Towards the end of the tour (in Austria) I noticed leg cramping that I had never experienced before, mostly in the evenings after the days ride.
I very often get symptoms of low potassium in the middle of the night. And I know I must have gotten depleted earlier in the day to have the symptoms middle of the night. I take 300 mg. potassium gluconate 4 or 5 times a day and the other day I missed two doses and that night, middle of the night, woke up with a very painful spasm in one of my ankles/feet. I quickly drank a large glass of tomato juice, managed to go back to sleep, and an hour later woke up with a spasm in my other foot! So I drank more tomato juice. This seems to be a pretty quick way to get potassium into my system without a lot of sugar.
However, supplementing is not going to be easy because potassium supplements are limited to 100mg per tablet. I need something to be portable.
You're right, they are limited to 100 mg. per tablet. I take a ton of supplements in addition to potassium, so I use 7 day vitamin dispensers like
this. And I just take it with me when I go somewhere. (I always wrap it in a plastic bag as the slots can flip open)
I take a handful of things first thing in the morning (various aminos) (the first slot in the dispenser), then more pills post-breakfast, including potassium (second slot, etc.), then more aminos before or after lunch, and more regular vitamins, potassium, etc. after lunch, etc. etc. It's ridiculous the amount of stuff I take but it all seems to be necessary.
I've read it's not good to take a huge amount of potassium all at once - so I divide mine up. I think I mentioned this but I had to titrate up to find out how much potassium I needed. Actually a few months ago after doing well for quite awhile on 800 - 1000 mg. of potassium a day (in divided doses), I started getting low symptoms again so I increased it to 1200 - 1400 mg or so. fwiw, on blood work my potassium is always in the normal range but it's always on the low end of normal. I would not be at all surprised if I were one of the people with ME/CFS who has low intracellular potassium despite normal blood work.
Thinking that I might be undermethylating (I have 1 copy of the bad A1298 gene)so I took another methyl folate pill with 850ug of methyl folate. Surprisingly my muscle pain symptoms got worse!
Actually, I don't think this is surprising. If you have a folate or B12 deficiency, it can trigger a refeeding syndrome reaction, like I described above , when you start to remedy it. The extra folate may have caused your potassium to tank (refeeding syndrome), resulting in muscle cramps, pain etc. And if this is the case, it means you actually need that extra folate. When your body starts to utilize a missing nutrient like folate which is being suddenly being introduced, it requires more potassium to do this, resulting in a functional potassium deficiency.
I'm not that knowledgeable about methylation but I'm very familiar with low potassium and refeeding syndrome. Actually I developed refeeding syndrome when I started taking B1 several years ago, but that time it caused my phosphorous to tank instead of potassium. It took too long and too much detective work to figure this one out. Anyways, I had to start taking phosphorous and now I take that almost every day too!
If I were you, for now, just to make things simple, I wouldn't worry about overmethylation. I'd go on the assumption that folate has caused your potassium to drop at various times (which means you need the folate). I'd keep low-sodium V8 or tomato juice on hand to drink a couple of glasses when you get muscle pain or cramps. And see if it helps. And then you can decide whether you need to add a potassium supplement.
o is there something in the B-Minus supplement that is messing with my methylation cycle?
I don't think so, but it may not be the best supplement for you because it doesn't have folate and B12.
BTW, how did you fix your high MCV?
Good question. I haven't been tested for a few years, I moved a couple of years ago and replaced my old doctor. I like the new one but he's not really a PCP. He'll do things I ask (like certain testing) so this is something I need to ask him to do. One of these days I may get a regular PCP though they are generally pretty useless as far as ME/CFS is concerned.
Anyways, high MCV is generally caused by low B12 and/or low folate. I take methylfolate daily, and methylcobalamin several times a week. I can't remember if I told you but when I first started the methylfolate, I had an amazing day or 2 of energy, and then got hit with severe fatigue, low potassium, etc.
https://www.testing.com/tests/mcv-t...s that the,vitamin B12 levels or chemotherapy.
- High MCV means that the RBC are too large and indicates macrocytic anemia. This condition can be caused by several factors including low folate or vitamin B12 levels or chemotherapy.
So I would assume that your high MCV is caused by low folate and you may even need more B12 too but I would concentrate on one at a time. If your potassium is tanking when you take folate as evidenced by muscle cramps and any other symptoms of low potassium, I think this is evidence you need the folate, and extra potassium.
