A new study has found that taking 600 international units (IU) of vitamin D per day—the amount typically recommended for adults—lowers blood pressure in older adults, especially those who are obese.
Experts caution that exceeding the recommended intake, even below the safe upper limit (UL), does not necessarily translate to additional benefits.
Supplementation Reduced Blood Pressure
The study, published Tuesday in the Journal of the Endocrine Society, involved 221 older obese adults who received vitamin D supplements at either 600 IU per day or 3,750 IU per day over one year. Currently, the Institute of Medicine (IOM) recommends a daily intake of 600 IU.
Partcipants’ overall systolic blood pressure decreased by 3.5 mm Hg after one year, and diastolic blood pressure decreased by 2.5 mm Hg after one year.
Those who took higher doses of 3,750 IU daily had a slightly higher decrease of 4.2 mm Hg for systolic blood pressure. In comparison, those who took the lower 600 IU per day generally reported a reduction of 2.8 mm Hg after one year.
The authors concluded that the differences between the high- and low-dose vitamin D groups were not statistically significant.
People with a higher body mass index (BMI) of over 30 saw more significant reductions in blood pressure, especially in the high-dose group. People who took blood pressure medication with their vitamin D also observed substantial decreases in their overall blood pressure.
All participants also received daily supplements that included 1,000 milligrams of calcium.
