Nitrate Supplements - A Natural High
Nitric oxide is an important chemical secreted by the blood vessels that increases tissue blood flow. The erection-promoting drug Viagra increases nitric oxide levels and blood flow to the penis and improves exercise capacity at altitude. British researchers from the University of Exeter found that beetroot juice, which is high in nitrites and promotes nitric oxide synthesis, improved exercise tolerance in healthy adults exercising at simulated altitude. Nitrate supplements appear valuable for increasing endurance performance and could help people cope with altitude exposure. (Journal of Physiology, published online)
