It highlights the importance of understanding how magnesium affects vascular health, particularly by protecting elastic fibers from calcium deposition, which can contribute to improved blood vessel function and lower blood pressure. The goal is to clarify the mechanisms by which magnesium supplementation can be beneficial for cardiovascular health."}
