NCT01960946

Brief Summary

This study will investigate if Modified Citrus Pectin (MCP) can help people with high blood pressure. MCP is a dietary supplement that is derived from plants, and therefore is not subject to approval by the U.S. Food and Drug Administration (FDA). However, MCP has been deemed as 'generally regarded as safe' by the FDA. This study will examine whether Modified Citrus Pectin (MCP) can help people with high blood pressure. The study will help understand how MCP may affect the risk for heart disease in patients with high blood pressure.
