Higher serum 25(OH)D levels (>=30 ng/ml) are associated with a lower incidence of hypertension and lower blood pressure.
Maintaining Vitamin D levels above 30 ng/ml may help lower blood pressure and reduce the risk of hypertension, potentially through regulating the renin-angiotensin system.
ModerateSupportsMEDIUM confidence
two large prospective cohort studies among men and women reported that the serum level of 25(OH)D associated with the lowest incidence of hypertension is 30 ng/ml or higher, with a significant inverse trend between baseline 25(OH)D and incidence of hypertension over a 4-yr follow-up.
Why this rating
Based on observational studies and a few RCTs; causal link from supplementation is not fully confirmed.
