How are you noticing the B2 is helping with iron in the liver and thyroid?
Energy. It's kind of subjective at this point.
I am chronically anemic due to heavy monthly blood loss, and don't have too many symptoms from that that I am aware of, but I have been so chronically anemic for so long I probably wouldn't know if it was causing me symptoms with my energy since I "get by" even when my ferritin is very low. The anemia also seems to be more "paradoxical", in that ferritin is low but other lab values for anemia are normal. Low normal, but still not bottomed out like ferritin. That fits with some of what Dog Person wrote early in this thread about we don't necessarily have to have anemia values to have anemia if it's being stored in the liver and/or not utilized properly, and that low ferritin isn't necessarily a sign of low iron. Just low iron transport. Etc.
But...I also recently (within the last few months) experimented with some niacin, which definitely had a deleterious effect on my energy. I've not been quite right since. Turns out that little bit of self-experimentation affected my thyroid negatively, according to my latest lab values. Past few years my TSH has always been <1 when tested, but this past test earlier this month showed it had gone up to about 1.19. First time it's been above 1 in a very long time. I wasn't surprised at all because I could feel that my thyroid wasn't working quite right. But since taking the B2 (and manganese) my energy has improved back to where it was before the niacin.
So, again...kind of subjective. We'll see where ferritin and TSH are in another couple months. But based on how I'm feeling now, I expect them to be improved if I continue like this.
How does the methylfolate help you? What sympoms does it alleviate? What's your high dose?
Freddd's methylation protocol has helped me with pretty much everything. Gave me my energy back. Detoxed me. Helped get rid of the worst of my food cravings. Gave me hope that I might actually be a normal person one day. Gut therapy is the other thing that works synergistically with methylation protocol...after a solid year of methylation, starting gut therapy (pre- and probiotics) stabilized and increased my energy further, plus helping even more with food cravings and overeating. It's all been a process.
High dose for methylfolate was 50mg/day for a few months. I've tapered off that and had to increase again, etc. It's a balance. I dose according to my symptoms. The right amount of mB12 every day being crucial to maintaining balance, I think esp. with MTRR mutations.
As far as B2...I'm using about 200mg of that per day. I take 50mg oral with each meal (when I also take other supplements that are supposed to use up B2), and the rest is sublingual FMN. The sublingual tastes like ass, but it seems to work.
Another interesting thing is that my urine color is getting lighter yellow even though I'm on these high doses of B2. I'm taking that to mean my body is using the B2 better. Any time previous when I would take B2 I'd get this deep yellow urine, even if it was just a smallish dose in a multi-B complex. Now that I'm high-dosing my pee is a lighter shade of yellow.
