I love this thread and am up to page 29, myself. There's such a fine dramatic arc with
@Asklipia 's eye problems and gradual healing, as well as Christine Dog Person's fine work, disappearance and possible illness. It's riveting, not to mention informative.
I've known B2 is important, known that it was the ONE B vitamin that my only NutrEval test of about a year ago showed me VERY LOW in, but hadn't fully understood that it was very likely the infamous Country Life Coenzymated B Complex I must have taken for over a decade (YIKES!) that combined a mix of those basic Bs in identical 50mg amounts, with the exception of 800 mcg of Folate to 400 Me B-12 (also not a good idea, as we know via Fred) that no doubt over-taxed my B2 stores. This and almost no dairy for 15 or 20 years. (SIGH!)
How easy it is to shoot yourself in the foot by just following well-intentioned advice/practitioners.
I tried small amounts of the Source Naturals FMN last summer as I began to get into Freddd's protocol, got as high as 1/2 per day in 2 doses and then, once I re-introduced the low-dose B-Minus B complex, I let it drop. I was having a hard time reading anything that was going on in my body at that time and I figured I was getting 20mg of B2 in the B-Minus.
Over the next 5 months I increased B-12 and Folate to 6,000mcg and 2,000mcg respectively. Amazingly, almost all my joint pain disappeared, but my sleep was only marginally better. I had one or two nights a week where I got about 7 1/2 hours of disjointed sleep, but most nights were not that good. There were many nights when I felt plagued by 'wild mind' and would resort to Niacin to slow things down. Those nights were still a disaster and the next day would be a bust. Just more time lost. Slipped away.
It was Greg, the B-12 Oils guy, who took a look at my OAT Test results, saw the high Glutaric Acid (in a range of .04-.36, mine is VERY HIGH @ .55) and said I needed B2. In fact, "High glutaric acid on the Great Plains OAT or on the Genova Diagnostic Metabolic Analysis Profile indicates low B2." (richvank, March 18, 2012, I believe on this thread). So, I started with the FMN once again, this time more slowly--1/4 tablet a day for the first week, increasing by 1/4 each week. I cut back on the B-Minus for the time being, so as not to tax my low levels of B2-at 1/2 capsule in 2 divided doses (12.5mg B1;10mg B2; 90mg B3 Niacin; 10 mg B6; 250mcg Biotin; 75mg Pantothenic Acid--I know these are low, but for the moment I just want to keep them there so i can be clearer about the effects of the B2).
Slowly, I have been pulling back on the MeB12 and Folate (now 3,000mcg and 1,000mcg/day) and will/may go lower still.
I did not have an easy time beginning the FMN. I had a few early nights of crazy black sleeplessness--possibly the release of iron-stores in my liver? But very quickly my sleep began to improve. And the neurological symptoms of tight muscles in my face, or aching of the Dupytrens contracture in my left hand began to subside (Issues I always thought had to do with folate deficiency--and who knows, may, but the B2 may be helping me metabolize more folate). Pain in my calf disappeared when I upped my FMN from 1/4/day to 1/2. So little for such a big effect! I'm still up and down every night, more frequently as I increase the FMN--often every hour and a half. But I spend fewer hours wide awake, not 3-5 hours, only an hour or two. And as noted by Asklipia, I tend to wake earlier.
I am more tired all the time, though less exhausted--if that makes sense. I take more naps and sleep a bit more during that time. Usually 30-45 minutes.
This tiredness brings me to a question I have for those of you who have benefited by this protocol. I am not taking manganese. Mine was normal on my NutrEval test and I'm reluctant to just add things at this point (in fact, I'm beginning to feel more like
@brenda who I think believes we ought to get most of what we need from our diet). My thyroid levels are smack in the mid-range for all the tests, but I have been eating 2 Brazil Nuts a day with no huge disruptions where I couldn't tolerate selenium.
But how many of you are taking extra iron? Or heme-iron as the more utilizeable form is called. "If you have a high ferritin it is reflective that you have very high stores of iron in the liver. Same can be true of a very low ferritin - which I had and was actually more serious than a high ferritin. The hair charts show that the liver is malfunctioning at manufacturing adquate amounts of the carrier protein (transferrin) for iron and the carrier proteins for copper (ceruloplasmin, hepcidin) and binding those minerals to them." (Dog Person, March 18, 2012)
My ferritin, tested a year ago was 81.72 in a range of 16.-204. I thought that was fine until Greg at B-12 Oils said it was very low, and when I called a woman at Proferrin, as small company in Colorado, she said that her levels post hysterectomy were 220 after having been very low. Apparently the reference range used at the Mayo Clinic is:
For men, 24 to 336 nanograms per milliliter (standard units) or 24 to 336 micrograms per liter (international units)
For women, 11 to 307 nanograms per milliliter (standard units) or 11 to 307 micrograms per liter (international units).
So, how do we know if we ought to supplement or not? Or whether our livers will begin to release the stored iron it holds as well as nudge our production of hemoglobin:
"It [riboflavin] contributes to the normal metabolism of iron. Iron metabolism is impaired in riboflavin deficiency. The utilisation of iron reserves from the intracellular protein ferritin requires riboflavin. Riboflavin is required for haemoglobin synthesis." (I'm not sure where this is from, sorry...)
All this said, my higher levels of pain have returned and I have more muscle weakness. I'm just trying not to jump to any conclusions, to go slowly, to be patient, to wait and see how things go as I increase my B2 levels.
And to have some yogurt every day!
One last note: within five days of starting the B2/FMN, I got my first cold/flu in 5-7 years (I can't recall the last one) and continue, two weeks in, to have a runny nose and occasional cough. The mucus is flowing--a good thing.
