-existing health condition, particularly associated with the cardiovascular, digestive, or respiratory systems, or if you have a history of mental illness, you should consult a doctor before taking green coffee bean extract.

Side Effects associated with Oriental Water Plantain

Little is known about the safety of oriental water plantain extract as an ingredient in traditional medicines and as such, potential side effects associated with this ingredient are not well documented. The plant itself is thought to be toxic, and so unsafe for consumption; the roots can be poisonous and so should not be consumed in the fresh form. Extract of the oriental water planatain that is used in traditional medicines and supplements has not been well studied; in consequence, we would recommend that you avoid this ingredient if you are pregnant, breastfeeding, or under the age of 18. Be sure to consult a doctor before taking oriental water plantain if you have any pre-existing health conditions.

Side Effects associated with Amylum

We were unable to find any reliable sources that have documented the possible side effects associated with consuming too my stach (amylum). Since it is present in most green plants (many of which we consume in our everyday diets), starch is unlikely to cause side effects when consumed in sensible amounts. Again, the quantity of amylium present in SlimVits is not disclosed and so we cannot state with any level of certainty that the ingredient will not cause side effects. Consuming much more starch than your body is used to could potentially cause side effects. We would recommend that you consult a doctor before taking this ingredient, particularly if you are pregnant, breastfeeding, or have any pre-existing health conditions.

Side Effects associated with Cassia Seed Extracts

It is not entirely clear what ingredient is being referred to by ‘cassia seed extracts’. There are numerous plants that belong to the Cassia genus and many more that used to belong in that group, but have since been moved to another genus – Senna. Not enough is known about the effects of cassia consumption on health to be able to list potential side effects associated with these plants; as such, it is recommended that pregnant and breastfeeding women avoid taking the ingredient. Senna has been better studied and so has a list of related side effects. Senna is thought to be safe for consumption in the short term, but can still cause side effects such as stomach cramps, diarrhoea, and digestive discomfort. In the long term, senna might not be safe. This is because the ingredient has a laxative effect and if used continually for a longer period of time, the body can become dependent on its laxative properties, potentially causing serious side effects. Avoid this ingredient if you have gastrointestinal or cardiovascular conditions, or if you have electrolye disturbances or deficiencies.

Side Effects associated with Job’s Tears Extracts

Although believed to be safe when consumed as a food, the safety of Job’s tears extracts is not known. Not enough studies have been performed on the ingredient to determine a list of potential side effects. Due to the lack of information available on the ingredient, we would recommend that all potential customers consult a doctor before taking the ingredient and avoid it entirely if they are pregnant or breastfeeding.

How To Use

Woman With Pills 538

Not much information is available on the official SlimVits website with regards to how the product should be used. It is stated that ‘depending on your preferences, you should take 1 capsules per day before 9am’. No other option is given – rendering the ‘depending on your preferences’ phrase meaningless. In a different part of the website, it is stated that the capsule should be taken with breakfast and a large glass of water. It is added here that the consumer should take Sunday off every week (or pick one day of your choice) to allow the body to ‘reset’ and prevent it from getting used to the supplement.

There is a disclaimer at the bottom of the webpage stating that statements made on the website have not been evaluated by the FDA and noting that the product is not intended to prevent, treat, or cure, any disease. It is stated that the product will not cause any side effects, but that if you are worried, that you should consult a doctor before taking the supplement.

Based on the lack of knowledge about the ingredients in the product, we would recommend that all users consult a doctor before taking this supplement, particularly if you have any pre-existing health condition. Do not take SlimVits if you are pregnant, breastfeeding, have a digestive, cardiovascular or cerebrovascular condition, have hyperthyroidism, liver or kidney problems, glaucoma, hyperplasia, or psychosis. Also avoid if you are addicted to any drugs, medicines, or alcohol, or are under 18 or over 60.

Who Makes It

Very little information is provided on the official product website with regards to who makes the product. A name for the manufacturer is not disclosed. It is assumed that the company behind the product is called SlimVits. Contact details for the retailer or the manufacturer are lacking; there is no email address or phone number – only an online form for customers to fill in. A full postal address is provided for the factory that the supplement in produced in, which is based in Yunnan, China. This factory is claimed to adhere to Good Manufacturing Practice standards.

The company does not appear to make any products. No other supplements are available for sale on the official SlimVits website. There are lots of spelling and grammatical errors on the official website. The company makes numerous unbacked statements, some of which are simply incorrect (for example, that the product will not cause any side effects).

No prices are provided on the website. In order to check out with an order and look at product costs and shipping costs, the customer must sign up to the website with an email address. There does not appear to be any money-back guarantee or multi-buy offers available via the official website.

Where To Buy SlimVits


SlimVits capsules are available from the official website, from Amazon, and from an online store called Watermans.

We do not know if this option is cheaper than the official website since product prices are not disclosed on the SlimVits site.

Watermans – an online company that seems to sell a small selection of health products – sells one capsule of SlimVits for £24.99.

Overall Verdict

This product is claimed to target several different areas of weight loss quickly and efficiently. It has its own dedicated website with an FAQ section, where a list of people who shouldn’t take the product can be found. Overall, the website does however lack a lot of important information. A full ingredients list is not available and there is no mention of ingredient quantities; it is also stated that the product will not cause side effects, which simply is not true. Company contact details are not available and the product price is not disclosed until the customer signs up to the website. There is some, limited, clinical evidence in support of the key ingredient (green coffee extract), but none of the other ingredients have been tested for their potential weight loss effects and some might cause unknown side effects.
