Some years ago I discovered that a B12 shot in the evening, when I was no longer going to be exercising, invariably led to leg and foot cramps during the night. If I did 5 minutes of exercise on my Gazelle after a B12 shot in the evening, then I experienced no cramps during the night.
Later I discovered that a B12 shot along with a magnesium tablet banished the cramps, just as efficiently as exercise.
The cramps aspect of using vitamin B12 surprised me ~~ My original research into vitamin B12 indicated that there was no danger of taking too much B12, and it was therefore harmless.
In any case, for several years I used 5 or more of the 5mg Methylcobalamin lozenges a day. That was about how much I needed in order to not have nose bleeds, feel depressed or have numb feet, among other symptoms of low B12.
Then I hurt my back and each time the pain woke me during the night I used another 5mg Methylcobalamin lozenge. I believed it helped with the pain.
It may have helped but in not too long I was getting painful muscle spasms that affected not just each leg, and all of it, but also my torso, which was rather scary. I hated to think it was possible to take too much B12, but I stopped using so much.
It was also at that time that I discovered that B12 comes from micro-organisms and that B12 is plentiful in the air and soil. In my reading about B12 originating with micro-organisms I started thinking about how B12 is characterized by its cobalt content. So, I thought, perhaps I have a build-up of the heavy metal cobalt.
With that I looked into what is used to get rid of heavy metals. Turns out it’s cilantro. I ordered two bottles of cilantro capsules on August 12, 2012 and took them religiously when they first arrived, and for several months thereafter. I also used Milk Thistle, with the thought that if the cilantro was clearing out the heavy metal, I didn’t want it all stuck in my liver.
Today, I’m almost completely fine, and using 5mg Methylcobalamin a day.
B12, Muscle Spasms and Potassium
Sometime after reducing my B12 intake I once again began having peripheral neuoropathy pain that kept me awake far too much of the night. Admittedly it was after a lot of stress when I hadn’t used additional Methylcobalamin. (In fact I was getting shingles).
At the same time I’m not sure how much B Complex to take to keep from having allergies now that I need far less B12 after switching to organic food from GMOs ~ See September 26, 2012. B complex, you see, contains folic acid and that interferes with B12 absorption.
After I tweeted about my February 6th blog regarding B12 replacement and muscle spasms I received a response that mentioned excessively low potassium, known as Hypokalemia. Apparently hypokalemia is reported by many people as a complication of vitamin B12 replacement after deficiency. This is because B12 normalizes blood cells so that they once again grow properly and divide properly, which takes large amounts of potassium, thus depleting circulating stores of the mineral.
Now, there’s a lot of potassium in bananas, potatoes, and other foods. But, if you’re not eating them, or are eating processed varieties, supplements seem like the answer. Except after a lot of looking-for-the-best I found that 96mg was about what I could expect from a tablet or capsule ~~ We need about 4,700 mg a day.
I learned that the bicarbonate form of potassium helps alkalize your body’s pH. This is in marked contrast to a chloride form that is acidifing. Potassium in fruits and vegetables is the bicarbonate form. It is wise to avoid potassium chloride. (More information on alkalizing vs acidifying.)
Potassium citrate is readily absorbed, improves calcium balance, and slows the crystallization of calcium-containing kidney stones. Potassium aspartate is already bound to aspartic acid which activates energy-rich phosphates. I’m ordering… Today! And I did, but I never opened them because by the time they arrived I’d learned about Maca and other foods containing potassium.
