My stepdad has been taking Coral Calcium for about 4 months. He also takes MGN3 a bunch of other supplements (according to Kim Dalzell's book "Challenge Cancer and Win." He just recently (2 weeks ago) started on IP6, whey protein, a fruit pectin powder, Flax seed oil and seems to be getting his appetite back, which he lost for about 3 months and was losing weight. Research the IP6. It seems to be getting very good press. Costs about $35 at the health food stores but is about $20 on line. I would suggest the double potency if you're already taking a lot of supplements because you need to take a lot of the IP6, from what I read.
