Interesting that you mention Lecithin. She just started taking it. I'm thinking that it moisturizes the bones? Was reading that they've put radioactive Lecithin in the body to find out where it goes & one place was the bones!
Could you tell me why you think Lecithin would work for her problem? I told her I thought it was a longevity food and helps get things in & out of the cells. Nice to be able to share any further information. She's worked so hard on health, and it would be nice to give her a some hope.
Her belief system is such that she will not eat fish, unfortunately.
