Delayed onset muscle soreness (DOMS) is a multifactorial progression related to muscle pain, swelling, stiffness, tenderness, altered joint kinematics, muscle fiber disruption, decreased strength and power, and acute tissue damage. Curcumin, a natural phytonutrient, could manage DOMS induced by eccentric continuous exercise due to its wide range of biological activities. This study was a randomized, placebo-controlled, double-blind clinical study to assess the efficacy of Cureit™-a bioavailable form of curcumin that may decrease damage from inflammation and oxidative stress associated with severe muscle damage induced by continuous eccentric exercise. The results of the study showed that oral consumption of Cureit significantly reduced DOMS, slightly reduced creatinine kinase concentrations, and slightly increased VO max value compared with placebo, and found safe for administration. The consumption of Cureit led to improved recovery and reduction of DOMS without any side effects due to the enhancement of bioavailable form of curcumin.
