Humans do not make Vitamin C like animals do, we need to supplement this essential vitamin to meet our daily needs. Vitamin C and Lysine work together to build collagen, which strengthens and holds together the coronary cells. Inadequate amounts of Vitamin C means poor collagen. Coronary cells then fall apart just as bricks do without good mortar. Coronary arteries, closest to the heart, receive the greatest pressure. Without enough Vitamin C the collagen weakens. This sets the stage for heart attack. The work of Dr. Sydney Bush shows that vitamin C + lysine can help reverse the process.
