How Hiprolean X-S Works

woman wondering how diet pill works 538

Hiprolean X-S aims to bring about three effects: fat burning, metabolism boosting and appetite suppression. Unfortunately, we are not entirely clear as to how these are achieved owing to the absence of an official website. The manufacturers have not provided us with an extensive level of information pertaining to how these processes translate into biological changes within the body, and how these changes are translated into weight loss.

It is plausible however to get an idea of how the product is supposed to work based on the ingredients in Hiprolean X-S. For instance, green tea is thought to be capable of encouraging fat burning and caffeine is thought to be effective at metabolism boosting. The same can be said about raspberry ketones. Finally, we have appetite suppression; it is unclear how the product targets this area. While raspberry ketones have been associated with appetite suppression, they are not known for being exceptionally capable in this regard.

Green Tea

Green tea is one of the most popular ingredients in weight loss supplements and has been used for centuries for this purpose. This is owing to several reasons. One of these is because green tea is known to contain a considerably large amount of antioxidants. Antioxidants are thought to be useful chemicals because they might allow for thermogenesis to take place. Thermogenesis is the process whereby energy is generated. This energy can in theory be subsequently utilized for purposes of boosting the metabolic rate of reactions taking place within the body. Secondly, an increase in metabolic rate might also result in increasing the rate of reactions that are associated with the burning of fat.


Let us look at caffeine now. Caffeine is essentially associated with two features. The first of these is appetite suppression. It is believed that intake of caffeine results in prolonging of hunger. However, it is not clear as to how effective and how prolonged this is. The second feature that caffeine is associated with thermogenesis. It is believed to be capable of supplying heat, which might subsequently cause increases in fat burning and the metabolic rate.

Key Hiprolean X-S Ingredients


Raspberry Ketone

Raspberry Ketoneis contained in berries, and is responsible for the strong aroma associated with them. It is a chemical compound in nature. It is believed to increase levels of a hormone called adiponectin. Adiponectin is pivotal because it is believed to regulate both the levels of metabolism in the body as well as the rate of lipolysis – the process of breakdown of fats within the body. The concentration of this particular hormone hence is thought to have an effect on the rate of metabolic reactions within the body. They are also associated with the process of fat burning. It is believed that the decrease in the concentration of this particular hormone is associated with weight gain. Hence raspberry ketone supposedly plays a pivotal role by supplying this particular hormone and ensuring substantial levels of it within the body.

Green Tea

Green tea has been used as a weight loss agent for centuries. The antioxidants in green tea are popularly associated with two particular functions within green tea. Firstly, they are thought to result in the process of thermogenesis. This is the process whereby energy is created within the body as heat, and it might allow for higher rates of metabolism to be achieved. This is because this energy can be subsequently utilized for purposes of metabolism boosting. Owing to this process, energy is thought to be released, allowing for a heightened metabolic rate. This synthesis of energy is subsequently said to result in the burning of fat at high rates, too.

Vitamin B6

Vitamin B6 is an essential member of the B complex family. It is chemically known as pyridoxine. It is water soluble in nature. Vitamin B6 is believed to be useful because it supposedly allows for spurring of metabolic processes within the body. The nutrient is said to be capable of stimulating around 100 different enzymes within the body. The regulation of these enzymes plays a pivotal part in both processes: fat burning and metabolism boosting. Other than that, Vitamin B6 is also thought to target glycogen. Glycogen is a form in which carbohydrates are stored. Hence, a consistent supply of Vitamin B6 is said to allow for conversion of carbohydrates into glycogen; this glycogen is in turn is converted into energy thus allowing the maintenance of the metabolic rates within the body.

Clinical Studies

Clinical Researcher 538

Although we were unable to come across an official website for this particular weight loss supplement, we are quite certain that it does not have clinical validity as a product. This is because we found no mention of it in the scientific literature. In such a situation, we turn to individual ingredients and see if they have clinical validity associated with them.

