With nearly 40 scientific studies published on the wide-ranging benefits of tart cherries, scientists are now discovering important new health applications for this American fruit. Tart cherries are packed with unique beneficial compounds that have been shown to block COX-1 and COX-2 enzymes,1 as well as maintain muscle function and promote rapid muscle recovery after exercise,2-5 bringing faster relief from the minor aches, discomfort, and stiffness that can follow everyday muscle exertion.2,3
In human studies, researchers have scientifically confirmed the muscle supporting benefits of tart cherries. For example, a randomized controlled trial found that consuming tart cherry juice twice daily produced a substantial decrease in muscle symptoms related to exercise. In the same study, the exercise-induced loss of strength over the four days following a workout was reduced from 22% to only 4%.4
In another randomized controlled trial, marathon runners given tart cherry juice for five days before a race, on race day, and for two days after a race experienced significantly faster recovery of isometric strength and muscle function.3 And in yet another controlled trial, tart cherry juice taken twice daily for seven days prior to a race produced a significantly smaller increase in post-race pain, according to a standard pain assessment scale, compared to the placebo group.2
Anthocyanins are powerful molecules that provide the dark pigmentation to blueberries, raspberries, and bilberries.6,7 In addition to being potent antioxidants, anthocyanins have been extensively studied for their numerous health benefits that include heart, cellular, and cognitive health.6-8
What has drawn the attention of scientists is the fact that tart cherries not only contain a higher content of anthocyanins than other fruits, they also contain unique anthocyanins not found in other berries.1 To allow members to take full advantage of these discoveries, Life Extension® now offers Tart Cherry Extract, a 100% natural supplement that opens the door to the remarkable benefits of continued physical activity—at any age.
This formulation provides all the muscle-supporting benefits of tart cherries and mimics the anthocyanin dose used in successful clinical trials by providing a standardized 40 mg anthocyanins per capsule.2,4
