Background Aflatoxin B1 (AFB1) is classified as a Group I carcinogen. A Previous study found that oxidative stress from the metabolism of AFB1 induced hepatotoxic effects in wheat miller workers. Zinc and vitamin C may play a significant role in the activation of detoxification and overcoming the oxidative stress of AFB1. Objectives A prospective clinical trial was designed to evaluate the role of zinc and vitamin C oral supplementation on the oxidant-antioxidant status and the hepatotoxic effects of AFB1 in wheat miller workers. Methods Liver enzymes (ALT, AST, ALP, and GGT), P53 protein, malondialdehyde (MDA), glutathione S transferase (GST), Superoxide dismutase (SOD), zinc and vitamin C were estimated in 35 wheat miller workers before and after zinc and vitamin C supplementation for 1 month. Results The results revealed that zinc and vitamin C were significantly increased after the one-month supplementation, while liver enzymes (AST, ALP, and GGT), MDA, and GST of the workers were significantly decreased. SOD and P53 were also decreased but not to a significant level; SOD was decreased in 56% and P53 was decreased in 58% of the total workers. Conclusions Zinc and vitamin C oral supplementation for 1 month had an ameliorative effect on the hepatotoxicity of AFB1 in wheat miller workers, through decreasing MDA, SOD, and GST levels that in turn led to an improvement in their liver enzymes. Further study on a larger scale is needed to confirm these results.
