Hi,
I would say that it is better to use IP6 than nothing, certainly. That said, there are better things for you to try. One of them is transfer factors plus (developed by 4life) which actually has IP6 as one of the ingredients -according to their baseline tests it thrashes the pants of IP6 alone. Good quality (bio-bran) MGN 3 is also, IMHO, far more potent. Other products to take a look at are Immuni -t and Oncolyn.
The name IP6 seems to be thrown around a lot (I not sure what the particular motivation is); regardless, I would check out the ones mentioned above first.
Good luck,
Conrad
