Recently, my relatives had been promoting E. Excel health supplement products to my family quite aggressively.

I am not sure what kind of benefits they provide, to the extent that they claim these products boost immunity system, good for kids and even suppress cancer... 

Are these products as good as claimed? I find them VERY expensive actually. A pack of "cactus juice" is around RRM500+.

I myself is a bit skeptical with MLM products, and now my relatives have been pushing us real hard to try them, so I wonder if you guys (instead of the hardcore E-Excel members) could enlighten me a bit about their benefits (or not)? Thanks in advance.
