Re: Iodine absorption through the skin? (transdermal)

[Guest guest]

I have used Povidine (Betadine) iodine on the boils on my skin and finished the boils

in about seven days. They were five boils. I dropped three drops of Povidine directly on the

mouth of the boils and left it there for a minute before scrubing it with cotton.------------Ratan Singh, Phone: 91 141 2652561, mail: ratanpsych@...- Certificate in Food & Nutrition; Diploma in Nutrition and Health Education.- Author of "Nutrition & Supplements in Major Mental Illnesses";- M.A. (Psychol), Postgraduate Diploma in Medical & Social Psychology, Ph.D.;- Certified Behavior Therapist (from late Prof. J.

Have any of you tried to supplement iodine solely through the skin? I have successfully used transdermal magnesium using Epsom Salts for afew months now, and was thinking, that transdermal application ofiodine may be similarly effective.Are there any studies showing the absorption and bioavailability ofthe various iodine compounds through the skin?One reason I'm considering the transdermal route is, because the oralforms of iodine are very difficult to find in the Philippines andwould be a hassle to get through customs, if mailed from the US.The only oral iodine products I can find here are Kelp with only225mcg/tablet and Jodid tablets with 100 micrograms (not milligrams)of potassium iodide. For external application I can getPovidone-Iodine (Betadine). The manufacturer of Betadine listsPovidone-iodine 10% (1% available iodine), which according to othersources is equivalent to 2

mg of iodine per drop of Povidone-iodine.If I would use Povidone-Iodine on the skin, how many drops would Ineed to apply to get the same dose of iodine into the body as a 50 mgIodoral tablet (considering transdermal absorption and bioavailability) ? Christian

-Dear Group,

I too have been painting with Povidine-Iodine for about a year now,

and am wondering how to get the dose to match the 50 mg of Ioderal. I

do sleep better on nights that I paint on the the 3-4 inch square of

iodine on my stomach area. Does anyone have advice for us?

I found two older posts which give a little bit more insight into this

question:

" Re: Transdermal absorption of iodine -- Gottardi "

iodine/message/2518

Re: Re: Patch test

iodine/message/6966

Gottardi states, that " povidone-iodine preparations which have

substantially ***lower*** free iodine concentrations (2-10 ppm) than

Lugol’s solution (approximately 170 ppm). Nevertheless, since

povidone-iodine preparations can also cause an increase of

serum-iodide, iodine from these compounds must be absorbed by the skin. "

The book is online at:

http://iodine4health.com/research/gottardi_1995_uptake_and_release_of_iodine_by_\

skin.pdf

From the above it seems that much less Iodine is absorbed from

povidone-iodine preparations than from Lugol’s solution. Gottardi

never gets into how much is absorbed systemically into the

blodddstream. So this still does not answer our question, but it seems

it would be a better idea to paint with Lugol's, if we want more to be

absorbed into the body.

I believe tincture of iodine 2% or 7% may also be better absorbed into

the body than povidone-iodine, as it would be somewhat similar to Lugol's.

It would be important to know, whether for example 50% of the iodine

is absorbed from the skin into the bloodstraem or maybe only 5%. Has

anyone found any absorption studies regarding these iodine

preparations which could make this a bit clearer?
