Sasha, I've been on the SMP since April, and have had no results. Although Rich thinks heavy metal toxicity might be blocking me, he thinks it's a good time to try Fred's protocol. So, Fred.....I've stopped all sources of folic/folinic acid as of today. Yes, including Wahls' smoothies and kale chips. Since I'm not starting up your full protocol until Monday, I could do your methylfolate test. But I don't understand what it is/how to do it. Could you give me a rundown, or a link?
