Vitamin B12 dosage?
 

:confused:

I read "Peripheral Neuropathy - When the Numbness, Weakness, and Pain Won't Stop" by Dr. Norman Latov @ 2007

Twice in the book (p. 28, 86) he recommends a daily dose of Vitamin B12 of 500 MG. Is this a typo?! Everything that I have found/read on the net - talks about B12 being measured by MCG not MG's.

**

So, the book's dosage of 500mg is the equivalent of: 500,000 mcgs! I don't have the time or money to take that many pills a day when the largest increment that I can find of B12 is 2,000mcg's per capsule.

Did the good doctor mean to write 500 mcgs of B12 rather than 500 mgs of B12? Surely this is a typo in the book?! Your thoughts?

Thank you.

Welcome readingrocks7. :Tip-Hat:

Someone will be along to help.

Yes it is a typo. I have that book and
Saw that. It is not surprising from a doctor who just
Doesn't understand nutrients. Poor proof reading
Too. Oral B12 really does not deliver much at 500mcg
So 1000mcg is better.

The author didn't even write 500 mcgs - he wrote TWICE, an IMPOSSIBLE dosage of 500 mgs! Thank you for sharing your thoughts! I appreciate it. Somebody needs to contact the publisher and let them know about this mistake. And . . .I wonder . . . is his 5mg of folic acid in the book, is that a typo to?

Can't say about the folic acid.
5 mg is used Rx frequently by doctors, though.

However, new information is coming out
That folic acid ( which is inactive in the body)
competes with activated methyl folate at
the blood brain barrier. So it is better to avoid folic
Form. With all the new DNA testing coming
Out there are more people being found to have
the MTHFR mutation which affects normal
methylation.

It is also not safe to use high dose folic acid
in the presence of low B12 levels. And doctors
Continue to evaluate lab results for B12
Tests wrong and not adhere to the new
low of400pg/ml (many still call 200 "normal").

Methyl folate is available as Metafolin by
Solgar at iHerb.com and on Amazon.
I think Swanson's has it generically now,
too.
