It is also used to treat digestive problems, colds, and headaches. What are the dangers of Bitter orange? Jones describes an open labeled study performed on 9 women. Citrus aurantium supplements for metabolism

Citrus aurantium supplements for metabolism -

would be habitual caffeine consumers. With this in mind, it has been demonstrated that habitual caffeine consumption leads to decreases in the sensitivity to a regular dosage of caffeine [ 8 , 9 , 10 , 11 ], e. Each individual component, Citrus Aurantium and caffeine, primarily work through beta-receptor function and consequently influence downstream metabolic activity such as the regulation of blood glucose, insulin, triglycerides, and catecholamines.

A decrease in caffeine responsiveness in habitual consumers may result in a less robust metabolic response than those reported in earlier studies [ 2 ].

Additionally, we aimed to evaluate post exercise metabolic recovery following an exhaustive exercise protocol. Fourteen apparently healthy males that habitually consumed caffeine were recruited for this study. Physical activity inclusion criteria required all individuals to take part in no less than three-days of aerobic training and two-days of resistance training every week for a minimum of six months.

Participants were recruited by word of mouth from the nearby metropolitan region. Prior to participation, all subjects were provided with procedures and made aware of risks associated with the study and the informed consent was signed.

A health history questionnaire HHQ was administered in order to ensure that participants were able to take part in vigorous physical activity without medical clearance as characterized by the guidelines provided by American College of Sports Medicine [ 12 ].

Individuals reporting of any orthopedic conditions, cardiovascular, pulmonary, or metabolic disease were removed from the study. Participants were requested to wear comfortable clothing, to arrive fasted for a minimum of four-hours, avoid exercise and alcohol for h, and refrain from caffeine usage for h preceding each session to ensure its clearance from the blood [ 11 ].

This study was performed in a double-blind, placebo-controlled, randomized crossover design where only one investigator knew the identification of the supplementation; this investigator did not engage in the gathering or analysis of data.

Participants were requested to attend the Exercise Physiology Lab on two separate occasions, with the second visit taking place within three to nine days after the first visit. The initial visit comprised of obtaining the informed consent, HHQ, and anthropometric measures.

Participant height cm and weight kg were gathered using an electronic physicians scale Tanita WB , Arlington Heights, IL. Upon the completion of the ingestion period, a post-ingestion venipuncture was performed I2. Participants then performed a standardized warm-up prior to initiating the anaerobic exhaustive exercise protocol.

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.
