Cranberry Extract For Elite Rowers

Training hard and often can stress your body. It can also contribute to oxidative stress, which has the potential to damage cells. Would supplementing with an anti-oxidant like cranberry extract help? A study published in the Journal of the International Society of Sports Nutrition had national level rowers supplement with 1,200 mg of cranberry extract daily for 6 weeks.
 
Before and after the supplementation period, 16 subjects performed a 2,000 meter test on a rowing ergometer. Blood samples were taken one minute after each exercise test and 24 hours into recovery. Compared to subjects who received a placebo, cranberry extra supplementation strengthened antioxidant potential. But it didn’t have any effect on inflammation or iron metabolism.
