Have you considered also supplementing with magnesium and zinc? We usually recommend these two as well. D3, Calcium and Magnesium all important for bone and nerve health.

Not sure if it's the same formulation as what they sell to Costco. Look for "Gluten Free" on the packaging. And realize that "Gluten Free" does not mean "no gluten". It simply means not more than 20 ppm of gluten. That's fine for most celiacs but if you are of the super sensitive subset it may not be.

Trents: I read the label and it does say gluten-free. I have used these before, so will be getting some from our local Jewel. Bonus: they are Buy One Get One right now! Thanks.

Thank you. Not near a Costco. Near Jewel, Kroger, Walgreens,  Walmart,  Aldi's.  I just looked, and Jewel carries a Nature Made vitamin line. I wonder if it's the same?

Welcome to the forum, @llisa! If you are near a Costco, their Kirkland Signature brand, Nature Made and others are often gluten free and, if so, will state so on the packaging. They are economically priced as well.
