SUBJECTS AND METHODS: Ten healthy adult nonsmokers participated in a randomized, double-blind, placebo-controlled, three-arm crossover study. Single doses of C. aurantium (Advantra Z) containing 46.9 mg synephrine, Xenadrine EFX, a multi-component formulation containing 5.5 mg synephrine, and placebo were administered with a one-week washout.
CONCLUSION: Ephedra-free weight loss supplements have significant cardiovascular stimulant actions, similar to ephedra. These effects are not likely caused by C. aurantium alone, because an eightfold higher dose of synephrine (Advantra Z) had no effect on blood pressure, but may be attributable to caffeine and other stimulants in the multi-component formulation.
Los suplementos para perder peso libres de efedra causan una estimulación significa a nivel cardiovascular,similar a la efedra..Esos efectos no son causados unicamente por C.Aurantium,por que dosis ocho veces mayores de sinefrina no tienen efecto en la presion sanguinea,dicho estimulación puede ser atribuida a la cafeina y otros estimulantes presentes en la formulación.
