Soy supplements may not reduce high blood pressure in older women.

Regular consumption of soy supplements may not help patients with hypertension reduce their high blood pressure, find US researchers. Many studies have showed that soy-rich diets is associated with a lower risk of heart disease compared to western diets, but a new evidence published in the American Journal of Clinical Nutrition says that soy supplements alone may not help hypertension control in older women. The new finding was a result of study which included 24 menopausal women with moderately elevated blood pressure. During the trail, researchers of Baylor College of Medicine in Houston randomly assigned participants to take either placebo pills or 80 milligrams of soy isoflavones per day. After six weeks, they found no significant evidence showing that the supplementation was helpful in high blood pressure control. Some studies have found that intravenous infusions of soy isoflavones may boost the body's production of nitric oxide which lowers blood pressure by dilating vessels. “But we don't take soy by infusion,” note the lead researchers William Wong. “If we didn't see anything in six weeks, we doubt there would be effects (longer term).” “I think that if people are looking for a magic bullet against high blood pressure, this is not it,” he concluded.
