I seem to have a problem tolerating B12.
When I initially began supplementing with methyl B12 (Jarrow sublingual 5000 mcg), I chewed one pill in the morning on an empty stomach without problems. The B12 was a HUGE help to me. I’ve been suffering from mysterious, often severe pain in the shoulder and collarbone areas, as well as odd symptoms in my feet: burning, tingling, pulsing, painless muscle twitches that are also in the calves, and increased sweating.
The B12 caused both the issues in my shoulder and feet to vanish! I was 100% better. I also felt less tired. Alas, a little over one month after I began to take the B12, I started experiencing shortness of breath and an increased heart-rate. At first I didn't make the connection.
Fast forward a good five months filled with useless doctor appointments in which they told me I had anxiety, and I FINALLY figured it out. It was the B12! Within 30 minutes of taking a B12 pill I start to get short of breath. Sometimes I REALLY have to gasp for air; I just feel like I’m not filling my lungs properly. As you can imagine, it’s extremely uncomfortable and frankly alarming.
The problem is, without B12 the terrible pain in my shoulders came back with a bang, and the problems with my feet are slowly creeping back as well. Today, quite frankly, sucked big time in regards to my symptoms. Was pretty much falling asleep in the car on the drive back from work today. Not safe!
After talking to some people in another forum who thought I might just be sensitive to methyl B12, I bought Perque Hydroxocobalamin sublingual 2000 mcg pills. I let one dissolve under my mouth instead of chewing it. Unfortunately, I had the same exact issue with them as I did with the Jarrow B12.
I don’t understand why B12 seems to cause these problems. I’ve found a handful of people online who describe the same side effects, but all in all this seems to be an unusual reaction. Most sites say that B12 is well tolerated by the average person. For reference, my B12 level before I began supplementing was around 490, but the doctor did a standard blood test versus a urine test (I’ve heard the latter is far more accurate).
Does anyone have any advice? I’m lost, and none of the doctors I see seem to know ANYTHING about B12 or vitamins in general. They’re clueless! I'm having an MRI done on my neck soon to see if they can find a specific issue, but I'm dreading it. God knows it'll show nothing and I'll be back to square one, unable to get a diagnosis and unable to treat myself. I so badly want to take B12 and feel healthy again, but I don’t know what to do! Should I try Cyanocobalamin? I know people badmouth it, but I’ve already tried the preferred methyl and hydroxyl B12…