Green Tea

We were able to come across several different studies for green tea. One set of studies that we came across was conducted for a period of 12 to 13 weeks in Japan. The purpose of doing so was to determine whether intake of green tea can positively influence weight loss. When the results came out, they demonstrated a range of weight loss from 0.2 kg to 3.5 kg. The second set of studies that we came across was conducted outside Japan for around the same duration. The results of this set of studies demonstrated difference of a mean weight loss of 0.04 kg.

Raspberry Ketone

For this particular ingredient, we came across a study that was conducted to investigate the effects of raspberry ketone on obesity. It used mice as participants. These mice were first provided a high fat diet with raspberry ketone in concentrations of 0.5, 1, or 2% for a period of 10 weeks. They were then administered the same diet for another 5 weeks, but this time with concentrations of 1% of raspberry ketones. When the results came out, they demonstrated that the intake of raspberry ketone led to a substantial decrease in the accumulation of fat within the body. Moreover, intake of raspberry ketone resulted in a decrease of triacylglycerol content. Other than that, it was also believed to result in a decrease in the rate of lipolysis associated with the change of lipase into lipid droplets within the fat cells. However, while this study provides us with positive results in terms of the effects of raspberry ketones on weight loss and weight management, it needs to be kept in mind that it was conducted on mice. Therefore, we have to be careful about drawing conclusions because it is not necessary that the results obtained from a study on mice might be applicable to humans in the same way.

Vitamin B6

Lastly, we have Vitamin B6. To determine the effectiveness of this particular ingredient, we were able to come across a double blind and placebo controlled study. It lasted for a total duration of 24 weeks and involved 20 participants. The purpose was to determine the relationship between the intake of pyridoxine and corresponding weight loss. The results of the study demonstrated that intake of Vitamin B6 caused an average fat loss of 1.12 kg and 1.82 kg at 12 weeks and 24 weeks respectively. Therefore, intake of Vitamin B6 was positively associated with fat loss tendencies.

Hiprolean X-S Side Effects

Woman With Stomach Ache 538

This particular weight loss supplement is associated with several side effects. It contains several ingredients that are capable of manifesting side effects. For instance, it can cause anxiety, nervousness and tremors. It is also associated with headaches and with sleeping disorders along the lines of insomnia. Raspberry ketones are chemically similar to another chemical known as synephrine and so there is some concern that they might be capable of exhibiting side effects associated with synephrine. Notable amongst these are jitteriness, and rises in blood pressure and heartbeat.

Green Tea and Caffeine

It is useful to discuss these two ingredients together because green tea contains caffeine, and hence both of them manifest the same side effects. First of all, caffeine is capable of causing side effects along the lines of nervousness, anxiety and tremors. It can also cause headaches as well as ringing in the ears. Other than that, it is quite popularly associated with sleep disorders, the most noticeable amongst which is insomnia. Lastly, caffeine can also cause rapid rises in heartbeat and blood pressure.

Raspberry Ketone

The issue with raspberry ketone is that it is chemically similar to another chemical known as synephrine. Hence, it might be capable of causing side effects associated with synephrine, though these have not yet been reported for raspberry ketones. Synephrine is associated with high blood pressure, fainting, strokes as well as increased likelihood of a heart attack. It is also associated with headaches along the lines of migraine and cluster headaches. Other than that, it can aggravate the condition of glaucoma and so must be avoided by those suffering from the condition. Lastly, synephrine is a stimulant and hence must be avoided before a surgery. This is because synephrine acts to increase the heartbeat and blood pressure and this can be troublesome before a surgery.

Vitamin B6

Lastly, we have Vitamin B6. This demonstrates side effects that are similar to caffeine. For instance, it can cause vomiting, nausea, stomach pain and loss of appetite. It is also associated with tingling and sleepiness. Last of all, exceptionally large doses of this particular ingredient can result in brain and nerve problems.
