Hi,
I am going to change my D3 vitamin with a D3 5000 i.u. sublingual vitamin, and decided I'd like to change to sublingual on my B12 as well. Is there a certain amount a person needs? I've seen 1,000 and 2,500. I'm sure it varies from person to person - just wondering if I could take too much. Last blood level check for B for me was 895 a year ago.
Tks.
Paula

Hi Paula,
The RDA for B-12 is something like 2.5 micrograms. Multivitamins such as Centrum Silver contain something like 10 times that amount (25 micrograms). I take 1 Centrum Silver tablet each day, plus 1 Metanx (which contains 2 mg of the active form of B-12, which is equal to 2,000 micrograms). IOW, I take about 2,025 micrograms of B-12 per day. I assume that the units that you listed are in micrograms, also.
I've been on this dose for almost 4 years now and my B-12 level is close to the top of the normal range. Therefore, either dose you listed would work, even for the long term, though the larger dose would probably put your level at the very top of the normal range after a few months or so. In order to get the maximum utilization of B-12, you need to be sure that you are also getting about 400 micrograms of folic acid. I used to use sublingual lozenges that contained 1,000 micrograms of B-12, and 400 micrograms of folic acid, before I started using the Metax.
It's pretty difficult to overdose on B-12, unless your liver and/or kidneys are not functioning properly, because the excess is excreted in urine. If the normal range used by your lab is the same as the lab I used, then your level was near the top of the normal range on your last test result.

Thank you for your response, Tex.
Since it may be possible I am already getting enough B's, I may hold off on changing that (at least until after my next blood work which I'll have done this summer).
Thank you for helping me better understand this, and for letting me know that the range it was at last year was in the top range. I'll save this useful information for after my blood work.
Hope everything is going well for you with your health, and also hope the weather is being good to the Texas farmers. Wisconsin has been too wet for farmers to get all their crops in.

Paula,
You might check the normal range on the test results when you get them, just to be sure, but I believe that the upper limit for the normal range on the test that I had was around 940.
Health-wise, I can't complain. I'm probably doing better than I deserve.
It's still dry as a bone down here (we're officially classified as under extreme drought conditions here where I live), but amazingly, we just happened to get a few rains at just the right time during the spring, and so the crops around here will be at least somewhat decent — much better than last year and the year before.
The weird part is the temperatures, and that helped the little moisture that we had during the spring to go further. We broke low temperature records almost every month since February, except for June. Last week, our high temps were mostly in the 103 to 109 range, for most of the week. This week, we have a norther blowing (something that never happens in July) and our highs are quite comfortable for July (in the upper 80s, but the air is very dry). The interesting part is that due to the dry air and the norther, we will probably set a record low temp tonight, and there is a very good chance that we will set an all-time record low temperature for the month of July, before the week is over. Lows in the 50s have never happened here in July, since anyone began recording temperatures (over a hundred years ago), but we will almost surely see lows in the 50s at many locations around here for the next several nights.
