Anxiety/Nervousness

Synephrine can cause anxiety, nervousness, and jitteriness, especially in sensitive individuals or at higher doses, due to its stimulant effects on the sympathetic nervous system.

Synephrine, acting as a stimulant, can induce feelings of anxiety, nervousness, and jitteriness. These symptoms are often more pronounced in individuals who are particularly sensitive to stimulants or who are taking higher doses. The anxiety can manifest as excessive worry, restlessness, and difficulty concentrating. Nervousness may present as an uneasy or apprehensive feeling, while jitteriness involves shakiness or tremors. These effects are likely due to synephrine's interaction with the sympathetic nervous system, leading to increased levels of norepinephrine and epinephrine, which can trigger the fight-or-flight response.
