Antioxidants are substances that may protect your body from disease by preventing cell damage. They work by deactivating free radicals, which are unstable compounds that damage your cells, increasing inflammation and your disease risk 15 , Protoalkaloids are plant compounds found in bitter orange that have anti-inflammatory and antiviral properties.
They have been shown to be safe for consumption. Many weight loss supplements use bitter orange extracts in combination with other ingredients. However, scientific studies have not thoroughly examined the composition of these supplements to determine which ingredient, if any, supports weight loss.
Notably, p-synephrine has been shown to increase fat breakdown, raise energy expenditure, and mildly suppress appetite , all of which may contribute to reduced weight. Yet, these effects occur at high doses that are discouraged due to the lack of safety information 4 , 8 , Bitter orange and its extracts are used in Traditional Chinese Medicine TCM to treat indigestion, diarrhea, dysentery, and constipation.
In other regions, the fruit is used to treat anxiety and epilepsy 3. Another study noted that the bitter orange compound p-synephrine may improve athletic performance though by increasing total reps and volume load, or your ability to train harder A stimulant is a substance that increases your heart rate and blood pressure 1.
Several sports organizations, such as the National Collegiate Athletic Association NCAA , list synephrine as a stimulant. Furthermore, one study determined that bitter orange juice contains furanocoumarin, a compound that may cause the same medication interactions as grapefruit juice Therefore, people taking decongestants or those who have high blood pressure, an irregular heartbeat, or glaucoma should avoid the juice and fruit of bitter oranges.
Despite numerous studies showing that bitter orange extracts are not stimulants, widespread controversy exists, and the NCAA has listed it as a banned substance.
Bitter orange may also interact with certain medications. Generally, bitter orange extracts in dietary supplements are safe to consume in doses of 50—98 mg per day 1 , One study showed that 40 mg of synephrine combined with mg of caffeine is a safe dose of these combined ingredients 3.
In another study, eating a whole bitter orange containing Still, people who are pregnant or breastfeeding should avoid bitter orange due to a lack of safety information 1. Bitter orange is likely safe in doses ranging from The juice of the bitter orange can be used as a marinade to flavor fish and meat.
Bitter orange has several other household uses outside of the kitchen. These include 2 :. Bitter orange is a citrus fruit with several household and industrial uses, ranging from food additives to perfumery. You may want to avoid this fruit and its extracts if you have high blood pressure, an irregular heartbeat, or glaucoma.

Nutrition Evidence Based What Is Bitter Orange, and Does It Aid Weight Loss? Citrus Aurantium: Also known as bitter orange , Seville orange , zhi chi , and chongcao , citrus aurantium is a member of citrus trees and its fruits and leaves have been used for medicinal and athletic purposes.
The peels of bitter orange contain synephrine, octopamine, tyramine, hordenine, N-methyltyramine, volatile oils , and carotenoids. Athletic Benefits of Citrus Aurantium: Since ephedrine has been banned in sports, synephrine — containing citrus aurantium may be a good alternative.
The potential athletic benefits are as follows: May improve athletic performance by acting as a mild stimulant. Promotes mental clarity. Helps promote athletic agility. Useful in weight loss by decreasing appetite and increasing basal metabolic rate BMR.
Non — Athletic Benefits of Citrus Aurantium: Citrus aurantium may be beneficial in the following conditions: Gastrointestinal discomforts, such indigestion, constipation, and abdominal pain.
Weight management. Loss of appetite. Citrus Aurantium Triple Paradox: Depending on whether you take extracts of the leaves or peels of the immature or mature fruits, citrus aurantium shows three paradox effects: It may increase appetite, while it could suppress appetite due to a high amount of pectin.
It acts as a mild stimulant, while it has been used as a sedative in insomnia as well. While some has used it for high blood pressure, it actually increases blood pressure. Contraindications: Citrus aurantium should be avoided in the following conditions: People with high blood pressure.
People with depression who take the medications MAO inhibitors. Citrus aurantium contains tyramine that interacts with MAO inhibitors, leading to hypertensive crisis a sudden increase in blood pressure. Heart diseases. Along with statins, the cholesterol — lowering medications.
Pregnancy and breastfeeding. Peripheral artery disease.
