Query: Magnesium Great, Wheat not advertised a Real Problem

This product, Source Naturals 100 mg Magnesium, usually trustworthy, is not adequately described by the company selling it to include the fact wheat is a part of the Magnesium pills, even though the bottle states it very clearly. I didn't know until I'd received the bottle.I'm sensitive to wheat gluten, making this a horrible product for me, would've appreciated knowing ahead of time.Shipping costs were unreasonably high, too, and that wasn't clear until just before confirming my order. Having taken so much time, I just rolled my eyes, dreading having to shop some more, and hit "ok."Bad desriptions make the company selling this SN product unreliable. Source Naturals continues to be a reliable source of supplements, but, find a company sensitive to the needs of too sensitive people to describe products fully and appropriately.
