The physiological effects of creatine supplementation in fetal sheep before, during, and after umbilical cord occlusion and global hypoxia

Direct fetal creatine supplementation increased plasma and cerebral creatine concentrations but did not alter fetal body weight, basal cardiovascular output, or blood chemistry. Creatine-treated fetuses displayed changes to arterial oxygenation 24–72 h after acute global hypoxia. An increase in striatum total creatine levels following UCO was also noted and suggests that increasing creatine tissue availability may be an adaptive response against the effects of hypoxia.
