This headline is usually referring to beetroot (beet) juice.
Beet juice is often promoted for heart and blood pressure support because it is naturally high in nitrates, which the body can convert into nitric oxide. Nitric oxide helps blood vessels relax and widen, which may improve blood flow and can lead to a modest reduction in blood pressure for some people.
Other juices sometimes mentioned for artery and heart health include:
- Pomegranate juice — contains polyphenols and antioxidants that may support blood vessel function.
- Tart cherry juice — studied for inflammation and cardiovascular markers.
- Cranberry juice — may have some heart-related benefits, though many commercial versions contain added sugar.
A few cautions:
- Juice is not a replacement for prescribed blood pressure medication or lifestyle changes.
- Many bottled juices contain added sugar, which can work against heart health.
- People with kidney problems or those taking certain blood pressure medications should check with a healthcare professional before making large dietary changes.
If you mean a specific viral post, it’s likely the “one glass” claim is about beet juice.
