Synephrine is a chemical alkaloid manufactured from the fruit of the Citrus aurantium plant found in Africa, Asia, and parts of the Americas. Commonly referred to as bitter orange, synephrine is a stimulatory agent that has similar effects as ephedrine. Ephedrine is a substance banned by the FDA, but synephrine is less powerful and is thought to have fewer side effects associated with its use. As a stimulant, synephrine is used to increase the metabolism, boost energy, support fat burning, and help encourage weight loss.

Synephrine Use
Synephrine is a stimulatory alkaloid that takes effect on the alpha adrenergic receptors, causing vasoconstriction, which is a narrowing of blood vessels that restricts and slows blood flow. Due to the FDA ban on ephedrine, manufacturers are turning to synephrine to produce similar effects, although less pronounced, as those provided by ephedrine. Synephrine supplements deliver a boost in energy and an increase in glucose uptake by the muscles while also supporting the breakdown of fat tissue for use as energy during exercise. Diet and exercise further the effects of synephrine, and the effects of caffeine and synephrine are amplified when taken together. Although synephrine’s effects are less potent than ephedrine, more research is needed to determine whether these supplements have fewer associated adverse effects.

Synephrine Side Effects
Synephrine is thought to be a safe stimulant when used within the recommended doses. Regardless, synephrine is a central nervous system stimulant, and some side effects are to be expected. Agitation, headache, rapid heart rate, and heart palpitations may be experienced. There is evidence showing that synephrine supplements cause an increase in blood pressure, and when coupled with an increased heart rate, the added stress on the cardiovascular system can result in negative consequences. Individuals with existing cardiovascular-related difficulties, like hypertension, should not supplement with synephrine. Although more research is necessary, synephrine may produce similar risks as those associated with ephedrine, such as an increase in the risk of stroke and heart attack. Synephrine can interact with other medications and dietary supplements. You should speak to your doctor or health practitioner before supplementing with synephrine.
