Synephrine has a better safety profile than ephedra/ephedrine. It preferentially activates beta-3 receptors in fat tissue rather than cardiovascular alpha/beta-1 receptors. At standard doses (25-50 mg/day), clinical reviews show no significant increases in blood pressure or heart rate. However, avoid combining with multiple other stimulants.

The combination is common in supplements and may be synergistic for thermogenesis. Most safety reviews suggest the combination is tolerable at standard doses (25-50 mg synephrine + 100-200 mg caffeine). However, sensitive individuals should start with lower doses and monitor for cardiovascular effects.
