From what I understand the UK version of Gaviscon Advance has more (alot more) algenic seaweed--the layer or raft that prevents acid from following up to your esophagus. Even the Canadian version has more of that compared to the US version. US version uses more antacid ingredients from other forums I read. Also, the Canadian and uk version should be more "safe" than the US version as they do not use aluminum. My general doc told me that I should stop taking it for awhile (more like he didn't want me to take it everyday), as aluminum build up in your body (if absorbed) can raise your risk for dementia (yay). He tried to look for something similar OTC that didn't have that ingredient, but no luck. So i told him I would try the UK or Canadian version.
Asked my friend, who on a trip to Canada to pick me up some of it up for me. Tablet of 100 costs around 18-20 USD dollars. Going to see if this helps me. (80 dollars worth). Suppose to work well at night/when you go to bed as the raft lasts several hours. And you can't eat or drink after you take gaviscon, unless you want to dissolve the raft.
You can also find gaviscon advance on amazon from a vendor from the UK. think its 8.99 + 6 dollars for shipping.
