## Questions & Answers

**Q: Are there any corn derivatives additives in this?**
A: Klean Magnesium contains ascorbyl palmitate, which is derived from corn dextrose fermentation. This corn dextrose fermentation process starts with isolating dextrose from corn (a sugar, so does not contain allergenic corn protein), which is then fed to micro-organisms. The micro-organisms produce these nutrients, and the nutrients are then isolated and purified away from the starting materials. The final product is generally well tolerated by those with a corn sensitivity as the corn protein is removed.

**Q: I want the magnesium.  Is this probiotics or magnesium?**
A: Klean Magnesium is a magnesium product.

**Q: Is it buffered?**
A: Klean Magnesium is fully reacted and is not buffered.

**Q: Is it stated on the product? Why not?  "Klean Magnesium is fully reacted and is not buffered."**
A: It is a formatting choice to not include additional descriptive information for Klean Magnesium. The label states the form and the elemental amount of magnesium.
