Yes, I have concerns about the calcium supplementation as well. Sounds like a good idea on the surface if you are trying to address bone density issues but when overdone it can have the opposite effect. Calcium supplementation increases gut PH (i.e., lowers gut acidity) which can interfere with vitamin and mineral (including calcium itself) absorption. Often, bone demineralization is not due to lack of calcium intake but to low gut acidity. This is why you will often see calcium supplement products paired with vitamin C (ascorbic acid). Drinking OJ or tomato juice along with the calcium supplement can help with this as they are acidic juices. Calcium supplementation can also contribute to plaque arterial buildup I believe. I think it might be best to focus on rich natural sources of calcium.

In that case if you answer "no" does that mean the chef doesn't have to be as diligent?  If you ask for "pork free" do they ask if it is an allergy too? How's this for an answer: "I get violently sick if I eat wheat, barley or rye"?

I order my vitamins from Pipingrock.com. They also make Cream of Rice.  Clearly marked gluten free. Right next to the Cream of Wheat. Stoneyfield Whole Milk Yogurt will help repoputate your gut bacteria.  It has lactase so is ok for lactose intolerance. 6 ounces has 210 mg calcium. For magnesium I get the 10 ounce bottle of liquid Magnesium Citrate at the supermarket or drugstore ($3).  One or two ounces of it  in a glass of water.  Add ice and sugar if you like.  I like the Cherry or Grape best. Instead try: Cream of Rice, Cheese and Good Thins (rice crackers), scrambled eggs and gluten free toast. Do you need Calcium supplement?  Calcium from supplements can cause hypercalcemia, a condition that can lead to serious health complications.  Vitamin D increases calcium absorption.  Monitor 25)(OH)D vitamin D plasma and  parathyroid hormone (PTH).    

The forms that vitamin and mineral supplements come in can be important. Bioavailability (i.e., how well they are absorbed) is often sacrificed for the sake of cost and shelf life. The vitamin or mineral you are targeting is always chemically combined with other elements to make them into a dispensable form (such as a powder, liquid or a pill) and to give them some chemical stability for shelf life.

Thank you so much! I will look for that.
