Slimquick Review (New 2020) – Is Slimquick Effective? The Final, Science-Backed Answer!


  Slimquick is a weight management supplement that is tailored specifically to females. Using slimquick in conjunction with a calorie restricted diet is advertised to increase weight loss by three times more than if you were undertaking the diet alone.

Slimquick is a simple tablet that is taken 3 times daily over a 13 week period. It differs somewhat from more traditional weight management products in that it is too be combined with a diet consisting of only 1350 calories per day. This is said to provide the optimal conditions for female weight loss. It has been reported that those supplementing with slimquick have an average weight loss of 25 pounds over the 13 week period – implying that losing weight at a rate of almost 2 pounds per week is entirely feasible when using this supplement.

This product is advertised to use highly potent, yet all natural ingredients. These ingredients are said to speed up the consumer’s metabolism, improving their ability to burn fat. Moreover, these ingredients are suggested to positively influence hormone levels, reduce appetite, and improve energy levels.

To determine whether Slimquick does indeed meet these claims, we are going to take an in depth look at the ingredients included within the product, and the way in which they interact with the body. This will allow us to determine whether this product does indeed help promote weight loss, or whether it is (ultimately) a waste of money.

Slimquick Ingredients

The first thing worth mentioning is that there is a quite a large number of ingredients within the Slimquick formula. While this may not always be a bad thing, it does suggest that each ingredient is provided in somewhat small doses. This may lead to the reduced effectiveness of a given ingredient.

Additionally, the amount of each ingredient is not actually stated on the products label. This makes it difficult to determine whether the ingredients are provided in effective doses, or used merely as a ‘filler’.

Nonetheless, it is important to take an in depth look at the key ingredients within this formula to determine its effectiveness, and any potential side effects that may be associated.

Green Tea Extract

Green tea extract is an incredibly popular ingredient that occurs frequently within weight management products.

The supplementation of Green tea has been shown to influence fat loss through two key mechanisms. Firstly, it increases the rate at which fat is broken down and used for energy, and secondly, it causes an increase in the metabolic rate of the body [1].

By influencing these two factors, green tea extract promotes fat lass by increasing the amount of energy we use to function AND increasing the amount of that energy that comes from fat [1]. This may contribute to an increase in fat loss over time, suggesting a valuable inclusion to a supplement of this nature.


Similarly to green tea extracts, caffeine is an ingredient that appears frequently within supplements of this nature, suggested to have a host of benefits to those trying to lose weight.  It is common knowledge that caffeine acts as an effective stimulant, but what is less commonly know is that it can also improve the body’s ability to metabolise fat for energy.

When caffeine is consumed, it is absorbed through the digestive system and transported into the blood and liver. Once in the liver it is broken down into compounds and transported to the neural tissue of the brain. It is at this point that caffeine causes stimulation of the brain and central nervous system.

This stimulation is known to reduce sensations of fatigue, while also increasing our energy levels and feeling of alertness. This stimulation of the nervous system also acts on the physical processes of the body directly, where caffeine consumption has been shown to increase metabolic rate by up to 11%, while also increasing the rate at which the body breaks down fat for energy by up to 13% [2].

The compounded influence of these two mechanisms is likely to contribute to an increased rate of weight loss over time (with a good portion of that coming from fat directly). It is important to note that caffeine is a stimulant, and there may be some side effects associated when consumed in high dosages.

Rhodiola extract

Rhodiola is a particular herb that was frequently used in traditional eastern medicine as a way to stave off fatigue.

Recent research has supported this suggestion, demonstrating that the consumption of Rhodiola extract can cause significant reductions in the sensations of physical exhaustion and stress experienced after undertaking physical exercise, while also improving cognitive function and mood [3].

By reducing symptoms of fatigue and improving mood and mental clarity, Rhodiola extract could have merit in a weight loss supplement of this nature, as it can reduce the feelings of lethargy and mental ‘fogginess’ associated with times of calorie restriction (such as that recommended in conjunction with the supplementation of slimquick).

