<<Disclaimer: Verify this information before applying it to your situation.>> We are looking for vitamins that are safe for sensitive responders, Specifically: 1) A multivitamin without iron, and 2) Calcium Citrate Our previous source, Nature Made, has dropped the multivitiman and changed the formulation of the calcium citrate. We looked for safe products at General Nutrition, but one of their products which is labeled gluten-free has *Oat Bran Powder* listed in the ingredients. A call to GN customer service was less than reassuring! Yikes!!! Where do they find these people!!!! We would appreciate any information concerning truly GF vitamins and will summarize to the list. As always, these are our experiences only, thus no warranty is expressed or implied, Your mileage may vary. peace steve & deni weber Valparaiso Indiana USA
