Beet juice concentrate is a thick liquid pressed from beetroots and processed to remove water. It packs a much higher dose of dietary nitrates than whole beets or powder. Your body turns those nitrates into nitric oxide, a molecule that relaxes blood vessels and increases blood flow.
Athletes often take it to push through tough workouts. It helps deliver more oxygen to working muscles, so endurance can improve and fatigue may set in later. Two common goals are better stamina in cardio events and faster recovery during repeated sprints.
People also use it for steady blood pressure support. Nitric oxide widens the vessels, which takes pressure off the artery walls. A typical serving is a small 1 to 2 ounce shot mixed into water or juice. For exercise, drink it 60 to 90 minutes before you start. For daily blood pressure support, most people take it in the morning.
This supplement can drop blood pressure noticeably. If you are on blood pressure medication, watch your numbers closely. The concentrate is also high in oxalates, so anyone prone to kidney stones should be careful. Urine and stool can turn reddish after use. That color is harmless but looks a lot like blood.
