Vitamin C Forum

hi there
help required please
have run out of money to buy the vit c so have to make

i have
sodium ascorbate powder
water for injection
ringers

however, am finding it hard to locate the edetate disodium injection, USP 150 mg/ml,
'If Storing the Solution, EDTA acts as a preservative to prevent vitamin C degradation.'
Foundation's updated version of Dr. Cathcart's written IV/C prep instructions: http://www.vitamincfoundation.org/pdfs/civprep.pdf

I would like to store for 2 IV a week
so imagine i need EDTA as that means the next day or two doesnt qualify
'If using in the next day or two, this step would not be necessary.'

also, after reading -

Calcium Disodium Edetate VS Disodium Edetate for IV C,Urgent

"When he says Disodium Edetate does he really mean it?
it seems to me that Cathcart means Calcium Disodium Edetate and not the Disodium Edetate"

i am not even sure which to buy

can you please say which is right
and then, any ideas where to buy, i am in the uk

thanks very much as ever
