Devorcal Review

Made famous by the popular health supplement and diet company Dukan Diet, Devorcal is said to be able to help its users reach their weight loss goals quickly, safely and effectively. Evidence to back up these claims is however not available.

Claimed weight loss benefits

Dukan Diet, the company behind Devorcal, claim that their product is able to work as a fat burner and appetite suppressant; it therefore is said to target two of the five key areas of weight loss.

How Devorcal Works


Devorcal is a supplement described by its manufacturers as being a highly effective calorie burner that targets both proteins and fats. Devorcal is also said to work by suppressing appetite due to its key ingredient, meaning that you are less likely to overeat, while also breaking down proteins and fats, resulting in weight loss. The supplement is to be taken during meals in order to aid digestion and work most effectively, and should be taken for 3 months to ensure that you are able to maintain your weight loss results.


The active ingredient in Devorcal is Acigrine, which is also known as the dry extract of apple cider vinegar. Apples are a good source of pectin, a substance that might be able to make you feel fuller and satisfied for a longer period of time, suppressing feelings of hunger and making you less likely to overeat. Pectin supposedly works by forming a gelatinous mass when it enters your stomach, leaving you feeling full. This is purportedly due to it being a soluble fibre that absorbs water, and this mass is said to travel through the stomach and small intestine undigested. Pectin might also slow gastric emptying, meaning that food takes longer to leave the stomach and enter the small intestine, potentially keeping you feeling fuller for longer.

Generally, acids are able to help with the digestion of protein. By increasing the amount of acid in the stomach before or during a meal, you might increase the availability of protein for hormone synthesis. As it is said to stimulate digestion, apple cider vinegar might also able to reduce the amount of time that fat stays in the digestive tract. If this substance remains in the system longer than is necessary, apparently the body will absorb more and this can lead to a gain in weight. As apple cider vinegar supposedly moves the fat through the tract quickly, it is said to prevent this from happening.

Key Devorcal Ingredients

molecular 538


The active ingredient within Devorcal is Acigrine, which is also known as apple cider vinegar. Apples contain a substance named pectin, which is believed to be able to create feelings of fullness, suppressing hunger and making you less likely to overeat. It is said to work thanks to the fact that it is a soluble fibre and forms a mass within the stomach that can supposedly travel through the small intestine without being digested. Pectin might also trigger stretch receptors, which send messages to the brain, releasing hormones to extend the sense of satiety. Gastric emptying is also thought to be slowed by pectin, meaning that food takes longer to leave the stomach, leaving you feeling satisfied for longer periods of time.

Apple cider vinegar is also claimed to be able to help with the digestion of protein, increasing the availability of the substance for hormone synthesis. By stimulating digestion, Acigrine is said to to reduce the amount of time that fat stays in the digestive tract meaning that the body is less likely to absorb it – preventing weight gain.

Clinical Studies

Clinical Researcher 538

Clinical studies are conducted on health supplements in order to establish that they are safe and effective enough to be used by consumers. However, the health supplement market is unregulated meaning that it is possible for products that have not been tested to reach shelves. There does not appear to be any evidence of any clinical testing on the effectiveness of Devorcal on the Dukan Diet website, and there is limited evidence of clinical studies on the active ingredient’s effectiveness on weight loss. It is important that clinical testing is carried out on a supplement to ensure that it is safe to use and also to make sure that the ingredients within it will work effectively together and will not react poorly with each other.


Apple cider vinegar is said to work to aid weight loss, but there has not been any clinical research into its ability to aid weight loss. One test was carried out on white vinegar, which is chemically similar to apple cider vinegar. The study was carried out in 2005 on 12 people. Half of the group were given a piece of bread with white vinegar and the other half were given a plain piece of bread. The study found that most of the people given the vinegar and bread felt fuller for longer than those who just ate the bread. These results suggest that apple cider vinegar does have the potential to suppress appetite, however the study only used a small number of subjects meaning that the results may not be reliable enough to prove the substance’s ability to aid weight loss.

Devorcal Side Effects

Although there is no mention of any side effects on the Devorcal web page, this does not mean that the product does not carry any. Unfortunately, there is a lack of customer reviews and clinical studies to provide information as to first hand experiences of side effects, however there are some known side effects to the product’s key ingredient Acigrine, or apple cider vinegar. The Devorcal web page does state that children and pregnant and breast feeding women should not use the product


Consuming large amounts of this substance can lead to side effects. Your potassium levels becoming low and this can result in uncomfortable side effects in the muscles and nerves as well as frequent urination, cramps, nausea, diarrhoea, dehydration, confusion and changes in heart rate. Due to the acidity of the substance, users can also expect to potentially experience stomach irritation and a sore throat. To avoid these side effects, users should ensure that they do not take the product on an empty stomach and they should consume the capsule with a glass of water to reduce irritation in the mouth.

How to Use

Woman With Pills 538

Devorcal is a product from Dukan Diets’ ‘attack’ phase and Dukan recommend that the supplement be taken during a meal – not before or after one as it supposedly works most efficiently when digestion is taking place. During the slimming phase, users are advised to take 2 capsules at the start of each meal for at least one month, although three months are recommended. During the weight stabilisation period, users should take 2 Devorcal capsules in the event of over excessive eating or in to neutralise any rich, fatty, sweet or calorific meals. Devorcal is described by its manufacturers as a 37 day treatment to be repeated as required. These instructions are clear and offer a good amount of detail to users, however it is not noted how long users should leave in between taking each capsule.

The Devorcal web page states that women who are pregnant or breastfeeding should not use the product and neither should people under the age of 18 as the supplement is not suitable for children to use. Furthermore, those who suffer from pre existing medical conditions, who are currently taking prescribed medication or who are generally worried or concerned about their health should speak with their doctor before beginning to use Devorcal. It is believed that Acigrine, the active ingredient within Devorcal can react with certain medical conditions such as diabetes and so people with this condition should take extra care as their medication may need to be altered while using this supplement.
