Having a major crash seemingly from adding a few mcg of Metafolin to my protocol earlier in the week. Muscles are unbelievably fatigued and also painful. I knew I don't tolerate any of the folates, but I thought I would try again in case the TMG I recently added would make a difference (serum B12 and folate both measure high). I've been taking potassium caps and drinking potassium broth, but no improvement in the fatigue. What likely happened, and is it possible to reverse this?
