Adequate macro and microvascular endothelial function during pregnancy is essential for the normal placental development and growing fetus. Beetroot juice (BJ) promotes improvement ins this parameters in no-pregnant individuals, however the beneficial effect did not avaliated in pregnant. The present study evaluated effects of BJ on macro and microvascular endothelial function in pregnant. Twelve pregnant were submitted to BJ and nitrate-depleted juice (PLA) interventions. Brachial flow-mediated dilation (FMD) and muscle oxygenation were measured 120 min after interventions. Urinary nitrate, nitrite were measured at baseline and 120 min after interventions.
