Nicht alle Inhaltsstoffe in Fettverbrennungsmitteln müssen immer synthetisch sein. Beispiele hierfür sind Curcumin, das aus der beliebten Curry-Gewürzmischung bekannt ist, oder sogar Zimt. Ohne Zweifel kann Synephrin zu der Gruppe der natürlichen Thermogenen hinzugefügt werden – ein wirksamer Bestandteil im Kampf gegen Übergewicht.
What is synephrine?
Synephrine is a chemical compound found in citrus fruits, particularly bitter orange. It belongs to the group of alkaloids and has similar effects to other sympathetic substances such as adrenaline. Synephrine affects the sympathetic part of the nervous system and can cause similar reactions, such as increased heart rate and blood pressure. However, unlike ephedrine, synephrine exhibits a more moderate stimulating effect, meaning that it does not cause such intense stimulation. As a result, synephrine can be beneficial in reducing fat tissue through increased lipolysis and thermogenesis. Synephrine can also help control appetite and suppress uncontrolled hunger attacks. Additionally, bitter orange contains natural detoxifying and cleansing properties, which can be beneficial for individuals who do not lead a healthy lifestyle.
Application of a bitter orange extract
Understanding the mechanism of action of synephrine allows for an easy determination of its purpose. Bitter orange extract is primarily used in processes related to weight loss and fat reduction. The thermogenesis mechanism involves raising body temperature and increasing potency, which is undoubtedly beneficial for people struggling with obesity. Lipolysis, as the name suggests, leads to the breakdown of fat cells and a significant reduction in their size. This makes it easier for the body to get rid of unwanted fat and improves the process of shaping the figure. However, synephrine is not only used for weight reduction. It can also be used, like ephedrine, in the treatment of colds and their symptoms. It can also be used in the case of asthma attacks, as supplementation with synephrine contributes to the expansion of the bronchi. Synephrine can also be used in cases of digestive problems. Thanks to the stimulation of digestive processes, including the work of the intestines, it is often recommended for constipation and digestive disorders. On the other hand, the suppression of excessive hunger is often recommended in cases of nausea. The mobilizing and stimulating nature of synephrine makes it a popular component of sports supplements. Bitter orange extract is often a component not only of fat burners but also of pre-workout and creatine supplements. This makes synephrine a popular remedy for chronic fatigue.
From which sources can synephrine be sourced and how to properly dose this substance?
Synephrine is primarily sourced from the widely recognized, bitter orange variety. It can often be found under the names sour orange, neroli or chongocaoto. This type of citrus is not common in our country and occurs mainly in the regions of Southeast Asia. In practice, not only fruits but also flowers, leaves, and juices from this plant are used. In the case of dosing, the matter is agreed upon, and most scientific sources provide different amounts to be taken. On average, the daily dose should range from 7 to 30 mg of this substance. It is important to remember that the standalone use of synephrine will not bring the expected results. The extract from bitter oranges should be considered only as a supplement to diet and exercise, which form the foundation for effective and healthy fat tissue reduction.
Contraindications
The use of synephrine, due to its stimulating effect, is not recommended for all individuals, especially those suffering from cardiovascular diseases. The extract from bitter orange, which contains synephrine, can cause an increase in blood pressure and heart rate, making it absolutely contraindicated for people with arrhythmia, hypertension, heart rhythm disorders, or heart disease. However, the contraindications for synephrine use do not stop there. Pregnant or breastfeeding women with glaucoma problems or those who frequently experience migraines or cluster headaches should also avoid taking this compound. Furthermore, taking synephrine in combination with caffeine can enhance the stimulating effect and lead to sleep disturbances. In addition, synephrine shows significant sensitivity to many medications, such as antidepressants or stimulants of the nervous system. Such a mixture can be very dangerous to health or even fatal.
