Overlaid vitamin intake distributions from lactating (n = 180, dashed curved line) and non-lactating (n = 342; solid curved line) women assessed by 24-h dietary recall for vitamins of interest in comparison with the estimated average requirements (EARs). Two-sample t-tests were used to compare mean intake differences for each vitamin: (A) vitamin A (p = 0.62), (B) thiamin (p = 0.69), (C) riboflavin (p = 0.42), (D) niacin (p = 0.65), (E) vitamin C (p = 0.06), (F) vitamin B₆ (p = 0.65), (G) folate (p = 0.29), and (H) vitamin B₁₂ (p = 0.38). Vertical lines represent EARs for vitamins for lactating women (dashed line) and non-lactating women (solid line).
