MTHFR, Folate and Liver

I have high Histamine (when a doc tested serum histamine), this correlates to undermethylation. I notice when I have red meat, I feel cognitively much better. This is something that’s only recently started to sink in. I was listening to an ATP podcast, possibly one on MTHFR and they were touting the benefits of liver. I think I remember Mark Sisson talking about blending liver raw? So I cooked up some liver from an online recipe. yes. Success. This will now in one way or another be a staple in my diet. Possibly I might try blending in a stirfry…

I still don’t totally understand the whole process.. but the words methionine and homocystine came to me after I ate this liver and felt great… I think methlyation turns homocystine into usable methionine? or something…?

Edit: Well well well…
“Folic acid (folate) is one of the ‘B’ vitamins that is needed to metabolise homocysteine.” – I believe Liver was mentioned to be one of the best sources for folate in that podcast. Reading up on MTHFR and they mention that an issue is “converting folic acid (or more precisely 5,10-methylene tetrahydrofolate) into 5-methyl folate.” Which I think was one of the issues mentioned in the ATP episode… So potentially that may mean I have a MTHFR C677T block if liver is able to supply me with folate I am unable to convert from folic acid..? Also I was cooking this liver with a bunch of garlic and onion, possibly contraindicated
