Plasma homocysteine concentration after 2, 4 and 6 months of treatment with water, methionine 0.5 and 1% solutions.

<p>(N = 9–11). CT = Control. M05 = Methionine 0.5%. M1 = Methionine 1%. * = <i>p</i>≤0.05 (Tukey's <i>post hoc</i> test) when compared with the CT group at the same period. # = <i>p</i>≤0.05 (Tukey's <i>post hoc</i> test) when compared with the M05 group at the same period. Data are presented as the mean ± SEM.
