I've had stomach/digestive problems for years. Sometimes I would even wake from a deep sleep and be doubled over and almost black out. After 2 endoscopies and colonoscopies my specialist couldn't work out what was wrong so put it down to IBS and prescribed me Pariet and Colofac. Pariet, which is for high stomach acid, made me much worse so I decided to research low stomach acid and discovered that all my symptoms, including unexplained rashes, could put caused by low stomach acid. So I started taking 2 of these capsules whenever I ate a high protein meal. My stomach pain disappeared. My rashes disappeared. Amazing! Just make sure you do your research first as they can cause stomach ulcers in people who actually do have high stomach acid.
