Research from the University of Exeter has revealed taking a dietary supplement to boost nitric oxide in the body can significantly boost stamina during high-intensity exercise.



The study has important implications for athletes, as results suggest that taking the supplement can allow people to exercise up to 20% longer and could produce a 1-2% improvement in race times.



This comes on the back of previous research from Exeter which showed that the high nitrate content of beetroot juice, which also boosts nitric oxide in the body, has a similar effect on performance.
