Have you tried taking methionine?
I've tried taking methionine, but that was because my methionine was low. I was prescribed 1500 mg/day. My homocysteine was in the bottom 20% of the normal range.
Another change was made at the same time, and that was NAC. Of course, being histamine intolerant but not knowing it, the NAC was terrible. I thought it was both the Me and and NAC, or sulfur in general. Later, when I tried only Me, I was fine.
However, I read something about rats not living as long when you gave them Me - I don't think there were enough parallels between the study (they may have had other conditions like malnutrition or something) and me to really worry, but I decide to switch to SAMe, and my NP supported it. She said 400mg, so that's what I've done. I have
a lot of the ATP5c mutations, so I maybe don't want to waste ATP on converting methionine to SAMe. But then, I don't want to waste money, so maybe I'll go back to Me.
I also added TMG, to recycle homocysteine to Me, since my BHMT-08 was +/+, but that lowers homocysteine, so maybe you don't want to do that if your homocysteine is below low-normal.
