The Claim
In vitamin D-deficient overweight and obese children aged 10–18 years, daily supplementation with 1000 IU of vitamin D3 for six months reduces central systolic, central diastolic, and systemic diastolic blood pressure by approximately 2.7–3.6 mm Hg compared to daily supplementation with 600 IU of vitamin D3.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In vitamin D-deficient overweight and obese children aged 10 to 18, taking 1000 IU of vitamin D3 daily for six months lowers central systolic, central diastolic, and systemic diastolic blood pressure by 2.7 to 3.6 mm Hg compared to taking 600 IU daily.
See the scientific wording
In vitamin D-deficient overweight and obese children aged 10–18 years, daily supplementation with 1000 IU of vitamin D3 for six months significantly reduces central systolic, central diastolic, and systemic diastolic blood pressure by approximately 2.7–3.6 mm Hg compared to 600 IU/day, suggesting a dose-dependent benefit for cardiovascular risk reduction in this population.
Higher vitamin D levels in the blood turn off a system that normally tightens blood vessels, causing the vessels to relax and blood pressure to drop.
What the research says
1 studyThis study gave kids with low vitamin D and extra weight either 600 or 1000 IU of vitamin D daily for six months. The kids who got 1000 IU had slightly lower blood pressure in their main arteries than those who got 600 IU — just like the claim says.
