Decreased soreness as a result of anti-inflammatory ingredients.
The effects of the consumption of anthocyanins were tested in a double-blind, randomized trial of runners participating in a 24-hour relay race. Runners drank two 355-milliliter beverages containing either tart cherry juice or a placebo beverage daily for one week after the race. Both groups reported pain after the race. But the runners who drank tart cherry juice experienced a substantially smaller pain increase after the race. This natural protection against acute muscle soreness suggested that anthocyanins (active component in tart cherries) must be providing some defense against muscle damage.
