* ATTENTION: STEPHANIE, Re: Lugol's and Optimal Concentration!

October 16, 2011

Megaera,

Thank you for your post here and for taking the time. I remain confused however

on a couple of things.

First, you cited the " MSDS " of J. Crow's formula as below, but the ratio I read

on their site was a clear 1: 1 1/2 ratio NOT 1:2.

Furthermore, voiced some concern about J. Crow's Lugol's.

So WHAT is the premier source or manufacturer bar none of Lugol's Iodine.

Simple question. I don't know why this has to be so confusing. And why is J.

Crow's in question in the first place?

WHAT's the BEST Brand, Manufacturer or Supplier?

Thank you, Trisha

health purposes, but insofar as Lugol's formulation is concerned it is a

chemical formula only, developed for use in reagent research and simply has his

name attached for convenience, so there are no " proprietary " issues -- it's just

what the formula is called. As far as J. Crow's Lugol's formula is concerned,

their MSDS shows a ratio of 5% iodine to 10% potassium iodide and their water

concentration is appropriate for 5% Lugol's solution. If your question arose

over omitting the potassium from the formula to get that 1:1.5 calculation,

remember that Lugol's HAS to have the compound potassium iodide as its second

part, because without the potassium iodide the elemental iodine will not

dissolve in water. Omit the potassium from anyone's " Lugol's " formulation and

you will probably wind up close to (plus .5 parts potassium), but it's never

written out that way because the potassium iodide is already in compounded form.

in the past about how much of their product to take, but if you use per-ml or

per oz content estimates appropriate for the percentage strength Lugol's you are

using and make correct droplet counts for your dropper the company's

formulations are as usable as any.
