citrus aurantium extract (30% synephrine)
Citrus aurantium extract (synephrine) acts as a stimulant, increasing metabolic rate and providing an energy boost.
What Does Citrus Aurantium Extract Do?
Citrus aurantium, commonly known as Bitter Orange, is a potent botanical extract used to supercharge your metabolic rate and sharpen mental focus. Its primary active compound, p-synephrine, acts as a sympathomimetic agent that targets specific receptors to mobilize fat stores for fuel.
- Metabolic Acceleration: It stimulates beta-3 adrenergic receptors, which triggers lipolysis (the breakdown of fat) and increases your basal metabolic rate without significantly impacting heart rate.
- Sustained Energy: Unlike harsh stimulants that peak and crash, synephrine provides a steady stream of energy that helps you power through the tail end of grueling workouts.
- Appetite Suppression: It helps blunt hunger signals, making it an ideal ingredient for athletes in a cutting phase or those trying to maintain a caloric deficit.
- Synergistic Effects: When paired with caffeine, it enhances the thermogenic response, allowing you to burn more calories during and after your training session.
Clinical vs. Gym Bro Dosing
| Tier | Dose | Notes |
|---|---|---|
| Threshold | 25mg | Subtle metabolic boost; good for beginners. |
| Standard | 50mg | Found in most moderate-intensity pre-workouts. |
| Performance | 100mg | The clinical sweet spot for noticeable energy and heat. |
| Max | 150mg | High-stimulant territory; use with caution. |
Key Insight: Because this specific extract is standardized to 30% synephrine, a 100mg dose provides 30mg of the active alkaloid. This is considered the gold standard for performance, as it provides the metabolic benefits of ephedrine without the dangerous cardiovascular strain.
Side Effects & Warnings
- Elevated Blood Pressure: While generally considered safer than other alkaloids, it can still cause a temporary rise in blood pressure, especially when combined with other stimulants.
- Mild Jitters: Some users may experience slight tremors or a 'wired' feeling if they are sensitive to adrenergic agonists.
- Insomnia: Taking this ingredient too late in the evening can interfere with your sleep cycle due to its long half-life.
Contraindications: Avoid using Citrus Aurantium if you have a pre-existing heart condition or are currently taking MAO inhibitors. Always consult with a medical professional before stacking this with other high-potency stimulants.