Synephrine has dosags effects Citrus aurantium dosage to that of ephedrine. It is a Citrus aurantium dosage stimulant that Orange Juice Recipes gotten Citrys lot of attention in the world of sports nutrition. Synephrine mainly stimulates Beta-3 receptors that are responsible for lipolysis and thermogenesis. Athletic Benefits of Citrus Aurantium:. Since ephedrine has been banned in sports, synephrine — containing citrus aurantium may be a good alternative.Citrus aurantium dosage -
This clarifies why overall, the binding of p-synephrine with β-3 adrenergic receptors does not increase BP or HR, displaying cardioprotective effects In this study, in the placebo intervention, for the spectral analysis, the HF index, representative of parasympathetic modulation, needed 10 min after termination of exercise to recover.
aurantium protocol, we did not find substantial changes in the HF index in exercise recovery vs. Analogous deviations occurred in the pNN50 index and were reduced 20 min after cessation of exercise in the placebo protocol.
While in the protocol with C. aurantium , this index continued to be reduced for only 10 min after exercise. aurantium protocol, transformations were only following 5 min of recovery. However, in the C. aurantium protocol, the values were only meaningfully reduced for 5 min after the cessation of exercise.
These observations make C. aurantium a safe nutritional compound to be applied during exercise, which supports the recovery of autonomic parameters following exercise. Since a slow post-exercise autonomic recovery is linked with an increased cardiovascular risk 25 , the results of our study indicate that C.
aurantium compounds have a potential preventive role on the onset of cardiovascular complications in physical exercise. As caffeine and C. aurantium are frequently sold as complementary formulas for use in humans, preceding studies have assessed the effects of using these substances alone and in combination.
Through a randomized clinical trial, Guitiérrez-Hellín et al. aurantium alone or in combination with caffeine would have different results for fat utilization during aerobic physical exercise.
No superiority was found between C. aurantium alone and combined with caffeine on the total values of fat consumption during the physical exercise session, while both interventions were superior to the placebo treatment. This supports the isolated use of C. aurantium an alternate way to be applied as an adjunct in cutting body fat without inducing cardiac risk.
In the study by Guitiérrez-Hellín et al. aurantium isolated supplement. In contrast, the HR and SBP were significantly higher when caffeine was included in the formulation.
Our study achieved no changes for HR, and SBP was lessened more quickly following exercise. The identification of β-3 adrenoreceptors in cardiovascular tissues posed challenges to the paradigm of sympathetic regulation by β-1 and β-2 adrenoceptors. The binding response of p-synephrine to the β-3 receptor may elucidate why no increase in HR or BP is detected when C.
aurantium is enforced alone. In contrast, when C. aurantium is combined with caffeine in dietary supplements, it is capable of affecting these parameters, particularly in caffeine-sensitive individuals It has been revealed that the combination of these substances promotes a significant increase in the concentration of plasma catecholamines e.
The study by Kliszczewicz et al. aurantium upsurges sympathetic modulation to the heart throughout rest and corroborates the increases in HR and SBP achieved in the study by Guitiérrez-Hellín et al.
It is assumed that caffeine alone can increase HR during physical exercise Despite that, a recent meta-analysis demonstrated that caffeine could not delay vagal return to the heart after exercise, evaluated by the HF and root mean square of successive differences between RR intervals RMSSD indices Equally, Kliszczewicz et al.
aurantium combined. Caffeine and C. aurantium combination have no extra effects on exercise fat utilization 5. These substances appear to exhibit the opposite cardiovascular effects and, thus, caffeine seems to overlap the beneficial effects of the isolated use of C.
aurantium on cardiovascular health. In this study, C. aurantium supplementation alone optimized the recovery of SBP and HRV indices after exercise. The nutritional characteristics demonstrated in the flavonoids e. aurantium perform antioxidant and anti-inflammatory activities, which are partly answerable for accelerating the return of parasympathetic control of heart rate seen by vagal indices of HRV.
Such properties can hasten the removal of metabolites produced by physical exercise, restoring baroreflex sensitivity and decreasing metaboreflex activation more quickly at the end of physical exercise While C.
aurantium exhibited cardioprotective effects, it is essential to be careful with its usage. Bui et al. Yet, in other studies that enforced doses beneath mg in an acute 5 , 30 , 31 and chronic for 15 days 32 form, no changes were achieved for the HR, SBP, and DBP values, nor electrocardiographic disturbances.
Likewise, our results do not support the findings of Bui et al. The results from the study of Ratamess et al. In your results, the p-synephrine supplementation mg did not evoke changes in HR before, during, and following resistance exercise unless mg of caffeine was added to the formulation.
