<<Disclaimer: Verify this information before applying it to your situation.>> I emailed Country Life vitamins/supplements (which also makes the Biochem line) to ask if alpha-lipoic acid and bone density formulas are gluten-free. I received a reply from Lisa Bonsignore in their quality assurance department today. She says that they have updated their labels to indicate if the product is gluten-free, and that the information can be found on the side panel of the label. The Biochem Alpha Lipoic acid is gluten-free. So is the Bone Density formula. Vicki Jones Homewood, IL
