The Vitalzym does not have a direct effect on heavy metals. It will help speed up the detox process if you are using a chelator or foot pad.
The Candida die off you are experiencing is a direct result of the enzymatic activity of the vitalzym.
Yes I have heard of the Cosmic Energy Water. Most of the research was done by Dr Flanagan. I presently use a water distiller, and then reconstitute my water with microminerals and energize it with Crystal Energy drops (also known as Flanagan drops.)
The Vitalzym used over a period of time WILL eliminate scar tissue. It is usually a very positive effect, but not so with your huseband.
