BackgroundThere are still no studies of the cardiovascular safety of the isolated use of Citrus aurantium in aerobic submaximal exercise.Citrus aurantium for physical endurance -
Immediately following the exercise protocol a post-exercise venipuncture was performed R1 and then the min recovery period was initiated. At the end of this recovery period the final venipuncture was taken R2. The study design can be seen in Fig.
Participants were immediately walked to an electronically braked cycle ergometer Sport Excalibur, Lode BV, Groningen, The Netherlands , where the bike was adjusted to the appropriate settings in order to ensure the knee was at a slight bend at the bottom of the revolution.
Bike settings were repeated for both trials. Following the appropriate adjustments, participants feet were strapped into the pedals and the protocol was initiated. Each Wingate test was s in duration and participants were encouraged to pedal at their maximal effort against a resistance of 0.
There was a total of three Wingate tests performed with a two-minute active recovery period between each test. At the completion of the last Wingate test, participants were walked to a separate room to undergo a post exercise venipuncture and to begin the recovery measures R1-R2.
Pre-testing protocols on the electronically braked cycle ergometer followed manufacturer guidelines. Blood draws were collected via the antecubital vein by a trained phlebotomist during four-time points throughout the study: I1, I2, R1, R2 Fig.
In order to account for the plasma volume shifts following the exercise bout, all E and NE samples were normalized by using the established protocols of Dill and Costill [ 14 ].
Hematocrit Hct and hemoglobin Hb were collected via finger sticks at each venipuncture time point Alere Hemopoint 2. Blood glucose GLU was measured using a Medtronic Contour glucometer Bayer, Pittsburgh, PA via finger stick.
The procedures and findings of plasma catecholamines were previously reported and permissions granted by the publishing Journal [ 15 ].
Citrus Aurantium and caffeine powder were purchased from Blackburn distributions Caffeine powder, Blackburn distributions limited, Nelson Lancashire, England; Citrus Aurantium powder, Blackburn distributions limited, Nelson Lancashire, England. Each component was measured using an electronic supplement scale and encapsulated in green, non-translucent, size zero gelatin capsules.
All data were analyzed using the statistical software package SPSS SPSS, Version 24 for Mac, Chicago, IL. In order to determine the effect size, the recommend guidelines of Quintana were used.
Of the fourteen participants who volunteered for the study, four were removed due to adverse reactions to the phlebotomy procedure i. Therefore, a total of ten physically active males completed the study. Participant characteristics can be seen in Table 1. Plasma Insulin.
Blood Glucose. Means ± SD can be seen in Fig. Plasma Triglycerides. Means ± SD can be seen in Figs. Plasma Epinephrine. Plasma Norepinephrine. No significant trial differences occurred in insulin, lactate or triglycerides throughout the ingestion period.
Under normal fasted conditions it is not uncommon to observe a slight decrease in blood glucose with concurrent decreases in insulin concentration over a prolong period of rest [ 17 , 18 ]. Blood glucose concentration following the PLA trial is reflective of this response, with a significant drop occurring at I2.
No changes in glucose concentration occurred and was found to be significantly higher than that of the PLA trial at the I2 time point. The medium by which the supplements were delivered in the current study were capsules absent of carbohydrate and would rationalize the difference in observations between the two studies.
Similar to glucose, insulin has been shown to be maintained or decrease during resting and fasted conditions [ 19 ]. This is in contrast to Graham et al. However, the differences in observations can likely be attributed to the dosage of caffeine Graham et al. The caffeine components role in sympathetic nervous system SNS mediated glucose release [ 22 ] may be another likely contributor to the observed glucose response.
Additionally, Stuart et al. The CA component of the complex is another mechanism by which the maintenance of blood glucose could have occurred. Specifically, the active ingredient p-synephrine acts on beta-3 receptors in order to increase lipolysis [ 1 ], thereby acting to spare blood glucose.
Future research should examine varying concentrations in order to determine a dose effect. The exhaustive exercise trial selected for this study was a repeated Wingate protocol designed to induce a high metabolic stress and fatigue. Following the completion of the trials, no differences in glucose, insulin, triglycerides, or catecholamines were observed.
However, insulin did not statistically elevate immediately post-exercise but demonstrated a non-statistical increase at the end of the recovery period. Previous research has demonstrated insulin spikes immediately following prolonged high-intensity protocols [ 25 ]; however, the duration of those protocols was ultimately longer than the one used previous studies and may have led to the different insulin response.
Though fat oxidation was not directly measured throughout this study, plasma triglycerides were obtained to determine changes in metabolic function. A primary function of the Citrus Aurantium is improved lipid peroxidation through p-synephrine and beta-3 activation, which may alter the release of triglycerides following exercise based on demand, and ultimately influence metabolic recovery.
Post-exercise plasma triglycerides have been shown to account for half of the delayed component of excess post exercise oxygen consumption EPOC [ 26 , 27 ], which is a beneficial response to high-intensity exercise. Interestingly, both trials showed spikes in plasma triglycerides at R1 when compared to I2, though no difference was observed between trials.
Furthermore, various dosages of this complex should be evaluated in order to better determine a dose-response effect. The markers used to examine metabolism were glucose, insulin, and triglycerides; future research should examine a more extensive metabolic profile including substrate utilization and free fatty acids.
Though a priori analysis based on a power of 0. However, this was not enough to elicit changes in resting insulin, or triglycerides. These findings suggest practical implications of hypoglycemic prevention during prolong i.
Further research is needed to examine a dose and component response on these metabolic markers. Stohs SJ, Preuss HG, Shara M.

A staple of Chinese medicine for centuries, the ingredient frequently appears in health supplements including those geared towards athletic performance. The benefits related to physical performance are said to derive mostly from p-synephrine, a mild stimulant in citrus aurantium.
Meanwhile, consumption of caffeine alongside p-synephrine, increased the velocity of squat performance which probably explains why citrus aurantium is often combined with caffeine in sports nutrition supplements. A comprehensive review of published studies involving citrus aurantium and p-synephrine supports its usage for weight loss.
An entirely separate study , meanwhile, found that subjects who supplemented with bitter orange were better able to control their calories — probably because their appetite was mildly suppressed. And a third showed that for people exercising at low-to-moderate intensity, p-synephrine increased the rate of fat oxidation while reducing the rate of carbohydrate oxidation.
