This sweet juice is so great for all things circulation. Beets are naturally high in antioxidants and nitrates (which improve blood flow by naturally increasing nitric oxide). In a very basic description, it opens up your blood vessels and gets your blood flowing. So it can improve all things blood-flow related including lowering blood pressure. And don’t forget to wash and juice the beet greens as well. There are a ton of phytonutrients in those.
Some people find the peel to be too “earthy” tasting. I don’t mind it, so I just scrub it. But if you are going to peel it, be sure to wear gloves and use a not-special cutting board. Beet juice will stain the heck out of your hands and you’ll be running around like Lady MacBeth for a few days.
