What Happens to Your Blood Pressure When You Take Vitamin D Supplements - Verywell Health

Research suggests that vitamin D supplementation might assist in lowering blood pressure for individuals deficient in this nutrient, especially among those already suffering from elevated blood pressure levels. While some studies indicate a correlation between low vitamin D levels and high blood pressure, results from supplementation trials are varied, with some showing beneficial effects while others do not demonstrate significant changes. It appears that older adults who are both deficient in vitamin D and experience high blood pressure could have the most notable improvements from taking these supplements, although the extent of benefit is not guaranteed. General dosing recommendations range widely, with the daily intake suggested being between 600 to 4,000 IU depending on age and health context. While many can safely consume vitamin D daily, excessive intake can lead to toxicity, underscoring the importance of adhering to recommended levels and consulting with healthcare providers for personalized advice.
