+- In a randomized double-blind controlled trial of 76 postoperative colorectal cancer patients, six months of Lactobacillus supplementation was associated with higher serum catalase and glutathione and lower oxidized glutathione and 8-oxodG compared with placebo; F2-isoprostanes were also higher, so the oxidative-stress marker findings were mixed.[^3]
