I looked up Kreb's Cycle Chelates, looks like an interesting product. I use other Enzymatic Therapy products, and trust the company. The full dose has a hefty amount of magnesium in it. I've used magnesium malate, and had to discontinue it because of intestinal upset from it. Is the KCC formula gentler or more easily used by the body? How and why did you start using the KCC? I hope you don't mind these questions. This is a new product to me, so I'd like to know your story with it. I need to go out tomorrow and buy more Air Power, also made by Enzymatic Therapy, so I may go ahead and get the KCC also. Thanks, Beth.
