Super Food: Oranges fight cancer and are heart healthyBitter orange and cardiovascular health -
Population studies suggest that limonene may prevent certain cancers, namely colon cancer. However, more rigorous human research is needed An ongoing study is also exploring the use of limonene as a treatment for COVID However, the results are not yet known.
Bear in mind that limonene cannot prevent or cure COVID Another protoalkaloid found in bitter orange is p-octopamine. However, little to no p-octopamine exists in bitter orange extracts.
The leaves of the bitter orange plant are rich in vitamin C , which acts as an antioxidant. 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. Likewise, bitter orange supplements are banned for NCAA athletes.

Turmeric has shown some promise in reducing inflammation, including in patients with osteoarthritis. There may be some evidence that it can even slow the growth of cancer cells and be good for heart health. Not only can it lead to liver damage , but high doses of turmeric can also cause blood-thinning.
And if taken with blood thinners, turmeric could cause increased risk of dangerous bleeding, according to the British Heart Foundation.
Belardo said that since herbal supplements aren't strictly regulated by the FDA, there isn't consistency in how they're made, which makes getting high doses a concern. Some supplements may also be contaminated with undisclosed ingredients.
Derived from the same tea leaves used in your favorite matcha latte, green tea extract is thought to increase mental alertness and help with weight loss, according to the NIH. Some research suggests that drinking green tea or taking green tea extract may be beneficial for heart health as well, according to Cleveland Clinic.
Caffeine found in green tea extract can sometimes create problems, for example by raising blood pressure, which can be problematic for those who already have high blood pressure.
Excessive caffeine, including through green tea extract, could also lead to heart palpitations, according to Mount Sinai.
Popular for its potential to treat mild to moderate depression , St. John's Wort is a yellow-flowered plant that has a long history in traditional European medicine.
But St. John's Wort can interact with numerous medications in potentially dangerous ways, Belardo said. Two common heart medications that St.
John's Wort can have interactions with include digoxin, prescribed to help treat certain arrhythmias and to manage heart failure, and ivabradine, prescribed to help with chronic heart failure , according to the NIH. John's Wort can make both of these medications less effective.
Bitter orange, also known as Citrus aurantium , comes from a tree native to Asia. Bitter orange has become a popular ingredient in bodybuilding and weight-loss products, although it is not yet known whether bitter orange actually helps with either of these goals, according to the NIH.
But bitter orange can harm healthy people, Belardo said. Specifically, bitter orange has been linked to irregular heartbeats, known as arrhythmia. Read next. Close icon Two crossed lines that form an 'X'. It indicates a way to close an interaction, or dismiss a notification.
HOMEPAGE Newsletters. Kate Hull. Share icon An curved arrow pointing right. Figure 3. In the placebo protocol, pNN50 index values continued to be significantly decreased throughout 20 min of recovery related to resting values Rest: Our findings demonstrate that the ingestion of C. aurantium p-synephrine mg prior to exercise fast-tracks the fall in SBP after physical exertion.
Earlier studies propose that one of the benefits of using C. aurantium equated to other adrenergic substances e. Activation of β-3 adrenergic receptors triggers reverse inotropic effects, antagonizing the activation of further classes of adrenoreceptors β-1 and β-2 in cardiac tissue and, thus, decreasing sympathetic modulation to the heart.
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.
