Circulating Unmetabolized Folic Acid: Relationship to Folate Status and Effect of Supplementation

Table 6

Estimated dietary folic acid intake (μg/day).

	Week 0	Week 30	𝑃 (week 0 versus week 30)
1.1 mg	221.5±93.9	218.9±93.4	>0.99
5 mg	194.3±82.8	230.1±116.3	0.22
𝑃 (1.1 mg versus 5 mg)	0.78	0.99

*There was no significant effect of time (𝐹(1, 36) = 1.65; 𝑃=0.21), group (𝐹(1, 36) = 0.08; 𝑃=0.78), or time-group interaction (𝐹(1, 36) = 2.19; 𝑃=0.15).
