A couple of weeks ago I wrote about CoVid19 and Vitamin D Deficiency. Today I want to focus on vitamin D and heart health.

Additional studies are showing how optimizing your vitamin D intake can help to prevent both heart disease and stroke. And it seems to do this by:

• Improving endothelial function

• Reducing arterial stiffening

Vitamin D does this by increasing your endothelium’s ability to create nitric oxide. Nitric oxide dilates your blood vessels to improved blood flow.

Additionally, vitamin D helps to decrease the destructive chemical compound called peroxynitrite, which can cause inflammation that leads to arterial stiffness.

Researchers at the Nanomedical Research Laboratory at Ohio University conducted a study that examined this relationship between nitric oxide and peroxynitrite. For simplicity, please remember the following:

• Nitric oxide is good

• Peroxynitrite is bad

In their study, the researcher introduced a human hormone called angiotensin-II. This hormone causes endothelial dysfunction. The result was a decrease in nitric oxide and an increase in peroxynitrite.

When vitamin D3 was introduced, this was significantly reversed. There was a 10 fold increase in nitric oxide and a 10 fold decrease in peroxynitrite.

This study suggests that by maintaining normal levels of vitamin D in your blood stream, you can help to maintain normal endothelial function. This helps your body to properly produce nitric oxide for improved blood flow.

And, normal levels of vitamin D help to prevent the destructive peroxynitrite, which can cause vascular inflammation that leads to arterial stiffness.

So the question becomes:
