Overview
Redusyn is a weight loss product and currently when trying to search for this supplement online, very little information is available to assess it. What was found though is that the active ingredient in the weight loss pill is a compound known as synephrine.
Now, noradrenaline (and adrenaline) are hormones that are released by the adrenal glands in response to a "fight or flight" situation in humans. The hormones cause the blood vessels in the body to constrict to direct blood flow to the muscles and vital organs so that one can react faster in a life-or-death scenario. These hormones also elevate one's blood pressure and heart rate.
Synephrine in Weight-Loss Products
The synephrine used in products such as Redusyn is usually present as a natural component of bitter orange (Citrus aurantium) and is bound up in the plant matrix of the fruit. What is important to take note of though is that synephrine could also be synthesized in a laboratory or extracted from the plant source and purified and then added to these weight-loss products.
Effects of Synephrine in Humans
In one study, synephrine was injected intramuscularly in human participants at a dose of 200mg, which is a normal dose when managing conditions where a drug/hormone such as noradrenaline would be needed, such as a severe allergic reaction. The effects on the participants were that their heart rates increased and their systolic (upper) blood pressures elevated.
When a dose of greater than 200mg was given, the participants experienced issues such as heart palpitations, severe sweating, headaches, and feelings of apprehension.
Conclusion
As mentioned, Redusyn contains synephrine as the active ingredient which helps the user shed some unwanted weight. How this compound achieves this is by causing the body's metabolism to increase which means that more energy is used up by the individual thus resulting in weight loss.
The mentioned adverse events of synephrine seem to occur when the drug itself is injected into the individual and the oral intake of the drug seems to not cause many issues.
As always, if one wants to embark on using a supplement to assist with weight loss, this should be discussed with one's primary care doctor.
