Adreno how do you know that you need extra B2? Is there anyone here who can advise on B6, specifically in relation to pyroluria hpu/kpu ? I decided that I most probably had it last year. I never took a test as the tests seemed pretty unreliable -- though that was probably unwise of me (have been doing a lot of self-experimentation over here). Anyway, I started supplementing with extra zinc plus manganese in the morning and B6 plus P5P (activated B6) in the evening. It set off huge detox reactions and I had to go very slowly. I am assuming that resistant starch is helping the body to produce B6 - hence the vivid dreams. So, this might be slightly impossible to answer, but should I continue to take the B6's every so often ?? Or should all B supplementation be stopped as the healthy bacteria are starting to produce it? Except for perhaps B2? -- I have very superficially skimmed the 'B2 I love you' thread and know that was the basic theory proposed there, I haven't had the concentration span to understand the mechanics of it yet. Edited to add: My apologies that this is a little rambling and disjointed. In essence I am simply trying to understand how taking resistant starch is changing the Vit B levels. I know that it is increasing B6. And seemingly depleting B2. This raises questions about what to be supplementing with, if at all.
