Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is the objective of this study to investigate whether a supplementation with Vitamin D3 can be used to reduce atherosclerotic risk factors such as hypertension, inflammation and hyperlipidemia. The research question is whether Vitamin D3 can lower blood pressure in mildly hypertensive subjects who are naive to antihypertensive medication, whether Vitamin D reduces the level of systemic inflammation and whether Vitamin D3 has an effect on blood lipids.

major outcomes:

\- decrease of systolic blood pressure in the treatment group in comparison with the placebo group
