IP6 question

Just like to ask if anyone knows the difference between inositol hexaphosphate (IP6) derived from rice bran and inositol found in (non gm) lecithin granules and what the advantages are of one over the other?
Is it a matter of higher concentration in rice bran extract or are there other factors involved?
