4. Beet juice
Athletes are in love with beets, because they have high levels of nitric oxide, a compound that helps increase their blood flow. Drinking beet juice is a great way to improve your circulation, even if you’re not a sportsperson.
“Some studies have shown that consuming one to two cups of beet juice per day reduced blood pressure in people with high blood pressure and improved walking performance in patients with peripheral artery disease (PAD) who experience pain in the legs during walking,” says Steven Hertzler, PhD, RD, a senior scientist for clinical research in global science and medical affairs at Abbott Nutrition in Abbott Park, Illinois.
