Ascorbic Acid Supplementation Improves Skeletal Muscle Growth in Pacu () Juveniles: In Vivo and In Vitro Studies.

In fish, fasting leads to loss of muscle mass. This condition triggers oxidative stress, and therefore, antioxidants can be an alternative to muscle recovery. We investigated the effects of antioxidant ascorbic acid (AA) on the morphology, antioxidant enzyme activity, and gene expression in the skeletal muscle of pacu () following fasting, using in vitro and in vivo strategies.
