So in theory, if taking mb12 and methylfolate and potassium, taking more b2 can reduce need for methylfolate and potassium -- which is not necessarily contrary to Fred, but rather he argues there is a point where more b2 has the opposite effect and increases need for potassium and methylfolate.
It is all very complicated and I think I must ask Greg about the relationship potassium has to his particular protocol.
You're right, Fred believes that the higher the lower Bs--B2, say--the higher need (
insatiable is his word) for potassium and folate. Like you, and many here, I've been very sensitive to all supplements and approached this with caution. I'm also on a very low dose beta blocker which can increase potassium levels. If we are following the Fred Protocol, irregular heartbeats have two basic causes--low folate or low potassium--so when the symptom shows up, we try one or the other. Or both.
Which is what I did last night. First the extra potassium, 300 mg gluconate in 1/2 tsp., then a half hour later when my heartbeat was still a bit wobbly, 200mcg of folate. I've only recently increased my folate levels after holding them to about 800mcg/day for quite a while. So, just up to 1200mcg folate, with this extra 200 and within a half hour I was so relaxed, but I realized very quickly, not in a comfortable way. My heartbeat was VERY SLOW, my chest felt heavy, like someone was sitting on it, and I felt like I might just stop breathing.
That was enough to give me a shot of adrenaline! I spent a while on the phone with an on-call nurse and learned one antidote to high potassium levels - water. I may also have been a bit dehydrated as I'd been racing around all day (the result of .6 squirt of the B12 Oils, maybe too much for me still). So I just stayed awake, reading most of the night, and in the end, had to take a tiny dose of valium to help me let go of the hyper-state I'd put myself into. All for 2 hours of sleep.
That said, I'm still kind of shaky and feeling that the whole irregular heartbeat episode might not have been either a need for potassium or folate, but rather the adrenals waking up, as has been reported here lately, I think. Part of Greg's protocol, where he has us having 3 Brazil Nuts/day to stimulate the thyroid with their selenium. For me, the extra thyroid stimulating hormone my be too much as my thyroid has been functioning well within normal ranges. My cardiologist said she'd never give me anything to stimulate my thyroid because of my tendency toward irregular beats, so it may not be a good part of the approach for me.
But of course, it could be something else entirely. The adrenals waking up. And I think that is the B2. (Please chime in, those of you who know better)
So, there you are, another quagmire. For me, no Brazil nuts today! And just 3-5,000mcg MeB12 in the old Enzymatic lozenges! (Oh, and I'd lowered my B2 levels as I've been trying to figure this out--to about 30-35mg/day)
