See the technical phrasing

In vitamin D-deficient overweight and obese children aged 10–18 years, supplementation with 1000 or 2000 IU/day of vitamin D3 for six months has no significant effect on arterial endothelial function, arterial stiffness, lipid profile, or systemic inflammation markers compared to supplementation with 600 IU/day.

Why this might work
Supported
based on 1 study

When vitamin D levels rise, it activates receptors in the kidneys and blood vessels, which reduces a hormone that tightens blood vessels, leading to lower blood pressure. It also improves how muscle and fat cells take up sugar, lowering blood sugar. These changes happen without affecting how well blood vessels relax, how stiff arteries become, cholesterol levels, or inflammation in the body.
