No significant differences were observed for vitamin C supplementation or for each 8 h collection interval; therefore, urinary F₂-IsoPs were averaged within each participant over time and vitamin C supplementation. Urinary F₂-IsoPs were analyzed using MANOVA and Tukey’s post hoc where appropriate for pair-wise comparisons. Main effects are listed in the table and pair-wise comparisons within a column not sharing the same superscript are significantly different (p < 0.05).
