When you drink beetroot juice in a cool room, your body produces more nitrite in your blood than when you drink it in a warm room.
Scientific Claim
Acute nitrate ingestion increases plasma nitrite concentration to a greater extent during cool air exposure (20°C) compared to normothermic conditions (28°C) in healthy young males, with plasma nitrite levels reaching 592 ± 239 nM in cool conditions versus 410 ± 195 nM in normothermic conditions.
Original Statement
“Plasma [nitrite] was higher in BR-Cool (592 ± 239 nM) versus BR-Norm (410 ± 195 nM) (P = 0.01; dz = 0.95)”
