Speaking with my bariatric support group leader for tonight, I found that vitamins, calcium and iron would be the topic. I researched one of my favorite sites. www.whfoods.com and found this link on calcium http://www.whfoods.com/genpage.php?tname=nutrient&dbid=45 . Look at right hand side of first page, and click PRINTER FRIENDLY note to print properly. Otherwise you won't be able to print the entire article. Good sources of calcium, drug and vitamin interractions, etc. are in this article. DAVE
