Calcium supplementation for the nation CMAJ 1997;156:1269 In response to: W.P. Bobechko Dr. Bobechko raises an important point. Supplementation of food products such as orange juice is an important source of calcium, particularly for those who cannot or will not consume dairy products. Such products can be supplemented at a level higher than the calcium level in vegetable sources. We have been aware of the availability of calcium-supplemented orange juice in the US for some time, and we would like to see such products available in Canada. Indeed, the Osteoporosis Society of Canada has endeavoured to help make such products available in Canada, in keeping with its view that informed and educated consumers should be able to obtain dietary calcium from a variety of food choices. The society has advocated the introduction of such products to the Canadian market by consulting with corporate partners in the food and beverage industry and with the Health Protection Branch of Health Canada. However, the issue is a complicated one that still awaits regulatory approval. Topics that need to be addressed include upper safety limits for calcium intake in the general population, whether health claims can be made for such products with regard to osteoporosis, the scope of the population at risk for osteoporosis, which products should be supplemented and the benefits of harmonization with US policies. We would like to see more consumer choice and greater calcium availability through a wider variety of food sources.
