Re: Iodine fountain of youth?

lipid(fat) peroxidation increases with aging. Idothyronines inhibit that peroxidation.

Remember the article you posted on gray hair and peroxidation?

What I glean from this is that thyroid hormones act as antioxidants. I could certainly be reading it wrong(I am not a scientist...)

from the link:

"In contrast, linoleic-acid peroxidation was inhibited by iodothyronines. Thus, low levels of iodothyronines (2.6×10−7M) are effective inhibitors of linoleic-acid peroxidation. Thyroxine and reverse T3 were found to be more effective in this antioxidant activity than vitamin E, glutathione, ascorbic acid and DTT. Since linoleic-acid peroxidation proceeds by a propagating free-radical mechanism, we have concluded that iodothyronines can effectively terminate the free-radical chain reaction to become oxidatively deiodinated. Consistent with this antioxidant mechanism, reverse T3 is effective in preserving red cell membranes as measured by the inhibition of erythrocyte hemolysis.'
