Synephrine is a chemical stimulant derived from Citrus aurantium, a fruit-producing plant that grows in parts of Asia, Africa, and the Americas. Also known as bitter orange, synephrine exhibits similar stimulatory properties as ephedrine, but with less potency and fewer adverse effects. Synephrine supplements are used to boost energy, increase the metabolism, burn fat, and support weight loss.

Synephrine Use
A stimulatory alkaloid, synephrine influences the alpha adrenergic receptors and produces vasoconstriction, a narrowing of the blood vessels that slows blood flow. With the FDA ban on products containing ephedrine, supplements that include synephrine as an ingredient have grown in popularity due to their ability to increase energy expenditure, boost glucose uptake by muscles, and encourage the breakdown of fat to be used as energy. The effects of synephrine are supported by diet and exercise, and when coupled with caffeine, synephrine’s effects are amplified. Further research is needed to substantiate claims that synephrine is a safe alternative to ephedrine.

Synephrine Side Effects
When used within recommended doses, synephrine is believed to be a safe supplement for use as a stimulant. Still, because of its stimulatory effects, some potentially dangerous side effects can be experienced. Headache, agitation, heart palpitations, and rapid heart rate are common. Due to vasoconstriction, an increase in blood pressure is possible. People with existing cardiovascular-related health issues, such as hypertension, should not supplement with synephrine. While stacking synephrine with caffeine, energy drinks, or other stimulants can amplify the effects, it is important to remember that this will also have a significant and potentially dangerous impact on heart rate and blood pressure, which increases the risk of stroke and heart attack. Synephrine can interact with other supplements and medications. It is recommended that you speak to your healthcare provider before supplementing with synephrine.
