(A) Representative EPR spectra from blood collected from subjects that received either placebo or N-AC. The EPR amplitude (arbitrary units) is directly proportional to the amount of free radicals in the sample. (B) Summary data of EPR amplitude from subjects that received placebo or N-AC at the pre-ingestion, post-ingestion, and hAIHT time-points. ANOVA main effects P values are provided in the top left. Neither hAIHT nor N-AC altered the concentrations of circulating free radicals in peripheral venous blood in the study subjects.
