Anthocyanins are potent antioxidant compounds with a wide range of health-promoting properties, especially for your muscles, providing faster relief from the minor discomfort and stiffness that can follow exercise.^1-6 And tart cherries have a very high anthocyanin content.

Anthocyanins support exercise performance by promoting healthy blood flow and vascular function, supporting metabolic pathways, and inhibiting peripheral muscle fatigue. ^7-8. In a randomized controlled trial, consuming tart cherry juice twice daily over seven days provided substantial relief in muscle discomfort after a strenuous long-distance running event compared with placebo.¹¹
