According to research, low vitamin D levels are associated with higher blood pressure. This study, executed by research departments in Switzerland and the USA, aimed to determine whether higher daily vitamin D supplementation (2000 IU or 50µg) is more effective in controlling blood pressure among older adults than vitamin D supplementation with a standard dose (800 IU or 20µg). During 24 months, 273 patients (aged ≥ 60 years) either received 2000 IU vitamin D or 800 IU vitamin D. Blood pressure was measured at different stages. The results showed that blood pressure variability (fluctuations in blood pressure), a significant risk factor for cardiovascular disease, significantly decreased during the study period. More details can be found in the study.
