Hi, I'm following Fredd's protocol and have run into some major difficulties. I have sadly been unable to avoid taking the RDA level of folic acid which comes in my multi but on top of that I have been taking an RDA level of methylfolate contained in the Thorne Basic B Complex and also half of one 400mcg Solgar methylfolate tablet. Along with this I'm taking half a Jarrow Mb12 sublingual and have been building my way up, slowly, from tiny amounts. I realise that I still have a long way to go in order to increase my dosages but I have been really sensitive to these supplements. Right, onto my problem... For the past few days I have had a near-constant angina-like ache in the left side of my chest and have also been suffering from numerous palpitations and heart flutterings. I have also become 'crashy' and feel incredibly fatigued. It is worth noting that my latest blood test results from the GP show 'ok' levels of B12 but high levels of folate. I'm curious as to whether I need to decrease my folate, increase my B12 or start ingesting additional potassium! Can anyone tell me if the symptoms I have mentioned, or the high plasma folate suggests an obvious solution? Many thanks!
