New member Dog Person, has looked at my Doctors Data hair mineral results from a test done two years ago, and told me she thought I had a riboflavin deficiency. Apparently, it can develop when there is an extra call on it, for example, when synthetic folic acid is not being converted to folate, when using vit C and Vit D. She also thought that I had a build up of iron in my liver which needs riboflavin to utilize, in fact many processes are dependant on riboflavin. Because flour products are fortified with folic acid, this is a source of trouble for some/many and many B complexes contain folic acid. I felt a difference from the first dose of B2. That night I slept for a full 6 hours, had less trouble opening my eyes (dry eye syndrome - one symptom of B2 deficiency) when I woke, I have more energy today and feel somwhat cleaner inside with a lifting of brain fog. My body feels more relaxed and I had a very deep afternoon sleep today. I am astounded to have such a result in such a short space of time from such a low dose of a vitamin and I have been reassured that I will continue to improve though there will be consequences of circulating iron as it needs to be discharged. It will mean that my body will be better prepared to start the methylation protocol. I was very sceptical about hair analysis since I heard of others who had differing results from the various labs they sent their hair to, but I am now a convert. Many thanks to Dog Person who will hopefully explain it better.
