Latest Research
Recent research on circulation and vascular health, summarized in plain English. Each summary covers the question, who was studied, what was found, and what the study can’t tell us.
What the researchers set out to learn, in one plain sentence.
People, animals, or cells — and how many, for how long.
What was measured and what changed, without the spin.
Study design, size, funding, and what it can’t prove.

Movement
How walking, exercise, and long periods of sitting relate to measures such as blood vessel flexibility and blood flow in the legs — and why short-term lab measures don’t always predict long-term outcomes.

Why beets and leafy greens keep showing up in circulation research, what “nitric oxide” has to do with it, and the difference between a short trial and a lasting effect.
Read the guideSleep & stress
What studies on sleep patterns and stress responses can — and can’t — tell us about blood pressure and the lining of blood vessels.
