Synephrine hydrochloride is a synthetic or semi-synthetic form of synephrine – an alkaloid present in the fruits of Citrus uranium and Citrus aurantium. Thanks to the processing technology, it is possible to obtain a high-purity bioactive ingredient and much easier to measure a precise dose. Hydrochlorides are also known to be very easily absorbed and highly bioavailable. This is emphasised by the fact that they are commonly used to produce e.g. drugs.
After ingestion, synephrine hydrochloride exerts the same effects as synephrine. It stimulates the sympathetic nervous system – it primarily modulates alpha-1A adrenergic receptors. It has a minimal impact on blood pressure, improves blood circulation and promotes well-being. What is more, it seems to stimulate β-andrenergic receptors in adipose tissue. This enhances lipolysis, consequently speeding up body fat loss.
There are single-ingredient formulations with synephrine hydrochloride available on the market. They can be found also in many slimming and pre-workouts at www.muscle-zone.pl
Dosage: No official guidelines.
The available studies suggest that we can take 50 mg of synephrine daily without the risk of side effects.
