I found a blog about the differences in the 2 different kinds of gastric ulcers and the medication(s) that are most effective. They also talk about what measures you can take to help prevent them. Admittedly they do “push” their product but they also list and provide links to the studies they site. They also describe the ingredients in their product and why they use them. If anyone is interested it is at www.blog.biostar.com.
