I have MTHFR and have been taking methyl B12 for a few months now. Also, labs had shown I had a functional deficiency. Within the last few days, I have had symptoms of low potassium. I've supplemented with potassium which helped greatly. I know potassium is needed when new cells are being formed. I searched here but was not able to find an answer to this. Will I need to take potassium the rest of my life or will the need decline as new cells being formed level off?
