glad you posted this...i was actually going to ask you your thoughts on how you stop the calcium from lodging in other places in the body.
the tamarind for sure looks promising...hopefully i am not allergic :)
and i am curious about the lecithin too, but cannot tolerate soy plus MOST soy is really bad for you, so i won't go near it anyhow. if i find a NON soy source i will post...you do the same.
