Oral nitrate and citrulline decrease blood pressure and increase vascular conductance in young adults: a potential therapy for heart failure.

For subjects at rest, both nitrate and citrulline decreased pulse interval measured at the thumb 15 %, for nitrate treatment this did not reach statistical significance (NS; Fig. 3 a), whereas for citrulline this was significantly different from untreated subjects ( p < 0.05; Fig. 3 a).
