Flower power: Amaranthus provides eight-hour boost
BEETROOT’S high levels of nitrate have boosted its reputation as a performance-enhancer, the naturally occurring substance said to enhance endurance and recovery.
A powder called Oxystorm, developed by Vitafoods Europe, is produced from Amaranthus leaves and provides 9000mg of nitrate per 100g, more than the amount in standard beetroot powders and juices. Clinical trials published in the journal Nutrition showed a single dose of the leaf extract boosted nitrate levels in the body for at least eight hours.