Capsicum Extract

Capsicum extract comes from the Capsicum plant (commonly known as red peppers here in the USA), which is a proud member of the nightshade family.

The consumption of Capsicum has been shown to stimulate the nervous system through specific receptors found in the mouth and digestive tract. This stimulation has been demonstrated to cause small increases in the secretion of epinephrine, which in turn can lead to increases in metabolic rate and appetite suppression [4].

Additionally, this same stimulation has been suggested to increase the breakdown of fats for energy [4], suggesting that the supplementation of capsicum extract may promote fat loss though an increase in fat metabolism AND an increase in metabolism.


L-Tyrosine is an essential amino acid that is used in the production of the hormones noradrenaline and dopamine, which are both linked to mood. It was thought that by supplementing with L-Tyrosine we could reduce the feelings of stress associated with dieting and exercise, while also improving feelings of wellbeing.

Unfortunately the supplementation of L-Tyrosine has only shown to have minor effects in this manner, causing very small increases in feelings of wellbeing and minor reductions in stress [5].

The limited effectiveness of L-tyrosine in humans suggests it may have little merit in weight management supplements.

Ginger Extract

Ginger is a spice that is frequently used in household cooking. Interestingly, it is one of the few common spices that has been shown to have positive effects on the human body, particularly in regards to general health and function.

Ginger is full of compounds that have been shown to have anti-inflammatory effect on the cells of the human body. By reducing cellular inflammation, ginger can improve the function of our cells. This can further increase the body’s ability to use stored energy (with a particular emphasis on fat).

As an added bonus, the supplementation of ginger has also shown to suppress appetite. This can lead to a reduced energy intake during the day, which can promote further fat loss over time [6].

Turmeric Extract

Similar to ginger, Turmeric is a spice commonly used in curries. Turmeric contains key bioactive compounds known as Curcumin and Curcuminoids, each of which have shown to influence the human body positively.

In regards to weight loss, there has been limited support for the use of Curcumin, although it has demonstrated a number of anti-inflammatory and anti-diabetic effects. The supplementation of Curcumin has shown to improve insulin sensitivity and recue insulin resistance, which can lead to an improved ability to manage blood glucose levels [7].

By improving the body’s ability to manage blood glucose and insulin levels, it may lead to improved weight management and weight loss in overweight and obese individuals, although further research is needed.

Trace Ingredients

Slimquick also contains the extracts of a number of herbs and spices that have been suggested to promote weight loss through a number of mechanisms.

Despite this, there is limited evidence to support the inclusion of these ingredients as weight management supplements, which leads to suspicion that they were included as ‘filler’ ingredients due to their low price point and easily accessibility.

Ingredient Summary

Slimquick does actually contain a host of ingredients that have been shown to have a number of positive effects on the human body, including stimulating increases in metabolic rate and fat metabolism, combined with improvements in mood, and reductions in appetite and sensations of fatigue.

Unfortunately, it also includes a huge number of ingredients that have shown to have little to no effect on weight loss. The inclusion of these ingredients leads to the suggestion that they are merely in the formula to bring down its production cost, subsequently reducing the amount of effective (and more expensive) ingredients included within the formula.

This suggestion is further supported by the fact that Slimquick do not provide the measured amount of each ingredient within the formula, making it difficult to identify whether the dosage of a particular ingredient is effective or not.


In conclusion it is extremely difficult to recommend Slimquick as a weight loss supplement. The limited clarity in which the product is described makes it very difficult to establish whether the product will have any effect on weight loss, or is merely a waste of money.

Moreover, while some ingredients have shown to have positive effects on weight loss, too many have no research to support their claims. And I would expect that for those who do actually experience weight loss using the Slimquick protocol, it could be put down to the 1350 calorie diet, and not the supplement itself.
