Re: personal question B6

[Guest guest]

I too am interested in knowing because my doctor saw a Vitamin B deficiency and

prescribed me a B supplement.

Will look up amount and email so I can get some feedback.

Hi ,

Good to hear from you and congratulations on the soon-to-be grandchild! As for

the B6, Dr. Gareth Parry's statement is below. (No more than 20 mg daily, and he

prefers persons with CMT take no more than 10 mg daily)

As a natural anti-nausea product, your daughter may want to give Ginger cubes a

go. Most markets carry it, it can be eaten as is, mixed in food, or made into

tea. I've used it for years when sailing.

Vitamin B6 Use: Current as of 11/11/2004 – by Gareth J. Parry, M.D.

The RDA (recommended daily allowance) of vitamin B6 is 2 mg and the MDR (minimum

daily requirement is 0.1-0.2 mg). The amount in a typical

multivitamin is 5 mg although many have 10 mg and, obviously, some have 8 mg.

There are several products available over the counter that contain 20 mg.

All the research that has been done indicates that all of these doses are safe

for normal people and I am not concerned for my CMT patients at these doses.

Larger dose tablets can be found - there used to be a 500 mg tablet!

In our studies, the lowest dose that we found to be definitely toxic to nerves

was 500 mg daily; we had one patient who was adamant that she was taking only

200 mg daily who developed nerve damage although she was also taking a lot of

B6-rich foods. One doctor in London, England claims that 50 mg daily can be

toxic to the nerves but no one else has been able to show that.

In summary, I tell my patients under no circumstances should they take more than

20 mg daily and I prefer them to take no more than 10 mg daily. 8 mg daily is

certainly safe.
