I had some blood drawn earlier this week to see if there was another reason for the fatigue other than MS

They tested the thyroid, b12 and a CBC.

I just called and they had the result of the b12 test.

It was 340. Last time I had it checked (probably 2007) it was 345.

They told me it was normal, but stuff that I've been reading says that it's a low normal and could still cause neurological stuff.

I think I'm going to go buy a bottle of b12. It's not like it'll hurt me to take some every day.

B12 500 mcg 1 a day keeps my level at top of range along with a B100. However, try it and get checked a month from now because people in Dr's office last week were talking B12 injections they take (didn't know dose) because they said their body doesn't have the ability to take it in orally.

Yes, this is low, but not really low... 400 is the cut off here and 500 in Japan. But you are borderline, and have a neuro disorder. That alone should qualify you for supplementation.

I'd do methylcobalamin 1000mcg a day on an empty stomach.
This is the active form, and does not need activation like cyano does.

This is my B12 thread that explains it:

Doctors still remain clueless on oral, and active forms. So please do read up and take advantage of the low prices you can get on the best form, methylcobalamin.

I take 1000 per day...my B12 was really low...the old neuro thought it was causing my cog fog...nah...it's the MS. But I take it anyway.

I take 1000 B-12, like Mrs. D. does. I take 500 in the morning and 500 in the evening. Due to some lacking in my gut absorption.

Years ago it was so low I couldn't get off the couch, after giving birth. Never had that before, thought it was a relapse. I usually bounce right into normal activity.

I was tested, my B-12 was so low my GYN dr started giving me a B-12 shot weekly at his GYN office.

Funny after a few days I could feel it wearing off. I couldn't wait for the next hip/hinny shot. I had energy to spare. I don't know the dose, I was young and didn't even ask any questions about B-12 levels. I just believed in my doctor.

I was fine in no time at all, off shopping and out and about with three kids. Who knew?

I was told by that GYN to take oral 500 B-12 for the rest of my life. I took that amount until 2002, then I upped it to 1000 per MS doc. My blood work is 700-900 for B-12. I rather be high than low. I don't know how much my gut absorbs, but the blood is fine.

Now people give themselves B-12 shots. My last Neuro, in 2005, had his daughter give it to him. I laughed at him.

I said, you give other people MS meds to inject themselves, he had me on "C" at the time, and yet you are needle phobic to give them to yourself? He said, he can give them, but hates to do his own. Huh??

B12 has never been a problem with me; however, I thought a sublingual B12 was the best administration of it next to injections. Pills and tablets reduce dosage absorption down to 25 to 35 percent.

I can understand then why one would need a twice a day and 500mcg dosage taking that into consideration. My knowledge regarding B12 has diminished greatly over the years now.
