Ok - I have been reading your website and generally web-surfing.
As near as I can figure, 1 to 5 mg a day is preferred. (I am currently getting a daily total of 4 mg in the 2 daily doses of metanx.)
Sub-lingual seems to be better than pills? And how do I identify an excellent company?
Thank you so very much - you are a jewel!

Thanks!

Make sure you are getting methylcobalamin. There are, in my opinion, unscrupulous marketers jumping on the "sublingual" bandwagon and selling "sublingual" cyanocobalamin for a lot of money. What a crock.

It's been about 40 years now since researchers learned that the large dose 1000 - 2000 mcg (all at once) on treats B12 malabsorption as well as shots. Since then it has been shown that in many if not most cases lab results show even better results with oral. And all that is with swallowed, relatively inefficient, cyanocobalamin.

So just make sure you don't pay a bunch of money for someone's hype.

There are other good brands, but the one I have seen lab results on over the years is Jarrow. Some are pharmaceutical grade, do well consistently when tested independently, etc. Beware of a company that doesn't make the ingredients easy to find or makes it sound like they've got something no one else has.

1000 - 5000 mcg methylcobalamin is the most common range. I think the 5000mcg is a better value, and a person can never be sure that the larger dose won't help more, and after really loading up for a good long while, one might cut back to one every two or three days. Safe and relatively inexpensive, so.....

Thanks - you're an angel!

I so appreciate your sweet comments!

Metanx has 3 unique things ...

Besides the methylB12 it has methylfolate (which is no longer available OTC)

This special folate is for people with genetic failures in folate metabolism. There are 25 newly identified ones. The Merck company greedily decided to no longer sell it to vitamin distributors (in 800 mcg strengths) and to save it for the 2
RX versions -- Metanx and Cerefolin. This is just reprehensible IMO.

Also the B6 in Metanx is activated P5P--- to help those who fail with
regular pyridoxine which needs internal conversion to work.

If your insurance pays for it, I'd keep it. I am thinking of requesting it myself,
if my insurance accepts it, as a matter of fact.
