Objectives
Narrative objectives1
Social interest in functional foods aimed at preventing and improving lifestyle-related diseases is growing. Particularly, the efficacy of food components (water-soluble silicon) believed to have blood pressure-lowering effects is drawing attention as a non-pharmacological intervention for blood pressure control.
This study aims to verify the effects of continuous 12-week intake of water-soluble silicon on blood pressure in adults with prehypertension or stage I hypertension through a placebo-controlled, randomized, double-blind, crossover trial.
