actually its hard to give a review because we think the product does us good (highly recommended by a friend who has a cancer patient son) but how do we know for sure. We are both in good health, wishing to stay that way, but cannot really tell if we feel markedly different as a result of two lots of your product. We can say we loved the promptness of the delivery, loved the packaging. However since its on trust with no identifiable results we both feel its an expensive purchase and may be hard to justify at this time (for us). Why is it so expensive ?
