Which of the following is NOT listed as a key nutrient for hypertension?

Explanation:
The main idea here is recognizing which nutrients are commonly emphasized for supporting healthy blood pressure. Iron doesn’t have a direct, established role in lowering blood pressure or improving vascular function; it’s critical for oxygen transport and preventing anemia, not for BP control. In contrast, magnesium helps promote relaxation of blood vessels and supports endothelial function; folic acid can improve vascular health by lowering homocysteine levels; and vitamin C supports endothelial function through antioxidant effects and nitric oxide availability. That’s why the other three are considered key nutrients for hypertension, while iron is not.
