depression
"I'm 47 and heterozygous for both MTHFR mutations. I just came out of a deep, dark depression with the help of Effexor. I started taking 0.5 milligrams of methyl folate (yes, a very low dose) about a month ago. Even this small amount of methyl folate (in combo with methyl B12) affects me deeply and immediately. I take it before 8 in the morning, and it still influences my sleep that night. I have never been an active dreamer, but on methyl folate, I dream A LOT. I seem to feel more awake and active in the afternoons, as well. I agree with the commenter about being on methyl folate for a period of time before deciding if it works for you. You may feel the effects immediately, or later on. There may be ups and downs."
