There have been many questions about gluten-free vitamins - hope this
helps.

Nature's Plus from Source of Life multi-vitamin & mineral is
wheat-corn-soy-milk-preservative-sugar-starch free.  It does however,
contain barley leaf.  So far, I think I've done okay with them.  CHecking
labels, the same company's children's chewables have no barley leaf. -