The same occur in the rest situation, in another study by Ratamess et al. The study of Bui et al. Although it is a randomized and crossover study, there is a lack of information about allocation order in the study.
aurantium, and provoked adjustments in blood pressure, because of higher sweet and fat content e. Furthermore, the authors did not report guarantees that snack was equal on the others evaluation days.
Bitter orange caused cardiovascular effect was only observed based on statistical adjustments. A difference was seen compared to placebo but not when compared to baseline. All these factors raise questions about the validity of their conclusions.
The results recognized in our analyses will advance health professionals' conduct who work with the prescription of nutritional supplements. Consequently, it may be an alternative way to replace other compounds that demonstrate similar contributions regarding fat utilization during exercise but that promote unwanted cardiovascular effects e.
Our study highlights important points about the study population, given that it is restricted to healthy and physically active males. Notwithstanding the number of participants having exceeded the sample size calculation, the final sample is considered small.
With the desire to improve body composition. In spite of this, these facts do not allow these results to be extrapolated to other populations and, therefore, further research with obese individuals is needed to confirm the safety of using C.
aurantium in combination with exercise. For the time being, we prefer to use a healthy population free from metabolic disorders to prevent possible adverse events from C. aurantium supplementation.
Nevertheless, we encourage further studies to be established with C. aurantium as an intervention with these preliminary data. Studies with females and other health conditions should also be performed to increase the external validity of these data and expand the application of C.
aurantium promoted the resumption of parasympathetic control and output of sympathetic flow of cardiac rhythm after physical exercise and decreased SBP. Based on these and previous findings, we assume that C.
aurantium is a safe nutritional compound with submaximal aerobic exercise in healthy males when used appropriately, moreover, your combination with a good diet there could be improved fat oxidation in exercise without the cardiovascular risk.

This enhanced release by l-synephrine was blocked by nisoxetine. Brown and co-workers examined the effects of the individual enantiomers of synephrine on α 1 receptors in rat aorta , and on α 2 receptors in rabbit saphenous vein.
In the rabbit saphenous assay, the pD 2 of l-synephrine was 4. Synephrine constrictions were also antagonized by BRL, , [p] but not by SB, used here as a selective 5-HT 1B antagonist , or by propranolol a common β antagonist.
In studies on guinea pig atria and trachea , Jordan and co-workers also found that synephrine had negligible activity on β 1 and β 2 receptors, being about x less potent than norepinephrine.
Experiments with cultured white fat cells from several animal species, including human, by Carpéné and co-workers showed that racemic synephrine produced lipolytic effects, but only at high concentrations 0.
The potency, expressed in terms of pD 2 of synephrine in these species was as follows: rat: 4. Synephrine behaved as a partial agonist at α 1A receptors, but as an antagonist at α 2A and α 2C sub-types.
A number of studies of the effects of synephrine in humans, most of them focusing on its cardiovascular properties, have been performed since its introduction as a synthetic drug around The blood pressure increase reached a maximum ~25 mmHg in 5 minutes following the injection, then gradually returned to normal over the course of 1 hour.
Doses of drug greater than mg caused side-effects such as heart palpitations, headache, sweating, and feelings of apprehension. When given intravenously , doses of 25—50 mg sufficed to produce a mean maximum increase in the blood pressure of 29 mmHg in 2 minutes, and a return to baseline within 30 minutes.
Respiration was generally not affected during these experiments. The i. administration of 75— mg of synephrine did not relieve acute asthma attacks, contradicting an earlier claim. There are a number of studies, references to many of which may be found in the review by Stohs and co-workers [86] dealing with the effects produced by dietary supplements and herbal medications that contain synephrine as only one of many different chemical ingredients.
The acute toxicities of racemic synephrine in different animals, reported in terms of "maximum tolerated dose" after s. Generally, this treatment did not result in significant alterations in biochemical or hematological parameters, nor in relative organ weights, but some changes were noted in glutathione GSH concentration, and in the activity of glutathione peroxidase GPx.
In insects, synephrine has been found to be a very potent agonist at many invertebrate octopamine receptor preparations, and is even more potent than octopamine at a locust Schistocerca americana gregaria nerve-muscle preparation. Stimulants: Phenylethanolamine.

aurantium , whereas a close reading of the text of the paper itself reveals that the authors although apparently uncertain about which synephrine regio-isomer had been found in the plant by earlier investigators were aware that their analytical technique could not distinguish between m - and p -synephrine, and did not claim that m -synephrine was present.
Thus the Abstract is at variance with the experimental findings given in the full text of the paper, but this error has propagated through subsequent publications.
